comparability. The system can reflect the status and trends of emissions of major
pollutants in a timely, accurate and comprehensive manner.
The major characteristics of an accurate emissions monitoring system are:
advanced equipment, normative standards, diverse tools and efficient operation.
This system enables managers to track the changes to the environmental situa-
tion in different regions.
The strict emissions-reduction inspection system involves clear responsi-
bilities, effective supervision, appropriate procedures as well as clear penalties
and rewards. This ensures that those who continue to ignore pollution reduction
responsibilities pay a certain price.
4. The nine institutions refer to: examination, statistics, monitoring, verification,
scheduling, direct reporting, recording, information disclosure and reprimand.
These institutions are aimed at motivating enterprises to meet environmental
goals and ensuring the continual progress of emissions reduction. To ensure
the credibility of emissions data, the Ministry of Environmental Protection
organizes inspections around twice a year, and its policy states that local
emission results are only to be published after verification by the Ministry of
Environmental Protection [ 2 ].

Air Pollution Control During the 11th Five-Year Plan
6.3.1 Air Pollution Prevention Compliance Rate During
the 11th Five-Year Plan
From Fig. 6.1 we can see that the development of the economy and the growth of the
economic output have led to a subsequent increase in industrial emissions. Thanks
to national regulations and the expansion of investments in environmental protec-
tion, the growth rate of emissions has slowed in recent years. The rate of compliance
with restrictions on industrial waste gas emissions has continued to increase since
2001 and has reached more than 90 %. However, it still needs to be improved.
According to environmental monitoring results, the density of pollutants in
the atmosphere has decreased every year since the start of the 11th Five-Year
Plan period, and great strides have been made in the mitigation of industrial gas
pollution [ 3 ]. At the same time, the air quality of key cities has improved year by
year, and the comprehensive improvement of the urban atmospheric environment is
obvious. In 2010, the annual density of sulfur dioxide of the air environment in
cities dropped 24 % compared to 2005. The annual density of sulfur dioxide of the
air environment in the key environmental protection cities dropped 26.3 % com-
pared to 2005 levels. The rate of cities administered at the local level or higher that
achieved or exceeded the secondary standard of air quality has gone up consider-
ably, reaching a total of 85.0 %.
The sulfur dioxide emissions for all of China in 2010 totaled 21.85 million tons,
soot emissions hit 8.29 million tons, and industrial dust emissions, 4.48 million
tons, marking declines of 1.3 %, 2.2 %, and 14.3 %, respectively, compared to 2009.
In 2010, 417 cities in China conducted environmental air quality monitoring.
