The Port of Seattle, which operates Seattle-Tacoma International Airport (Sea-Tac), and fifteen Airlines have established a Memorandum of Understanding to work together to develop a strategic plan to reduce carbon emissions and air pollutants at Sea-Tac, including certain aircraft emissions.

Through strategic engagement with the Airport and its Airline partners, Ramboll led the development of a plan that explores a variety of mechanisms to achieve carbon and air emission reductions, including technology, infrastructure, operational, and aircraft technology solutions. The strategy identifies airside measures that require direct oversight by airlines as well as landside measures that require collaboration among multiple project partners. 

Key challenges

Identifying cost-effective solutions to achieve GHG reductions equivalent to the reductions from sustainable aviation biofuels


The project established a multi-year roadmap to achieve the Port of Seattle’s Century Agenda emission reduction targets for Scope 3 emissions and evaluated greenhouse gas reduction potential and cost of each strategy action.
