Abstract
and drawn from relevant materials on the websites of the National Development and
Reform Commission and the Ministry of Environmental Protection
Effects of Emission Reduction: based on a report of the National Development
and Reform Commission (on March 10, 2011 of Xinhua net), the achievements of
energy saving and emission reduction are as follows:
1. Strongly bolster the stable and rapid development of the national economy.
During the 11th Five-Year Plan, the national economy increased by 11.2 %
annually with only an annual 6.6 % increase in energy consumption. The
elasticity coefficient of energy consumption decreased from 1.04 during the
11th Five-Year Plan to 0.59, relieving the imbalance between supply and
demand of energy.
2. Reverse the rising trend of energy intensity and pollutant emissions during the
process of industrialization and urbanization. During the period of the 11th Five-
Year Plan, the national energy/GDP ratio fell by 19.1 %, and total emissions of
SO
2
and chemical oxygen demand declined by 14.29 % and 12.45 %
respectively.
3. Promote the Optimization and Updating of the Industrial Structure. Advanced
production capacity of key industries rose conspicuously, and large and highly
efficient equipments were popularized and applied. Comparing 2009 to 2005, in
the power industry the proportion of thermal power units with over 300 MW of
installed capacity rose from 47 % to 69 %, in the steel industry the share of large
blast furnaces over 1,000 m

increased from 21 % to 34 %, in the electrolytic
