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...

Tracking climate mitigation efforts in 30 major emitters
Publication date 02 Nov 2021

This report by NewClimate Institute, International Institute for Applied Systems Analysis (IIASA) and FTSE Russell tracks climate mitigation efforts in 30 countries and regions. Our analysis shows that emissions trends remain far from the goals of the Paris Agreement in the period post-2020. Emissions in the 30 economies as a group are projected to increase on average by approximately 0.4% per year between 2021 and 2030. However, almost two thirds of the countries analysed will accelerate their efforts in the 2020s. Sectors remain a key entry point to accelerate emissions reductions in the...

The Emissions Gap Report 2021
Publication date 26 Oct 2021

This is the twelfth edition of the United Nations Environment Programme (UNEP) Emissions Gap Report. It assesses the gap between estimated future global greenhouse gas (GHG) emissions if countries implement their climate mitigation pledges and the global emission levels from least-cost pathways that are aligned with achieving the temperature goals of the Paris Agreement. This difference between “where we are likely to be and where we need to be” has become known as the ‘emissions gap’. The report also examines further areas that are highly relevant for bridging the gap: updated NDCs and Net...

Greenhouse gas mitigation scenarios for major emitting countries – Analysis of current climate policies and mitigation commitments: 2021 Update
Publication date 07 Oct 2021

This report by NewClimate Institute, PBL Netherlands Environmental Assessment Agency and the International Institute for Applied Systems Analysis (IIASA) provides an overview of projected greenhouse gas (GHG) emissions in 26 major emitting countries and regions up to 2030 under currently implemented policies. The report shows that emissions are projected to remain above 2005 levels in most countries but concludes that 16 out of the 26 countries and regions analysed are on track or close to achieve the NDC targets they have previously set for themselves. Eight are on track to also meet their...

Climate Action Tracker Global update: Climate target updates slow as science ramps up need for action
Publication date 15 Sep 2021

In these briefings, the Climate Action Tracker (CAT) introduces its new rating methodology, which now rates more elements than before – mitigation targets in Nationally Determined Contributions (NDCs), policies and action, and climate finance. We’ve also added a methodology for assessing net zero targets. These briefings provides an overview of the development in climate action over the last year and illustrates the new CAT assessment of the countries we analyse, based on our updated method. Summary Code red: The new IPCC report on climate science has reinforced the absolute urgency of closing...

Global climate action from cities, regions and businesses - 2021
Publication date 23 Jun 2021

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. Main findings: In this report, we focus on subnational and non-state action in ten major emitting economies: Brazil, Canada, China, the European Union (EU-27) plus the United Kingdom (UK), India, Indonesia, Japan, Mexico, South Africa, and the United States (US). We find that...

Greenhouse gas emission scenarios in nine key non-G20 countries: An assessment of progress toward 2030 climate targets
Publication date 01 Jun 2021

This study published in the "Environmental Science & Policy" journal assesses if nine key non-G20 countries meet 2030 GHG targets with existing policies. Main Findings: This study compares greenhouse gas (GHG) emissions projections in 2030 under current policies and those under 2030 mitigation targets for nine key non-G20 countries, that collectively account for about 5 % of global total emissions today. These include the four largest non-G20 fossil CO2 emitting Parties to the UN climate convention pre-Paris Agreement (Iran, Kazakhstan, Thailand and Ukraine) and one of the largest land-use GHG...

Decreasing costs of renewables in Argentina (two reports)
Publication date 17 Dec 2020

Recent analyses developed by Fraunhofer ISI and NewClimate Institute show that faster and steeper than expected cost reductions for certain key mitigation technologies over the past five years can lead to an increased technology uptake and to a higher level of climate ambition, if the initially intended investment sum is maintained. The here presented technical assessment builds on the previously developed methodology to estimate the potential impact of investment cost reductions for renewable energy technologies (solar photovoltaics (PV) and onshore wind) on Argentina’s climate targets in the...

The Emissions Gap Report 2020
Publication date 09 Dec 2020

This is the eleventh edition of the United Nations Environment Programme (UNEP) Emissions Gap Report. It assesses the gap between estimated future global greenhouse gas (GHG) emissions if countries implement their climate mitigation pledges and the global emission levels from least-cost pathways that are aligned with achieving the temperature goals of the Paris Agreement. This difference between “where we are likely to be and where we need to be” has become known as the ‘emissions gap’. The report also examines two areas that are highly relevant for bridging the gap and which have become even...
