Tracking, evaluation and comparison of climate change mitigation policies and actions from a wide range of stakeholders to support ambition-raising efforts.


Policies are evaluated, tracked and compared against the internationally agreed 2C target.
Policies are evaluated, tracked and compared against the internationally agreed 2/1.5°C limit.

Action to combat climate change is diverse. National governments, regions, cities, companies and individuals embark on the challenge to reduce emissions. We develop and apply methods to monitor climate change mitigation action and commitments between peers and evaluate collective progress towards the objective of holding global warming below 2/1.5°C.

NewClimate Institute staff has years of experience in the evaluation of mitigation commitments and policies, and analysis of their effect on emissions. We connect to policymakers, practitioners and researchers all over the world to identify best practices and provide cross national insights on strategies to keep the Paris Agreement’s long-term goal within reach.

Flagship projects include the Climate Action Tracker, Climate Change Performance Index, and global aggregation of subnational and non-state climate actions.
