Dissemination and uptake This deliverable serves primarily as a reference document among consortium partners to support the communication, dissemination, and exploitation activities of the project. It can also be used by other similar projects to draw from our planning (ambition) and implementation (experiences) so that they can in turn develop a robust CDE strategy. 3. Short summary of results This report is the second update to the DIAMOND project’s strategy for communication, dissemination, and exploitation (CDE) activities to relevant audiences, submitted one year prior to the project’s conclusion. As in the initial CDE plan described in deliverable D7.2 (and its update in D7.3), this report first defines the scope of CDE in the context of DIAMOND and sets the overall targets of the project, which aims to follow a tailored approach to develop inclusive messages and convey them to specific audiences through efficient communication means. The report also sets quantifiable indicators for specific activities that will be tracked throughout the duration of the project, such as publishing at least 10 articles and press releases throughout the project. Next, the report iterates the identification of the project’s target audiences, which include modellers, researchers, policymakers, and industries, as well as NGOs and civil society organisations. A multi-pronged selection of promotional channels/platforms is suggested, to more effectively target these varied populations. The promotional channels to reach project audiences include the project’s website, social media (e.g., X, LinkedIn, and Instagram), the IAM PARIS platform, synergies with other relevant projects, open-access papers, and more. A visual identity and a logo for the project have been developed and has been used throughout the project, including in the design of the project website and promotional materials such as infographics, presentations, and videos. The plan concludes by reporting progress towards the CDE indicators, as of September 2025, and outlines the forthcoming actions aimed at enhancing dissemination and stakeholder engagement. 4. Evidence of accomplishment This report. Page iii D7.4 – The DIAMOND Project CDE Plan – Update 2 Preface DIAMOND will update, upgrade, and fully open six Integrated Assessment Models (IAMs) that are emblematic in scientific and policy processes, improving their sectoral and technological detail, spatiotemporal resolution, and geographic granularity. It will further enhance modelling capacity to assess the feasibility and desirability of Pariscompliant mitigation pathways, their interplay with adaptation, circular economy, and other SDGs, their distributional and equity effects, and their resilience to extremes, as well as robust risk management and investment strategies. This will be done via integration of tools and insights from psychology, finance research, behavioural and labour economics, operational research, and physical science. The project will develop a transdisciplinary scientific approach to legitimise the implementation process and co-create research questions that stretch the frontiers of climate science, as well as establish vibrant communities of practice to transparently open model enhancements and to develop capacities, thereby lowering the entrance barriers to the established IAM community.

As in the initial report and its first update, this second update begins by defining the scope of communication, dissemination, and exploitation in the context of DIAMOND and by setting the CDE targets of the project. Additionally, the report sets quantifiable indicators for specific activities that will be monitored throughout the duration of the project, such as achieving 10 articles and press releases in the project’s course. Next, the report identifies the target audiences of the project as well as the promotional channels to reach them. The project audiences range from scientists/researchers/academia to decision-makers in policy/industry/NGOs, and civil society and will be further refined during the project. To reach these different audiences, a diverse selection of promotional channels is suggested. At the core of this strategy is the DIAMOND website, serving as the primary hub for information dissemination and providing access to all related promotional materials. Similarly, processes related to the continuous enhancement of the IAM PARIS platform to facilitate data harmonisation and modelling and foster the co-creation of assumptions, parameters, and scenarios, as well as host material related to the newly developed models, are briefly outlined. External communication channels are also envisioned to play an instrumental role in the project’s CDE, including social media (e.g., X, LinkedIn, and Instagram), news websites and blogs (e.g., EURACTIV and The Conversation), events such as conferences and workshops, and synergies with other relevant projects. The CDE plan also outlines the types of materials envisioned to promote the DIAMOND scope, objectives, and results through the identified channels. The visual identity and logo of the project have already been developed, based on the project’s main messages of enhancing modelling capacity to assess the feasibility and desirability of Paris-compliant mitigation pathways. This visual identity is used in the design of the project website and promotional materials, including articles, infographics, videos, and presentations. Furthermore, project updates are distributed via the project’s bi-monthly newsletters and partners' newsletters as well, which will further increase the project's visibility. The plan concludes by detailing the advancement of promotional activities undertaken throughout the project, including the ongoing development and strategic use of social media channels (X, LinkedIn, Instagram), the dissemination of the project’s objectives and progress through these platforms, and sustained engagement through participation in relevant events and conferences.

