My Lords, I, too, shall be quite brief. I am grateful to the noble and learned Lord, Lord Hope, for tabling this amendment. As he says, it is probing and, as ever, he set out very eloquently the reason why it is important. I have listened carefully to his analysis and very much agree with what he said.
As we discussed in the previous group, throughout consideration of the EU withdrawal Bill, we were reassured that environmental protection would be at least as good as that which we enjoyed in the EU. However, it is already clear that the wording in this Bill on environmental principles is a weakened version of what has gone before, particularly in the need to have only “due regard” to the policy statement. The academic experts giving evidence on the pre-legislative scrutiny of the previous version of the Bill concluded that
“the Bill does not maintain the legal status of environmental principles as they have come to apply through EU law.”
Now the noble and learned Lord, Lord Hope, is rightly raising the issue of making new environmental law, as set out in Clause 19. His amendment would require that the level of environmental protection under existing environmental law should be clearly spelled out before it is possible to say, in Clause 19(3), that any new legislation will not reduce the level of environmental protection under existing law. It would remove any ambiguity and provide a double lock on protections for future environmental legislation.
At the same time, we should acknowledge that regression often happens by stealth, and can occur at a number of levels, not just in primary legislation. For example, it could appear in secondary legislation or in the detailed policy proposals that precede it. Therefore, ideally, the scope of this provision should include secondary legislation as well. It would also make sense for a statement of this nature to be published at a much earlier stage, as part of any consultation or before a new Bill was introduced. As we have discussed in other contexts, we need accurate baseline evidence, including about the impact of existing legislation, before we can assess the effectiveness of any measures proposed in any new legislation.
So we share the concerns that the noble and learned Lord has raised in this amendment and very much hope that the Minister will feel able to take these issues on board and give a positive response.
