  • World energy dramatic consumption increase…


  • …that cause serious consequences.


  • How can we reduce the energy consumption ?


  • Right approach : China Saving Energy Stiffer Law 严格 法律


    • Standing Committee of China's National People's Congress (NPC), the country's top legislature, has voted to adopt revisions to the Environmental Protection Law, enshrining environmental protection as the government's overriding priority, with specific articles and provisions on smog.
    • For the first time, the law has established clear requirements for ecological protection.

  • One solution : Saving Energy in Building 大楼 节约能源


    • In a typical European household, well over half the money spent on fuel bills goes towards providing heating and hot water, so it makes sense to invest in the most energy-efficient heating system.
    • So the main sector of energy savings is found in the housing communities.

  • Concrete example : Housing Saving Energy (Tianjin 天津)


    • Location : Bīnhǎi Xīn Qū (滨海新区)
    • Building, 40 floors, 30 000 m2
    • Concern Equipment : Heating or Air Conditioning
    • Estimated investment cost : $ 10,000
    • Return on investment : 13 months
    • Estimated 3 years Energy savings : $ 50,000
    • White certificate earning : $ 3,500

  • Example : Boilers Saving Energy China Potential Market


    Considering surface of more than 5000 m2 :
    • 12 millions of device today in activity has to be checked.
    • 25 % has to be replaced.
    • 75 % has to be rejuvenated through a saving energy device.
    • China boilers with saving energy device implementation market is estimated to a level of 24 billions of yuans (2,3 Md US$).

  • Chaoyang Saving Energy Plan 節能 计划朝阳区 節能 计划


    What could be for the 5 years to come a plan to slash the energy consumption and to reduce the CO2 emission in the Cháoyáng Qū ?
    A triple project target
    • A reduction of the pollution and the emission of CO2
    • Inhabitants of buildings will save money on their energy bill
    • The Municipality will get to a new source of income

  • Chaoyang Estimates Saving Energy Plan

  • Saving Energy means Saving Money for your properties ! 节省


    How to save money and add value to your real estate through an ecological way ?
    5 five ways to do it !
    In Europe :
    (1) For the housing building equipped with saving energy devices, the market rental values, yields and acquisition prices have steadily increased :
    • 2011 : + 3 %
    • 2012 : + 2,7 %
    • 2013 : + 2,6 %
    (2) Those ones that haven’t such equipment have experienced a sharp decrease that intensified over the years :
    • 2011 : - 2 %
    • 2012 : - 2,6 %
    • 2013 : - 4,7 %

  • Europe Saving Energy Plan


    (1) In Europe, residential building consumption represents 45 % of the total energy cost (2013).
    This is the main sector of energy savings.
    (2) Under the Renewable Energy Directive 2012/0288 (COD), the EU aims to get 20% of its energy from renewable sources by 2020.

  • Carbon Trading : The White Certificate


    • A white certificate, also referred to as an Energy Savings Certificate (ESC), is an instrument issued by an authorized body guaranteeing that a specified amount of energy savings has been achieved.
    • The white certificates are given to the producers whenever an amount of energy is saved whereupon the producer can use the certificate for their own target compliance or can be sold to (other) parties who cannot meet their targets.
    • Each certificate is a unique and traceable commodity carrying a property right over a certain amount of additional energy savings and guaranteeing that the benefit of these savings has not been accounted for elsewhere.

China rivers



China abounds in rivers. More than 1,500 rivers each drain 1,000 sq km or larger areas. More than 2,700 billion cu m of water flow along these rivers, 5.8 percent of the world’s total.

China’s rivers can be categorized as exterior and interior systems.

The catchment area for the exterior rivers that empty into the oceans accounts for 64 percent of the country’s total land area. The Yangtze, Yellow, Heilongjiang, Pearl, Liaohe, Haihe, Huaihe and Lancang rivers flow east, and empty into the Pacific Ocean.

The Yarlungzangbo River in Tibet, which flows first east and then south into the Indian Ocean, boasts the Grand Yarlungzangbo Canyon, the largest canyon in the world, 504.6 km long and 6,009 m deep. The Ertix River flows from the Xinjiang Uygur Autonomous Region to the Arctic Ocean. The catchment area for the interior rivers that flow into inland lakes or disappear into deserts or salt marshes makes up 36 percent of China’s total land area. Its 2,179 km make the Tarim River in southern Xinjiang China’s longest interior river.




The pollution was severe in Liao and Hai River Basins, and the water quality of its tributaries and at interfaces between provinces was more severe. The water quality in Yellow River Basin was relatively bad in general. The water quality of Pearl River Basin was good in general. The water quality of the mainstream and the immediate tributaries of the Yangtze River were good. The order of seriousness of pollution of the seven main river basins was Hai River, Liao River, Yellow River, Huai River, Songhua River, Pearl River and Yangtze River.

Today, more than 450 million people depend on the two longest rivers–the Huang (Yellow) and the Yangtze–for water, agriculture, fishing, and other uses. But over the past 20 years, water quality in these rivers has deteriorated to a grave state.

According to the 2013 World Bank report China: Air, Land, and Water–Environmental Priorities for a New Millennium, significant stretches of the two river ways are classified as unsuitable for human contact by the Chinese State Environmental Protection Administration. And according to the central government’s 1996 report on the state of the environment, 40% of the monitored sections of all rivers flowing past cities did not meet China’s minimum water quality standards.

The major pollution indicators were petroleum, BOD, ammonia nitrogen, permanganate index, volatile phenols and mercury.




