The Klimaplattform der Wirtschaft (KdW) [Climate Platform for Business] was founded on the initiative of the Federal Environmental Protection Office of the City of Bern in 2007: Since then, the City of Bern and 60 partner companies have been pursuing the goal of using resources sustainably and minimising CO2 emissions. The focus is on volunteer work. All the bodies involved are expected to ensure that a new project is implemented every two years. KdW promotes the exchange of expertise between the partners through newsletters, the website (www.klimaplattform.ch) and business lunches, and publishes an annual report on the climate-related activities of its partner companies. CSD Ingénieurs SA advised KdW’s partner companies from 2008 to 2010. Since 2010, CSD annually verifies the projects submitted by the partner companies and determines the reductions in CO2 emissions achieved.
