Transport accounts for approximately 16.9% of global GHG emissions (8.3 GtCO2 emissions in 2018) and is the fastest growing source of emissions after industry (Climate Watch 2021).

Emissions from road transportation hold the majority share, with rail, aviation, and shipping all comprising a much smaller proportion, each around 1% or less of global emissions.

Moving away from the conventional IC engines would be challenging for many developing countries due to the lack of infrastructure. But over a period of time, the cost of lithium-ion batteries have decreased and further investment by local governments and technology sharing by developed countries can help in transitioning over to battery-powered vehicles.

The map above shows ICE (internal combustion) phase-out targets in two ways: First, targets that would allow cars other than BEVs, FCEVs, and PHEVs are excluded. Second, the map differentiates between countries, states, and provinces that plan to only allow the sale or registration of new BEVs and FCEVs by a certain date and those that would also allow PHEV sales.

(Note: Countries such as Japan which pledge to include hybrid electric vehicles and mild hybrid electric vehicles are excluded as these vehicles are non plug-in hybrids)
