About the Brazil GHG Protocol Program

The Brazil GHG Protocol Program was launched in 2008 and has 77 member companies.

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 Institute. The Greenhouse Gas Protocol is the most widely used international accounting tool for government and business leaders to understand, quantify and manage GHG emissions.
