The COP30 Presidency Roadmap on Transitioning Away from Fossil Fuels should: (i) identify key international cooperative initiatives in the Global Climate Action Agenda that can support the development of the Roadmap and its implementation beyond COP31; (ii) use the Just Transition Work Programme’s key messages agreed at COP30 to identify differentiated options for implementation; and (iii) map systemic barriers and solutions supporting the transition, building on existing global climate action work. By so doing, the Roadmap will: (i) enable enhanced international cooperation on just energy transitions; and (ii) inform the second global stocktake on the progress made toward achieving relevant first global stocktake outcomes.
