Exelon’s utilities deliver electricity and natural gas to more than 6.6 million customers in central Maryland (BGE), northern Illinois (ComEd) and southeastern Pennsylvania (PECO).
Climate and Energy Targets
Exelon was among the earliest energy companies to focus on addressing carbon emissions because of its influential role as one of the largest electric wholesale and retail power generation companies in the U.S. In 2008, Exelon launched Exelon 2020, an ambitious program to reduce, offset or displace more than 15 million metric tons of greenhouse gas (GHG) emissions per year by 2020. Following its merger with Constellation Energy in March 2012, Exelon updated its Exelon 2020 goal to reflect the company’s larger size and broader scope. The updated goal of reducing, offsetting or displacing 17.5 million metric tons of GHG emissions per year by 2020 combines the original emissions target and two prior Constellation commitments, unifying Exelon’s businesses around a common objective.
From 2010 through 2015, Exelon is investing nearly $5 billion in cost-effective, clean energy projects to support the objectives of Exelon 2020. At the end of 2012, Exelon achieved more than 89% of its original 2020 GHG reduction goal, having abated more than 14 million metric tons of GHG emissions in 2012 – equivalent to taking more than 2.9 million cars off the road every year. These reductions were achieved through greening of their operations, helping customers and communities reduce their GHG emissions, and offering more low-carbon electricity in the marketplace.
