If a new amendment is put forward, of course we will look at it and consider its legal implications. I can give that assurance.
On Amendment 112, our starting point is that the new statement of principles and the environmental body should cover England and environmental matters that are not devolved. To respond to the point made by the noble Lord, Lord Wigley, if the devolved Administrations would also like to take action on these issues, we are open to co-designing the proposals to ensure they work more widely across the UK. We would need to take account of the different government and legal systems in the home nations, as well as the different circumstances in the different parts of the UK. This amendment risks compromising consideration of these important issues as well as the wider devolution settlement by requiring the UK Government and devolved Administrations to consult jointly on UK-wide proposals for governance and principles.
On Amendment 113, the secondary legislation made using the powers under Clause 7 will be subject to parliamentary oversight, using well-established procedures. This amendment would require us to make all the regulations within one month of Royal Assent. This would not allow time for stakeholder consultation and would also not allow sufficient time to make all the SIs—noting that affirmative SIs take longer than one month to be laid and made.
Many areas of environmental policy are devolved. This amendment would require the Secretary of State to make regulations for all the UK, which would be contrary to the devolution settlement. It would also require the creation and maintenance of a register of functions indicating who is responsible to perform them before leaving the EU and who will be responsible after we leave the EU. This is a bit of bureaucratic procedure that has no added value. The SIs under the Bill will set which UK body will perform functions, such as the various regulatory functions.
On Amendment 108, the UK Government laid legislation transposing the national emission ceilings directive in Parliament on 1 February 2018, demonstrating our clear commitment to improving air quality. This legislation implements ambitious, binding emission reduction commitments for 2020 and 2030 into domestic law. Air quality has improved significantly over recent decades, with the UK reducing emissions of all the major five air pollutants. For example, since 1970 we have reduced emissions of nitrogen oxides by 69%, emissions of PM10 by 73%, and emissions of PM2.5 by 76%. Emissions will continue to reduce thanks to the action we have already taken, and we will publish a new clean air strategy in 2018 setting out how we will work towards our 2020 and 2030 commitments.
The Bill will ensure that the body of existing EU environmental law continues to have effect in UK law. It will be for Parliament—and, in some cases, for the devolved legislatures—to make any future changes in legislation after we have left the EU. The power under Clause 7 will be used to amend legislation to ensure continued operation of legislation, enabling the Government to continue to meet their environmental objectives.
Amendment 186, tabled by the noble Lord, Lord Adonis, and to which the noble Baroness, Lady Brown, spoke, would compel the Government to set out a strategy on
the EU emissions trading system. This amendment is unnecessary given that our Clean Growth Strategy, published last year, clearly sets out our guiding principles on reducing emissions. We are considering the UK’s future participation in the EU ETS after our exit. We remain firmly committed to carbon pricing as an emissions reduction tool, while ensuring that energy-intensive and trade-intensive businesses are appropriately protected from any detrimental impacts on competitiveness.
