Looking after nature

The biggest threat to nature is climate change. Clean energy from nuclear will reduce carbon emissions and help to protect the environment. At Sizewell C, we are creating stunning new habitats for nature.

We are going well beyond legal requirements to mitigate the impacts of construction. Our plans will result in more local biodiversity, more nature recovery and more rewilding in the East of England.
