UK Land Carbon Registry

The UK Land Carbon Registry is the database that stores and publicly displays data about the status of Woodland Carbon Code and Peatland Code projects and ownership and use of carbon units.  Managed by IHS Markit, it records transactions and provides a public and transparent picture of UK-based Woodland and Peatland Carbon Units.  All Projects and Carbon Units must be recorded on the UK Land Carbon Registry.

Number of Woodland Carbon Units available on the UK Land Carbon Registry - as of 31 Dec 2021

1 Carbon Unit = 1 Tonne of Carbon Dioxide Equivalent

'Available for sale' units are still with the project developer - Find out how and where to buy.

'Already Sold' units are either transferred from the project developer to another market participant's account, assigned to a buyer by the project developer (if PIU) or retired by the final user (if WCU).

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).

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

Delivery of verified Woodland Carbon Units over time

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 PIUs to WCUs over that time period (black line), and the cumulative sequestration of validated projects over that time (bars). Note that around 2/3 of units are already sold as PIUs (see table above - all the assignments and a proportion of the holdings are already sold).  As more projects are validated to the standard, both the conversion rate and the projected cumulative verified units will increase. Buffer Units are not included on the chart.
