Airport Carbon Accreditation at Oakland International Airport

The Airport Council International (ACI) Airport Carbon Accreditation (ACA) is an institutionalized carbon management certification program for airport to assess and manage airports in reducing its carbon emissions.  There are 6 levels of certification (Mapping, Reduction, Optimization, Neutrality, Transformation, and Transition) that airports achieve towards comprehensive carbon management with the goal of lowering the airport’s carbon footprint.

Oakland International Airport (OAK), owned and operated by the Port of Oakland (Port), is one of three major commercial airports serving the Bay Area and has approximately 2,600 acres of
aviation-related facilities. It has served the air travel and air cargo needs of the Bay Area for over 90 years. OAK facilities include terminals, airfields, a consolidated rental car center, parking, air cargo, corporate, general aviation, a municipal golf course, and maintenance facilities. OAK’s commercial passenger terminals (Terminals 1 and 2) have a total of 29 gates and include the International Arrivals Building.

In alignment with the Port Sustainability Policy (Board Resolution Nos. 20467 and 01346), the Port commits to incorporating climate resiliency considerations into its planning, management, development, operations, goal setting, and performance measuring processes at OAK. Port participates in ACI’s ACA program, an international program which commits airports to complete greenhouse gas inventories. Port conducts a comprehensive accounting of greenhouse gas emissions and commits to decreasing these emissions through implementation of reduction measures from sources within OAK.
