We have been measuring and managing our direct emissions for many years, especially with respect to our three greatest sources of impact; our manufacturing fuel combustion, our electricity use, and our global sales fleet. AbbVie has a comprehensive environmental management program aimed at reducing our emissions from each of these sources. We work across the value chain to reduce our carbon emissions, and we encourage our suppliers, distributors, and other stakeholders to reduce their impact as well.
Examples of our carbon reduction activities include:
Because energy use is directly proportional to carbon emissions, energy conservation not only reduces environmental impact, but also generates cost savings. Since 2006, the pharmaceutical manufacturing plants within AbbVie have reduced energy consumption by 18 percent by installing cogeneration systems, installing solar energy, funding energy efficiency projects, and rationalizing operations. These energy reductions have resulted in more than 500 million pounds (250,000 tons) of carbon reduction.
AbbVie's 3,100-vehicle U.S. sales fleet accounts for approximately 5 percent of our global emissions. Since 2006, we have reduced the U.S. fleet's carbon emissions by about 30 percent. We have achieved this performance through both vehicle selection and program changes.
