MANAGING OUR CARBON EMISSIONS


The need for WSP to de-carbonise and reduce the carbon emissions that result from our operations is an important aspect of our sustainability programme. All our businesses measure and report their energy use and, where possible, business travel.


During 2010 we were able to improve and add to our 2009 data. We have taken the opportunity to update and backfi ll the information published in the 2009 Annual Report, and report the revised fi gures below. In 2010, two more business units – WSP Cantor Seinuk and WSP Finland – were included in the inventory and also four more offi ces in Asia and nine offi ces in South Africa. We improved the accuracy of information by gathering more reliable data and also capturing additional emissions not previously included in the inventory. We


also improved our emissions calculations to ensure that they are more consistent and aligned with generally accepted greenhouse gas (GHG) accounting principles.


We achieved our stated aim to increase our reporting coverage with an 11% increase in the number of offi ces reporting from 2009 to 2010. The table below shows that total emissions were similar in both years; however, with a reduction in full-time equivalent staff in 2010, emissions per employee were greater than 2009.


In 2010 more than half our CO2e emissions arose from energy used in our offi ces and


one quarter from business travel by car,


which is similar to 2009. Our average CO2e emissions were 3.2 tonnes per full-time employee (FTE), ranging from 1.7 tonnes


CO2e per FTE in Sweden to 7.6 tonnes in one of our US businesses. This is to be expected given the different national energy mixes and usage patterns. In 2011 we will seek to improve further our


reporting procedures, particularly in capturing data associated with smarter working, such as video and tele- conferencing.
