About the Brazil GHG Protocol Program

The Brazil GHG Protocol Program was launched in 2008 and has 77 member
companies. The Program promotes voluntary GHG emissions management by
building technical and institutional capacity for emissions accounting
and reporting at the organizational level. It is a partnership between
Brazil’s Ministry of Environment, the Brazilian Business Council for
Sustainable Development (CEBDS), the Fundação Getulio Vargas, the World
Business Council on Sustainable Development and the World Resource

international accounting tool for government and business leaders to
understand, quantify and manage GHG emissions.
