The Game and Wildlife Trust Conservation (GWCT) has begun piloting its new Hedgerow Carbon Code, a year on from receiving an £81.5k grant from the government’s Natural Environment Investment Readiness Fund for the project.


“We now have a trial Hedgerow Carbon Code,” director of Policy and the Allerton Project at GWCT, Dr. Alastair Leake, said.

“Pilots have begun with three arable farms in England, where we are evaluating the practicality of the code and the carbon calculation tool and developing it with the input of farmers on the ground.

“We are also looking at ways in which land managers who are already generating carbon and biodiversity benefits through good hedgerow management can be recognised and rewarded.”

The code will encourage hedgerow habitat improvements to increase the amount of carbon stored by hedges.

The GWCT has also said that the code will help contribute to British farming’s net-zero target and help boost biodiversity.

It will also, it says, allow land managers to calculate and verify the carbon capture potential of their hedgerows, enabling them to trade carbon credits – a market with a potential value of £60 million.

‘Sustainable farming incentive’

The UK government has set out its ambition for British agriculture to be zero-carbon by 2050, while the National Farmer’s Union (NFU) has a more ambitious target of 2040.

Independent statutory body The Climate Change Committee has identified hedgerow planting as a way to help reach that target.

The Hedgerow Carbon Code includes a tool which will enable the carbon stored in a hedge to be calculated and verified, incentivising land managers to plant and manage hedgerows – an important part of the government’s new Sustainable Farming Incentive.

The tool also has the potential to be developed further to monitor hedgerow biodiversity for calculating biodiversity credits.

“Going forward, planting and managing hedgerows well will enable land managers to access the Sustainable Farming Incentive and open opportunities to generate income from carbon and biodiversity credit trading,” Dr. Leake said.

“That can only be good news for UK agriculture, climate change and British wildlife.”

Hedgerows and carbon


Hedgerows sequester carbon at twice the rate of woodland because of their three-dimensional linear structure and England’s hedges already store nine million tonnes of carbon.

Similar to the Woodland Carbon Code, the new code will become the quality assurance standard for hedgerows and aims to generate hedgerow carbon credits, independently certified by Organic Farmers & Growers – who already do the same for the Woodland Carbon and Peatland Codes.

“Many arable farms have old hedgerows which are no longer needed for their primary function of containing livestock, so there is little incentive to maintain them,” Dr. Leake said.

“But, if we can attach a value to them, through recognising their carbon sequestration and biodiversity benefits and rewarding farmers for these, then we could incentivise further hedgerow restoration.”

The Hedgerow Carbon Code and Kellogg’s

Kellogg’s, as part of their ‘Origins’ programme, has been working with the GWCT’s Allerton Project demonstration farm, where the code is being developed.

Manager of the Origin’s programme in the UK on behalf of Kellogg’s, Duncan Rawson, said: “The Origins Programme invests into sustainable farming practices, working with Kellogg’s farmers to help improve productivity and environmental performance, with a particular focus on climate change and biodiversity.

“Quantification of the on-farm sequestration of carbon is important to demonstrate the range of carbon benefits which agriculture can provide and to enable the food sector to meet carbon reduction ambitions.”
