Amendment 57, which would leave out clause 4, is linked to new clauses 19 and 21. Many of the amendments I tabled in Committee have been proposed by Greener UK, a coalition of many environmental organisations that are concerned about the possible impact of Brexit on environmental protections. They see it as one of the biggest threats: I know other people see it as an opportunity, especially when it comes to rejigging how we subsidise agriculture once we leave the common agricultural policy. The concern is what protections would remain, given the importance of our membership of the EU for everything from cleaning up water pollution and protecting biodiversity to improving recycling and reducing waste. It is hard to believe that we used to allow untreated sewage to flow into our seas before the EU's bathing water directive forced the UK Government to make our bathing waters fit for swimming and to test for bacteria such as E. coli. In 1990, only 27% of our bathing waters met minimum mandatory standards; by 2014, 99% complied. When the then Secretary of State for Environment, Food and Rural Affairs gave evidence to the Environmental Audit Committee's inquiry on the natural environment after the EU referendum, she told the Committee that approximately a third of the more than 800 pieces of EU environmental legislation will be difficult to transpose into UK law. The Committee also identified a considerable governance gap, which the Government have acknowledged, and I support new clause 18, which would enshrine what the Government have said they want in relation to carrying over environmental principles and establishing a new environmental regulatory body. My amendment addresses the substantial flaws, gaps and democratic deficit in the Bill that were not addressed in Committee, in particular to fully transpose current EU environmental legislation in all areas effectively into UK law to avoid any weakening or loss of existing environmental protection during Brexit. The Secretary of State for Environment, Food and Rural Affairs has been encouraging in saying that:“We must not only maintain but enhance environmental standards as we leave the EU. And that means making sure we secure the environmental gains we have made while in the EU even as we use our new independence to aim even higherâ€. Opposition Members share the same aspirations and visions, but we cannot just take his word for it. We need those promises written into the Bill and concrete measures to deliver on those aspirations. This has to last longer than he is in post. Amendment 57 would leave out clause 4, with a view to replacing it with new clause 19 which would preserve-more comprehensively than clause 4-rights, powers, liabilities, obligations, restrictions, remedies and procedures derived from EU law. The new clause seeks only to properly realise the Government's stated ambition for the Bill-they have repeatedly assured us of this during the process-that the same rules and laws will apply after we leave the EU as before. In their White Paper, the Government sought to reassure us that this Bill will mean that“the whole body of existing EU environmental law continues to have effect in UK lawâ€. The Prime Minister has promised:“The same rules and laws will apply on the day after exit as on the day beforeâ€, but that is simply not the case. As drafted, the Bill will not properly capture and convert all EU environmental law into stand-alone domestic law. Clause 4 appears to deal with full transposition. In Committee, the then Minister of State for Courts and Justice described it as a sweeper provision that“picks up the other obligations, rights and remedies that would currently have the force of UK law under section 2 of the European Communities Act 1972.â€- But it fails to do its sweeping properly, because some inexplicable and unnecessary restrictions in clause 4(l)(b) and (2)(b) mean that important aspects of environmental law will be lost. Those exceptions include rights that have not been recognised by a court before exit day. Effectively, the basic rights that everyone accepts but that have not been litigated on are at risk. Those rights have been hardwired into EU law and do not need enforcing, but once we no longer have the safety net of the EU, they could fall. The Government's defence of the limitations in these subsections in Committee was far from convincing. The Minister essentially argued that they were necessary because directives do not produce directly effective rights until they have been recognised as such by courts. However, if a provision in legislation creates directly effective law, it does not need a court to confirm that that is the case. If a piece of legislation creates a legal position, it does not need a judge to verify that that is the case. In fact, the Government have often not transposed certain provisions of directives on the basis that they function adequately directly from the directives without any need to transpose them into national law. That clearly demonstrates that there are parts of directives that currently form part of UK law that will be removed by subsection (2)(b). Clause 4 does not adequately engage with failures to properly transpose EU law. An obligation should be placed on the Government to remedy incorrect and incomplete transposition. The powers to do so are contained in clause 7(2)(f), but there is a significant difference between a power to do something and a duty to use that power. To summarise, amendment 57, in getting rid of clause 4 and replacing the linked new clause 19, seeks to rectify those errors. New clause 19 is simpler and more comprehensive than the existing clause 4. It would ensure that rights arising under EU directives are preserved and that a mechanism is in place after exit day to deal with problems arising from the incomplete or incorrect transposition of EU law before exit day. If clause 4 is not amended, we could lose vital EU law provisions, including requirements to review and report on the adequacy and implementation of laws that are crucial to ensure the law is complied with and up to date. That includes the requirements contained in article 20 of the marine strategy framework directive, article 17 of the habitats directive and article 32 of the air quality directive. Without reported data under the latter, Client Earth would not have been able to hold the Government to account through the courts on air pollution. We will also lose obligations on the Government to report and send information to the European Commission, which is then able to aggregate it and use it for considering the appropriateness of laws and their implementation. On day 6 in Committee, I gave an example of how losing reporting requirements under article 10 of the birds directive could, for example, present a barrier to future investment in, and the roll-out of, marine renewable energy and other developments. The Government still have not said whether they intend these reporting requirements to disappear. Without amendment, we will also see a loss of environmental standards and conditions. Some obligations on member states have not been transposed into UK law, such as article 9 of the water framework directive, which requires water pricing policies to provide adequate incentives for users to use water efficiently, or article 5 of the energy efficiency directive on energy performance requirements for publicly owned buildings. We have been promised a green Brexit, and we are told that leaving the EU will not threaten the health of people or nature, so why is there opposition to amending the Bill to make those promises legally binding? Let me turn briefly to the other new clause tabled in my name. New clause 21 would ensure oversight of the transfer of functions from EU institutions to domestic institutions. It would do that by requiring the Government to establish a publicly accessible register of environmental governance functions and powers exercised by EU institutions and to make regulations that ensure that all relevant environmental powers and functions are continued. The register would allow the public to monitor and hold the Government to account on their plans for robust arrangements to be in place on exit day to deliver their ambition for a world-leading environmental justice system. The new clause also reflects strong public concern that the environmental governance gap that would arise on leaving the EU is filled as quickly as possible. To conclude, I am simply saying that if the Government want the Bill to match their stated intentions, they need to accept these provisions.
