We are reducing our use of carbon-intensive energy by including a high proportion of renewable energy. In 2006, we sourced 24% of our energy consumption from renewable energy and district heating, steadily increasing this to 45% by 2012.

In Switzerland, the percentage of electricity sourced from renewable sources, such as hydro power stations, remained at 100%. Sourcing 100% renewable energy in Germany was introduced in 2012 (see case study below). In the UK, we purchased 62 GWh electricity backed by 100% renewable sources, representing 50% of the total volume for our main London buildings. In addition, we purchased 50,000 MWh of renewable energy certificates (RECs) in the Americas electricity markets to mitigate 2012 emissions. This equates to 23% of US emissions from electricity in 2012.
