vehicle emissions
Cars' atmospheric pollution
Vehicle emissions are the pollutants and gases released by cars, trucks, and other motorized transport.
The term typically refers to exhaust from internal combustion engines—carbon dioxide, nitrogen oxides, particulate matter—though it can include evaporative emissions from fuel systems.
Vehicle emissions are central to debates about air quality, climate change, and transportation policy: The city implemented strict vehicle emissions standards.
