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 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...

This report analyses the momentum of targets for net-zero emissions across companies, cities and regions worldwide. We seek to unravel the ambiguity of net-zero targets to better enable the identification of truly ambitious actors and enhance support towards them. We offer recommendations for increasing target transparency with the aim of achieving greater accountability and ambition. Main Findings: 1. Net zero momentum is accelerating: The number of net-zero pledges from cities regions and companies has roughly doubled in less than a year since late 2019 As of October 2020, actors with net...

The rising importance of cities, states and regions, firms, investors, and other subnational and non-state actors in global and national responses to climate change raises a critical question: to what extent does this climate action deliver results? This article published in Climate Policy journal introduces a conceptual framework that researchers and practitioners can use as a template to assess the progress, implementation, and impact of climate action by sub- and non-state actors. Main Findings: The proposed framework is used to review existing studies that track progress, implementation...

This report presents an overview of recently adopted climate policies, climate-relevant responses to the COVID-19 pandemic and a state of play of NDC and LTS submissions in 25 countries and regions. The policy information compiled by NewClimate Institute, PBL Netherlands Environmental Assessment Agency and the International Institute for Applied Systems Analysis (IIASA) is an update of a previous report published in June 2019, and supplements the December 2019 report on the projected greenhouse gas (GHG) emissions under currently implemented policies and mitigation commitments. Main Findings...

Financial institution’s climate-related investment targets have rapidly grown in recent years. In this report, we provide insights into the magnitude and ambition of these targets, and investigate their relationship with GHG emissions in the real economy. Specifically, this report maps out the financial sector’s climate-related investment targets against a range of indicators, such as monetary investments in ‘green’ projects, and required ‘green’ investments and GHG emission reductions. It thereby considers both climate-related investment pledges made by individual financial institutions as...

A growing number of subnational and corporate actors set net-zero emissions targets. These include some of the world’s largest companies, and hundreds of cities and regions around the world. This paper provides a summary of the momentum of target setting among these subnational and corporate actors. Main Findings: The shift towards net-zero greenhouse gas emission pathways is accelerating. An increasing number of subnational and corporate actors are setting net-zero emission targets. These encompass: 823 cities and 101 regions, which represent more than 828 million people across every...

This report assesses the implications of the COVID-19 pandemic and associated recovery measures on emissions out to 2030 and global emission pathways towards meeting the Paris climate goals (‘what-if’ scenarios). Furthermore, the study reviews the most recent insights published in the literature on post-COVID emissions projections and green recovery trajectories, and provide a framework for analysing the ‘greenness’ of recovery packages, using Germany as a case study. Main Findings: This report assesses the implications of the COVID-19 pandemic and associated recovery measures on emissions out...

This article quantifies the potential greenhouse gas (GHG) emission reductions resulting from the full implementation of major international cooperative initiatives’ (ICIs) goals. We develop criteria to select the most significant ICIs to aggregate, and propose novel methodologies to quantify emission reduction impacts and account for overlaps between them. The analysis was conducted for 17 initiatives, across eight sectors and ten major emitting economies accounting for roughly two-thirds of global GHG emissions in 2019. ICIs are international activities outside the UNFCCC driven by cities...

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. The analysis was conducted for NSAs operating within ten major emitting economies that together accounted for roughly two-thirds of global GHG emissions in 2016. Our assessment includes 79 regions (e.g. subnational states and provinces), approximately 6,000 cities, and nearly 1,600 companies with a net emissions coverage of 8.1 GtCO2e/year, or a quarter of the...

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 25 major emitting countries/regions up to 2030, taking into account the emission trajectories based on current policies and the implementation of nationally determined contributions (NDCs). The report concludes that 12 out of the 25 countries and regions analysed are not on track to achieve the NDC targets they have set for themselves. This report updates the 2018 report, and...

This is the tenth edition of the United Nations Environment Programme (UNEP) Emissions Gap Report. It provides the latest assessment of scientific studies on current and estimated future greenhouse gas (GHG) emissions and compares these with the emission levels permissible for the world to progress on a least-cost pathway to achieve the 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’. NewClimate Institute staff ( Takeshi Kuramochi, Frederic Hans, Niklas Höhne, Maria Jose de Villafranca, Leonardo...

This study assesses the EU's 2050 target, i.e. halving global emissions by 2050 to be in line with 2°C, in today's setting to evaluate if the target, which was set ten years ago, is still appropriate and/or sufficient. It offers recommendations for the EU to aim for more ambitious targets. Key findings: The EU’s 2050 greenhouse gas reduction target of 80% to 95% from 1990 levels adopted 10 years ago is outdated as its basis has changed substantially. The global goal agreed in Paris in 2015 is more ambitious and pathways to that goal are now steeper not only because of the more ambitious goal...
