Greener vehicle manufacturing must be a collective goal

The Environmental Protection Agency (EPA) estimates that a typical passenger vehicle with an internal combustion engine (ICE) produces 4.6 metric tons of CO2 annually. The exact amount of carbon produced during the manufacture of a vehicle, however, is nuanced—in 2010, The Guardian reported that a basic Citroen C1 contained approximately six tonnes of CO2, while a full-spec Land Rover Discovery contained as much as 35 tonnes.
