Title: Urban Air Quality and its Management in China, P'R'


1
Urban Air Quality and its Management in China,
P.R.
  • LI Xinmin
  • State Environmental Protection Administration
  • 27 September 2006

2
Environmental pollution not radically controlled
  • The total SO2 emission was 25.49 million tons in
    2005, up 27 compared to 2000
  • 40 of the 522 cities were lower than the Grade
    II of NAAQS There was not even one city
    compliant to Grade II of NAAQS in Shanxi
    Province.
  • Acid rain occurred in more than half of the 696
    cities and counties

3
Energy
  • Coal is the primary energy source in PRC and its
    consumption is expected to continue to increase
    from 1.3 billion tons in 2000 to between 2.1 and
    2.9 billion tons in 2020 dominating more than 50
    of primary energy share until 2020
  • Petroleum/Crude Oil will account for about 27 of
    total primary energy in 2020

Registered Motor Vehicles in China, P.R.
  • Ownership of automobiles and motorcycles has
    exceeded 43 million and 94 million respectively
    by the end of 2005 registering an increase of
    20.6 for cars and 23.6 for motorcycles compared
    in 2004

Rapid Increase in Electric Bicycles
  • Electric bikes are gaining an increasing share of
    two-wheeled transportation in P.R. China
  • Defined as special two-wheel bike motivated by
    both manpower and electrical power, using storage
    battery as supplementary power
  • Annual electric bike sales in P.R. China grew
    from 40,000 in 1998 to 10 million in 2005
  • Dramatic growth has been largely due to
    legislations banning gasoline-fuelled scooters
    and bicycles, introduced from 1996 onwards in
    several major Chinese cities, including Beijing
    and Shanghai

8
Emissions Inventories
  • SEPA regularly conducts regular emissions
    inventories
  • SO2 increased steadily from the 1990s to the 1995
    but slowly dipped again from 1995 to 1999, after
    which they started to increase again
  • For 2004, the total SO2 emissions reported by
    State Environmental Protection Administration
    (SEPA) were about 22.5Mt.
  • Nitrogen oxide emissions have increased
    consistently and in 2003 were almost twice the
    1990 emissions.
  • Smoke dust and industrial dust on the other hand
    have shown decreasing trends since 1997

9
National Acid Deposition and
SO2 Pollution Status
The area of acid rain was stable in 2005, but the
frequency was increased. The acid intensity was
increased in acid rain zone. Generally, acid rain
pollution was aggravated. P.R. China SO2
emissions are concentrated mostly in the Central
and East coastal areas - area with heavy
industries. 58.3 of the cities in Central China
experienced acid rain with 21.4 experiencing
occurrence of over 80

10
Acid Deposition Zones
  • Six serious acid deposition zones
  • Southwest
  • Pearl River Delta
  • Yangtze River Delta
  • Huai Sea zone
  • Big Beijing zone
  • Three West zone (Shanxi, Shaanxi and Inner
    Mongolia).
  • The acid deposition is much higher than the
    environmental capacity in these areas.

11
Air quality challenges from the power sector in
the 11th Five-Year Plan period
  • In 2005, the national power generation capacity
    was 512 million kw, of which thermal power was
    389 million kw. It is expected that the new built
    thermal power generation capacity will be 72
    million kw in 2006.
  • The new built power generation capacity will
    reach 300 million kw by 2010 and the total power
    generation capacity will reach 818 million kw
    with an annual growth rate of 9.8.
  • The coal consumption in 2005 was 2.1 billion
    tons, of which 0.93 billion tons were consumed
    for power generation. The SO2 emission in 2005
    was 25.495 million tons, of which 13 million tons
    were emitted by power sector.
  • Coal consumption in 2006 will be around 2.2
    billion tons and produced SO2 amount will be
    around 29.5 million tons.
  • Coal consumption in 2010 will be around 2.5
    billion tons, of which 1.68 billion tons will be
    consumed for power generation, and produced SO2
    amount will be around 43.49 million tons, of
    which 23.6 million tons will be produced by power
    sector.

