There is an urgent need to strengthen collective action to limit global warming to levels consistent with the long-term objective of the Paris Agreement. The NEWPATHWAYS project aims to inform solutions to strengthen action by developing and analysing next-generation Paris-aligned global and national low-emission transformation pathways for the next global stocktake in 2028. The project objectives are to promote enhanced transparency, consistency, and clarity of GHG emission reduction commitments, identify opportunities to leverage equity and finance to strengthen collective climate action, and establish new national and global transformation pathways that limit temporary overshoot, rely on deep sectoral transformations, combine climate and nature protection, and are aligned with sustainable development and just transition objectives. The project will rely on a multi-level stakeholder dialogue to co-create knowledge and build user capacity to maximize relevance and uptake of its results. The NEWPATHWAYS consortium combines strong global and national pathway modelling capacity with expertise from the social sciences, economics and policy analysis. National modelling teams come from a diverse set of countries in the Americas, Asia, Africa and Europe covering two thirds of global greenhouse gas emissions. The robust global and diverse national modelling capabilities with simultaneous access to global and national policy debates will prove effective in providing critical information to global and national policymakers and stakeholders for strengthening climate action towards achieving the long-term objective of the Paris Agreement.
