Source: Author compiled this data based on publicly available data
conducted in 2009. The draft law combines the current methods of preventing and
controlling air pollution with new forms of management. The government is
increasing controls on the total amount of emissions as well as overhauling the
management and discipline system for pollutant emissions permissions and motor
vehicles. In December 30th, 2009, the standing conference of China's environmen-
tal protection department reviewed and approved the draft in principle and submit-
ted it to the State Council.
Desulfurization
In recent years, the Chinese government has paid attention to the unprecedented
levels of sulfur dioxide emissions and put forth regulations, especially for the
thermal power industry, which accounts for 40-50 % of sulfur dioxide emissions.
Through the implementation of the desulfurization electric policies, the desulfuri-
zation project has achieved results in terms of meeting emissions reduction targets.
During the 11th Five-Year Plan period, a 500-million-megawatt coal-fired power
plant desulfurization facility was built and is currently running, and the percentage
of Chinese thermal power plants with desulfurization units has increased from 12 %
in 2005 to 80 % [ 5 ]. The installed capacity of desulfurization facilities within coal-
fired power plants has seen a tenfold increase over the course of the last Five-Year
Plan. The reduction of outdated industrial capacity has reached an unprecedented
level, and small-scale power generation facilities that produce a combined total of
7 MW have been eliminated (Table 6.2 ).
The data shows that in 2009 the thermal power coal consumption in China was
reduced to 340 g/kW-h, closing the gap with the world's advanced countries. The
loss rate of the national power grid line is 6.72 %, also close to the international
advanced level. The rate of installation of national coal desulfurization facilities
reached 76 %, with a sulfur dioxide emissions capacity per unit of 3.2 g/kW-h.
Through the use of structural, technological and administrative means, the sulfur
dioxide emissions of electricity power has dropped to about 9.4 million tons, a
decrease of 29.3 %. This means China hit the goal set out in the 11th Five-Year Plan
of reducing sulfur dioxide emissions to 9.52 million tons a year in advance.