It further enhances modelling capacity to assess the feasibility and desirability of Pariscompliant mitigation pathways, their interplay with adaptation, circular economy, and other SDGs, their distributional and equity effects, and their resilience to extremes, as well as robust risk management and investment strategies. This is done through the integration of tools and insights from psychology, finance research, behavioural and labour economics, operational research, and physical science. The project develops a transdisciplinary scientific approach to legitimise the implementation process and co-create research questions that stretch the frontiers of climate science, as well as establishes vibrant communities of practice to transparently open model enhancements and to develop capacities, thereby lowering the entrance barriers to the established IAM community. DIAMOND aims to: • produce iteratively updated, upgraded, open-source versions of six leading IAMs; • further enhance the capabilities of IAMs to assess the trade-offs and co-benefits of a transition to climate neutrality with other SDGs; • enable the systematic evaluation of interactions among climate change mitigation, adaptation, risks, physical impacts; • validate the capacity of the enhanced IAMs to support climate and other development policies and COVID-19 recovery efforts at multi-level aspects; • transparently open all modelling enhancements to the wider modelling community; • develop a transdisciplinary scientific approach to co-create the research questions, legitimise the implementation process and model development, and optimise the communication of project results. This report describes the second update to the initial strategy for the communication, dissemination, and exploitation (CDE) of information and results of DIAMOND to relevant audiences. Overall, the CDE plan has the following objectives: 1. Communicating project results and successful practices to demonstrate the project’s impact to a wider audience, both online and in-person. 2. Creating the means to disseminate results to stakeholders, including policymakers, NGOs, industries, the scientific community, and even citizens, motivating them to exploit DIAMOND results. 3. Promoting the exploitation potential of the results for the six IAMs, both during and beyond the project life, through partners’ networks and ongoing activities. These objectives, along with other special requirements for DIAMOND, are described in detail in Chapter 2. In order to fulfil these objectives, the CDE plan also discusses the target audiences and their characteristics and outlines communication channels to share project results so that they are openly available and easily accessible to everyone. Additionally, the plan describes a list of methods tailored to each target group, such as communication materials, a visual identity, and social media packs for the general public, as well as external conferences and synergies and collaborations with other EU projects for academic dissemination. In summary, the CDE plan is structured based on the following questions on the promotion process: • To whom? Identification of the audiences to which the project will be promoted (Chapter 3). D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 2 • How? Analysis of potential promotional channels and selection of the most appropriate ones, according to the target audience and the message to be disseminated (Chapter 4). • What? Planning and implementation of the CDE activities (Chapter 5 for activities that are already implemented and Chapter 6 for next steps on improving dissemination). D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 9 4.1.3 Social media Social media are online forums and platforms to exchange/share thoughts, opinions, knowledge, and expertise with a large audience and can be also used to host marketing, advertising efforts, and promotional campaigns. Due to the project’s focus on so many diverse target audiences, it is envisaged that social media are and will be extensively used to promote messages and results to the wider public and relevant stakeholder groups (see also Chapter 3). Moreover, social media could offer a channel for comprehensible and accessible communication with target audiences as well as provide links to more in-depth dissemination resources. In terms of social media platforms, WP7 teams will continue to focus on using X (formerly known as Twitter), LinkedIn, and Instagram. The goal and planning for each social media channel are shown in Table 5. Table 4. Targets and plan per social media channel Social Media Purpose Plan X Increase project’s visibility in the scientific and policymaking community, as well as in the civil society At least one post per week on the project’s progress and relevant current affairs. Posts will be more frequent later in the project when more results will be delivered. News from project partners and members of the IAM community of practice are also reposted and shared. LinkedIn Increase project’s visibility in the scientific, policymaking, and business community Ad hoc posts on the project’s progress with an emphasis on model/result applications (scientific, business, policy), as well as reposting and sharing information from project partners and members of the IAM community of practice. Instagram Increase project’s visibility in the wider public Around 1-2 post(s) per month, mostly in the form of illustrations, infographics, or stories X (formerly known as Twitter) is an online social networking service in which users post and interact with short messages (less than 280 characters). It is ideal for short announcements of project outcomes. Via its X account11, DIAMOND is envisaged to reach a wide range of diverse audiences. LinkedIn LinkedIn is a business and employment-oriented social network, that allows