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

Associated projects
Advancing the COMPASS toolbox to assess climate action
Under this project we have advanced NewClimate’s COMPASS suite of tools which are design to help analysts and decision makers navigate a range of climate action impacts.
NDC Design
Systematic analysis Return to all expertise and projects As part of the Paris Agreement, countries are mandated to update and enhance their Nationally Determined Contributions (NDCs) every five years—increasing their ambition with every cycle.

In a consortium with Climate Analytics and Ecofys, NewClimate Institute contributes to the Climate Action Tracker’s Scaling Up Climate Action country series. The first round of our analysis covers South Africa, the European Union, Indonesia, Turkey, Argentina, and Australia.
Climate Action Tracker – Climate Governance Series
Developing a framework for assessing countries’ readiness to implement ambitious climate policy.
Climate Change Performance Index
The Climate Change Performance Index is an instrument to enhance transparency in international climate politics. It aims to encourage countries which have, up to now, failed to take ambitious actions on climate protection as well as to highlight countries with best-practice climate policies.
Pathways and entry points to 1.5 °C (PEP1p5)
The project aims to develop a scientific and policy relevant assessment of the long-term goal to limit global temperature increase to 1.5°C in the Paris Agreement.

NewClimate Institute is analysing the aggregate impact of non-state and subnational actors (cities, regions and businesses) around the world on greenhouse gas emissions.
Implementation of future GHG mitigation goals: Framework conditions and transformative challenges in selected focus countries
In this project NewClimate together with Wuppertal Institute has compiled and analysed quantitative and qualitative information on climate protective policies and actions as well as future options for deeper emission cuts in Ethiopia, Georgia, Indonesia, Iran, Kenya, Colombia, Morocco, the Marshall Islands, Peru and Vietnam.

The aim of this brief analysis was to translate the goals of the international climate regime as determined by the Paris Agreement into the German context.
Climate Transparency
Climate Transparency is an open global consortium with a shared mission to stimulate a ‘race to the top’ in climate action through enhanced transparency. For this purpose, comprehensive, comparable and credible information about government climate action is spread by bringing together the most important actors in assessing and communicating climate action for the benefit of key influencers and decision makers.
International Cooperative Initiatives (ICIs) outside the UNFCCC
Evaluation of the impact of global, regional and national initiatives outside UNFCCC on greenhouse gas emissions.
