It is a pleasure to serve under your chairship again, Dr Huq. I thank the Minister for his comments. He emphasised that his intention in the Bill is to continue to protect nature at the same level, but differently. He emphasised a different but not worse approach. I share his desire to ensure that even if it is different, it is not worse, but I am concerned about the way the Bill is framed.
In clause 55, we are really getting to one of several cruxes of the matter. The Secretary of State’s environmental statement on the front of the Bill states:
“the Bill will not have the effect of reducing the level of environmental protection provided for by any existing environmental law.”
A completely different opinion is expressed, however, in the letter from the Office for Environmental Protection, whose people know about this issue. I am glad that the Minister said yesterday that he is considering very seriously what the OEP said; I read the letter again in detail this morning—it is really hard-hitting.
The Minister points out that Natural England thinks there is no problem with the application of the mitigation hierarchy, but that is not the opinion of the Office for Environmental Protection. Given that Natural England will effectively have a conflict of interest under the Bill’s provisions, we need to pay serious attention to what the OEP says. I very much look forward to his promised comprehensive response to the OEP’s advice.
Amendment 20 is essential to ensure that the overall improvement test applied to EDPs, which is mentioned in clause 55, is robust, scientifically grounded and consistent with domestic and international environmental law. It is about making sure that when we talk about overall improvement, we really mean it—not on paper, not in theory, but in reality.
Amendment 119 makes a simple but essential change. Under the Conservation of Habitats and Species Regulations 2017, as set out in the OEP’s advice, there is a high degree of certainty established in statute and case law that environmental standards will be maintained beyond reasonable scientific doubt. In the overall improvement test in clause 55, however, conservation measures need only be “likely” to ensure that the environment is maintained. That leaves huge leeway for ministerial subjectivity, and it opens the door to damaging development. It is a clear regression in environmental law. Again, that is emphasised very clearly by the OEP, which states that the test in clause 55
“would be considerably more subjective and uncertain than under existing environmental law.”
How is that compatible with the statement on the front of the Bill? It cannot be.
Given that the Minister has assured us that it is not the Government’s intention to weaken environmental protections, amendment 119 would fix the loophole by replacing the words “are likely to” with the word “will”. That would mean that an EDP would require an objective test that conservation measures will achieve an overall improvement.
This amendment is not about gold-plating; it is simply about matching the level of certainty that currently exists in law and assuring the House that environmental protection will be maintained. I would be deeply worried if the Bill passed as it stands, with the weakening in certainty, because that would clearly be contrary to the Government’s statement on the front of the Bill.
Amendment 20 sets the minimum legal and scientific thresholds that must be met before an EDP can be said to pass the overall improvement test. Again, the advice from the OEP is very robust—there needs to be scientific certainty. Amendment 20 would specifically introduce safeguards when protected nature sites are involved, such as European sites, Ramsar wetlands and other internationally important conservation areas.
Amendment 20 would ensure that the Secretary of State must apply a standard of evidence equivalent to the rigorous integrity test under the Conservation of Habitats and Species Regulations 2017. This is not new law; it is a reaffirmation of the protections that have guided habitat conservation for decades, ensuring that there is no regression, as per the Environment Act 2021. The amendment is absolutely necessary, otherwise clause 55 risks watering down the existing protections.
Let us not forget what is at stake here. The UK has 658 designated special areas of conservation, special protection areas and Ramsar sites across the four nations. They include places of global ecological importance— the Norfolk broads, the Severn estuary and the north Pennines—and places that are very dear to my own heart, such as the River Wye and its catchment. These places support rare and endangered species, and are central to our commitments under the Bern, Bonn and Ramsar conventions. However, many of them are already in unfavourable condition. Natural England’s latest data shows that only 38% of England’s sites of special scientific interest are in favourable condition and many of those overlap with European sites.
This amendment would provide three layers of safeguards. First, it says that an EDP cannot be approved if it would harm the “integrity” of a European or Ramsar site, unless that harm is either fully avoided or meets the high bar set under existing habitat regulations. Secondly, it would require Natural England to demonstrate that “all reasonable opportunities” to avoid or minimise harm have been taken.
Thirdly, the point about the mitigation hierarchy is really important—we will discuss it again when we debate a future clause. It is a key concern for the Office for Environmental Protection and all who care about nature. The mitigation hierarchy means that we avoid environmental harm before we go to mitigation or offsetting. The problem with EDPs, as they are set out under part 3 of the Bill, is that they shift straight to offsetting. As I tried to explain yesterday, some things cannot be offset; irreplaceable habitats cannot be offset.
In addition, unless we are certain that offsetting is done in advance and that the habitat is linked to the one being destroyed, that could lead to the inadvertent destruction of species—for example, dormice, as I said yesterday. It is important that the Bill strengthens the commitment to the mitigation hierarchy and that that strengthening is written into the Bill, as well as ensuring that the overall improvement test is compatible with the existing level of protection under existing environmental law.
The expert advice of the OEP directly supports the points that I am making. It concluded that the overall improvement test, as currently drafted, would weaken existing legal protections, and has consequently called for amendments to ensure that the test aligns with environmental law and principles.
We also need to ensure that the UK remains compliant with international and trade obligations. Under the EU-UK trade and co-operation agreement, we are bound not to weaken environmental standards in ways that affect trade or investment. Removing or diluting protections for SACs and SPAs through a vague or permissive improvement test could fall foul of that requirement and expose the Government to legal challenge.
Fundamentally, the amendment also reflects the will of the public. More than 80% of people support strong legal protections for nature sites, even when development is proposed. I fully agree with the Minister’s articulation of the view that development does not have to come at the expense of nature—it is absolutely possible to build the houses that we need in a way that respects and indeed improves nature protection—but we can do that only if the legal framework ensures that development takes place in that way. Otherwise, there is a serious risk that the clear weakening of environmental protections, as outlined in the current drafting of the Bill, will lead to the opposite of what the Government say they want to do on the front of the Bill.
These two amendments do not prevent development. They simply ensure that development is compatible with the integrity of our most protected sites, give effect to long-standing legal protections, uphold the Office for Environmental Protection’s recommendations, and ensure that the overall improvement test is not a loophole but a genuine environmental safeguard. I strongly urge hon. Members on both sides of the Committee to support both amendments if we are serious about development going hand in hand with nature protection.
