Objectif

There are countless studies highlighting the costs already observed or expected from the sudden impacts of climate change. However, proactive measures to prepare for and adapt to these impacts remain rare and insufficiently ambitious. 

 

The aim of this conference was to open a discussion on how to take into account the assessment of the costs of inaction in terms of adaptation in collective choices and investment decisions. The aim was to bring long-term and highly aggregated assessments down to the actual timeframe of decisions (e.g., the horizon of a mandate or a medium-term strategic plan) and to pay particular attention to who bears (or will bear) what costs and who will be the beneficiaries of adaptation. We need to sharpen our focus in order to move from assessments designed to raise awareness to data that is truly useful for comparing options, identifying those who could contribute to their implementation, and building economic models for climate change adaptation policies and projects.

    On Carbon Removals and Carbon Farming the devil is in…the demand

    The implementation of carbon farming practices on European farms and in European forests is a lever for achieving carbon neutrality, but also for farm resilience, the adaptation of forest stands to climate change and for contributing to our strategic independence. Certifying and financing low-carbon practices is the objective of the CRCF (Carbon Removals and Carbon Farming) regulation, which will come into effect in 2026. Now seems the right time to draw lessons from six years of experience with a similar standard in France: the “Label Bas-Carbone” (Low Carbon Label – LBC). The results show that striking a balance between scientific rigour and accessibility for stakeholders has led to the development of a substantial range of projects. However, the real challenge is to build sufficient and appropriate demand to finance the projects. There is no miracle solution, but complementary financing channels may emerge.

    2026: An electric atmosphere

    The year ahead promises to be electric. In a highly unpredictable geopolitical context, the European Union must balance its commitment to the long-term goals of climate neutrality and the immediate attention to security and competitiveness concerns. This puts electrification high on the agenda in Brussels. First, the Grids Package, presented in December 2025, provides for a more centralised approach to planning and is expected to be adopted by the Council in June. Second, before the summer, the Commission intends to present an Electrification Action Plan, which will focus on lowering prices and reinforcing demand.

    Paris +10: France and Europe must step up on climate – to protect our security, sovereignty, competitiveness, and public finances

    How distant December 12, 2015 now seems. All delegations at COP21 had then rallied behind Laurent Fabius’s little green hammer. Ten years later, the trend is closer to backlash. Climate action is now often portrayed in the public debate as too costly, because it requires major investment. Ineffective, since our share of global emissions is small. Unfair, because it cuts into purchasing power. Too divisive, supported only by part of the electorate. Too late, since keeping the planet below +2°C of warming now seems out of reach. Arguments that are partly true—yet require substantial nuance.
