This is a global overview of all targets announced, as of June 2021, for phasing out of the sale or registration of new internal combustion engine (ICE) passenger cars. It includes details of each goal in a concluding table. Note that the phase-outs called for in different jurisdictions vary in their timing and in their definition of what qualifies as a zero-emission, or non-ICE, vehicle. An understanding of the different vehicle technologies involved is important when considering the potential climate implications of these initiatives, and this briefing provides an overview of these technologies.
