Learn about how we are growing our business on an environmentally sustainable basis.
More than 80 percent of Accenture's environmental footprint consists of carbon emissions generated from air travel and electricity, and we are committed to addressing both of these areas.
Globally, we have reduced our per employee carbon emissions by more than 36 percent against our fiscal 2007 baseline—from an average of 4.0 to 2.6 metric tons of CO2 per employee. This reduction is equal to avoiding nearly 1.5 million metric tons of CO2. Notably, we achieved these results in the same period in which we increased our headcount by more than 100,000 employees, or approximately 60 percent.
We recognize that the need to travel by air for client work is often difficult to forecast, which may lead to year-over-year fluctuations in our total carbon emissions performance. Therefore, we will continue to pursue our current target of achieving a 35 percent reduction in per employee emissions by the end of fiscal 2015. We remain focused on growing our business in an environmentally responsible way, by coordinating efforts closely with our global network of employees, clients and suppliers.
Ensuring the proper disposal of electronic waste by managing our equipment through its life cycle and partnering with responsible disposal vendors is also important. In fiscal 2012, we tracked the disposal or reuse of more than 58,000 laptop and desktop computers worldwide. Approximately 99 percent of these were repurposed or disposed of in a method avoiding landfill.
We make transparency and accountability priorities, reporting annually to the United Nations Global Compact, Carbon Disclosure Project (CDP), Dow Jones Sustainability Index and FTSE4Good Index. Since 2007 we have reported annually on our environmental performance to CDP's Climate Change program. We capture our environmental risks, opportunities and methodologies in our CDP response. In 2013, Accenture was included for the fifth consecutive year among the CDP Global 500, receiving a score of 92 out of 100 and a performance score of B. We have also been included on the Dow Jones Sustainability North America Index and FTSE4Good Global Index since 2005, and we have been a member of the FTSE4Good Global 100 since 2012.
