Although Sydney has comparatively better levels of air quality compared to other major cities in the world, air pollution is still a major environmental and health issue. The NSW Department of Environment and Climate Change have put the cost of this issue to human health at more than $4.7 billion each year in the greater metropolitan area. Health experts have also estimated that air pollution cause up to 1400 deaths per year in Sydney alone, and up to 2000 hospital admissions for respiratory and cardiovascular illnesses.

According to the NSW Government’s 2009 State of The Environment Report, vehicle ownership growth now outstrips the population growth as each household is now estimated to own 1.49 cars and take 16.3 million car trips totalling 132 million kilometres daily.
