    Climate: five key debates from the French marathon budget

    Climate change and ecological planning are taking centre stage in this autumn’s budgetary measures. The public finance programming act, which has yet to be discussed with the Senate, now requires the government to set out a multi-year funding strategy for planning. The finance bill for 2024, which will go through Parliament soon, earmarks an additional €7 billion in transition support for households, businesses and local authorities. This €7 billion does not, however, resolve the issue of financing the climate transition, and in this post we provide an overview of the key climate debates that will take place, or ought to take place according to I4CE, during this veritable marathon budget.

    Can France finance the transition only with budget savings?

    How does the government plan to finance the increase in its public spending on climate action? Further to the government’s reactions to the Pisani-Ferry report, which proposes using all options, including debt and tax increases, let us make an assumption: what if the government were to rely solely on budget saving options? I4CE's Damien Demailly reviews the savings options available to the government. Clearly, they are all difficult to implement and some may prove counterproductive. They are nevertheless on the government’s agenda and are worth explaining and discussing, as are all options to finance the transition.
