ENGAGE is a global consortium of international and multidisciplinary leading research groups, that is coordinated by IIASA, aims to co-produce knowledge for designing cost-effective, technologically sound, socially and politically feasible pathways that can meet the objectives of the Paris Agreement. ENGAGE will also quantify avoided climate change impacts at the regional and national levels and identify concrete policy portfolios that maximize co-benefits and minimize trade-offs.
Knowledge co-production will be achieved through an iterative stakeholder dialogue process that will include workshops, surveys and frequent interactions and feedback among scientists, policy makers, civil society, the private sector, and other key stakeholders. ENGAGE will be inclusive of major emitters and selected developing countries which will ensure the credibility and legitimacy of the scientific and policy insights.
ENGAGE will also address a historical shortcoming of IAM-based pathways — insufficient attention to social, political, and certain technological constraints and enablers of mitigation efforts — by developing and operationalizing the concept of multidimensional feasibility of decarbonization policies and pathways. To accomplish this, ENGAGE will utilize empirical analysis, statekholder dialogue, and conceptual insights from the social sciences to develop a tool which will subsequently be used to assess and improve the feasibility of decarbonization pathways.
ENGAGE will quantify avoided climate change impacts through analysis of the exposure and associated costs for individual sectors and regions to climate change at different levels of and timing for global peak temperature. A particular focus will be on quantifying the benefits (or trade-offs) of climate policies on biodiversity, food, poverty, water, air quality, health, and employment, particularly for vulnerable populations.
ENGAGE works in close collaboration with its sister project: Next Generation of Advanced Integrated Assessment Modelling to Support Climate Policy Making (NAVIGATE).
