If you want to know the true impact that a car is having on the environment, simply measuring its fuel use and emissions isn't enough. You've got to look at the vehicle's entire lifecycle from the sourcing of the raw materials to build it right through to its eventual date with the car crusher.
The manufacturing process has a big role to play in a car's life cycle environmental impact and as cars get more complex, requiring more batteries and electric motors, it's only going to get bigger.
To keep things under control, car manufacturers are investing heavily in greener manufacturing processes. Modern car production facilities are designed to minimise energy consumption, often utilising solar power, while computer-controlled manufacturing systems and strict recycling regimes help to cut waste.
A number of carmakers have also become involved in outside environmental projects designed to offset the impact their activities are having on the planet.
