6Why is there no clear pattern?
- Regulation comes in waves
- Growth uneven
- Decentralization
- Relative prices, e.g., coal
- Short time horizon
7Statistical reporting
- Falling levels of NOx, SO2, TSP in 11 major
cities - Contrasts starkly with bleak qualitative reports
- What information is needed to complete story?
8Towards improved statistical reporting
- TSP measurement PM 40 vs PM 10
- NOx measurement NO vs NO2
- Decentralization of industry?
- All emissions are not equal need
source-receptor modeling
9Towards improved statistical reporting cont
- Sampling protocols location, seasonal, weather
factors (Beijing TSP falling, but May 2000,
then Premier Zhu Rongji warned that the rapidly
advancing desert would necessitate moving the
capital from Beijing - Season matters In Beijing, winter SO2 2.7 times
worse for health than average SO2, and 14.2 times
worse than summer SO2 (Brajer and Mead 2004)
10But with more careful analysis
- Auffhammer et al. (2004) CO2 in 30 provinces
from 1985-2000 - Correct approach is effect of income with
controls on composition of industry, population,
and proximity to the coast - China on the flat part of EKC
- Income not as important for CO2 concentrations as
population growth
11Water pollution
12Concentrations
- Proportion in poor water classes decreasing, but
concentrations increasing
13Natural Resources Water
- Water resources not increasing supply (raw
provision of water to consumers, including
transportation loss, from the water resource)
decreasing - 246.826 million people without running water
- Problem especially severe in populous northern
cities, water scarce, pollution severe, low
income households with no running water
14- people are found boiling black water and
scraping off the scum that accumulates on the top

15Soil
- Desertification 900 square miles, 5 billion tons
lost/yr. (Brown, 1994) - Since the 1990s, desertification has been major
land resource concern - But, productivity quantity farmland increasing,
140 million hectares in 1993 (Lindert, 1996) - Soil movement not soil loss
- Increased food imports reflect changing
comparative advantage. - Off-site problems, health effects may be of
greater concern
16Forests
17Forests cont
- Total area increasing, total volume rebounding
(Rozelle et al. 2003) but quality, biodiversity
decreasing - Afforestation campaigns fast growing species,
overly dense spacing problems with species
viability, commercial value, biodiversity.
18Fisheries
Source Chinese Academy of Fishery Sciences
19Fisheries
- Largest producer in the world, largest number of
fishing boats - Over-fishing, water pollution
- gt decline in stocks
- Regulations in place to limit number of boats but
not quotas - Quotas considered (not ITQs)
20Energy
21Coal
22Energy cont.
- Oil cleaner, less construction time
- Coal consumption still growing especially after
2000 (relative energy cost, import prices) - 2nd largest exporter of coal beginning 2001
23Depreciation of Natural Capital
- Air pollution growth less than GDP
- Water pollution not greater than GDP
- Renewables decrease in stock reduction
- Non-renewablesextraction growing less than GDP
24GNNP
- Constant or decreasing wedge
- Opportunities for further convergence, i.e.higher
growth
25Policy Reform
- Inconsistent regulations across industries and
firm sizes - Weak incentives small fines, no incentives for
inspectors - Lack of enforcement comply only during
inspections, not enough inspectors - Underpricing of natural resources
26Improvements?
- Water prices going up in some areas
- Experimentation with tradable sulfur permits
27Remaining Challenges
- More attention to air than water pollution
- Need for water demand management
- Water, forestry resources remain underpriced,
overused - Use of oil has increased, but not as fast as
energy consumption - Major roadblock appears to be public
administration
28Conclusions
- Substantial progress in energy efficiency and
emissions/BTU - Offset by rapid growth and low per capita income,
i.e. EKC max remains in future - Growth statistics not compromised by failure to
deduct environmental depreciation
