Is a political will of the Government needed in improving the air qual(2)
The air pollution in HK mostly comes from vehicles exhaust. Reducing vehicle emissions pollution， the key is to improve the combustion engine design and improve the quality of the combustion of gasoline so that the petrol can be full of burning， and harmful emissions can be reduced. Another way to reduce vehicles exhaust is to advocate people to use public transport instead of private cars. So built a comprehensive coverage of transport networks can be a good way to increase usage of public transport. Reduction of air pollution， can improve the air quality， and the surroundings can be healthier， the cost of health care can be reduced， so the SES can be increased as consequence.
Conclusion
No matter to build the public transport networks， or rational distribution of industry， or fully concerned about the Sustainable Development， they all need to be drawn up and implemented by the government. Because only the government can fully use the resources， have the power to deploy resources and establish and implement policy effectively. Improving the environment does not mean to stop developing SES， oppositely， better environment can help better socio-economic development.
