The French minister for Ecological Transition, Monique Barbut, has proposed raising the limit of the Livret A, a popular savings account in France, from 23,000 euros to 30,000 euros. This increase is intended to generate 10 billion euros annually, which would be used to fund climate change adaptation efforts. The proposal comes at a time when the government is reviewing all areas of the budget to ensure a balanced 2027 budget while keeping the public deficit under control. Barbut was asked to present a plan in early October to speed up adaptation efforts, as France is expected to see a temperature rise of up to +4°C by the end of the century. This proposal follows a summer that was marked by extreme weather conditions, including heatwaves, wildfires, and droughts that affected much of the country. According to Météo France, 2026 was the hottest summer on record in France and the second driest. Temperatures exceeded 40°C on 178 occasions, and on nearly 651 days, the temperature was above 35°C. These extreme conditions have already had economic consequences, with the Ministry of Economy estimating that the heatwaves this summer caused a 0.1% loss in GDP. Barbut explained that the additional funds generated by raising the Livret A limit would be used in the form of long-term subsidized loans. These loans would help hospitals install systems to manage both heat and cold, and assist local authorities in better insulating public buildings. She emphasized that the proposal is not a tax but an opportunity for French citizens to use their savings to contribute to national climate adaptation efforts. In addition to the Livret A proposal, Barbut has called on other ministers to identify specific actions to speed up the implementation of France’s national climate adaptation plan. This includes measures that can be taken across various sectors to better prepare the country for the long-term impacts of climate change. The government is under pressure to act decisively as the effects of global warming become increasingly evident in everyday life and economic performance.
