Is an electric car better for the environment?
Over its whole life, a battery-electric car used in the UK generally has lower greenhouse-gas emissions than a comparable petrol or diesel car. Manufacturing the car and battery still has an impact. No exhaust emissions does not mean no environmental footprint.
Look beyond the exhaust
A fair comparison includes materials, vehicle and battery manufacture, energy used while driving and what happens at the end of the car's life. The Department for Transport commissioned research on those lifecycle impacts. Vehicle size, battery size, mileage and electricity supply all affect the comparison.
Where the benefit comes from
A fully electric car has no exhaust emissions while driving. Using electricity instead of petrol or diesel can reduce lifetime greenhouse-gas emissions even after battery manufacture is counted. Tyres, roads, material extraction and manufacturing still have environmental costs.
Make a practical choice
Our view is to choose the smallest car and battery that comfortably meet your needs, with enough range for a sensible routine. Looking after it, driving efficiently and using it for longer all deserve consideration alongside the badge on the bonnet.
Do I need to replace a working car immediately?
There is no single right replacement date for everyone. Think about how much you drive, the car you have, what would replace it and how long you would keep the replacement. For journeys that work without a car, walking, cycling or public transport can reduce the need to drive at all.
