This autumn’s busy negotiation agendas, offer a window of opportunity to move the reform of the international climate finance architecture (IFA) up one level. This acceleration is urgent if we want to keep pace with the dramatic change in scale needed to finance the climate transition.  In 2023, developed countries announced that they had – for the first time since 2009 – achieved their USD 100bn/year climate finance target to support climate action in developing countries. Just two years later, this target is already obsolete, with needs for emerging and developing economies (excluding China) estimated at around USD 2.4 trillion per year by 2030. 

Directing more wood towards long-life products such as panels and insulation materials can help us maximise carbon sinks without increasing forest harvests. That’s because these products store carbon for a longer periods of time in form of long-lasting construction and renovation materials. But for this to happen in practice, more market opportunities and production capacity are needed. How can public policies help?

Assessing the economic implications of climate policies is essential for steering public action. Sig­nificant progress has been achieved in assessing the costs of mitigation, particularly with the publication in 2023 of the report on the economic implications of climate action. However, as the Cour des Comptes noted in its 2024 annual public report, numerous issues surrounding adaptation continue to emerge. Our recent work has nev­ertheless enabled us to draw five initial conclusions on the subject.
