Reducing air pollution

Reducing air pollution from power stations

Power stations generate electricity. By reducing electricity use, everyone can reduce the emission of air pollutants from power stations.

Sulfur dioxide may be removed from the waste gases by a process called gas scrubbing.

Reducing air pollution from cars

The emission of air pollutants from cars may be reduced by people using their cars less by, for example:

  • walking
  • taking public transport
  • car sharing
  • cycling

Engineers are developing engines for vehicles that are more efficient. This means that the engine uses less fuel and so produces less air pollution.

A catalytic converter, fitted to the exhaust of a car, changes the pollutants carbon monoxide and nitrogen monoxide into less harmful carbon dioxide and nitrogen.

The use of low-sulfur fuels has reduced the amount of sulfur dioxide in car emissions.
