TRANSCRIPT

The Atmospheric Pollution and

the Economic Development in China

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

Fig 1: Share of world energy demand (1992)

Fig 2: Relative Severity of Air Pollution in Asian Sub-regions

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

Air quality in Asia’s mega-cities…

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)

In that study…

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

Fig 13: Historical Global Fossil Carbon Emissions

Fig 14: Carbon Dioxide Emissions by Country (1000 tonnnes)

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.

Fig 19: Kyoto Protocol Participation

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.

THE ENDTHANK YOU!
