Under Mark’s stewardship, CO2balance soon became one of the leading carbon management companies in Europe and was a key and founding player in the setting up of ICROA. As the market developed, Mark saw the opportunity to extend CO2balance’s reach, and to move further in to the carbon project developer space.

In 2006, CO2balance was established as a company in Kenya, marking the beginning of CO2balance’s instrumental role as a carbon project developer in the region.
