Opportunities to Improve Air Quality
Vehicle emissions affect air quality. They also add significantly to atmospheric CO2, which causes global warming. Tackling congestion provides one of the greatest opportunities to improve air quality. Other opportunities to reduce emissions include:
- reducing the need to travel, through planning policies such as ‘Urban Renaissance’, and increasing the number of people living in town and city centres
- encouraging more environmentally friendly modes of travel including walking, cycling and public transport
- promoting fuels that produce fewer emissions and vehicles that are more efficient
- ensuring traffic can flow efficiently, e.g. by reducing stop-start conditions
- encouraging drivers to switch off their engines when stationary
The Air Quality Strategy outlined later in Chapter The Strategy includes all these elements.
