Since 2010, BWOC has reforested a total of 155 hectares of land in the United Kingdom with 200,000 trees, thereby offsetting 43,000 metric tons of CO2 . In 2015, the BWOC project in Harperrig, UK—where 10,700 trees had been planted five years earlier—was recertified under the UK Woodland Carbon Code. This recertification after five years marks a new step in the Woodland Carbon Code certification process, which Harperrig was the first project to complete.
