G&W’s North American operations reduced Scope 1 & 2 emissions intensity by more than 6% in 2021.


Our Scope 1 emissions consist of all G&W’s direct GHG emissions, including mobile and stationary combustion sources such as locomotives, cars, trucks and equipment, as well as refrigerants. Our Scope 2 emissions included all of G&W’s purchased electricity.

G&W’s North American operations improved fuel efficiency predominantly by retiring older locomotives in favor of more fuel-efficient models. In 2021, we also continued to invest in carbon-reduction technologies such as Automatic Engine Start/Stop (AESS) systems and Auxiliary Power Units (APUs). As of December 31, AESS and APU technology was installed on more than 25% of our locomotive fleet, and based on these installations, we expect to save more than 14,500 metric tons of CO₂e annually. We are continuing to upgrade additional locomotives with these fuel-saving technologies as part of our annual capital plans.
