Something that people don’t often think about is the energy it takes to produce a car.
Quick manufacturing emissions summary*:
6 tonnes CO2e: Citroen C1, basic spec
17 tonnes CO2e: Ford Mondeo, medium spec
35 tonnes CO2e: Land Rover Discovery, top of the range
If I drive 10,000 miles a year in my Volkswagen Up!, it’ll produce about 1800 kg of CO2**. This means my car can probably be manufactured and driven for 10 years for less CO2 than just producing the Land Rover.
(For comparison, manufacturing a bicycle produces about 250Kg of CO2 emissions.)