individuals and organisations to promote their professional progress and outcomes. The DIAMOND project’s page12 on LinkedIn is used to target more specialised audiences within the scientific, policymaking, and business community and provide more detailed information about project outcomes. Instagram Instagram13 is a social networking app for sharing photos and videos, and it is ideal for communicating short and 11 https://twitter.com/climatediamond 12 https://www.linkedin.com/company/climatediamond/ 13 https://instagram.com/climatediamond?igshid=YmMyMTA2M2Y= D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 10 vivid messages to wide audiences. Our goal is to achieve more active involvement of citizens in climate action based on a better understanding and demonstration of how small-scale actions contribute to the achievement of large-scale climate policy objectives including through socially innovative approaches, and a better understanding of which actions/policies are more effective. This data will help us create more nuanced decision rules for IAMs on citizens’ willingness to change unsustainable behaviours and adopt climate-conscious practices. Citizen-led practices with high mitigation potential will be also disseminated in an accessible and user-friendly format to all stakeholders (e.g., in Instagram feeds or videos), encouraging them to share and repost them. We will also share all methodologies and tools for public engagement that will be developed in the project with the wider modelling community, to promote their exploitation. Stories can be used to ask followers questions to get feedback on their willingness to change. YouTube YouTube14 will be used for hosting and promoting DIAMOND videos, including main outputs, project events and participation in workshops. To date, three videos have been successfully uploaded. 4.1.4 News websites and blogs The following section presents a list of high-calibre media websites that can be contacted to communicate and disseminate project outputs to a wide audience. The list is indicative and non-exhaustive and will be modified or extended whenever necessary. EURACTIV EURACTIV15 is an independent pan-European media network specialised in EU policymaking, covering policy processes upstream of decisions. It provides free and localised news about EU policy in twelve languages, and together with its media partners reaches 1.7 million users across Europe and the rest of the world. The Guardian The Guardian16 is an acknowledged British daily newspaper founded in 1821 reaching a total of 24.9 million people each month. It features a section dedicated to the environment, with subtopics on climate change, wildlife, energy, and pollution. It is envisaged that the project’s outcomes can be promoted via The Guardian to a wide variety of audiences fulfilling all three pillars of promotion. The Conversation The Conversation17 is an independent source of news, analysis, and expert opinion, written by academics and researchers and delivered directly to the public. It is estimated that its global audience is about 14.1 million readers per month. It is envisaged that project results can be promoted via The Conversation to audiences appropriate for dissemination and exploitation. ClimateChangePost ClimateChangePost18 features the latest news on climate change and adaptation with a special focus on Europe. 14 https://www.youtube.com/@climatediamond 15 https://www.euractiv.com/ 16 https://www.theguardian.com/ 17 https://theconversation.com/ 18 https://www.climatechangepost.com/ D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 11 Many of its articles present the latest results from scientific publications and reports, making it an ideal conduit for DIAMOND to reach a wide range of its target audiences. ClimateChangeNews.com An international platform19 that covers climate change news, analysis, commentary, video, and podcasts focused on developments in global climate politics. Euronews – Climate Now For dissemination to a very wide audience, the Climate Now20 programme of the Euronews channel may be a good fit for DIAMOND. Energypost.eu Energy Post21 provides an open platform to exchange and debate energy topics for policymakers, market players, analysts, and other stakeholders and could be used to reach specialised audiences for project results. 4.1.5 Magazines Research*eu Research*eu Results magazine22 covers topics of research interest in the EU. Through this magazine, results of DIAMOND can be communicated and disseminated to scientists, policymakers in the EU and Member States, and the general public. 4.1.6 Online collaboration and sharing platforms Climatechangemitigation.eu Climatechangemitigation.eu is a portal that collects and disseminates information from different EU-funded research projects on climate change mitigation. DIAMOND will use the portal23 to promote its results to scientific and policymaking communities working on mitigation topics. REScoop.eu REScoop.eu24 is a growing network of 1.900 European energy cooperatives and their 1.250.000 citizens who are actively participating in the energy transition. DIAMOND will use this channel to communicate and disseminate results but also recruit potential stakeholders for co-creation activities. Energy Cities Energy Cities25 is a network of 1,000 local governments in 30 countries that establish a trustful dialogue between citizens, local leaders, and EU & national institutions to accelerate the energy transition in Europe. As with RESCOOP.eu, DIAMOND will contact Energy Cities to promote announcements related to the dissemination of 19 https://climatechangenews.com/ 20 https://www.euronews.com/green/green-series/climate-now 21 http://energypost.eu/ 22 https://cordis.europa.eu/research-eu/home_en.html 23 http://climatechangemitigation.eu/ 24 https://www.rescoop.eu/news-and-events 25 https://energy-cities.eu/ D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 