Summary
According to IPCC report AR4:
Warming of the climate system is unequivocal, as is now
evident from observations of increases in global average
air and ocean temperatures, widespread melting of snow
and ice, and rising global mean sea level.
At continental, regional, and ocean basin scales,
numerous long-term changes in climate have been
observed. These include:
–
–
–
Changes in Arctic temperatures and ice,
Widespread changes in precipitation amounts, ocean salinity,
wind patterns
and aspects of extreme weather including droughts, heavy
precipitation, heat waves and the intensity of tropical cyclones
Changes in Precipitation, Increased Drought
• Significantly increased precipitation in eastern parts of
North and South America, northern Europe and northern
and central Asia.
• The frequency of heavy precipitation events has increased
over most land areas - consistent with warming and
increases of atmospheric water vapour
• Drying in the Sahel, the Mediterranean, southern Africa
and parts of southern Asia.
• More intense and longer droughts observed since the
1970s, particularly in the tropics and subtropics.

Administration, the climate in China:

Responsibility and burden sharing
Responsibility and burden sharing
• Responsibility: polluter pays, common and
differentiated responsibilities, based on
accumulated (effective) emissions, and
equity (per capita) principle;
• The Pew Center on Global Climate Change, an American think tank
close to progressive business, has made a proposal using a set of
three criteria to divide countries into three groups. These
criteria, standard of living, responsibility and opportunity,
consist, in turn, of different indicators.
• Responsibility for causing climate change is defined in terms of
countries’ historical and current total emissions, emissions per
capita and projected future emissions. Historical emissions are
defined as the cumulative CO2 emissions during the period 1950–
95. Estimated growth in emissions is extrapolated using the average
annual growth in emissions in 1992–95.
• Standard of living reflects the fact that in poor countries emissions
very often stem from an effort to meet basic necessities and that
richer nations are better equipped to cut down emission levels. The
indicator used for defining the standard of living is gross
domestic product (GDP) per capita.
• The opportunity criterion factors in the differences between
countries’ chances to reduce emissions. It is defined according to
the energy intensity of the economy, i.e. the amount of energy
that is used to produce a given economic unit of output.
• Finally, the Pew Center divides countries into three groups, or
tiers, according to these criteria.
– “Must Act Now” includes the majority of OECD countries, a few
transition economies, economically more prosperous southern nations
(e.g. Chile, Israel and Malaysia) as well as some oil-producing
countries, such as Kuwait, Saudi Arabia and Venezuela.
– “Should Act Now, But Differently” is comprised of the majority of the
transition economies, the rest of the western industrialised nations as
well as a good number of middle-income developing countries.
– The rest of the developing countries fall into “Could Act Now”.

Shanghai actions
The four key measures in the 2007 Implementation Plan:
– Re-form or restructure 3000 coal burning boilers and furnaces to save
200,000 tons of coal. To 2010, to reach energy saving capacity of 3 million
tons of coal and accumulated saving by 9 million tons of coal.
– Installing desulfurization device in 14 coal burning power plants;
wastewater collecting pipeline network in metropolitan area; the 3rd phase
construction; upgrading of ZhuYuan and BaiLongGang wastewater plants;
25 more wastewater plants; pipeline network for 30 wastewater plants; 28
industrial wastewater collecting pipeline network
– Optimizing power generation mode to replace electricity 2.3 billion kWh,
saving 200,000 coal; With public transportation priority (33%), completing
420 km subway/sky train system and 300 km pub-bus special line system;
New constructions should apply 50% energy saving standard of China and
to reach 65%; Energy saving reform/reconstructions on 30 million m2
building; and energy saving diagnostics for large scale (>3000 m2)
commercial buildings.
– Strengthening the management in key energy consumption enterprises,
e.g., by means of on-line monitoring, for reach over 95% pollutant
attainment discharges.

Shanghai actions
• In 2006~2009
– Shanghai energy intensity (energy consumption of unit GDP) has reduced
by 17.12%. It is of 84.14% of the target of Shanghai’s 11th Five-Year Plan.
In 2010, this index should be further reduced by 3.6%.
– SO2 and COD emissions have reduced in these four years by 26.1% and
19.9%, already reached the planned targets (26% and 15%).
• Renewable energy
– Wind power: On shore 24.4 MW (2008), Offshore wind power 100 MW
– Solar energy: Over 5MW at EXPO and Chongming Island, etc.
• EXPO2010:
– Solar power generation over 5MW, and 1000 new energy cars should
reduce carbon emission by 0.280 Mt
– Close up 800,000 kW small scale coal burning power plants; 500,000 sets
of energy saving air conditioners; 12 million energy saving lamps etc.
• Problem: during the first quarter of 2010, energy consumption was
increased by 16.96% in comparison of 2009. Electricity consumed by
16.79%, and the development trend of heavy industries is difficult to be
controlled.
For example:
Subway and sky trains
• London: 408 km
• New York: 370 km
• Tokyo: subway 286.2 km + trains ~ 1000 km
• Shanghai (2010) 420 km, to extend to 567 km in
2012 and 877 km in 2020 towards 1000 km

Observation
• Low carbon strategies
– Low carbon energy: wind, solar, geothermal, tide, and nuclear;
– Reduction of the scale of traditional industries;
– Industrial structure optimization: reducing high-carbon industries,
adding low carbon and carbon capturing industries
– Reducing energy consumption per unit production;
– Promote the development of CCS technologies.
• Questions
– Definition of “Low Carbon”?
– “Low Carbon” or “Lower Carbon”?
– Challenges in population growth and economic development;
• Difficulties
– Primary results of a comprehensive study reveals that the
40~45% reduction in relative emission may be reached, but it is
very difficult to reach the IPCC target for per capita emission
reduction, even CCS is included.
China carbon emission per capita increases quickly,
close to the global average
中国人均排放量迅速增加,接近世界平均水平
• China’s carbon emission is huge in the sense of annual total amount,
but compare with developed countries: 在年排放总量的意义上,中国碳
排放严重,但和发达国家比较:
– Accumulated total emission amount is still small; 累积排放总量小
– Per capita average emission is low;
人均碳排放量小
– Accumulated per capita emission is also low 累积人均碳排放量也小
• but, both annual emission and per capita emissions increase quickly;
但年排放量和人均排放量在迅速增加
• As a responsible nation, China is making efforts and committed 40~45%
emission reduction before 2020; 作为一个负责任的国家,中国已经承
诺在2020年前,见效碳排放强度40~45%
• Other measures…
China should also take serious actions
中国应当认真采取行动
• Developed countries are responsible for quantified GHG
emission reduction. China should also take actions. Before
the Copenhagen Accord, China committed to reduce
carbon emission intensity 40~45% by 2020 relative to 2005.
• 日本、美国、欧盟等发达国家和地区应当制定中长期绝对减
排目标。去年哥本哈根会议前夕,我国提出了“争取到2020
年单位国内生产总值CO2排放比2005年下降40%~45%”的自
愿减排目标。

Summary
• China looks at climate change seriously. Actions are
taken for adaptation and mitigation. However,
• The burden is heavy, the road is long:
– Population growth and urbanization;
– Economic growth;
– Improve energy structure;
– Phase out backward production capacities, and optimize
industrial structure;
– Develop alternative and renewable energies;
– Promote forestation for more carbon sinks;
– Rooms of emission reduction in building service, living
behavior, and transportation choices;
– International cooperation should be needed.
