Owners of electric cars could be given free annual parking permits.

Camden Council is considering the plans which aim to encourage residents to choose vehicles with lower CO2 emissions or electric cars.

Other plans include free annual parking permits for owners of electric cars.

In contrast, owners of cars that emit more CO2 will be subject to higher charges, the council said.

Environmental impact

The proposals will be discussed by council executives in two week's time - if approved, the policy could be introduced by May.

Mike Greene, executive member for environment at Camden Council, said: "Camden Council wants to encourage residents to think about the way they get around and the impact that this has on climate change and air quality.

"To a degree we are saying 'the polluter pays', as the minority whose cars are causing greater damage to the environment will be charged more for their parking permits."
