Exploring National and Global Actions to reduce Greenhouse gas Emissions (ENGAGE)

To develop optimal climate policies to deliver on the Paris Agreement, a consortium of 25 international and multidisciplinary research groups are collaborating to co-produce knowledge for designing cost-effective, technologically sound, socially and politically feasible pathways that can meet the objectives of the Paris Agreement. 



As the world faces the risks of dangerous climate change, policy-makers, industry and civil society leaders are counting on Integrated Assessment Models (IAMs) to inform and guide strategies to deliver on the objectives ofthe Paris Agreement (PA). ENGAGE rises to this challenge by engaging these stakeholders in co-producing a new generation of global and national decarbonization pathways.

These new pathways will supplement natural science, engineering and economics, traditionally represented in IAMs, with cutting-edge insights from social science in order to reflect multidimensional feasibility of decarbonization and identify opportunities to strengthen climate policies. The pathways will be designed to minimize overshoot of the temperature target and analyze the timing of net-zero emissions to meet the Paris temperature target and reduce the reliance on controversial negative emissions technologies. In addition, they will link national mitigation strategies of major emitters with the PA’s objectives, integrate potential game-changing innovations, and advance conceptually novel approaches to architectures of international climate agreements.