12
Main Causes Environmental Problems caused by coal
fired power plants (1)
  • Low efficiency and high emission
  • The national average unit coal
    consumption of power generation is 374g/kw.h in
    2005, much higher than the international advanced
    level of 5060g/kw.h
  • Coal is rich in north and west and lack in south
    and east.
  • The east area consumes 55 the national total
    electricity but only holds 10 of the national
    total coal resource.
  • The environmental capacity and electricity demand
    dont match.
  • The power generation capacity of east
    area contributes to 54 of the national total
    while the environmental capacity is limited the
    west area is affluent in resources and
    environmental capacity while the power generation
    capacity is less.

13
Main Causes Environmental Problems caused by coal
fired power plants (2)
  • Unreasonable structure of electricity sources
    hydropower generation capacity is more than 0.1
    billion kw while the proportion to total power is
    only 25. Nuclear power generation capacity is
    6.85 million kw, accounting for 1.34 of the
    national total, much lower than the international
    average level of 10. Electricity generated from
    new energy such as sun energy only contributes
    0.24 of the national total, much lower than the
    international average level of 1.
  • Small thermal power units operational again
    These units have energy efficiency as low as
    700g/kw.h and are uneconomical for installation
    of desulfurization facilities.
  • The quality of coal is getting worse lower heat
    value, higher ash and sulfur content

Forecast of NOx Increase Trend
Comparison of NOx Emission Inventories for 2010
and 2020 by sector
16
Main Causes for AQ Problems
  • Rapid development of heavy chemical industry,
    prominent structural pollution, unreasonable
    industrial structure
  • High energy consumption, increase of 2 billion
    tons of coal and 0.4 billion tons of petroleum
    consumed in 2000-2005 compared to 1995-2000
  • Rapid motorization
  • Extensive economic development pattern, high
    growth paid by high cost
  • Weak awareness on environmental regulation,
    unsound legal system, slack enforcement, low cost
    of violation, and high cost of compliance.
  • Environmental protection issue separated from
    decision making

17
Air Quality Monitoring
  • There are 2,289 monitoring stations in the
    country that employ more than 45,849 personnel to
    conduct monitoring work
  • The governments five-year plan for ambient air
    quality monitoring for all cities directly under
    a province required the establishment of an urban
    automatic ambient air monitoring system as well
    as an urban acid rain monitoring system for all
    cities by 2005
  • As of June 2004, there were 688 automatic air
    quality monitoring units in place in 234 cities
  • In 2004, there were 527 cities able to monitor
    acid rain occurrences
  • For dust and sandstorms monitoring, the National
    Meteorological Bureau of China has set up six
    special sandstorm monitoring stations equipped
    with automatic devices at the source and along
    major routes of sandstorms in North Chinas Inner
    Mongolia as part of the Sandstorm Project of
    the SEPA

18
PRC National Ambient Air Quality Standards
compared with WHO and US
Chinese cities are required to comply with
Class II NAAQS
19
Status of Air Quality API trends
  • The share of the population living in cities
    meeting the NAAQS accounted for 33.1 of the
    total in 2004, decreasing by 3.3 compared with
    2003
  • Decrease in percentage of cities with air quality
    worse than class 3 of NAAQS from 40.5 in 1999 to
    20.3 in 2004 and the increase of cities
    complying with Class 2 (from 33.1 in 1999 to
    38.6 in 2004) and Class 3 (from 26.3 in 1999 to
    41.2 in 2004) of the NAAQS

23
Air Quality Management Policies (1)
  • The Environmental Protection Law (EPL) of PRC
    adopted in 1989 is the countrys primary law that
    provides the legal framework for the prevention
    and control of pollution
  • In 1987 the Prevention and Control of Atmospheric
    Pollution Law (LPCAP) was created and later
    updated in 1995 and in 2000
  • SEPA under the State Council conducts unified
    supervision and management of environmental
    protection throughout the country
  • SEPAs local counterparts are the Environmental
    Protection Bureaus (EPBs) or offices (EPOs) and
    they administer, supervise, and manage
    environmental protection activities at the
    provincial, municipal, county, and district level

