GRAS Advisory Board

GRAS has been set up and will be continuously further developed through a multi-stakeholder process, involving representatives of private companies, the research sector, NGOs, development organizations, sustainability certification schemes and administrations.

Together with our project partners, the GRAS Advisory Board forms a sound decision basis for the further strategic development of GRAS through external expert advice and scientific oversight in the key areas of competence of GRAS.

The GRAS Advisory Board was set up by the end of 2017 and meets on a quarterly basis to discuss and decide upon strategic steps of GRAS and exchange on latest important developments within the areas of remote sensing, zero-deforestation supply chains, carbon stocks, social indices, renewable resources, agricultural markets and forestry. GRAS is proud to be able to count on the following Advisory Board members:
