The State Government has a plan to reduce greenhouse emissions. This plan will help Australia meet its international commitments under Kyoto Protocol. Increased public transport use will help reverse the rapidly growing greenhouse gas emissions. This will not only improve air quality but also reduce transport costs and increase NSW's competitive advantage. Another strategy to increase air quality is to promote the use of public transport for those travelling to work. A number of initiatives have already been undertaken by the State Government these include improving train services to commuters, expanding the rail network and better planning of urban developments to reduce the need for travel by car.
