Carbon mapping & quantification

CarbonSphere - Environmetnal Services - GeoTerra.png

GTI brings a wealth of experience to support your forest monitoring and carbon quantification activities and requirements. This global quality experience and capability is internationally recognised by GTI’s accreditation by VERRA international Gold Carbon standard as the African regional preferred supplier of international standard carbon assessment support work. This accreditation is a result of the collaborative capabilities and skills available through the long-standing relationship between GTI and The Cirrus Group (Dr Tony Knowles). The GTI-Cirrus team brings together the expertise and experience required to explore, develop and report each component of nature-based carbon offset projects, to help monetarize your resources. The team have worked together on numerous REDD+, reforestation and conservation agriculture projects located in sub-Saharan Africa and South America.

Why is accreditation important?

Companies often ‘pledge’ environmental sustainability (also known as greenwashing) but without registering their programs with a carbon certification body. Verra has established itself as a pioneer in the field of sustainability, particularly in relation to carbon markets and its origins trace back to 2005.