12 project outcomes, but also to the recruitment of participants for its activities. Capacity4Dev Capacity4Dev26 is the European Commission’s knowledge-sharing platform for development cooperation aiming to improve capacity building. The platform has over 25,000 members who share, learn, and collaborate on the fields of sustainable development. This channel is ideal for dissemination and exploitation purposes since its members are scientists, industrialists, EU staff, sustainable development professionals in the EU, policymakers at the EU and global level, as well as members of civil society. IISD SDG Knowledge Hub The SDG Knowledge Hub27 is an online resource centre for news and commentary regarding the implementation of the United Nations’ 2030 Agenda for Sustainable Development, including discussions on progress across all 17 Sustainable Development Goals (SDGs). It is envisaged that our outcomes can be promoted via the IISD SDG Knowledge Hub to actors involved in sustainable development, such as policymakers, scientists, NGOs, industrialists, and civil society. ECEEE The European Council for an Energy Efficient Economy28 is a non-profit, independent organisation dedicated to promoting energy efficiency in Europe. Since a major modelling improvement that DIAMOND will undertake relates to behavioural change towards reducing energy demand, ECEEE can be contacted to promote relevant outputs to policymakers, businesses, and NGOs related to energy efficiency. 4.1.7 Data repositories and platforms Zenodo Zenodo is a platform developed by CERN with the goal to provide an easy-access data repository for scientific data from all over the world and from every discipline. The DIAMOND Zenodo community29 will form a central hub for providing open and unrestricted access to the project’s publications and data. GitHub GitHub30 is a platform for hosting open-source code, allowing extensive functionalities for version control and collaboration. GitHub will be used to host the code for new model functionalities that will be developed as part of DIAMOND31, as well as scripts and inputs that will be used in the project’s modelling exercises. OpenAIRE OpenAIRE32 is a science-related portal, the mission of which is to provide unlimited, barrier-free, open access to research outputs financed by public funding in Europe. The use of OpenAIRE will enable DIAMOND, on one hand, 26 https://europa.eu/capacity4dev/ 27 http://sdg.iisd.org/ 28 https://www.eceee.org/ 29 https://zenodo.org/communities/diamond/?page=1&size=20 30 https://github.com/ 31 https://github.com/CLIMATE-DIAMOND 32 https://www.openaire.eu/ D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 13 to report more effectively and efficiently the scientific, and other, outcomes of the action and, on the other, to reach a wide community of scientists, policymakers, and stakeholders interested in EU-funded research in general. European Open Science Cloud The European Open Science Cloud (EOSC)33 aspires to provide European researchers, innovators, companies, and citizens with an open multi-disciplinary environment where they can publish, find and re-use data, tools and services for research, innovation, and educational purposes. 4.1.8 Partners’ websites/blogs Most consortium partners have websites featuring news on their research activities. On these websites, articles on the progress of DIAMOND and announcements on recent reports or upcoming events will be published. Partners’ websites that had already published about the start of the project include the websites of ETH Zurich34, HOLISTIC35, and ICSS36. Other partner websites that could be used in the future for dissemination and communication include the websites of BC337, CESAR38, CICERO39, CYI40, EASMA41, COMILLAS42, ISINNOVA43, SEURECO44, UM45, ESMIA46, UMD47, EPLF48, UNIBAS49, Imperial50, Oxford51, and UCL52. Project activities could also be promoted through partners' social media accounts. 4.1.9 Peer-to-peer mailing lists Peer-to-peer (P2P) mailing lists are subscription-based email services that enable individuals interested in specific topics to communicate with each other and exchange opinions and project results. P2P lists related to DIAMOND project-related topics such as energy, IAMs, transdisciplinarity, and climate change mitigation can be powerful means to reach audiences from academia, policymaking, and business since most subscribers are actively working in sectors affected by these topics. These lists will be used to disseminate the project’s progress and output (newsletters, press releases, and general announcements) and invite subscribers to participate in DIAMOMD’s 33 https://eosc-portal.eu/ 34 https://ethz.ch/en.html 35 www.holisticsa.gr 36 https://www.iccs.gr/en/institute-of-communication-and-computer-systems/ 37 www.bc3research.org 38 https://www.cesarecon.at/language/de/ 39 www.cicero.oslo.no 40 https://www.cyi.ac.cy/ 41 www.e4sma.com 42 https://www.comillas.edu/en/ 43 https://www.isinnova.org/about-2/history/ 44 www.erasme-team.eu 45 https://www.maastrichtuniversity.nl/ 46 https://esmia.ca/ 47 https://www.umd.edu/ 48 http://www.epfl.ch 49 https://www.unibas.ch/en.html 50 http://www.imperial.ac.uk 51 https://www.ox.ac.uk/about 52 https://www.ucl.ac.uk/ D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 14 open events and webinars. Additionally, these mailing lists will be used to follow research and novelties from project-relevant fields.53 4.1.10 External events With the aim to effectively promote DIAMOND, partners will be encouraged to participate in events organised outside the consortium and promote preliminary and final results, both during and after the end of the project. This includes events organised by the European Commission as well as international conferences and workshop fields related to the project’s scope. All partners will participate in the identification of relevant events. Scientific conferences DIAMOND partners