Nutrient Neutrality: Levelling-up and Regeneration Bill

Debate between Baroness Scott of Bybrook and Baroness Parminter

Tuesday 5th September 2023 Lords Chamber

[Baroness Scott of Bybrook (Con)]

In the Levelling-up and Regeneration Bill we address pollution at source by placing a new statutory duty on water companies in designated catchment areas to upgrade wastewater treatment works by 2030. Interestingly enough, the analysis suggests that this will lead to about a 69% reduction in phosphorus loads and around a 57% reduction in nitrogen loads in total from wastewater treatment works across all the affected catchments, reducing a significant source of nutrient pollution and supporting the recovery of habitat sites most affected by this pollution. This is on top of the much wider improvements being driven forward through our plan for water.

[Baroness Parminter (LD)]

My Lords, when the Minister introduced the Levelling-up and Regeneration Bill into this House on 19 December, in accordance with the Environment Act, she made a statement. I quote from the front page of the Bill:

“Baroness Scott of Bybrook has made the following statements under section 20(2)(a) and (3) of the Environment Act 2021 … In my view … the Bill will not have the effect of reducing the level of environmental protection provided for by any existing environmental law”.


Given that, as my noble friend Lord Teverson said, the Government’s statutory watchdog, the OEP, has said that the amendments that she has tabled to this Bill to reduce water quality will demonstrably reduce the environmental protection afforded by current laws and that they are a “regression”, does she stand by her statement?

[Baroness Scott of Bybrook (Con)]

Yes, I stand by our statement. As I think I have said before, we do not accept that this constitutes a regression on the environmental outcomes and therefore we do not agree with the Office for Environmental Protection, because it took into account the amendments without the mitigation alongside them, as I understand. The package of environmental measures, which are backed by significant additional investment, will more than offset that very small amount of additional nutrient discharge attributed to the development of 100,000 houses between now and 2030. So, I do not agree with the noble Baroness. I stick by what I said because we are mitigating any small amount of additional nutrient discharge.
