A look at 2015 GHG emissions
Overall GHG decline
Norfolk Southern’s total greenhouse gas emissions – Scope 1 direct emissions and Scope 2 indirect emissions – declined by nearly 2 percent in 2015.
The decrease reflects a 2.4 percent drop in business volume as measured by revenue ton-miles of freight moved by NS’ diesel-burning locomotive fleet, the main source of NS’ direct GHG emissions. In addition, NS reduced by 6.1 percent its Scope 2 emissions related to electricity use at railroad offices and facilities. This drop is attributed mainly to a milder winter, systemwide energy efficiency improvements, and the midyear closure of the company’s Roanoke corporate office, part of an initiative to streamline business operations.
