This webinar examines holistic approaches to designing and implementing policies and market structures that drive transitions to net-zero-emission energy systems. The session covers all elements of the energy system across power, buildings, transport, and industry. Both straightforward decarbonization solutions (e.g., transport electrification) and more challenging areas (e.g., aviation) will be addressed. Panelists discuss best practices and barriers to consider in taking a whole-system approach toward decarbonization in the energy sector.
