My Lords, I rise to speak to Amendments 111 and 112 in my name, and in support of Amendment 113, in the name of my noble friend Lord Fuller.
Amendment 111 would require the Secretary of State to assess the impact on the environment and animal welfare standards of the installation and generation of offshore wind energy technologies. Amendment 112, also in my name, similarly requires an environmental impact assessment, but with the focus on the decommissioning of oil and gas structures.
The threat posed by the installation and generation of offshore wind farms and tidal energy is not new to the House. Many will be familiar with these concerns, as we on these Benches raised such issues in Committee in debates on the Crown Estate Bill, and discussed the purpose of electricity generation and the Crown Estate’s role in the stewardship of our seabed.
In considering the amendments in my name and that of my noble friend Lord Fuller, we must again address the Crown Estate’s strategic and unprecedented partnership with Great British Energy, which is estimated to result in up to 30 gigawatts of new offshore wind developments reaching seabed lease stage by 2030. We should expect to see considerable and accelerated growth in offshore renewable energy projects, with offshore wind contributing significantly to these efforts. The UK is the second largest offshore wind market in the world. Under the new Government, allocation round 6 has awarded 5.4 gigawatts of offshore energy contracts across fixed and floating offshore wind and tidal stream.
The speed and scale of these planned developments raises concerns about the impact on the marine ecosystem, as expressed by bodies such as Birdlife International. As stewards of our seabed and investors in and facilitators of offshore renewable energy projects, the Crown Estate and GB Energy have a duty to assess the impact of offshore energy installation and generation. GB Energy must restrict such installation and generation if it is found to cause the environment and its associated animals harm. Environmental concerns linked to the installation of offshore energy projects and the operation of these technologies include, but are not limited to, increased noise levels, the distortion in light pollution, and the potential impact on carbon storage and the biodiversity of the seabed and its composition.
In an overview of the ecological impacts of offshore wind on the marine environment, Birdlife International highlighted the impact of the installation and operation of offshore wind farms on marine animals. It found that the installation and generation of offshore wind technologies produces underwater noise, affecting the echo location behaviour of marine mammals. Porpoises, seals and marine birds have been shown to be displaced by wind farms, with some marine birds displaying consistent avoidance behaviour during breeding seasons. Noise pollution produced by piledriving has also been found to impact the behaviour of pelagic fish.
I have briefly outlined the impacts on our environment caused by offshore wind, yet other technologies also have the potential to cause significant harm. I am grateful to my noble friend Lord Fuller for addressing the threat tidal energy poses to the fish which inhabit our seas. As he will no doubt discuss this impact in more detail, I will succinctly outline the problems associated with tidal energy generation, which is foreseen to increase rapidly in the coming years. Tidal turbines in open water could result in additional mortality caused by rotor blade collision. This is significant, as tidal waters serve as key feeding areas for fish, as well as passage corridors for migratory fish. Other risks include changes in underwater noise, electromagnetic fields and habitats, and displacement.
Finally, I hope the Minister will listen to the concerns highlighted in the amendments in this group and will confirm to the Committee that he recognises that Great British Energy is in a unique and critical position to assess and minimise the impact of offshore energy installations on our environment and the marine life which inhabits it.
