potential of these technologies is great. To encourage research and disseminate these
advanced energy saving and emissions reduction technologies, the government has
set out a series of policies and incentives that could stimulate the market and create
favorable conditions for their adoption in high energy-consuming industries during
the 12th Five-Year Plan period.
There has been some research analyzing the energy saving and emissions
reduction potential of the adoption of energy-efficiency improving technologies

that are technically and economically feasible for the Chinese market. In the next
decade, if just 80 of these technologies prevail in the high energy-consuming
industrial sectors, the annual energy saving capacity could add up to an
accumulated 0.46 billion tons of coal equivalent by 2020, with a corresponding
annual carbon dioxide emissions reduction capacity of 1.07 billion tons of coal
equivalent. If all the available technologies (including current and emerging) are
adopted in time by the industrial sector, then in 2020 the annual energy saving
capacity is estimated to be above 0.6 billion tons of coal equivalent, with a carbon
dioxide emissions reduction capacity of 1.5 billion tons of coal equivalent.

Commercial and Civil Sector
At the turn of the new century, increasing urbanization led to about 15 million rural
laborersmigrating to cities every year, leading to extensions of about 1.5 billion square
meters to existent buildings and more than 2 billion square meters of new buildings.
Meanwhile, since 2000, an increase in living standards in both rural and urban
areas has led to an average growth of 7-29 % every year in the amount of household
electrical appliances in homes [

].
Due to the increasing amount of commercial buildings like office space, hotels
and shopping malls, and expanding AC energy demand, venting, light and hot
water, it is thought by some institutions and experts that energy consumption for
commercial and civil use accounts for 15.3 % of total energy consumption, and the
figure is growing rapidly. Therefore, the effects of energy conservation in the
commercial and civil sectors will have a direct bearing on achieving the goals set
in the 11th Five-Year Plan and pose a great impact on energy saving and emissions
reduction targets in the 12th Five-Year Plan period, or in the long term.

Among the current 80 major industrial energy-efficiency improving technologies, 19 apply to the
electric power industry (four are advanced thermal power generation technology), 11 for the steel
industry, 15 for the construction material industry, 17 for the petrochemical industry, nine for the
nonferrous metal industry, five for the textile industry, and four for the papermaking industry.
