Climate Change Performance Index 2024
Publication date 08 Dec 2023

The Climate Change Performance Index monitors climate mitigation progress of 63 countries and the European Union, together responsible for more than 90% of global emissions.

The Emissions Gap Report 2023
Publication date 20 Nov 2023

This is the 2023 edition of the UNEP Emissions Gap Report series, which tracks our progress in limiting global warming well below 2°C and pursuing 1.5°C in line with the Paris Agreement.

Emissions scenarios for major economies: 2023 update
Publication date 15 Nov 2023

Full implementation of existing policies and actions could result in 2030 emissions below 2019. Out of the 25 countries analysed, 13 are on track to meet their current NDCs.

Sequencing Climate Change Mitigation Targets and Policies
Publication date 01 Nov 2023

This study projected greenhouse gas emissions to evaluate the progress of 25 countries towards their original and updated NDCs. It found that almost one-quarter of the countries submitted more ambitious, updated NDCs without adopting sufficient policies to meet their original targets. Additionally, in most countries, updated NDCs lead to emissions above current policies. The findings also suggest that these patterns are influenced by national constraints, especially reliance on fossil fuels. Appropriate sequencing of ambition raising and policy adoption is urgently needed to translate the Paris Agreement into action.

Expanding climate policy adoption improves national mitigation efforts
Publication date 09 Jun 2023

Despite the collective increase of policies in force, countries can still expand climate policy to use the full breadth of mitigation options available.

Greenhouse gas distributions to inform the global stocktake
Publication date 03 Mar 2023

In this analysis, we demonstrate how global progress across a range of sectoral emission indicators can be assessed using performance distributions to allow for a detailed and nuanced analysis without singling out individual countries.

The Climate Change Performance Index 2023
Publication date 14 Nov 2022

Developed by Germanwatch, NewClimate Institute and CAN, the CCPI analyses and compares climate change mitigation efforts across 59 countries (plus EU as a whole). Together these countries account for 90 percent of global emissions. The index aims to enhance transparency in international climate politics and enable comparison of mitigation efforts and progress made by individual countries.

Emissions scenarios for major economies: 2022 update
Publication date 10 Oct 2022

Few countries improved their NDCs since 2021 Glasgow call to update targets. Out of the 25 countries analysed, 11 are on track and 14 are off track to meet their current NDCs. Iran and Türkiye are yet to submit updated NDC targets.

G20 emission projections to 2030 improved slightly since the Paris Agreement
Publication date 15 Jul 2022

Research shows the emission projections to 2030 for the G20 improved slightly but remain insufficient to meet Paris Agreement temperature goals.

Updated NDCs collectively raise ambition levels but need strengthening
Publication date 21 Jun 2022

This journal article shows that updated nationally determined contributions (NDCs) collectively raise ambition levels but need strengthening further to keep Paris goals within reach.

Introducing performance distributions to visualise collective progress towards mitigation goals of the Paris Agreement
Publication date 09 Jun 2022

Visualising country progress as performance distributions fulfils the GST’s criteria of evaluating collective progress while communicating that not all countries are the same.

Unpacking the COVID-19 rescue and recovery spending: an assessment of implications on greenhouse gas emissions towards 2030 for key emitters
Publication date 11 Mar 2022

We developed a new framework to categorise rescue and recovery spending measures according to their level of greenness and their type of expected impact on greenhouse gas emissions.

The Climate Change Performance Index 2022
Publication date 09 Nov 2021

Developed by Germanwatch , NewClimate Institute and CAN , the CCPI analyses and compares climate change mitigation efforts across 60 countries (plus EU as a whole) with the highest emissions. Together these countries account for 90 percent of global emissions. The index aims to enhance transparency in international climate politics and enable comparison of mitigation efforts and progress made by individual countries. Race Towards Climate Neutrality Is Underway: CCPI’s top countries lead the way Scandinavian countries, together with the United Kingdom and Morocco, lead the ‘race to zero’...

A seismograph for measuring the transformation to net-zero greenhouse gas emissions – Discussion Paper
Publication date 03 Nov 2021

A “transformation seismograph” can give an early warning signal with small perturbations at the beginning, later some elements of the system start shaking, later strong vibrations occur in all areas of the system until tipping or transformation point (point of no return) is reached. In this discussion paper we explores this concept to detect and measure the transformation to net-zero greenhouse gas emissions. Abstract: This discussion paper sketches the idea of a “transformation seismograph” to detect the signs and measure the speed and magnitude of transformation to net-zero greenhouse gas...

Twenty years of climate policy: G20 coverage and gaps
Publication date 02 Nov 2021

In this Climate Policy publication, we show that the number and coverage of climate change mitigation policies have increased in the past twenty years, but important policy adoption gaps remain. Despite this increase, slow progress towards reducing global emissions and meeting the collective Paris climate goals calls for more comprehensive climate change mitigation policies. Filling policy adoption gaps presents a concrete strategy to improve sectoral, national and global climate policy. Main findings: The number and coverage of climate change mitigation policies have increased in the past...
