A Paris Climate & Nature Week with a touch of ‘green budget’

31 October 2025 - Foreword of the week - By : Benoît LEGUET

We were proud to contribute to the inaugural Paris Climate & Nature Week hosted by Sciences Po from 27 to 29 October, marking the 10 years of the Paris Agreement. I4CE weighed in on some of our core topics– lessons learnt over the past decade of climate action which can accelerate the  transition; the links between climate and development finance; as well as adaptation and the cost of inaction.

 

We also announced the Julie Evain Prize for young professionals engaged in the transformation of the financial sector in memory of our colleague, her work and her dedication. More details will follow in spring 2026, with the first prize to be awarded next autumn during the next Paris Climate & Nature Week, under the patronage of Pierre Ducret.   

 

The French government couldn’t have picked a better moment than this week of reflection on climate action to release both the “green budget” tied to the 2026 draft finance bill and the second multi-year strategy for financing the transition. These two documents are cornerstones in the assessment of current funding for the climate transition and the estimate of public investment needs going forward. They usefully complement the draft budget, adding clarity and context to the fiscal debate. We will come back to this before the end of the year.

 

There is, however, still no news on the third Multi-Year Energy Programme (PPE), even though everything appears ready for signature. Interested readers may wish to read again our column in Les Échos, published in September, with an analysis that remains highly relevant. There is also no news on the sixth phase of the Energy Savings Certificates (CEE) scheme, which remains one of the pillars which the government counts on to finance the transition in a tight budget context. More on this… in due course.

    Maintaining the 2035 target: Ensuring a viable future for Europe’s automotive industry

    In the run up to the publication of the European Commission’s proposals for an automotive package on 10 December, car manufactures have stepped up the calls to relax the CO2 standards and the 2035 phase-out of new combustion-engine vehicles by including some flexibilities. They highlight the challenges the industry has faced in recent years, growing competitive pressure from China, and insufficient demand for electric vehicles in Europe as reasons for the sector needing more time for the transition required to meet the targets.

    Maintaining the 2035 target to support the transition of the French automobile industry

    With the aim to reduce its CO2 emissions and costly fossil-fuel imports, in 2022 the European Parliament adopted a rule that, from 2035, all new vehicles must be zero-emission, which essentially means that they must be electric. However, this rule is now being questioned, with car manufacturers requesting that it be revised to allow plug-in […]