will participate in scientific conferences to disseminate the project results to the scientific community. Additionally, conferences will be used to monitor relevant research in fields related to energy citizenship and other relevant topics. The following conferences have been assessed as relevant to the project: • European Climate + Energy Modelling Platform (ECEMP)54 • Annual Meeting of the Integrated Assessment Modelling Consortium (IAMC)55 • International Energy Workshop56 • Energy Modeling Forum57 • International Transdisciplinary Conference58 • Sustainable Development of Energy, Water and Environment Systems (SDEWES) conference59 • Annual Conference of the European Association of Environmental and Resource Economists (EAERE)60 Policy conferences Along the duration of DIAMOND from December 2022 to November 2026, four sessions of the UNFCCC’s Conference of the Parties (COP) had and will take place. These conferences offer great opportunities to reach out to policymakers, NGOs, industrialists, scientists, and other audiences and promote the project. In terms of European-specific conferences, the European Sustainable Development Week61 and the European Sustainable Energy Week62 will be policy-relevant fora for presenting the project’s results. Workshops and other events and media A series of workshops with key stakeholder groups will take place in the context of the modelling work, to inform our activities and outcomes and ensure their relevance. These workshops will also serve as dissemination fora, where knowledge and information generated will be shared and discussed. A final EU conference will take place to inform policy, other stakeholders, and the broader modelling research community on the project’s IAM 53 https://enb.iisd.org/email/ 54 https://www.ecemf.eu/ecemp/european-climate-and-energy-modelling-platform/ 55 https://www.iamconsortium.org/annual-meetings/ 56 https://www.internationalenergyworkshop.org 57 https://emf.stanford.edu 58 https://akademien-schweiz.ch/en/current/events/itd-conference-2021/ 59 https://www.sdewes.org/ 60 https://www.eaere.org/ 61 https://esdw.eu 62 https://sustainable-energy-week.ec.europa.eu/index_en D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 15 improvements and advanced, sustainable mitigation pathways. Building on lessons learnt from the COVID-19 pandemic, most workshops in the context of the co-design nature of the DIAMOND project will be organised in a digital format. This will help to avoid the environmental and economic impact of travelling, while also circumventing potential travel restrictions due to pandemic-related restrictions, as well as reducing the time investment from the participants. 4.1.11 Synergies Synergies with relevant projects can increase the outreach potential of the project’s outputs and raise awareness among a broad spectrum of stakeholders. DIAMOND will contact projects of interest and co-organise synergetic activities such as participating in each other’s events and cross-disseminating information and outputs through social media and project websites. DIAMOND has already established connections with the WorldTrans63 sister project, where the project coordinator (Dr Cecilie Mauritzen) of WorldTrans has been invited to the DIAMOND Scientific Advisory Board (SAB) and vice versa. Additionally, the NTUA section of ICCS is coordinating the IAM COMPACT project, which is focusing on the same domain of climate change mitigation as DIAMOND and will run in parallel, offering many options for synergies between the projects. The DIAMOND website already contains a section on such synergistic activities64. In parallel with co-creation activities with other research projects, DIAMOND aims to enhance communities of practice for climate-economy modelling. We will establish active channels for two-way communication and synergies with existing modelling consortia and communities such as IAMC65, GCAM Community, and IEAETSAP66. We will go beyond the usual synergies among such communities by aiming to encourage an open-source development process for the project’s improved IAMs with the collaboration of external modellers. 4.2 Branding and promotional materials Several types of promotional materials are envisaged to promote the DIAMOND project scope, objectives, and results in different stages of the project. All promotional materials have a consistent and distinctive visual identity and have been created within the first six months of the project67. 4.2.1 Visual identity and communication package Visual identity and logo A simple but distinctive and appealing visual identity (D7.1) has been developed at an early stage in the project. The logo was custom-made for DIAMOND, and its blue and yellow hues were chosen intentionally. Blue is the most universally appealing colour on the spectrum because of its non-polarising traits; it is usually used in corporate logos related to software, finance, and technology as it creates a sense of security while showing professionalism. Yellow shows optimism and enlightenment but also caution, while brands that are seeking to draw in consumers with youthful energy often utilise this colour. In addition, the project’s relation with the six IAMs also be depicted on the logo, as the shapes are six in number, and all together create a diamond of models. 