The report examines the Swedish hybrid-electric vehicle TIS between 1990 and 2010, finding that while early efforts were driven by urban air quality and concept vehicles, later developments shifted toward fuel efficiency and CO2 reduction. It highlights the role of state-funded R&D programs in maintaining technical knowledge and the significant impact of international dynamics, such as the success of the Toyota Prius and EU emission directives, over national governance in driving commercialization.

The research evaluates climate governance across 12 intergovernmental fora, including the G7, G20, ASEAN, and AU, using a framework of five functions: Guidance and Signal, Rules to Guide Collective Action, Transparency and Accountability, Means of Implementation, and Knowledge and Learning. The analysis of 1,412 references reveals that while most fora have adopted long-term decarbonization visions and medium-term targets, the strength of these signals varies. Informal groups, particularly the G7 and G20, provide the most significant contributions. Key strengths include commitments to the Paris Agreement and joint R&D, while critical weaknesses are found in transparency and accountability mechanisms, as well as a lack of actionable policy coordination. Some signals, such as the promotion of gas as a transition fuel or the image of coal, are noted as potentially contradictory to Paris Agreement goals.
