The DIAMOND project aims to contribute to the development of the next generation of integrated assessment models (IAMs), which will be fully open and sufficiently equipped to scientifically underpin and support an accelerated transition towards circular, resilient, desirable, and sustainable climate neutrality.

DIAMOND has the following six project objectives (O):

O1. To produce iteratively updated, upgraded, open-source versions of six leading IAMs

by significantly increasing their sectoral and technological detail, spatial and temporal resolution, EU-level granularity, robustness, and capacity to represent structural changes, extremes, and behavioural changes

O2. To further enhance the capabilities of IAMs

to assess the trade-offs and co-benefits of a transition to climate neutrality with other SDGs, including biodiversity, health, well-being, and food security, as well as to explore the political feasibility and societal desirability of mitigation pathways, the distributional and equity effects of climate policies, alternative economic paradigms, climate risk management, and investment strategies, through fully fledged multi-model integrated frameworks and systematic interdisciplinary interactions with tools and insights from psychology, behavioural economics, labour economics, finance and economics research, operations research, and the broader field of social sciences & humanities

O3. To enable the systematic evaluation of interactions among climate change mitigation, adaptation, risks, physical impacts

by coupling these IAMs with climate and biosphere management models and providing risk framings of produced scenarios, thus creating robust, fully integrated assessment frameworks

O4. To validate the capacity of the enhanced IAMs

towards supporting climate and other development policies and COVID19 recovery efforts at global, European, national, and regional level as well as substantially contributing to international scientific assessments for climate change, biodiversity, and resource conservation, by inter alia expanding the scenario space and uncertainty spectrum

O5. To transparently open all modelling enhancements to the wider modelling community

by developing tools, protocols, and methodologies to expand project improvements to other IAMs outside the project consortium, and by increasing their usability and relevance for modelling teams, policymakers, and other stakeholders via capacity development efforts and building communities of practice in science, policy, and society

O6. To 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, with representatives from policy, business, and civil society, allowing to translate the motives, concerns, and actions of decision-makers and citizens over climate action in measurable, quantifiable terms and to demonstrate how they can affect and contribute to the wider climate policy and sustainable development objectives
