UK Woodland Carbon Code launched on Markit Environmental Registry, enhancing transparency and accountability in the trade in British Woodland Carbon Units.  Carbon dioxide (CO2) sequestered, or absorbed, by WCC-validated woodlands in the UK can be traded, and the development enables changes of ownership of each tonne to be tracked. The registry will also record when projects are registered and credits are listed, and when carbon units have been “used” by a company in its carbon account. News release.
