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

The Net Zero Stocktake 2022 report shows that target-setting momentum continues and measures of quality are improving, but also that an alarming lack of credibility pervades the entire landscape.

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.

This working paper provides an overview of climate commitments and actions from non-state and subnational actors in the Latin America and the Caribbean region.

The two reports aim to obtain enhanced understanding of nascent but rapidly growing non-state and subnational actors’ action on GHG emissions reductions in China and India.

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...

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...

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...

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...

In this report, the Climate Action Tracker (CAT) explores several sets of scenarios for the evolution of the passenger vehicle stock in China, in order to inform on emission reduction and electricity demand implications. Summary: China is currently the global leader in battery electric vehicle (BEV) sales annually, a position it has held since 2015 when it surpassed the US. The one positive policy priority in China’s COVID-19 recovery focused on transitioning the transport sector towards development of public transport systems and electrified transport. New energy vehicles (NEVs), which...

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...

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 CO 2 emitting Parties to the UN climate convention pre-Paris Agreement (Iran, Kazakhstan, Thailand and Ukraine) and one of the largest land-use...

This scientific article in ‘Renewable and Sustainable Energy Reviews’ looks at climate change mitigation policies in five major emitting economies: China, the European Union, India, Japan and the United States. It analyses their performance in terms of energy system and greenhouse gas emissions indicators. The review centres on the sectors of electricity generation, passenger vehicles, freight transport, forestry, industry, buildings, agriculture, and oil and gas production. The article further presents an explorative emissions scenario developed under the assumption that all countries will...

This study aims to obtain enhanced understanding of subnational (e.g. cities and subnational regions) and non-state (e.g. companies) actors’ action on GHG emissions reductions in the European Union (EU). Specifically, we present an overview of findings in the recent literature on (i) landscape of sub/non-state action, (ii) interactions between EU policy making and sub/non-state actors, (iii) potential GHG emissions reductions additional to the reductions expected under national policies, and (iv) progress towards their own short- to mid-term targets and long-term goals. This report focuses on...

This difference between “where we are likely to be and where we need to be” has become known as the ‘emissions gap’.
