Vehicles emit air pollutants that are harmful to human health and the environment:
The transport sector is one of the main sources of pollutants in the world. Tool 1 provides an introduction to vehicular air pollutants. Tool 2 provides background information on the relationship between vehicle characteristics, fuel quality, and emissions.

Air pollution affects your health:
The World Health Organisation estimates that 800,000 people die prematurely every year due to urban air pollution. Tool 3 describes and explains these health effects; Tool 4 provides examples of the human health impacts of poor air quality in selected cities.
Air pollution affects natural and built environments:
Emissions from transport negatively impact physical surroundings, which in turn affects human livelihoods. Tool 5 describes air pollutants and provides information on how they affect these environments.
Transport emissions contribute to climate change:
Climate change is the most serious long-term environmental threat facing the world. Tool 6 provides an explanation of how climate change works, and describes the various sources of greenhouse gases and effects of climate change.
