These products and solutions helped our customers reduce their CO₂ emissions by 210 million tons in 2009 – which is a multiple of the amount of CO₂ that Siemens itself produced with its own business activities. In the coming years we intend to further increase the contribution of our Environmental Portfolio toward reducing customer emissions – and have set a goal of at least 300 million tons in 2011.

In fiscal 2009 too, the audit firm PricewaterhouseCoopers will examine the revenue and CO₂ abatement of the Portfolio. Their examination will be based on the criteria of the Green House Gas Protocol initiative launched by the World Business Council for Sustainable Development and the World Resources Institute. In 2007 and 2008, as part of a limited assurance engagement, PricewaterhouseCoopers examined the company’s revenues, CO₂ abatement and basic methods for determining which products and solutions should be included in the Environmental Portfolio, and approved them without qualification. Details are provided in our current Sustainability Report and the "Energy efficiency and environmental care" brochure.
