Introduction 5 of establishing GHG reduction initiatives at a diverse range of airports across the United States. By specifically detailing 17 case examples of practices identified in ACRP Report 56 and by considering a broad spectrum of additional data regarding GHG reduction strategies put into place following the publication of ACRP Report 56 in 2011, this report attempts to provide timely, realistic, and useful data for U.S.

8 Airport Greenhouse Gas Reduction Efforts airports are installing vehicle charging equipment that allows airlines to consider programming replacement of older diesel units with electric-powered ones. Other vehicles that operate on the airside, including aircraft tugs and fuel delivery vehicles, are currently fueled by diesel.

12 Airport Greenhouse Gas Reduction Efforts Airports do not work in isolation to reduce emissions. Often they collaborate with local government to develop municipal or county climate plans; lessons learned are then shared with other departments within the local government, such as public works, that may be grappling with similar challenges.

Introduction 13 electric ground support equipment, alternatively fueled vehicles, renewable thermal projects that directly offset emissions from building heating systems, and other airport air quality improvements. The funding is discretionary, meaning it does not limit the airports' funding for typical airport improvements (also referred to as entitlement funds)