63 https://sites.google.com/met.no/worldtrans/home 64 https://climate-diamond.eu/open-science/synergies/ 65 https://www.iamconsortium.org/ 66 https://iea-etsap.org/ 67 https://climate-diamond.eu/communication/visual-identity/ D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 16 Figure 1. DIAMOND project logo Templates Throughout the duration of DIAMOND, there will be a variety of documents circulated among partners, disseminated to stakeholders, published on social media, or printed and shared at events. In order to consolidate the DIAMOND project visual identity and ensure uniformity and recognisability, specific templates have been and will be created for each document type using the same colours and styles across all material. Examples of such document templates include Microsoft Word templates for project deliverables (used in the current document) and other types of reports as well as Microsoft PowerPoint templates for presentations. An updated visual identity will also be developed for the policy briefs in order to provide concise information to policymakers along with attractive visuals. Flyer A promotional flyer has been developed giving general information and creating visibility about DIAMOND68. It has been primarily produced in English and is translated into all partners’ languages. As with all communication package items, the flyer is available online on the project website and will be downloaded and printed only when needed. Leaflet DIAMOND has also produced a promotional leaflet, featuring a short project description, that is intended for dissemination at conferences and other events69. The promotional leaflet concisely describes the project’s aims, objectives, contents, and expanding capabilities and participants linked to current events in order to spark interest. A revised version will include results, modelling activities, lessons learnt, and policy recommendations. Poster A publicity poster on DIAMOND has been created and will be used at events organised by the partners or hosted by other relevant organisations70. Institutional presentation A standard presentation about DIAMOND has been created, containing basic information about the project’s objectives, activities, partnerships, and events, and will be used for dissemination at conferences and other relevant events71. Videos and infographics The WP7 team will produce videos and infographics to create awareness and familiarity with project results 68 https://climate-diamond.eu/wp-content/uploads/2023/04/Flyer_ENG_April.pdf 69 https://climate-diamond.eu/wp-content/uploads/2023/04/Leaflet_ENG_April.pdf 70 https://climate-diamond.eu/wp-content/uploads/2023/04/Poster_April.pdf 71 https://climate-diamond.eu/wp-content/uploads/2023/03/Diamond_Template.pptx D7.4 – The DIAMOND Project CDE Plan – Update 2 Page 17 (especially among non-experts). 4.2.2 Promotional materials Blog posts, articles, and press releases Articles on climate action and energy strategies in leading media websites and blogs will be disseminated via the promotional channels identified in Section 4.1. Additionally, press releases will be developed by the WP7 team, disseminated through the website’s newsletter, and promoted to relevant media. All partners will support this process by suggesting media contacts at the national level and extending the list of interesting media targets. At least 10 articles and press releases are expected to be published during the project’s course. Scientific publications Scientific publications are one of the key means of disseminating the project’s results to the research community and building scientific credibility for the project’s work. Scientific articles will be published in open-access, highquality, peer-reviewed journals. Partners will also be encouraged and assisted in publishing their results in working paper series. These activities will ensure that the project and its results will be made known to the public at large. Journals also offering open peer review, such as Open Research Europe, will be considered as a possible outlet. In the case of hybrid or transformative journals, the gold open access option will be selected, and the APC will be immediately covered via institutional agreements of participating organisations. Access to papers and supporting datasets will be made immediately available in a dedicated project OpenAIRE/Zenodo community, using Creative Commons licenses for reusability and DOIs for findability. Moreover, the WP7 team will use its social media channels to promote the articles. A special issue is also envisioned using the consortium partners' connections to respective journal editors to further support the scientific dissemination and exploitation of the project’s results. DIAMOND newsletter The newsletter’s goal is to create awareness and involve stakeholders in progress. A regular electronic newsletter is issued providing information on the project development and events every 2-3 months. The newsletter will incorporate inputs from all partners on the progress and key outcomes of the project. Its key aim is to create awareness about the ongoing work of the action and involve stakeholders in progress. In compliance with the GDPR, a person will be included on the newsletter mailing list only if one is informed and explicit consent has been given, while the possibility of withdrawing the consent is clearly explained. Consent will be provided either by filling out an online subscription form or by direct email in case of personal contacts. Press releases at partners’ institutions DIAMOND provides regularly the communication departments of all consortium partners with content to be processed for the partners’ newsletters, websites, and other media channels. Page 18 D7.4 – The DIAMOND Project CDE Plan – Update 2 5 Implemented activities as of September 2025 During the first 34 months of the project, several CDE activities have been implemented. Nevertheless, dissemination efforts are expected to intensify during the next year when most deliverables and scientific products of DIAMOND will be available. As of September 2025, 23 out of the 50 project deliverables have been finalised (including this report). For now, the WP7 team aimed to establish a strong presence on social media, creating weekly posts derived from the project’s concept and methodology. Figure 2 shows the project’s CDE tracker, including a selection of implemented activities. The tracker is used to monitor and document events and media activities of the project; it is available online72 and is frequently updated. The following sections show implemented activities in more detail. Figure 2. Screenshot of project tracker for CDE monitoring 5.1 Progress towards CDE indicators Table 5.

