I. Overall Air Quality in China
Compared with the year 2000, 22.2 percent
more cities of the country had air quality meeting Grade II
National Standard, and those with air quality worse than Grade III
standard dropped by 24.1 percent in 2005.
Of the 522 cities under national monitoring program in 2005, 319
were at or above prefecture level, and another 203 at county level.
22 of them enjoyed Grade I air quality, accounting for 4.2 percent;
293 met Grade II standard, taking up 56.1 percent; 152 met Grade
III standard, accounting for 29.1 percent; and 55 failed to meet
Grade III standard, taking up 10.6 percent. The major pollutant was
inhalable particulates. Compared with the previous year and among
the comparable cities, those with air quality at or better than
Grade II national standard increased by 12.6 percentage points, and
those failing to meet Grade III standard declined by 9.9 percentage
points. Therefore, the urban air quality witnessed certain
improvements.
In 2005, 357 out of the 696 cities (or counties) under national
acid rain monitoring program experienced acid rain, accounting for
51.3 percent of the total. Among others, Xiangshan County and Anji
County of Zhejiang Province, Shaowu City of Fujian Province, and
Ruijin City of Jiangxi Province suffered from 100 percent of acid
rain occurrences. In national acid rain control areas, the scope of
acid rain pollution was basically stable, while the pollution
degree increased to some extent.
II. Emissions of Major Air Pollutants in the
Country
Coal accounts for 70 percent of China's energy consumption. This
fact is hard to change in a short term. In terms of the coal use
method, 80 percent of the coal was for direct combustion. Among
others, coal-fired power plants burn 50 percent of the total coal
in China. Coal burning is the major source of ambient SO2, NOx, and
soot.
During the Tenth Five-Year Plan period, China's coal consumption
experienced an increase by more than 800 million tons, over 500
million tons of which went to thermal power industry. The year 2005
saw total emissions of SO2 at a high of 25.49 million tons and up
by 27 percent compared with that of 2000. The findings of relevant
studies have shown that about 20,000 yuan of economic losses
occurred with every ton of SO2 emission, and air pollution,
especially acid rain has significantly constrained the efforts in
achieving the goal of building a Xiaokang Society in an
all-round way.
In 2005, SO2 emission totaled at 25.493 million tons, including
21.684 million tons from industrial sources and 3.809 million tons
from domestic sources; the soot emission reached 11.825 million
tons, with industrial contribution of 9.489 million tons and
domestic share of 2.336 million tons; the emission of industrial
dust amounted to 9.112 million tons.
III. Prevention and Control of Air Pollution in
China
1. The desulfurization work has been carried out in thermal
power plants of China in an all round way. The end of 2000 had seen
only about 5 million kW of the installed capacity of
desulfurization facilities putting into operation, constituting 2
percent of the total installed capacity of thermal power plants. By
the end of 2005, however, there had been 142 desulfurization
projects, either completed or under construction, in major
in-service thermal power plants as stated in the Tenth Five-Year
Plan for the Two Controlled Zones, and 96.6 percent of those
projects had been started with a total installed capacity of
approximately 50 million kW. The installed capacity of established
desulfurization units nationwide had amounted to more than 76
million kW (including 30 million kW of Circulating Fluidized Bed
Boiler-CFBB), accounting for 20 percent of the total installed
capacity of thermal power plants with desulfurization capacity up
to over 2 million tons. The capacity of desulfurization facilities
that were under construction (including the contractual capacity of
the facilities yet to be started) had exceeded 200 million kW with
potential desulfurization capacity of 8 million tons/year. The
desulfurization work during the Tenth Five-Year Plan period had
significantly surpassed the target set in The Tenth Five-Year Plan
for Environmental Protection in Electric Power Industry, stating
that the installed capacity of desulfurization facilities shall
reach 15 million kW and 16 million kW under construction.
2. The prevention and control of pollution caused by vehicle
emissions has been under standardized regulation. State
Environmental Protection Administration (SEPA) has further enhanced
its supervision and regulation on new vehicles, in-service vehicles
as well as vehicle fuels, and released 15 groups of vehicle types
that meet national environmental protection standards in 2005.
National Phase II Motor Vehicle Emission Standards was put into
effect from July 1, 2005 in China, and the examination and approval
work for various vehicles (engines) that comply with National Phase
I Motor Vehicle Emission Standards was ceased. Meanwhile, SEPA took
active measures to promote low-sulfur fuels in China so as to
ensure smooth implementation of National Phase III Motor Vehicle
Emission Standards nationwide. In the end of December 2005, Beijing
took the lead in enforcing the National Phase III Motor Vehicle
Emission Standards as approved by the State Council.
