Without an immediate and drastic reduction in greenhouse gas emissions in all sectors, it would certainly be impossible to control global warming to 1.5 ° C compared to the pre-industrial era. Keeping within the very ambitious scope of the Paris Agreement adopted in 2015 means achieving a peak in emissions after 2025, before the collapse in all areas.

The changes that need to be made are significant and include a significant reduction in fossil fuels, an increase in renewable energy, energy efficiency and electrification, lifestyle changes, a significant increase in funding and support for technological innovation. The key decisions of the Intergovernmental Panel on Climate Change (IPCC) were released on Monday, April 4, with the third and final part of its sixth assessment report scheduled for September.

With the last word, it was completed more than forty-eight hours late. A record since the creation of the United Nations in 1988.

According to observers, the closures focus on the reduction of fossil fuels, the role of technologies, equity issues and especially finance. Developed countries, led by the United States, are reluctant to point out significant financial flows that developing countries need to reduce their emissions. Saudi Arabia, for its part, sought to reduce reports of the use of fossil fuels.
