A zero-emission vehicle is specifically defined as a vehicle that produces no emissions during its operation. This means that when the vehicle is in use, it does not release any pollutants such as carbon dioxide, nitrogen oxides, or particulate matter into the atmosphere.

This definition is crucial as it aligns with the goals of reducing air pollution and mitigating climate change. Vehicles classified as zero-emission typically include electric vehicles (EVs) and hydrogen fuel cell vehicles, both of which operate without combustion and, as such, do not emit harmful substances while being driven.

The emphasis on "during operation" means that the focus is solely on the emissions that occur while the vehicle is actively in use, rather than considering the entire lifecycle of the vehicle, which may involve emissions during manufacturing or energy sourcing. This distinction is important in discussions about sustainability and regulatory definitions regarding emissions standards.