[session chair] Additionally, 10 internal events have already been organised by the DIAMOND team, including general meetings and meetings between the modelling teams of the project (see Figure 6 for screenshots from these meetings). Details about the major meetings can be found on the website82 while the full list of events can be found on the dissemination tracker83. In the coming years, DIAMOND partners are expected to organise and participate in even more events, helping to build communities of practice in climate modelling and to promote project results. Figure 6. Photos from events that DIAMOND has participated in as of May 2024 Finally, in the context of WP6, DIAMOND has organised the following webinars for the modelling community (see Figure 7 for screenshots of their banners): 1. Stakeholder Participation in IAMs: In February 2025, the project DIAMOND organized a webinar on “Demystifying stakeholder participation in integrated assessment modelling and scenarios”. The webinar was especially intended for modellers using, as well as social scientists working with, IAMs and other climateeconomy models, and aimed to provide an opportunity for exchanging practices and sparking potential synergies and initiatives on the topic. 2. The past and future of scenarios in the IPCC: DIAMOND project organized a webinar on “The past and future of scenarios in the IPCC” on Tuesday, 17 June 2025. This webinar was intended for researchers engaged in climate scenario development and assessment, especially those working with IAMs, energy-economy models, and broader scenario exercises. It provided a space to reflect on how scenarios had developed over time, explored opportunities to expand the modelling and scenario landscape, and considered how a more inclusive and pluralistic approach could enrich future assessments. 82 https://climate-diamond.eu/news-events/ 83 https://docs.google.com/spreadsheets/d/1fUFBQVm8JBMrAVg7ENTi0YoxOqOJ8mAPU6oeEIyMlhQ/edit?usp=sharing Page 29 D7.4 – The DIAMOND Project CDE Plan – Update 2 Figure 7. Banners from the two DIAMOND WP6 webinars Additionally, DIAMOND participated in the “Seminar Series 2025 #3” (Figure 8), which is part of the monthly seminars from the Coupled Model Intercomparison Project (CMIP), with colleagues from CICERO presenting the METEOR model to more than 30 participants. Figure 8. DIAMOND in the CMIP seminar series, presenting the METEOR model 5.7 Synergies Several synergies have already been established between DIAMOND and relevant European projects84. The majority of the 28 journal publications that are currently acknowledging DIAMOND have been published as a synergy with other projects, most notably, the Horizon 2020 PARIS REINFORCE and the Horizon Europe IAM COMPACT. Additionally, on 17 April 2024, DIAMOND co-organised along with its sister project WorldTrans a presentation on the design of an interactive policy platform for climate change mitigation and adaptation. The meeting also included a discussion on further synergies between WorldTrans and DIAMOND (Figure 9). 84 https://climate-diamond.eu/open-science/synergies/ Page 30 D7.4 – The DIAMOND Project CDE Plan – Update 2 Figure 9. Example of synergies between WorldTrans and DIAMOND (discussed during April 2024) DIAMOND also participated in the MAIA Multiply programme, organised by the Horizon Europe MAIA project85 which served as an aggregator and amplifier of the results of Horizon projects on climate topics (see Figure 10 for an example). MAIA also provided networking opportunities and CDE advice to participating projects, further increasing the impact of DIAMOND to its target audience. Since MAIA has already concluded by September 2025, DIAMOND has been included in the interactive synergy map of Climate Research Communication Network and has already participated in joint webinars and could pursue more science communication-related synergies during its last year 86. Figure 10. The MAIA multiply program that DIAMOND is participating in Finally, various DIAMOND partners participated in the final event of IAM COMPACT which took place in August 2025 in the Acropolis Museum in Athens, presenting findings from synergistic exercises as well as the overall approach of the project. 85 https://maia-project.eu 86 https://www.esm2025.eu/science-policy-partnership/climate-research-communication-network/ Page 31 D7.4 – The DIAMOND Project CDE Plan – Update 2 5.8 Newsletters and press releases By the end of September 2025, the dissemination team of DIAMOND has sent ten newsletters and seven press releases in English, targeting 1879 English-speaking recipients. Newsletters were typically released after significant project events and provided updates and website links to all recent activities and outputs of DIAMOND, such as conferences, workshops, and scientific publications. Press releases were kept mainly for significant announcements that warranted a separate, dedicated release to showcase them. For more details on the contents of each newsletter and press release, see our website87. Indicative screenshots of newsletters and press releases are included in Figure 11 below. The implemented strategy has so far resulted in a higher than anticipated opening rate (39%), validating that the topics sent are of interest to the community, without overburdening the recipients. With the delivery of the first versions of the models (as illustrated in the latest press release; September 2025), as well as the progressive delivery of the final versions of the models and the scenario exercises, more opportunities for additional material are expected. Figure 11. Indicative screenshots of the DIAMOND newsletter 5.9 Infographics and videos Infographics have been developed catching the pulse