Air pollution can have a serious effect on people?s health, cause damage to the environment and cause a range of subsidiary damages. For example, the impact of poor air quality (from man-made particles alone) was estimated to reduce average UK life expectancy by about eight months in 2005, creating an annual cost of up to ?9.1??21.4 billion.

Since 1997 all UK local authorities have had statutory duties for local air quality management (LAQM) for seven key air pollutants under Part IV of the Environment Act 1995.
Australian air quality regulation includes AS 1668.2, which seeks to regulate the indoor air quality environment by mandating the levels of outside air entering an air-conditioned building and AS 3666 which regulates maintenance of cooling towers to reduce the incidence of airborne contaminants entering air intakes.
