Using 2005 constant prices
The accumulated amount of energy savings
2
amounted to 635 Mtce, while
fixed energy savings
3
amounted to 765 Mtce (see Table
2.3
, the difference of
accumulated energy-savings and fixed energy-savings could be shown in Fig.
2.8
).
Accumulated carbon reductions totaled 1.46 billion tons CO
2
, which made great
contributions for tackling global climate change and won widespread praise.
In terms of local environmental quality improvements, emissions of sulfur
dioxide decreased 14 % by the end of 11th FYP and the Chemical Oxygen Demand
(COD) COD decreased 10 % compared with 2005; which exceeded established
targets.
2.2
Quantitative Analysis of Energy-Savings Targets
Beijing launched an ambitious target of 20 % of energy-savings and pollution
reductions for the 11th FYP as a mandatory indicator for local governments.
The Chinese government has utilized command, law and economic measures to
promote energy conservation and efficiency improvements as well as pollution
reductions.
This section will evaluate the fulfillment of established energy-intensity and
pollution reduction indicators to sort out the factors of influence and analyze the
main contributors and roles of selected policies and actions to achieve energy and
environmental targets.
