  1. Introduction

This report describes the relevant policy analysis of air pollution based on the case study of Beijing and Hong Kong in China. As is known, air pollution turns out a serious problem due to a rapid economic development, especially in the developing countries. Therefore, in terms of China, a typical representative of underdeveloped countries, it becomes significant to make policy analysis relating to what the situation of air pollution is and what are the measures it takes to solve the problem. At the same time, the language is another consideration for making such a choice of China.

Beijing, as the capital of China and Hong Kong, the special administrative region belongs to this country, on the one hand, there exist many similarities including living standards, industry patterns, social development as well as humanistic atmosphere; on the other hand, they are distinct from management philosophy and political system. However, they are both confronted with a lot of air pollution problems stemming from motor vehicles and make pertinent policies to response to issues: with regard to Beijing, it can been seen from the Beijing Environmental Statement 2011 that the concentration value of the main air pollutants---SO2, NO2, CO, PM2.5 continues to ascend respectively, and according to a research by Wang Yuesi (Chinese Academy of Sciences), motor vehicle becomes the largest source of PM2.5 in Beijing. Based on this point, how to control the quantity and emission of motor vehicle is the key contribution for solving air pollution. Concerning about Hong Kong, as displayed on the environmental protection department website, urban air pollution is mainly caused by motor vehicles, particularly diesel vehicles such as trucks, buses and light buses which emit a large amount of particulates and nitrogen oxides. The pollutants are often trapped at roads flanked by very tall buildings, thereby causing the roadside levels of respirable suspended particulates (RSP) and nitrogen dioxide (NO2) to exceed the Air Quality Objectives over the years. It can be concluded from related data that air pollution caused by emissions of motor vehicles in urban area will lead to serious environmental problems, e.g. health hazard, ecosystem collapse.

Beijing government has been dedicated to controlling the emission of motor vehicles so as to further improve the air quality, but it was not effective obviously before the year of 2008. Owing to the Olympic games of 2008, it provided the government with the chance to adopt new policies to decrease vehicle emission and these programs are still under implementation because of acceptance of positive results. As for Hong Kong, to tackle this same problem, the government has implemented a host of measures to cut vehicular emissions after 1999, such as the incentive program to replace diesel taxis/light buses with liquefied petroleum gas vehicles, the adoption of tighter fuel and vehicle emission standards whenever practicable, the incentive program to retrofit old diesel vehicles with particulate reduction devices, etc. It is shown from governmental website that these measures had brought some improvements. Compared with 1999, the roadside concentrations of some of the major air pollutants have dropped in 2011: respirable suspended particulates (RSP), sulphur dioxide (SO2) and nitrogen oxides (NOx), have been cut down by 33%, 56% and 28% respectively, and the number of smoky vehicles spotted has also been reduced by about 80%. However, nitrogen dioxide (NO2) at the roadside has increased by 23% during the same period. The rise in roadside NO2 levels has resulted in an increase in the number of days with roadside air pollution index (API) reaching the “very high” level (API exceeding 100) in recent years. To further improve the air quality at the roadside and tackle the roadside NO2 problem, the government has new initiatives in 2007 and 2008 to embark on additional control measures to reduce vehicle emissions. Hence, it can be compared in many aspects in the policy of air pollution in these two cities.

Based on above consideration, this paper will mainly focus on air pollution policy caused by emission of motor vehicles in urban areas of both Beijing and Hong Kong and a series of problems analyses related to this policy will also be integrated.
