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.

State of Climate Action 2023
Publication date 14 Nov 2023

The State of Climate Action 2023 provides the world’s most comprehensive roadmap of how to close the gap in climate action across sectors to limit global warming to 1.5°C. It finds that recent progress toward 1.5°C-aligned targets isn’t happening at the pace and scale necessary and highlights where action must urgently accelerate this decade to reduce greenhouse gas emissions, scale up carbon removal and increase climate finance.

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.

The role of green hydrogen in a just, Paris-compatible transition
Publication date 01 Nov 2023

Green hydrogen is experiencing a strong push from different directions. This report lays out principles for a sustainable approach to expanding the production and use of the energy carrier, in line with sustainable development goals and the Paris Agreement. Case studies on Colombia, India and Namibia accompany the report to highlight opportunities and obstacles.

The corporate climate accountability loop
Publication date 20 Sep 2023

This paper introduces seven key functions of an accountability system for corporate climate action. We further provide selected observations on how to improve the accountability system’s status quo.

Climate Action Tracker Briefing: Pulling the Plug on Fossils in Power

In this briefing, we present 1.5°C benchmarks for 16 countries - Australia, Brazil, Chile, China, EU27, Germany, India, Indonesia, Japan, Mexico, Morocco, Türkiye, South Africa, United Arab Emirates, the UK, and the US – and assess whether they are on track to meet them.

From Rhetoric to Reality: Investigating Financial Institutions' Net Zero Portfolio Commitments
Publication date 18 Sep 2023

Financial institutions increasingly commit to net zero portfolio targets. Our analysis questions their internal climate value and their real-world impact. Instead, we recommend that financial institutions focus on supporting the transition of economies and economic actors.

Transformative mitigation actions as an outcome of the Global Stocktake
Publication date 18 Sep 2023

The Global Stocktake under the Paris Agreement offers an opportunity to formulate specific messages for increasing climate change mitigation to inform Parties in updating and enhancing their actions.

From drumbeating to marching: Assessing non-state and subnational climate action using data
Publication date 16 Sep 2023

The 2015 Paris Agreement emphasized non-state actors (NSAs) in climate action, but ‘‘greenwashing’’ concerns persist. The UN introduced a framework for NSA accountability through improved reporting. Yet, data remains inconsistent, especially in the Global South. We propose refining reporting, broadening data collection, and using innovative tech like AI for better tracking and accountability.

Assessment of the G20 members’ long-term strategies
Publication date 24 Aug 2023

This report assesses the G20 members’ long-term low greenhouse gas emission development strategies (LTS) to identify commonalities, opportunities for international cooperation, and gaps that can be addressed in future LTS submissions.

Kein Fortschritt: Klimaschutzpolitik im deutschen Verkehrssektor entspricht weiterhin etwa 3°C globaler Erwärmung​
Publication date 23 Aug 2023

Diese Studie zeigt auf Basis der aktuellen Emissionsprojektionen aus dem August 2023, dass die Bundesregierung ihre Zusage zur Einhaltung der 1,5°C-Grenze und des Pariser Abkommens bricht. Insbesondere der Verkehrssektor verzeichnet massiv überhöhte Treibhausgasemissionen und befindet sich derzeit auf einem Pfad zu 2,8°C globaler Erderhitzung.
