Helping our environment

Climate change is predicted to have long-term consequences for our economy, our environment, and public health and safety. To do its part to reduce the threat, King County International Airport-Boeing Field aims to be carbon neutral by 2030 for Scope 1 emissions (direct emissions controlled by KCIA) and Scope 2 emissions (indirect emissions from purchased electricity, heating, and cooling in buildings). These actions help us prepare for climate change and support King County's Strategic Climate Action Plan.

KCIA has achieved Level 2 of the Airport Carbon Accreditation Program (ACAP), demonstrating actual reductions in greenhouse gas emissions. In 2021, KCIA was the first general aviation airport in Washington state to join the effort and achieve ACAP Level 1. ACAP is the only airport-specific, internationally recognized carbon management standard. Through its six levels of accreditation, ACAP can be used by any airport to manage its environmental impact, and each level reached increases an airport's ability to mitigate the effects of climate change. There are just 64 airports in North America, and 510 worldwide, that are engaged in ACAP.

KCIA is also the first airport in the U.S. to begin the IATA Environmental Assessment (IEnvA) program, a new international certification program that helps airports and other air transport industry stakeholders towards greater environmental sustainability.

The airport has demonstrated its commitment to environmental stewardship and sustainability in other ways as well. For example, KCIA has finalized purchase details for a hybrid electric fire engine, the first airport in the nation to do so. The new Striker Volterra 6x6 Aircraft Rescue and Firefighting (ARFF) vehicle is expected to be delivered in mid-2024. In addition, the airport is working to electrify more of its ground vehicle fleet. The airport also meets or exceeds King County standards for construction and demolition debris landfill diversion rates.

KCIA is being assisted in its efforts by WSP, an internationally recognized, locally dedicated engineering firm that has helped airports of all sizes in planning and design for a more equitable, environmentally sustainable future. WSP and the airport worked together to develop a ten-year work program to achieve carbon neutrality and establish annual carbon footprint reporting. Our 2021 carbon footprint calculations show a 44% total emissions reduction at KCIA compared to 2007.

Air Monitor Program

In addition to our efforts to track and reduce greenhouse gas emissions, KCIA also has Purple Air Monitors that display live reports of air quality in the neighborhood surrounding the airfield. These sensors monitor small particulates in the atmosphere that may have an impact on health.
