This article explores the reception of the IPCC reports on a national scale, focusing on the case of the
Sixth Assessment Report (AR6) in France and Switzerland. It sheds light on the orchestration
processes of national reception by the actors involved in the two science-policy interfaces, and
introduces the theoretical concept of “landing” for the comparative analysis. Using mixed qualitative
methods, it reveals that in both case studies, the domestic science-policy interactions stemming from
the landing deviated significantly from expectations. Unusual actors different from the IPCC National
Focal Points got involved in framing the conditions of the report’s domestic reception, and AR6 faced
challenges when entering national Parliament. The results are discussed within the broader context of
a global reflection on the imperative to enhance the dissemination channels of the IPCC scientific
results to political audiences.
