Offsetting Project

Through ClimatePartner, Independent Slate Supplies will eliminate our carbon impact by supporting a REDD+ forest protection initiative, located in Cujubim, Brazil. The project is important to ISS as we primarily source natural slate products from Brazil. By participating in this forest protection initiative, we are directly supporting the restoration of Brazilian forests.

Even though our business activity does not directly harm the Rainforest, this project gives back to everyone, both local communities in Brazil and the environment.
