In Europe, 21% of greenhouse gas emissions are due to transport, and road transport accounts for more than 70% of them. Cars have the largest share, accounting for about 12% of total CO2 emissions in the EU. In order to achieve the goal of the European Climate Pact, namely to make Europe climate-neutral by 2050, CO2 emissions from transport must be reduced by 90%. The EC is proposing a ban on the sale of new cars with internal combustion engines after 2035, and 63% of European citizens support a ban on the sale of new diesel and petrol cars after 2030.
