zero emission

Completely clean output

Zero emission describes technologies, vehicles, or processes that release no pollutants directly into the atmosphere during operation.

Electric cars are zero emission at the tailpipe, though the electricity powering them may come from polluting sources.

The term appears frequently in environmental policy and automotive marketing: California's zero-emission vehicle mandate, a zero-emission bus fleet.
