Multilateralism remains vital to address the challenge of climate change, but the UNFCCC Sessions are increasingly ill-suited to the new role urgently required of the global climate governance system: to accelerate implementation, foster cooperation, overcome practical barriers, and mobilise diverse national actors to deliver transformative climate action. This paper identifies four challenges that constrain the process and proposes solutions to improve efficiency and ensure the UNFCCC Sessions are fit for purpose, namely improve agendas, organise work better, focus on implementation, and make structural changes.
