Sir: As Conservatives we are clear that the European Union has been central to improving the quality of the UK’s environment. European policy is not always perfect, but on environmental issues it has allowed us to move forward in leaps and bounds.

The wealth of the environment on which our economy depends is not confined to national boundaries, which is why the EU has become such a vital forum for negotiating Britain’s interest in maintaining healthy seas, clean air, climate security and species protection.