3. The prevention and control of air pollution in Beijing has
yielded remarkable results. Beijing is implementing its 12th-stage
air pollution prevention and control measures. In 2005, Beijing
continued to strengthen the control of pollution caused by coal
combustion, finished the transformation of 249 coal-burning boilers
(with capacity less than 20 tons) with the application of clean
energy, and carried out desulfurization treatment to 81
coal-burning boilers (with the capacity more than 20 tons) from 27
units. Beijing has gradually upgraded its vehicle emission
standards, and began to supply fuels complying with National Phase
III Motor Vehicle Emission Standards from July 1, 2005. It has
enhanced the regulation of in-service vehicles, renewed or phased
out 28,000 outdated taxies and more than 3,900 old diesel-powered
buses. All the renewed vehicles met National Phase III Motor
Vehicle Emission Standards. Beijing authority has intensified the
regulation and supervision of a variety of construction sites,
strengthened the control of industrial pollution, and commenced the
efforts in relocating Shougang Group and stopped the operation of
Beijing Chemical Works. Thanks to a series of measures fighting air
pollution, Beijing has met the target of 63 percent of the days in
2005 meeting or better than Grade II national air quality
standards.
4. The proportion of clean energy has been raised to some
extent. The urban energy structure of China has experienced some
improvements. More than 20,000 boilers, large kitchen stoves and
residential cooking stoves in nine cities, including Beijing,
Tianjin and Chongqing, have utilized gas now instead of coal, and
the consumption of natural gas was up by nearly one fold. The
proportion of coal in the energy structure had dropped from 72
percent in 2000 to 66 percent in 2004. Accordingly, the above
cities saw significant improvement in ambient air quality. For
example, the concentration of inhalable particulates was down by 10
percent - 30 percent and the days with good air quality in 2004
increased by 10 to 40 percentage points compared with that of
2000.
5. More efforts are devoted to treating industrial pollution. A
number of outdated enterprises with heavy air pollution were closed
down through the adjustment of industrial structure. Take the
streamlining of calcium carbide, ferroalloy, and coke industries in
the bordering area of Shanxi, Shaanxi, Inner Mongolia and Ningxia
as an example, 185 enterprises not complying with industrial
policies were either banned or closed down in 2005, and 1.43
billion yuan was invested in dust removal and collection of 933
enterprises in compliance with industrial policies. For the time
being, 369 enterprises were permitted to operate after check and
acceptance, accounting for 39 percent; 264 were ordered to stop
operation for correction, taking up 28.3 percent; and about 300
enterprises were under natural production collapse due to market
factors, constituting 32.7 percent. The fact that those enterprises
were either closed down or stopped production has significantly
contributed to the improvement of regional ambient air quality.
IV. Air Pollution Control Measures in the Near
Future
1. To meet the target of controlling the total SO2 emission
under the 11th Five-Year Plan.
The Outline of the 11th Five-Year Plan for National Economic and
Social Development clearly states 10 percent reduction of
total SO2 emissions by 2010 as compared with the end of the Tenth
Five-Year Plan period, and the estimated total SO2 emission must be
under 22.95 million tons. This is a compulsory target. In order to
achieve this target, we shall do well the following tasks. First,
we will seriously develop the 11th Five-Year Plan for Prevention
and Control of SO2 and Acid Rain Pollution and try our best to make
it public this year after approval. Second, we will further put
into effect the requirements of the target responsibility system.
As entrusted by the State Council, SEPA has signed
target-responsibility documents on the control of total SO2
emissions with six largest electric power group corporations of
China, which emit more than 60 percent of SO2 and assume 75 percent
of emissions reduction target, as well as with the seven provinces
being key SO2 emission contributors. The next move is to sign
government responsibility documents with the rest 23 provinces,
autonomous regions and municipalities directly under the Central
Government. SEPA will release the performance progress of all
provinces and the six electric power group corporations every six
months, report to the State Council on the assessment results and
make them to the public. Third, SEPA will conduct pilot projects on
paid acquirements of SO2 emission right and emission trading, and
achieve the best emission reduction effects at the minimum
treatment cost by making full use of market mechanism in allocating
resources. Fourth, SEPA will intensify the supervision and
management on desulfurization facilities in thermal power plants.
At present, desulfurization work is under rapid development. We
shall enhance the supervision and management of companies engaged
in desulfurization projects, carry out whole-process monitoring on
the construction projects, do well the check and acceptance work,
and strengthen the supervision and regulation of desulfurization
facilities already put into operation, so as to ensure normal and
stable operation of those facilities.
2. To enhance the prevention and control of industrial
pollution
We will, by seizing the favorable opportunity of cutting down
overcapacity, rigorously implement The Notice of the State Council
on Facilitating the Restructuring of Industries with Overcapacity,
raise the access conditions for environmental protection, release
public notice on the name of enterprises meeting the target, and
forcefully phase out outdated production process, technology,
equipment and products that waste resources and cause heavy
pollution.
3. To control pollution caused by motor vehicle emissions
strictly.
We will develop and improve the laws, regulations and standards
on the prevention and control of pollution caused by vehicle
emissions, gradually upgrade the emission standards of new
vehicles, make more efforts in phasing out old and outdated
vehicles, and resolutely control the increasing trend of total
amount of vehicle emissions year by year.
4. To make in-depth efforts in comprehensive prevention and
control of urban air pollution
Firstly, we will improve energy structure and treat non-point
pollution. Secondly, we will intensify the prevention and control
of secondary dust in cities. Thirdly, we will improve the
calculation method for urban environmental capacity in order to
provide a scientific basis for the control of urban atmospheric
environment. Fourthly, we will carry out the ambient air quality
releasing system, issue relevant information on the assessment of
urban air quality on a regular basis, and release timely
information about pollution accidents if any.
