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. The 2018 report established the strong potential of subnational and non-state actors to help avoid climate change. This year, we aim to inform the September 2019 UN Climate Action Summit on how mitigation by cities, regions and companies could help national governments boost their ambition beyond their current targets, to come in line with the Paris Agreement’s...

This document presents an overview of climate and energy policies mostly adopted between July 2018 and May 2019 in 25 countries and regions. The policy information compiled by NewClimate Institute, PBL and IIASA in this document supplements the December 2018 report on the projected greenhouse gas (GHG) emissions under currently implemented policies and mitigation commitments (Kuramochi et al., 2018). Key findings: This document provides an overview of about 50 policies that were adopted or under development between July 2018 and May 2019 in 25 selected countries and that may have significant...

Diese Kurzanalyse erarbeitet mögliche Pfade, die Deutschland anstreben sollte, um mit den Zielen des Pariser Abkommens kompatibel zu sein, und setzt diese in ein Verhältnis zu den derzeitigen nationalen Minderungszielen. Zusammenfassung Das 2015 verabschiedete Klimaschutzabkommen von Paris hat das Ziel, den globalen Temperaturanstieg auf deutlich unter 2°C, wenn möglich auf 1,5°C zu begrenzen und dazu die globalen Treibhausgasemissionen in der zweiten Hälfte des Jahrhunderts auf netto null zu senken. Diese Formulierung geht weit über die vorherigen internationalen politischen Vereinbarungen...

This short analysis develops possible pathways that Germany should pursue to be compatible with the Paris Agreement, and compares those pathways to current national mitigation goals. Note: The document is written in German, but contains an English summary. Summary The Paris Agreement on Climate Change signed in 2015 aims to limit global temperature rise well below 2°C, to pursue efforts to limit it to 1.5°C and to reach global net zero greenhouse gas (GHG) emissions in the second half of the century. This wording goes a long way from previous international political agreements. Countries’...

In this policy brief, the Natural Resources Defense Council (NRDC) and NewClimate Institute assess 24 practical and realistic actions to implement between now and 2030 as key elements to cut greenhouse (GHG) emissions significantly by 2030. They include such actions as deploying more renewable energy, transitioning away from coal, boosting energy efficiency, accelerating electric vehicle deployment, and ending deforestation. Main findings: The world can get on a 2℃ pathway by 2030 with “On Track” and “Scale Up” actions The implementation of just 19 of these actions can put the world on track...

Non-state and subnational climate actors have become central to global climate change governance. Quantitatively assessing climate mitigation undertaken by these entities is critical to understand the credibility of this trend. In this Perspective, we make recommendations regarding five main areas of research and methodological development related to evaluating nonstate and subnational climate actions: defining clear boundaries and terminology; use of common methodologies to aggregate and assess non-state and subnational contributions; systematically dealing with issues of overlap; estimating...

This study compares projected GHG emissions in the G20 economies under current climate policies to those under the GHG targets outlined in the nationally determined contributions (NDCs). It is based on an assessment of official governmental estimates and independent national and global studies. Findings: Highlights: Almost all G20 members are making progress in implementing climate policies. Eight G20 members are on track to meet their unconditional NDC targets. The other G20 members require enhanced policies to achieve their NDC targets. For many G20 members emissions continue to increase...

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 16 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 2017 report...

This is the 9th edition of the UN Environment Emissions Gap Report. It assesses the latest scientific studies on current and estimated future greenhouse gas 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” is known as the ‘emissions gap’. As in previous years, the report explores some of the most important options available for countries to bridge the gap. NewClimate Institute staff ( Frederic Hans, Niklas...

Since the Paris Climate Agreement solidified an “all hands on deck” approach to climate change, cities, regions and businesses have become key contributors to mitigation, adaptation and finance efforts. These actors are pledging a range of actions, from directly reducing their own greenhouse gas emissions footprints, to building capacity for climate adaptation and resilience to providing private finance. This report is the most comprehensive assessment of these non-state actor commitments to reduce greenhouse gases to date. The report focuses on 9 high-emitting countries – Brazil, China, India...

This article shows how a strengthening of existing plans by a global roll-out of successful, regional sector policies can ease the implementation challenge of reaching the Paris climate goals. The novel element of it is to integrate such detailed policy packages until 2030 into pathways that reach long-term targets until 2100 using an integrated assessment modelling framework. The study is only a first step in connecting the analysis of mitigation pathways towards the Paris climate goals with an assessment of the implementability of near to medium term (2020–2050) climate action that would be...

This article shows the potential impact on global GHG emissions in 2030, if all countries were to implement sectoral climate policies similar to successful examples already implemented elsewhere. This assessment was represented in the IMAGE and GLOBIOM/G4M models by replicating the impact of successful national policies at the sector level in all world regions. The first step was to select successful policies in nine policy areas. In the second step, the impact on the energy and land-use systems or GHG emissions was identified and translated into model parameters, assuming that it would be...

This project analyses best practice policies across Europe and how far extending them to all EU member states could support EU Greenhouse Gases (GHG) and energy targets. Key messages: The study finds that the EU can go much further than its current commitments in terms of GHG reductions: it has the potential to reach -55% to -62% below 1990 by 2030, consistent with the Paris commitment of staying “well below 2°C, pursuing 1.5°C”. The key to realize these reductions is to apply EU-wide the best practice policies identified in various Member States including The Netherlands, Denmark, UK, Germany...

NewClimate Institute, PBL Netherlands Environmental Assessment Agency and IIASA present an overview of on climate and energy policies in 25 major emitting countries and regions that have been adopted since July 2017. The policy information compiled by in this document supplements the earlier 2017 update report on the projected greenhouse gas emissions under currently implemented policies and mitigation commitments in 25 countries and regions. Not only the qualitative descriptions of policies but also their possible implications on greenhouse gas (GHG) emissions projections in 2030 are provided...

This article identifies and quantifies the 10 most important benchmarks for climate action to be taken by 2020 – 2025 to keep the window open for a 1.5°C-consistent GHG emission pathway. Abstract We conducted a comprehensive review of existing emissions scenarios, scanned all sectors and the respective necessary transitions, and distilled the most important short-term benchmarks for action in line with the long-term perspective of the required global low-carbon transition. Owing to the limited carbon budget, combined with the inertia of existing systems, global energy economic models find only...
