Minimizing Greenhouse Gas Emissions
We mitigate our impacts on climate change through a precautionary approach to environmental stewardship and through a reduction in greenhouse gases (GHG) that we emit. We have reduced our emissions levels both on an absolute basis and on an intensity basis per thousand air-conditioned square feet since our baseline year of 2007. We are delighted to have surpassed our short term target of 10 percent improvement in absolute emissions by 2013 one year early. We are on track to achieve our long-term target of 40 percent reduction in greenhouse gas emissions per square foot of air-conditioned space by 2025. In 2012, we reduced greenhouse gas emissions by 4.6 percent on an absolute basis and by 5.4 percent on an intensity basis, mirroring the energy efficiencies we achieved during this period.
We continue to consider opportunities to increase our use of renewable fuels, such as the use of vegetable oil from our kitchens as a source of bio-fuel, as ways to further reduce our GHG emissions.
