My Lords, the European Union (Withdrawal) Act 2018 and secondary legislation will bring existing EU environmental law into domestic law so that it continues to operate after exit. We will enhance standards through the world-leading Environment Bill and the office for environmental protection, the OEP. Our intention is for the OEP to be operational from 1 January 2021. Before that, we will remain subject to EU oversight during the transitional period in the withdrawal agreement until 31 December 2020.
