Annual statistics 

You can view offical annual statistics about the Woodland Carbon Code (up to 31 March 2023) in Forest Research’s Forestry Statistics 2023 publication - Chapter 4: Carbon. 

Statistics from earlier years are also available.

Interim project statistics 

Our interim statistics provide data on Woodland Carbon Code projects up to 31 December 2023.

Interim carbon unit statistics 

Our interim carbon unit statistics provide data from Woodland Carbon Code projects up to 31 December 2023. 


Number of Woodland Carbon Units available on UK Land Carbon Registry 

1 Carbon Unit = 1 Tonne of carbon dioxide equivalent

'Available for sale' units are for sale by the project developer or a retail aggregator - Find out how and where to buy.

'Already sold' units are either transferred from the project developer to a corporate buyer's account or assigned to a corporate buyer (if Pending Issuance Units)

Landowners 'growing their own' units are owned by organisations planning to use the units that will be verified against emissions within their own company/organisational boundaries (insetting).

'Retired Woodland Carbon Units' are verifed credits which are 'retired' or taken out of use by the final user.

Woodland Carbon Code Buffer Units are units which are put aside and stored in a shared buffer pool in case of any future loss of Woodland Carbon Units.

Pending Issuance Units

Woodland Carbon Units 800 3,500 1,100 4,600 2,300 12,300

 Note: Pending Issuance Units are validated units of CO2e which are projected to be delivered/sequestered in future. Woodland Carbon Units are verified units of actual sequestered CO2e.


When will Pending Issuance Units convert to verifed Woodland Carbon Units? 

Woodlands validated to the Woodland Carbon Code will sequester carbon dioxide over the coming 100 years.

The chart below shows the projected annual 'conversion rate' of Pending Issuance Units to Woodland Carbon Units over that time period (black line) and the cumulative sequestration of validated projects over that time (bars).

As more projects are validated to the standard, more units will be available and the conversion rate will increase. Verifed Woodland Carbon Units and Buffer Units are not included on the chart.