24
Air Quality Management Policies (2)
  • Within SEPA the primary responsibility for urban
    air quality managements rests with the Pollution
    Control Department
  • PCD can call upon the assistance of the National
    Environmental Monitoring Centre, the Chinese
    Research Academy for Environmental Sciences, and
    other specialized institutions
  • Air quality management capabilities of Chinese
    cities vary strongly
  • The capacity of cities in the coastal belt is
    better developed than those in the Western cities
  • Several cities either have received or are still
    receiving assistance from bilateral development
    agencies to strengthen their air quality
    management systems

  • P.R. China is at the forefront in
    institutionalizing vehicle emissions standards in
    developing countries in Asia
  • In addition to Beijing, Guangzhou has adopted the
    Phase III (Euro III equivalent standards) and
    Shanghai has already requested for approval from
    the State Council

  • Fuel Consumption Limits for Light Duty Passenger
    Vehicles were published on September 2, 2004 and
    implemented in July 2005 P.R. China became the
    first Asian country to implement such standards
  • The first phase of the standard targeting a
    reduction of 5 in per-distance fuel consumption
    was implemented in 2005, and a second phase, with
    a goal of 10 reduction in fuel consumption for
    each weight category in 2008
  • It is forecasted that 13 million tons of fuel
    will be saved in 2020 and 31 million tons in 2030

27
Air Quality Management Policies Mobile
Sources (3)
  • The 11th Five-Year Plan of P.R. China will
    prioritize the development of public
    transportation with mass rapid transit (MRT) as a
    key transport mode in mega cities and the NRDC
    has issued guidelines for implementation with the
    following provisions
  • Develop BRT system
  • Public transportation enterprises should increase
    the bus density, choose safe, energy-efficient
    and environment-friendly buses and scrap the
    high-polluting and low-technology buses
  • The governmental fund to be used in urban
    transportation construction shall favor public
    transportation and cities should implement
    economic subsidy and compensation policy for the
    public transportation
  • The price of public transportation should pay
    attention to both economic benefits and social
    benefits, and the business cost of the
    enterprises and the paying capacity of the public

28
Air Quality Management Policies
Stationary Sources (1)
  • P.R. China's emission standards for stationary
    sources relating to air pollutants can be divided
    into two categories (1) those for particular
    industries or particular types of pollution and
    (2) general standards specified in the Integrated
    Emission Standard of Air Pollutants (IESAP).
  • Stationary sources are classified as boilers,
    thermal power plants, industrial kilns and
    furnaces, coke ovens and cement plants and are
    required to comply with the corresponding
    emissions standards
  • The IESAP was enacted in 1996 and came into
    effect in 1997, it prescribes two sets of
    emission limits, one for new facilities installed
    on or after January 1, 1997, and another set for
    existing facilities installed prior to that date

29
Air Quality Management Policies
Stationary Sources - SO2 Control (2)
  • In the 11th Five-year plan, SO2 emission
    reduction is the emphasis of air pollution
    prevention and control and states that the
    emissions of sulfur dioxide should be reduced by
    10 by 2010
  • The three principal components of existing SO2
    emissions control policy are the Pollution Levy
    System (PLS), Two Control Areas (TCA), and Total
    Emissions Control (TEC)
  • PLS is based on the polluter pays principle
  • TCA is not an instrument like the pollution levy
    for affecting abatement behavior, but rather a
    means for prioritizing SO2 control efforts,
    designating the standards, and identifying cities
    and regions that should receive extra attention
    and resources from the national government
  • TEC limits the polluters to discharge under a
    specified level and levies the charge when any
    pollution is discharged
  • Planning for the future
  • Keep implementing the Total Emission Control
    systems
  • Estimation of environmental capacity
  • Set reduction goals for east, middle part and
    west
  • Separate the emission reduction goal of power
    sector from the overall goal
  • The high pollution sources controlled by the
    state
  • Measuring the performance by emission per unit
    power generation
  • Strengthening the construction of automatic
    on-line monitoring network

30
Air Quality Management Policies
Area Sources Dust and Sandstorms
  • The Chinese government ratified the UN Convention
    to Combat Desertification (CCD) in December 1996
  • As a follow-up, the China National Committee to
    Implement the UN CCD (CCICCD) was set up and a
    China National Action Program (NAP) to Combat
    Desertification was prepared
  • Government also earmarked CNY54 billion (about
    6.5 billion) for a 10-year program to address
    the DSS concern in the northern PRC

