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 met our fiscal 2012 target of reducing our per employee carbon emissions approximately 30 percent from our fiscal 2007 baseline, achieving a more than 33 percent reduction. Our efforts to encourage the adoption of virtual-collaboration technologies continue to help us manage air travel, even as we have expanded into growth markets and increased our fiscal 2012 global year-end headcount by 87,000 employees, or approximately 50 percent, since 2007. We remain focused on improving our performance and set a new global target: by the end of fiscal 2015, we plan to reduce our per employee carbon emissions 35 percent against our fiscal 2007 baseline. Accenture proactively manages energy use throughout our locations worldwide. Since fiscal 2009, our global energy-efficiency programs have helped us save approximately 250,000 Megawatt hours of electricity, which also avoided nearly 160,000 tons of carbon.
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.
