emission-free
No exhaust produced
Emission-free describes something that produces no pollutants or greenhouse gases during operation, particularly carbon dioxide.
The term applies mainly to vehicles and energy sources: emission-free electric buses, emission-free solar power.
Critics note that "emission-free" often ignores emissions from manufacturing or electricity generation—an electric car is only as clean as the grid charging it.
