sustainable fuel
Renewable power source
Sustainable fuel is energy derived from sources that can be renewed or replenished without depleting natural resources or causing long-term environmental harm.
The term covers biofuels made from plants, hydrogen produced with clean energy, and synthetic fuels engineered to be carbon-neutral.
Airlines are investing in sustainable fuel to reduce emissions.
The sustainability of any particular fuel is often debated—what counts depends on how you measure environmental impact across production, use, and disposal.