of the FIFA World Cup 2022 and building up audience for project social media accounts. We produced several infographics showcasing the greenhouse gas emissions of countries participating in the World Cup. Figure 12 shows an example, while all infographics are available on the 87 https://climate-diamond.eu/communication/newsletters-press-releases/ Page 32 D7.4 – The DIAMOND Project CDE Plan – Update 2 project website88. More infographics will be developed when more project materials become available. The upcoming delivery of the final versions of the models, and their use on scenario exercises will be exploited to deliver technical briefs which can then be converted into dedicated infographics. Figure 12. Infographics for FIFA World Cup 2022 As explained in Section 4.1.3, DIAMOND maintains an active account on YouTube, uploading videos from the webinars organised and described in Section 5.3. Links to these videos are also provided in the project’s website89, which additionally includes videos from further sources related to DIAMOND participation (Figure 13). So far, four videos have been uploaded: • A brief DIAMOND introduction • The “Demystifying stakeholder participation in integrated assessment modelling and scenarios” webinar • The “The past and future of scenarios in the IPCC” webinar • The presentation of the METEOR model from the CMIP seminar. 88 https://climate-diamond.eu/communication/infographics/ 89 https://climate-diamond.eu/communication/videos/ Page 33 D7.4 – The DIAMOND Project CDE Plan – Update 2 Figure 13. Videos from the: a) METEOR presentation on the CMIP seminar; and b-c) the two webinars organised. Page 34 D7.4 – The DIAMOND Project CDE Plan – Update 2 6 Next steps and final event Throughout the duration of DIAMOND, the primary objective of the CDE plan has been to establish a strong project identity and online presence by developing its visual branding and website, building a solid social media following, and producing initial communication materials—such as event updates and publication highlights. This goal has been successfully achieved, as evidenced by the current size of the project’s audience on LinkedIn (682 followers, exceeding the KPI of 500), Instagram (474 followers), and X (658 followers), along with 3,300 unique website visitors recorded over the past 12 months (surpassing the KPI of 2,000 visitors). Dissemination could further ramp up during the final months of the project in order to attain the intended CDE performance, for instance, improving the rate of returning visitors (currently 10% against a target 40%). Additionally, DIAMOND has built its networks with significant modelling consortia (e.g., IAMC, ECEMP, and the GCAM community) and relevant projects (e.g., IAM COMPACT, TRANSIENCE), leading to publications developed as synergies between DIAMOND and these projects. It is expected that these collaborations will amplify in the coming years as more scientific outputs and, thus, more opportunities for synergies will become available. In addition to the growing availability of the content for dissemination, the WP7 team aims to take the following actions to further improve the CDE performance of the project: Website: More content will be included in the coming months, such as deliverables, publications, videos, and infographics. All project deliverables will be made publicly available during the final year of the project. In addition, over the coming months, new content will be released—including deliverables, publications, videos, and infographics—to highlight the project's progress and key outcomes. Social media: The WP7 team will continue to post at least once a week on social media. This dissemination is expected to intensify as research outcomes of the project become available. The WP7 team will also become more active on Instagram by developing and posting visual material and infographics that promote the project and its outcomes. Expanding social media impact is a priority, with a focus on launching coordinated thematic campaigns around key milestones such as model releases and major publications. These campaigns will use visual content, strategic partner tagging, and active community engagement to drive interaction and follower growth. On Instagram, increasing the frequency of posts through weekly visuals and stories, along with the introduction of interactive features such as polls and Q&As, will help raise awareness and deepen engagement among broader audiences. Media: Along with efforts to intensify social media presence, the WP7 team will produce at least 10 articles for media outlets and blogs. The articles will be based on the research outputs of the project and will aim to both increase awareness about DIAMOND and its goals and also contribute to attracting audiences beyond academia and research. The online presence of DIAMOND will be further strengthened in the upcoming period. This effort is expected to increase traffic to the project website and improve its search engine optimisation (SEO) through enhanced backlinking. Published articles will cover topics related to key DIAMONDS deliverables, focusing on content that is both engaging and relevant to a broader audience—including the final outcomes of the project. Publications: Building on the project's 28 scientific papers produced by September 2025, publications are expected to be increased with the delivery of the models (methodological advancement papers; at least 20 such papers in total) and the scenario exercises (policy-relevant papers; at least 10 such papers in total) during the final year of the project. Policy Briefs and Business Guides: In the final phase of the project, we will develop 6 policy briefs and 2 business guides based on the produced mitigation pathways (and potentially featuring technical briefs on the capabilities of the new models developed). These will consider underexplored interactions with extreme events, circular
