Sustainability report
Sizewell C is already showing how major infrastructure can deliver lasting social, economic and environmental value for the UK.
Our first Annual Sustainability Report, published in October 2025, outlines progress and ambition across five key themes: Jobs, Skills & Economic Growth, People, Communities, Nature & Environment, and Climate.
With 1,500 people on site, 400 UK suppliers, and £2.8 billion in contracts awarded – including £126 million to Suffolk businesses – the project is driving opportunity and growth nationwide.
