This report is the third and the latest edition of the series since 2018 that take stock of climate action by cities, regions and businesses and their global aggregate impact on greenhouse gas emissions. The 2021 edition focuses on the progress of non-state and subnational actors toward their emissions reduction targets. Read More
A new tool to evaluate integrated climate action of non-state and subnational actors The world now faces a critical juncture as countries are updating their next wave of NDC climate targets. To ensure ambitious and inclusive target setting and implementation, governments must build on existing efforts to recognize and integrate the full range of non-state… Read More
The ICAT Climate Action Aggregation Tool (CAAT) is an Excel-based tool to aggregate non-state actors’ climate policy efforts. Read More
This working paper describes the landscape, (additional) GHG emission reduction potential, and progress towards target realisation of subnational and non-state actors in the EU. Read More
We seek to unravel net-zero targets to better enable the identification of truly ambitious actors and enhance support towards them. Read More
This Climate Policy journal article introduces a conceptual framework to assess the progress, implementation, and impact of climate action by sub- and non-state actors. Read More
In this Climate Week NYC event, we presented the dynamic field of non-state and subnational action, its opportunities and uncovered potential for climate ambition.

A growing number of subnational and corporate actors set net-zero emissions targets. This paper provides an summary of the momentum of target setting among these subnational and corporate actors. Read More
This article quantifies the aggregate potential of greenhouse gas (GHG) emissions reductions in 2030 from full implementation of 17 major international cooperative initiatives. Read More
This article quantifies the net aggregate impact in 2030 of commitments by individual non-state and subnational actors (e.g. regions, cities and businesses, collectively referred to as ‘NSAs’) to reduce greenhouse gas (GHG) emissions. Read More
This report is the second global analysis of local and regional government and corporate climate contributions, updating “Global Climate Action from Cities, Regions, and Companies” launched at the 2018 Global Climate Action Summit. Read More
This report is the most comprehensive assessment of non-state actor commitments to reduce greenhouse gases to date. Key results show that action by cities, states, regions and business can go a long way towards meeting the goals of the Paris Climate Agreement, but their actions alone are not enough to hold global temperature increase to well-below 2°C and work towards limiting it to 1.5° C.

Niklas Höhne presents from Paris at COP21 on the impacts of non-state and subnational action for climate change mitigation. 07 December 2015 12:00, German Pavilion, COP21
The aim of this study is to quantify the potential impact of a selected number of actions by non-state actors and partnerships on Germany’s GHG emissions. We focus chiefly on the impact of such initiatives on the 2020 emissions gap, although our analysis also extends to longer-term targets (2030 to 2050) wherever such pledges exist. Read More
