On November 12, 2022, Suzi Kerr, Chief Economist and Mandy Rambharos, Vice President of Global Climate Cooperation at the Environmental Defense Fund, participated in an IETA BusinessHUB Pavilion event at #COP27 in Sharm El-Sheikh, Egypt, exploring new models for international climate collaboration to accelerate decarbonization including #ClimateActionTeams and the South Africa Just Energy Transition Investment Plan. This event explored how different models of large-scale crediting mechanisms can support economy-wide transformation and decarbonization, support greater climate ambition beyond countries’ nationally determined contributions (NDC), and offer co-benefits for communities and ecosystems. Featuring remarks from experts working on a range of transformational-scale models, this event examined the LEAF project; jurisdictional approaches to electricity system transformation, as exemplified by South Africa; and the Climate Action Team (CAT) model.
