The Mohammed VI foundation for environment protection, organised on 28 and 29 July in Casablanca, a workshop on reinforcement of capacities for the 17 enterprises that signed the Qaulit’air pact, to inform and train them on how to use the GHG emission calculation tool through practical examples and case studies. This training is based on tools developed by Mohammed VI, according to ISO 14069 norms, like the use of carbon data base which gathers more than 300 greenhouse gas emission factors adapted to the Moroccan context as well as the use of the GHG result calculating tool which allows them to estimate GHG emission of an organization in a territory. This training was organised in collaboration with Moroccan general federation of enterprises (CGEM).
