In “Net Zero by 2050: A Roadmap for the Global Energy Sector,” IEA stated that net zero by 2050 requires “nothing short of a total transformation of the energy system that underpins our economies,” and “the pathway is narrow but achievable.” The last 24 months has seen a groundswell of net-zero commitments by countries emitting over 90% of GHG. Corporate strategies increasingly recognize the net-zero goal. Meanwhile, after the 2020 pandemic-induced drop, global GHG concentrations increase and annual emissions rise. Net zero by OECD countries and major companies is necessary but insufficient. Can the global economy grow while emissions decline? In order to achieve net zero targets, emissions need to decline within this decade in emerging economies. Is this feasible? Can decarbonization accelerate in the power sector? When can power sector GHG emissions approach zero in OECD and in developing countries? Oil has been the major transportation fuel; transport sector emissions continue to increase. How far can the transport sector be electrified?
