About the project

CAMDA is a community of data and analytical experts, dedicated to providing credible climate action information from regions, cities, businesses, investors and civil society. It was initiated in 2017 by a call from Patricia Espinosa, Executive Secretary UN Climate Change, and Christiana Figueres, former Executive Secretary UN Climate Change, for a collaborative network of professionals and organizations to assess and communicate the impact of climate action and to record and track ambition and progress made by these actors in the context of the Paris Agreement. The research consortium led by NewClimate Institute has comprised an integral part of the CAMDA Climate Action Tracking Initiative.  

Since 2018, the consortium has released a series of “global aggregation” reports at key climate summits and policy fora.

For example, the consortium released its 2019 Global Aggregation Update Report at the UN Secretary-General’s Climate Summit in September 2019. The report showed that sub/non-state climate action could play a crucial role in limiting global warming to 2°C or lower, if these actions were fully implemented. The report also made significant direct knowledge contributions to the United Nations Framework Convention on Climate Change (UNFCCC) process and became the basis for Clause 29 in the COP25 decision, which requested the UNFCCC secretariat to “continue engaging with non-Party stakeholders and enhancing the effectiveness of the Non-State Actor Zone for Climate Action platform, including the tracking of voluntary action”.

The ongoing three-year project phase (2021-2024) funded by IKEA Foundation (grant no. 2010-01689) aims to further advance the understanding of the universe of global subnational and non-state climate action, the potential impact of these actors on global greenhouse gas (GHG) emissions and their actual progress. This project consortium is one of the few in the world that regularly updates the global overview and assessment of climate actions by cities, regions and businesses.

Topic-wise this project will also address some of the main knowledge gaps identified in previous work:

1) Aggregation of emission reduction targets: A wealth of cities regions and businesses set themselves climate targets. We analyse if these targets in aggregate (globally and for selected countries) add ambition over what national governments are doing and planning. The ‘ambition loop’ between actors can work only if there are some cities, regions and businesses that aim for higher ambition than the national governments.

2) Tracking implementation: Targets and goals without effort to implement them are a pie in the sky. It is of utmost importance to assess measures implemented by sub/non-state actors towards their self-set targets as well as the long-term temperature limit of the Paris Agreement. We will assess the stringency of the implemented measures and whether the implemented measures are the most needed or appropriate ones.

3) Supply chain emission targets and net zero emission targets: Both are essential to limit warming below 1.5°C. It is encouraging that they have become increasingly popular among sub/non-state actors in the past years, but they can result in “greenwashing” and even lead to increased emissions if not set right. It is necessary that these emerging targets are scrutinised, so that they are set up in a way that leads to 1.5 °C-consistent emissions reductions. In this project, we conduct in-depth analyses of the climate action plans in hard-to-abate industries and sectors with significant value chain emissions.

4) Financial institutions’ climate action: Institutional investors and asset managers are such powerful non-state actors that infrastructural transformation necessary for the 1.5°C goal cannot be realised without their actions. The number of climate targets among them are rapidly increasing, but there is limited understanding on how their actions could lead to GHG emissions reductions on the ground. Without analysing the real-world impact of these targets, we cannot say if the financial sector has embarked on the transition or if it needs to be further incentivised to do so.
