Intergovernmental Panel on Climate Change (IPCC): 2024 Assessment Report
Le sixième rapport d’évaluation du Groupe d’experts intergouvernemental sur l’évolution du climat (GIEC) constitue la synthèse scientifique la plus complète sur le changement climatique. Établi en collaboration avec l’Organisation Météorologique Mondiale (OMM), ce document fournit un résumé stratégique à l’intention des décideurs, soulignant l’urgence d’agir face aux défis climatiques.
The evidence is clear: the impacts of global warming are already visible in every region of the world. Emissions continue to rise, and current trends remain far from the goals set bythe Paris Agreement. But the report also emphasizes a key point: every tenth of a degree counts, and every action can make a difference.
In this article, we provide a structured summary of the IPCC’s 2024 report. The goal is to understand the key messages, identify trends, and place this data within a framework that is useful for economic and regional stakeholders.
In brief: The IPCC’s 2024 Assessment Report confirms a temperature increase of +1.1°C compared to pre-industrial levels, with a projected rise to +3°C by 2100 unless immediate action is taken. For businesses, this means accelerating efforts to assess their carbon footprint, reduce emissions, and adapt to climate change. (Updated August 5, 2026 — source: IPCC, Sixth Assessment Report)

Current State of the Climate: Alarming Findings
The latest data from the IPCC, based on national greenhouse gas inventories, show an unprecedented rise in global temperatures.
- Global warming has reached +1.1°C compared to pre-industrial levels, which calls for an immediate response and ambitious measures to mitigate climate change.
- Greenhouse gas emissions continue to rise, despite international commitments.
- This trend jeopardizesthe goal of limiting global warming to 1.5°C, as set forth inthe Paris Agreement.
Observed Impacts and Future Projections
The IPCC working group's report highlights several critical points:
- Increase in Extreme Weather Events
- Acceleration of Sea Level Rise
- Increasing Loss of Biodiversity
- Increased Risks to Global Food Security
🔴 Without immediate action, warming could reach +3°C by 2100, exceeding the safety thresholds established by the scientific community(United Nations Environment & IPCC).
Solutions Proposed by Experts
1️⃣ Reduction of greenhouse gas emissions
- Top priority: Drastically reduce emissions.
- A rapid transition to renewable energy.
- Carbon neutrality to be achieved by 2050.
📊 National inventories show that a rapid transformation of the energy sector is essential.
2️⃣ Adaptation and Resilience
The IPCC recommends strengthening the resilience of infrastructure and ecosystems, in particular by:
-
- Development of nature-based solutions
- Improving Early Warning Systems
- Strengthening International Cooperation
3️⃣ Social Dimension and Equity
The Sixth Assessment Report focuses on climate justice:
-
- The most vulnerable populations are the hardest hit, even though they are the least responsible for global warming.
- A just and equitable transition is essential to ensuring collective action.
Outlook and Recommendations
The World Meteorological Organization and the IPCC emphasize the urgency of coordinated global action :
-
- 📌 Strengthening national climate policies
- 📌 Accelerating the Development of Green Technologies
- 📌 Improvements to climate monitoring systems
- 📌 Increased support for developing countries
A clear warning sign
The IPCC's latest assessment report is a clear warning. 🚨
Technical and economic solutions exist to limit global warming, but implementing them requires strong political will andan unprecedented mobilization of all stakeholders. At the corporate level, this begins with understanding and conducting a carbon assessment (or GHG assessment), implementing concrete environmental actions, and committing to a genuine ecological transition.
Every fraction of a degree counts: the decisions we make today will shape the future of our planet.
The time for action has come. The next few years will be crucial in preventing the most serious consequences of climate change.
