The hon. Lady neatly brings me on to the next issue that I want to address. She is absolutely right to say that there is real concern about what will happen to those vital principles as a result of the Bill. Her new clause 60 aims to address precisely that by ensuring that, after withdrawal, the environmental principles embedded in EU law are fully retained as part of UK law. I welcome the fact that the Secretary of State has a planned consultation on the principles, but I am worried about the timescale, because we need the outcome to be meaningful and to know what it is before the Bill finishes its passage through both Houses of Parliament. I hope that the Secretary of State will be in listening mode, because so many people are deeply and rightly concerned about what will happen to those principles as a result of the Bill as it stands. The environmental law that the Bill rightly sets out to transfer into UK law is composed of not only specific legal obligations such as the prohibition on certain chemicals, but a broad and comprehensive framework in which those obligations are embedded. That framework includes a number of environmental principles-including the precautionary principle, the “polluter paysâ€ principle and sustainable development-and they underpin and aid the interpretation of those legal obligations. That assists Governments, agencies and courts to understand and correctly interpret the aims and objectives of EU environmental law. Currently, those environmental principles are set out in the EU treaties, and they have been instrumental in decisions such as the EU ban on imports of hormone-fed beef, the moratorium on neonic pesticides and the control of the release of genetically modified organisms in the EU. To give just one example of how that has benefited environmental protection in the UK, the “polluter paysâ€ principle states that the polluter should bear the expense of carrying out pollution prevention and control measures. The EU's water framework directive, which drives the sustainable management of the UK's waterways, has led to enormous improvements in the quality of our drinking water and it is specifically based on the “polluter paysâ€ principle.