31
Conclusions and challenges ahead (1)
  • Trends of APIs from 1999 to 2004 suggest that air
    quality in Chinese cities is generally improving
    and confirmed by the percentage increase of
    cities complying with Class 2 (from 33.1 in 1999
    to 38.6 in 2004).
  • However, the actual ambient air quality levels
    for PM10, SO2, and NO2, though generally
    improving are still above the WHO guidelines
  • For the future the days of above grade II of
    NAQQS in 65 of the key cities gt 292
  • To meet the air quality goals for the coming
    years, improvements will need to be made in
  • the monitoring of air quality
  • the capacity to develop and implement air quality
    management plans
  • the coordination at the national and local level
    among relevant bureaus and agencies at different
    levels of government in implementing and
    developing AQM

32
Conclusions and challenges ahead (2)
  • The SO2 control policy in the 11th Five-Year Plan
    of the government is very timely because in this
    same period coal use in P.R. China is expected to
    increase as demand for energy also increases
  • The national emission of SO2 reduced by 10
  • Total SO2 emission lt 22.94 million tons
  • SO2 emitted by power sector lt 10 million tons
  • Regarding SO2, the energy consumption in 2010
    will reach 3 billion tons of standard coal and
    the raw coal consumption will be around 2.8
    billion tons, emitting SO2 by 43 million tons. To
    achieve the SO2 emission goal of 22.94 million
    tons, the SO2 reduction shouldnt be lower than
    20 million tons while the current treatment of
    SO2 is only 9.5 million tons. This means that
    capacity to reduce another 10.5 million tons
    needs to be created.
  • The intensity and frequency of acid rain should
    be mitigated

33
Conclusions and challenges ahead (3)
  • Promoting environmental protection by resource
    conservation. The energy consumption per unit GDP
    should be reduced by 20. If the resource
    conservation goal cant be realized, it is almost
    impossible to fulfill the emission reduction
    goal.
  • Investing more in pollution control. The total
    investment for environmental pollution control
    during the 11th Five-year Plan period is 1.3
    trillion yuan. The annual investment demand is
    260 billion yuan, accounting for a little higher
    than 1.

34
Conclusions and challenges ahead (4)
  • Strictly implementing relevant laws and
    regulations
  • Build larger capacity for AQM at the national,
    provincial and local levels
  • Integrating environmental protection index into
    the governmental performance evaluation system
    and ensure clear responsibilities at various
    governmental levels
  • Promoting purchase of SO2 emission permit and
    emission trading pilot projects
  • Fully implementing emission permit system and
    promoting market based approaches to pollution
    control.

35
Conclusions and challenges ahead (5)
  • Great efforts should be made for control of
    particulate matter, especially fine particles.
  • The removal of industrial pollution sources in
    urban areas through scrapping of low and small
    pollution sources should be sped up.
  • The energy efficiency and the rate of clean
    energy should be increased by developing combined
    heating supply and power generation, centralized
    heating, setting high-polluting fuels forbidden
    zones, etc.
  • The pre-warning system of photochemical smog
    pollution needs to be established.
  • Add new power generation capacity with
    desulfurization facilities by 100 million kw and
    146 million kw by the end of the period,
    installing desulfurization facilities for all of
    the newly built power generation units, not
    allowing building of new coal-fired power plants
    in large or mid-sized cities and their near
    suburbs or the areas where the acid rain
    pollution is serious or the SO2 concentration is
    higher than the standard.
  • Strengthening the air pollution prevention and
    control for industries.

36
Conclusions and challenges ahead (6)
  • Vehicle emission control needs to be enhanced to
    deal with the rapid increase of numbers of
    vehicles
  • Fuel road map needs to be developed leading up to
    Euro 4 for all regions of the country
  • In-use vehicle emission strategy needs to be
    developed which addresses gross polluting
    vehicles including strengthening of I/M systems
  • Policy on motorcycles to be developed to ensure
    that emissions from these type of vehicles are
    reduced
