zero emissions

Completely pollution-free output

Zero emissions describes processes, vehicles, or systems that release no pollutants or greenhouse gases during operation.

The term appears most often in discussions of electric vehicles, renewable energy, and climate policy.

While a car may be zero emissions at the tailpipe, critics note that the electricity powering it may come from fossil fuels, making the broader environmental impact less clear-cut.

The city aims to have a zero emissions bus fleet by 2030.
