Enhanced integrated assessment in pursuit of global climate goals

Open Call Reference: HORIZON-CL5-2021-D1-01-04


Under the Paris Agreement, Parties to the UNFCCC have to pursue policies and measures to reduce their greenhouse gas emissions, including by preparing and implementing successive Nationally Determined Contributions (NDCs) towards the Agreement’s objectives. By 2025, countries are expected to produce new NDCs covering the post-2030 period, informed during the 2022-23 period by the 6th Assessment Report of the IPCC and the Paris Agreement Global Stocktake.


– Provision of information for the preparation of climate policies and national planning for the post-2030 period, in light of the Paris Agreement goals and the need to reduce global net greenhouse emissions to zero by 2050.

– Enhanced international cooperation among the modelling community and other relevant stakeholders to expand the provision of robust in-country advice to decision-makers around the world.

– Enhanced mutual learning among the modelling, social science and policy communities to ensure coherence between different tools used to inform climate action, and consistency with the best available and open science.


– Ensure that Integrated Assessment Models enable the assessment of Paris Agreement-compatible mitigation policies to which policymakers around the world have access.
– Deliver advice and insights that can inform climate action and sustainable development policy design, including biodiversity preservation, at global and national level, based on the best available science.
– Support comparability of model results e.g. between national and global scenarios, and between Integrated Assessment Models and other models used to inform climate action at different geographical scales.
-Identify milestones, drivers and barriers towards achieving climate neutrality in an economically and environmentally responsible and socially inclusive way, including where appropriate by examining implementation of previous or existing climate policies.
-Consider the role of major sectors including energy, water, transport, industry and land use, as well as the sequence of individual, social, economic, structural, and technological changes that could lead to climate neutrality.
-Support the use of model-based and data/driven analysis for climate-policy in the context of sustainable development and recovery from the economic and social impacts of the COVID-19 pandemic.
-Share best practices and build capacities to support the production of national scenarios and to inform domestic stakeholders during and after the lifespan of the action.
