Sizewell C will boost local biodiversity

We will look after the local environment before, during and after the construction of Sizewell C.

Wildlife has thrived for decades around the existing Sizewell B station and before that at Sizewell A. We will build on a great track record and continue to protect this precious area of the Suffolk coastline. 

The measures we are taking to look after nature include:

  • Designating 250 hectares of land for wildlife 
  • Increasing biodiversity around the power station by 19%
  • Setting up an Environment Trust to manage the Sizewell estate and promote rewilding

We are not building on any land owned by RSPB Minsmere. Where a small part of our boundary meets RSPB land, we are creating a new area of wetland to allow wildlife to thrive. We will limit construction when necessary to reduce noise and we will use directional and low-level lighting. We are confident our plans will not have an impact on this important nature reserve.  

Once Sizewell C is constructed, the nuclear licensed site will amount to 69 hectares - that's less than 0.2% of the total area of the Suffolk Coast and Heaths AONB. Nuclear produces a lot of electricity from a very small land footprint leaving more room for nature.  

The biggest threat to biodiversity is climate change. By lowering carbon emissions, nuclear energy will help to protect the natural environment. 

Carbon emissions and Sizewell C

Sizewell C will provide low-carbon electricity for 6 million homes. It will also pave the way for other low-carbon forms of energy production, including Hydrogen and Direct Air Capture (DAC).

Improving biodiversity through our nature reserve

Sizewell C has created a nature reserve at Aldhurst Farm featuring sixty hectares of grassland and heathland and six hectares of fantastic wetland. The reserve will include areas open to the public for recreational purposes and is already benefitting a variety of wildlife including water voles, otters, eels, amphibians, reptiles and birds, as well as rare plants. This rewilding conservation project will improve the biodiversity of the area, which is vital for restoring nature and helping fight climate change.

net gain in biodiversity

The measures we are taking will protect and enhance nature and, in the long run, will lead to a 19% net gain in biodiversity. 

The Sizewell estate is already more than 600 hectares in size. With the inclusion of new land to mitigate the effects of construction on wildlife, it will increase to around 800 hectares (that's almost the size of 1,000 football pitches). 

We are working with others to set up an independent Environment Trust which will manage the land and promote rewilding. This work will go beyond the ecological mitigation and landscape measures set out in our application for planning permission. 


Nuclear looks after wildlife

Existing nuclear power stations like Dungeness B demonstrate how nuclear and nature can exist happily side by side.

Dungeness B sits in the middle of Dungeness National Nature Reserve in Kent. Its diverse landscape is home to many unique plants, animals and birds. Staff at the power station helped to conserve what was, for a long time, the only known colony of Sussex Emerald moths in the UK. 

Hundreds of rare and notable species have benefitted from biodiversity programmes at EDF's nuclear power stations.
