Sizewell C has published its second Annual Sustainability Report, outlining progress on environmental, social and economic commitments as construction of the new nuclear power station continues in Suffolk.
The report shows the project has now spent £4.89bn with more than 1,000 UK suppliers, including £1.35bn with businesses across the East of England. More than 2,000 people are currently working on site, with over one-third coming from the local area.
The project has also created 120 apprenticeships to date, including 80 for people from Suffolk. Sizewell C aims to deliver 70% of its construction value through British suppliers over the lifetime of the project.
On the environmental front, the report highlights the reuse of more than 53,000 tonnes of recycled concrete aggregate from the neighbouring Sizewell A and Sizewell B sites. The company said it also remains committed to achieving at least 19% biodiversity net gain, almost double the national requirement, with recent assessments suggesting the final figure could be even higher through improved habitat connectivity.
The report cites encouraging signs across the project’s nature reserves, including successful breeding of natterjack toads, increased marsh harrier activity and sightings of rare species such as the grayling butterfly.
Sizewell C also outlined plans to keep construction emissions below 2.1MtCO₂e by eliminating diesel use on site by 2030, using 100% low-carbon electricity and increasing the use of lower-carbon construction materials.
Community investment has also continued, with the Sizewell C Community Fund providing more than £3.9m to local projects.
