We see it in the international examples as well. We won't get to the end state if we don't clearly state in the law what is required to get there. That's what accountability means: Parliament expressing the desire to get to a certain end state and then prescribing what the government must do in order to show that it is getting there.
In the U.K., the environmental targets for biodiversity—these are regulations made under the Environment Act 2021—set very detailed targets for species recovery, lowering extinction risk, species abundance and habitat restoration and creation.
We don't want to be a laggard in this area. That is the international best practice that we should follow.
