Intergovernmental Panel on Climate Change (IPCC)

The Heinrich Böll Foundation is following the work of the IPCC, currently in the 7th Assessment Cycle, particularly with regard to the topics of net-zero, “overshoot” of 1.5 degrees, and high-risk geoengineering technologies such as solar geoengineering (SRM) and technological CO2 removal (Carbon Dioxide Removal, CDR).

7th Assessment Report

Climate Justice and Equitable Futures

E-Paper

The briefing shows how the scenarios of the IPCC’s 6th Assessment Report (AR6) perpetuate existing inequalities into the future. It explores alternative perspectives that prioritize equitable futures, climate justice, and well-being for all in IPCC AR7.

IPCC Open letter: CDR and CCUS Methdology Report

Open letter

Civil society open letter to the IPCC raising concerns around the planned Methodology Report on Carbon Dioxide Removal (CDR) and Carbon Capture Use & Storage (CCUS) and how it may legitimise unproven technologies and overreliance on CDR and CCUS.

Climate Justice and Equitable Futures

Recording from February 14, 2025.

The webinar unpacks the policy brief „Climate Justice and Equitable Futures: What Is Missing in IPCC AR6 Scenarios and How to Go Beyond“ with the two authors of the briefing, Tejal Kanitkar and Prof. T. Jayaraman. Hosted by Heinrich Boell Foundation and Third World Network.

6th Assessment Report

Lost in Translation: Lessons from the IPCC’s 6th Assessment Report

Analysis

On 20 March, the Intergovernmental Panel on Climate Change (IPCC) will present its Synthesis Report to its 6th Assessment Report. Our briefing highlights essential points of the underlying reports that will be crucial to creating a just and sustainable future in climate change.

IPCC Unsummarized - Unmasking Clear Warnings on Overshoot, Techno-fixes, and the Urgency of Climate Justice

Analysis

Our analysis of the latest report on climate change mitigation by the Intergovernmental Panel on Climate Change (IPCC) shows that while it warns of the negative consequences of relying on risk technologies if we overshoot 1.5°C, this is downplayed at the same time in favour of fossil fuels.

High-risk geoengineering technologies won’t reverse climate breakdown

Commentary

Techno fixes like carbon dioxide removal and solar radiation management are no substitute for exiting coal, oil and gas – whatever polluters would like you to think.

Beyond The Limits: How Gambling on Overshoot is Pushing the Planet Past a Point of No Return

Analysis

The new IPCC Working Group II Report Highlights How Gambling on Overshoot is Pushing the Planet Past a Point of No Return.

IPCC Special Report on 1.5: Limiting global warming without temperature "overshoot"

Analysis

The IPCC Special Report on 1.5 opts for a rigorous interpretation of the 1.5 limit on global warming. It has good reasons to do so: "Overshooting" that target risks irreversible impacts and damage for societies and ecosystems, and increases reliance on unproven, high-risk geoengineering technologies.

Economic Growth in mitigation scenarios: A blind spot in climate science

E-Paper

Climate change mitigation scenarios are important instruments for developing pathways towards a climate-friendly world. This short study shows that neither the use of CDR technologies is as indispensable as shown in the scenarios, nor is an overshoot unavoidable.

Societal Transformation Scenario

A Societal Transformation Scenario for Staying Below 1.5°C

Study

The Societal Transfomation Scenario is a global 1.5°C mitigation scenario that challenges the notion of continued global economic growth and its compatibility with ambitious climate targets such as the 1.5°C limit. This summary brings together all the key points.

A Societal Transformation Scenario for Staying Below 1.5°C

The „Societal Transfomation Scenario“ is a global 1.5°C mitigation scenario, which challenges the notion of perpetual global economic growth and its compatibility with ambitious climate goals like the 1.5°C limit. It shows how through a reduction of production and consumption in the Global North, we can stay below 1.5°C without resorting to high-risk technologies like CCS, geoengineering and nuclear, while also avoiding temperature overshoot.
