TRANSCRIPT
Outline
1. Introduction and overview of the current state of the atmospheric pollution in the Asia-Pacific region
2. Sulfur dioxide (SO2) pollution in China
3. Carbon dioxide (CO2) pollution in China
4. Concluding remarks
Overview
• Atmospheric pollution increased significantly in the last three decades due to:– Rapid economic growth– More widespread use of motor vehicles
In the Asia-Pacific region...
• In 1992, the region accounted for 21% of the world’s commercial energy consumption (shown in Fig 1)
• Energy consumption grew by 6.2% while the global energy consumption fell by 1%
• 80% of the energy generated by fossil fuels, 40% of which was coal
In the Asia-Pacific region... Con’d
• Sulfur oxide emission increased by 80% (1970-1986)
• Sulfur dioxide emission was 50% higher than either Africa or Latin America
• Nitrogen oxide emission increased by 70% (1970-1986)
• Carbon dioxide grew 60% faster than elsewhere
In the Asia-Pacific region... Con’d
• Energy demand will double every 12 years (the world average: 28 years)
• Demand for coal will remain high (6.5% annual increase) thanks to:– The abundance of coal– Its easy recoverability
• SO2 emission triple in the next 12 years
The result…
• A significant increase of national and trans-boundary acid deposition
• Aggravating urban air pollution
• Irreversible ecosystem damage with far-reaching implications…
• In a word, the result is pretty darn BAD!!!
Sulfur dioxide (SO2) pollution
• Generated as a result of the burning of coal and petroleum
• When released into the air, it reacts with atmospheric water and oxygen to produce sulfuric acid – major component of acid rain
The acid rain…
• Has substantially harmful effects on forests, fresh water and soils
• Kills off insect and aquatic life forms
• Causes chemical weathering to statues and buildings

SO2 in China…
• In 2005, over 50% of SO2 emitted from the “Production and Distribution of Electric Power and Heat Power Industry” (11.67 million tonnes)
• In which 11.12 million tonnes were the result of “Firepower Electricity” generation

A couple of examples…
• June 8, 2004, the SO2 pollution in Guiyang resulted in a “black dust storm”.
• Nov. 12, 2004, an SO2 accident in Yichang hospitalized 108 persons.
Any optimism here?......Yes!
• A study of national income and SO2 emissions in 12 Western European countries in 2006
• Used 132 years of data
• Came up with an “Environmental Kuznets Curve” (EKC)
Compare with the current Chinese situation…
• The 2006 income per capita in China is $1,500
• Compared to the Western Europe turning points of $11,900 with regulations, and $12,200 without regulations

Carbon Dioxide (CO2) Pollution
• Atmospheric concentration of CO2 is mainly caused by:– Fossil fuel combustion– Deforestation
• A vicious domino effect:
SO2 emission → Acid rain →Deforestation →High atmospheric CO2 concentration→Greenhouse Effect & Global Warming
In 2002 UN statistics…
• U.S. was the largest CO2 emitter (24.3%)
• European Union (15.3%)
• China (14.5%)
• India, Japan and South Korea ranked No.4, 5, and 9 respectively
• Canada ranked No. 8

The reason?
• Widespread awareness of the problem was relatively recent
• Costs of pollution were born externally
This is a classic free-rider problem.Remember?! I taught you the damn thing in Econ 328!
Dear Prof. Peter Ibbott
Also a Prisoner’s Dilemma…Consider two groups of countries facing the following choices:
1. Neither group adopts environmentally friendly policies (EFP). Outcome: all economies grow rapidly because no resources are diverted to pollution abatement or prevention; but a very bad environment.
2. Group A adopts EFP, Group B doesn’t. Outcome: Group A becomes disadvantaged in the global economic competition; but a better environment.
3. Group B adopts EFP, Group A doesn’t. Outcome: Group B becomes disadvantaged in the global economic competition; but a better environment.
4. Both groups adopt EFP. Outcome: no one is economically disadvantaged; the best environment among the four choices.
Solution…
• A coercive authority or a third-party organization, e.g. government and the UN
• Kyoto Protocol– To stabilize CO2 and five other Greenhouse
Gases concentration in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
Under Kyoto Protocol…
• Developed countries– Obligated to reduce GHG emission to a
certain level by 2012
• Developing countries (including China)– Do not have the obligation of emission
reduction
CO2 pollution in the near future…
• Not so optimistic:
• China has passed the EU and become the second largest CO2 emitter in the world
• China is building one coal-fired power plant every week (unsubstantiated)
• Not China’s fault? (yet to be evidenced)
The bright side…
• Initiatives have been taken:• Scientific perspective of development (科学发展观 ) by President Hu Jintao
• 30 environmental regulations & 375 environmental standards by central government
• Over 900 environmental standards by local governments
• 95,000 staff in 8,400 departments mobilized to monitor and enforce these regulations
Concluding remarks
• Al Gore in An Inconvenient Truth: “We got everything we need [to better our environment], save perhaps, political will…”
• A will to even sacrifice the current relative economic advantage
• The environmental issue is not an economic issue so much as a political issue
A better environment…
We hope that, with their excellence in leadership and
statesmanship, the political leaders in the world will make
this happen. And we’re counting on them.
