Abstract:

An accelerated global transition to ZEVs could reduce road transport CO2 emissions 73% by 2050 compared to 2020 levels. Transitions to HD ZEVs represent approximately half of this emissions reduction potential. Achieving this level of ambition for the HDV sector would yield cumulative CO2 emission reductions of 47.5 billion tonnes between 2020 and 2050. The ZEV share of global HDV sales needs to rise to 45% by 2030, and to nearly 100% no later than 2040, if the transportation sector is to fulfil its emission reduction responsibilities in line with Paris Agreement goals. The needed pace of transition varies across individual HDV segments; greater ambition is required for segments, like buses, where zero-emission technology is commercially available and cost-effective.
