As one of the largest energy delivery companies in the mid-Atlantic region, PHI is subject to annual greenhouse gas (GHG) emissions reporting obligations by the Environmental Protection Agency as well as to state-level GHG reporting requirements. Since 2002, we have reported direct (Scope 1) and indirect (Scope 2) GHG emissions data as well as reduction and mitigation initiatives through the Voluntary Reporting of Greenhouse Gases program administered by the U.S. Department of Energy's Energy Information Agency. We have been recognized by the Energy Information Agency for demonstrating commitment to voluntary environmental protection through actions taken to reduce or capture greenhouse emissions.
In addition, we voluntarily report our Scope 1, 2 and 3 greenhouse gas emissions and reduction activities as part of the CDP’s annual investor information questionnaire. Scope 3 emissions include indirect GHG emissions from sources not owned or directly controlled by PHI, but are related to our activities. For example, employee travel and commuting is a Scope 3 GHG emission.
In 2013, we continued to track progress in reducing emissions over time. We also obtained independent third-party verification of our corporate GHG emissions inventory. This independent verification improved overall confidence in our inventory. In addition, through this process, we identified areas for improvement, including expansion to smaller sources.
Our GHG emission inventory includes all material GHG emission sources as shown in the following table and chart. In 2013, our GHG emissions totaled approximately 1.4 million metric tons of CO2 equivalents (CO2e). This is 35 percent lower than our emissions in 2010. Our direct GHG emissions (Scope 1) equaled 217,588 metric tons of CO2e. This represents a 68 percent reduction in our direct emissions from 2010 levels. These reductions are a primary result of our decreasing SF₆ (sulfur hexafluoride) fugitive emissions.
