Motor vehicle emissions

Motor vehicle emissions are the gases and particles that come out of the exhaust pipes of cars, trucks and buses. These emissions contain pollutants that are bad for our air, water and soil. Motor vehicle emissions make up a large part of the air pollution in our cities, and if we don't reduce these emissions, it can cause serious problems for people's health and for the environment. The way we can reduce motor vehicle emissions is by improving the technology in our cars, using cleaner fuels that produce fewer pollutants, and driving less.
