What role should the costs of inaction play in decisions on climate change adaptation?

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.

Ten years after the adoption of the Paris Agreement, what progress has been made to make financial flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development (the ambition set out in Article 2.1(c) of the Agreement)? And what is needed going forward? Although we still lack a comprehensive assessment of progress, this article draws on existing analysis of what can help align financial flows and examines the efforts made by governments and the financial sector to this end. It highlights a development in the debate towards a country-driven approach and a focus on real investment needs. It explores ways to overcome existing barriers to action despite a challenging global context. The article advocates that Article 2.1(c) should be viewed not as a stand-alone provision, but as something that requires full implementation of all the provisions of the Paris Agreement. It also calls for a shift from a target-focused to an action-focused finance agenda and discusses how the COP30 in Belém can contribute to this.

Cette étude s’inscrit dans la continuité des travaux d’I4CE engagés depuis plusieurs années sur la qualification et la quantification des besoins et des moyens pour l’adaptation en France. Elle propose une vision d’ensemble de ce que l’on peut dire à date sur ces aspects, basée sur le suivi et l’analyse d’une quinzaine de domaines d’action publique concernés par le changement climatique. Alors que l’adaptation est souvent un grand oublié des PLF, ce rapport apporte des éléments sur l’effort consenti aujourd’hui, les besoins identifiés pour demain et les modalités de répartition des coûts.
