Iride Inglewood is a microtransit project funded by the Los Angeles World Airports in partnership with the neighboring City of Inglewood. Prior to Iride, essential staff reported pain points like the unreliability of transit and the burden of monthly parking. The service provides a 100% free, electric microtransit option that brings employees from Inglewood and Lennox directly to the terminals. To improve efficiency, LAWA included access to the restricted lanes in the arrivals level of the LAX horseshoe. The restricted lanes allow Iride to travel virtually congestion free through the busiest points of LAX, meaning employees are dropped off and picked up directly in front of the entrance to the terminals. It has demonstrated the benefits by reducing commute times for employees from 60 minutes to the current metric of under 25 minutes while reducing carbon emissions from private vehicles.

San Francisco International Airport’s introduction and use of Sustainable Aviation Fuel required innovative solutions and partnerships. SFO has integrated the Sustainable Aviation Fuel into the existing jet fuel supply chain, from refinery to pipeline and from airport to airplane through a partnership with Neste, influenced the California Air​​ Resources Board to expand the Low Carbon Fuel Standard to offer the opt-in inclusion of Sustainable Aviation Fuel, and signed a Memorandum of Understanding with Neste and a group of eight airlines and fuel producers. The agreement was the first of its kind to include fuel suppliers, airlines, and airport agencies in a collaborative effort to accelerate the global and local transition to Sustainable Aviation Fuel. Thanks to these efforts, SFO can serve as a model for similar incentive programs worldwide.
