WASHINGTON – Airports across the country are more sustainable thanks to funding from the Federal Aviation Administration. As part of nearly $268 million in grants, about $92 million will go to 21 airports for solar panels, electric buses, charging stations and electrification studies; investments that support good-paying jobs and their local communities. Also, as a part of this sustainability effort, the agency is providing funding to help general aviation airports safely transition to unleaded fuel for piston-engine aircraft.
