Airports worldwide are setting aggressive zero- or low-emissions targets. To meet these targets, airports are deploying new strategies, adopting innovative financing mechanisms, and harnessing the collective influence of voluntary emissions and reporting programs. In tandem, new and affordable zero- or low-emissions technologies are rapidly becoming available at airports.

The TRB Airport Cooperative Research Program's pre-publicaton draft of ACRP Research Report 220: Guidebook for Developing a Zero- or Low-Emissions Roadmap at Airports covers all steps of roadmap development, from start to finish, using conceptual diagrams, examples, best practices, and links to external tools and resources. While the main focus of this Guidebook is airport‐controlled greenhouse gas (GHG) emissions, it provides discussion about airport‐influenced emissions from airlines, concessionaires, and passengers.

Whereas other guidebooks and reference material provide airports with information on emissions mitigation and management (for example, the Federal Aviation Administration’s Airport Carbon Emissions Reduction, ACRP Report 11: Guidebook on Preparing Airport Greenhouse Gas Emissions Inventories, and the Airport Council International’s Guidance Manual: Airport Greenhouse Gas Emissions Management), this Guidebook articulates steps for creating an airport‐specific emissions roadmap.
