UK Sustainable Car Directory


If a UK driver would like to minimise the impact on the environment from their driving, there is now an ever-growing choice of options from car manufacturers. So, if a journey is essential and cannot realistically be completed by public transport, with a considered driving style, drivers can minimise their tailpipe emissions. 

The main table below captures the main contenders available now, which have CO2 emissions at 75 g/km, or less.  To incentivise uptake, the Government has several regulations - Vehicle Excise Duty (VED), and Plug-in Grants.

Vehicle Excise Duty

For a long time now, Vehicle Excise Duty (or 'car tax', as it's colloquially known) has been tapered based on carbon dioxide emissions.  From April 2017, this is changing, such that only zero-emission vehicles will avoid the standard annual rate.  This may incentivise manufacturers to produce electric-powered vehicles in the medium-term, but means customers lose the incentivise to buy cars with very low emissions (but more than zero).  Here are the rates for cars up to 75g/km of CO2:


Emissions (g/CO2/km) First year rate Standard rate*
0 £0 £0
1-50 £10 £140
51-75 £25 £140

* An additional £310 per year is payable for the first five years, if a car costs more than £40,000.

N.B. These rates do not take account of any additional incentives which may be introduced to move away from diesel, now more widely appreciated as a cause of health problems in urban areas.

More details available here.

Plug-in Grants
The Government is currently offering plug-in grants of up to £4,500 for purchases of new vehicles which meet the following eligibility:

CategoryCO2 emissionsZero emission rangeGrantMaximum grant
1 Under 50g/km At least 70 miles 35% of cost £4,500
2 Under 50g/km 10 to 69 miles 35% of cost £2,500
3 50 to 75g/km At least 20 miles 35% of cost £2,500
