Solar Radiation Management: A Climate Tool with Geopolitical Implications

Date de publication
26 October 2026
Accroche

The Paris Agreement (2015) aims to keep global warming below 2 °C, preferably 1.5 °C, above pre-industrial levels. Mitigation (reducing greenhouse gas emissions) remains the core tool for reaching net carbon neutrality  by mid-century. However, a temperature overshoot is anticipated.  The United Nations Environment Programme (UNEP) forecasts that the 1.5 °C threshold will be exceeded in the coming years, with warming potentially peaking between 2.2 °C and 3.6 °C this century.  Against this backdrop, three trends characterize the climate policy debate.

Ifri, a foundation recognized as being of public utility, relies largely on private donors – companies and individuals – to guarantee its sustainability and intellectual independence. Through their funding, donors help maintain the Institute's position among the world's leading think tanks. By benefiting from an internationally recognized network and expertise, donors refine their understanding of geopolitical risk and its consequences on global politics and the economy. In 2026, Ifri partners with over 90 French and international companies and organizations.