SEPA and Ministry of Supervision jointly organized the supervision departments from 12 ministries and commissions under the State Council to conduct a comprehensive inspection on the implementation of the plan.
Formulation of the Tenth Five-Year-Plan for Prevention and Control of Water Pollution in Huai River, Hai River, Liao River, Lake Chao and Dianchi Lake Area.
SEPA organized a joint effort of 14 provinces, autonomous regions and municipalities in the “Three Rivers and Three Lakes” areas to formulate the plan based upon comments that were extensively collected from the State Development and Planning Commission, State Economic and Trade Commission, Ministry of Finance and Ministry of Water Resources. The plan was submitted to and got approved by the State Council.



The Huai River flows south of the Yellow River through Henan, Anhui and Jiangsu Provinces, helping drain the North China Plain between the Huang Ho (Yellow River) and the Yangtze. It is 660 miles (1,100 km) long and drains an area of 67,000 square miles (174,000 square km). The Huai Re flows eastward through a very flat plain into Hongze Hu (lake) in Jiangsu province, and from there it drains through many small channels into the Yangtze River.


It comes from industrial sources. The major pollution indicators were ammonia nitrogen, BOD and permanganate index.




The Hai River proper is very short – only about 43 miles (70 km) long – running from the city of Tianjin to the Bohai Sea.  It is formed from the confluence of a number of rivers that run from the mountains to the north and west.  The surrounding area is quite flat and flood-prone, and the region does not have enough water year round to meet local needs for industry and agriculture. Industry is being encouraged to recycle water to help relieve the problem, but this will probably not be enough to reduce the serious pollution in this river. Major projects to bring water from southern rivers are under consideration.


The pollution in Hai River Basin was serious. The major pollution indicators were mercury, petroleum and ammonia nitrogen.


The Liao River system drains the southern part of the Liao and Sungari plains of central Northeast China, in Liaoning Province and Inner Mongolia. The river is about 836 miles (1,345 km) long. The region is very flat, and the Liao frequently floods in the summer. As well as being very heavily polluted from industrial sources, the Liao carries a heavy load of silt.


The pollution in Liao River Basin was severe. The major pollution indicators were BOD, ammonia nitrogen and volatile phenols. Efforts to control pollution include the closure of many factories with obsolete technology and the construction of wastewater treatment plants.

CHANG JIANG (Yangtze River)

The Yangtze is the longest river in Asia (6,300 km or 3,900 miles). Its source is in the Kunlun Mountains in Qinghai Province. From there it flows south through Sichuan and Yunnan provinces, and then east across central China through Hubei, Anhui and Jiangsu provinces. It flows into the South China Sea just north of Shanghai. The Yangtze runs through the famous Three Gorges area between the cities of Chongqing and Yichang. After that point, the river has descended to a lower elevation and is navigable for shipping.

The Three Gorges Dam, which is scheduled for completion in 2009, is just above the city of Yichang. This dam will generate much-needed electricity and help control flooding, but changes to the river will have significant environmental impacts.

While the Yangtze is not nearly as polluted as some other Chinese rivers, changing the speed of the flow will cause pollutants to remain in the river longer, especially above the dam. Efforts to control pollution include industrial and municipal wastewater treatment, and reforestation of the riverbanks.

The Chinese Communist Party has approved a dollars 25 billion project to channel the water of the Yangtze River along a 1,200-kilometer route to drought-stricken northern China


The Yangtze, together with its tributaries and the Grand Canal (which links it to Yellow River) is an essential part of the transportation system of south China.

HUANG HE (Yellow River) 

The Huang He is the second largest river in China, at 3,390 miles (5,460 km.) It begins in the Kunlun Mountains in Qinghai Province and flows east, then northeast, through Gansu Province. It flows between the Ordos and Gobi Deserts, and then south through steep valleys of yellow loamy soil (loess) between Shanxi and Shaanxi provinces. Silt picked up here gives the river its distinctive color. It is estimated that the Yellow picks up a billion tones of silt.

The river then runs east through Henan and Shandong provinces, through a flat, heavily populated region. The Chinese have tried to control the Yellow’s flooding for millennia with the use of dikes.

This, combined with the settling out of the loess sediment, has raised the level of the river above the surrounding land – in some places as much as 20 meters (70 ft.)  Disastrous floods still occur. The Yellow River eventually reaches the Bohai Sea, creating a massive delta of its sediment.

Efforts to improve the quality of the Yellow River focus on reducing erosion in loess area by increasing forestation. In recent years, the flow of the Yellow has been low, aggravating the problem of municipal and industrial pollution.


The water quality in Yellow River Basin was, in general, relatively poor. The major pollution indicators were petroleum, permanganate index and BOD



A benzene slick moving down the Songhua River and forcing the suspension of drinking water to 3.8 million people in the Chinese city of Harbin has highlighted the plight of an estimated 190 million people in the country who regularly drink polluted water.


Ecological Water Diversion Project

In the in-land river basins of Talimu River and Hei River, the ecological water diversion projects were kept being implemented, which revitalized a large area of diversiform-leaved Poplar forest in the downstream areas of Talimu River and Hei River. The environment was obviously improved.
Water Pollution Prevention and Control in the Three-Gorges Reservoir Area and the South-to-North Water Diversion Project

In order to implement the “Program of Water Pollution Prevention and Ecological Conservation in the Three-Gorges Area and Its Upper Streams” and the “Program of Water Pollution Prevention and Control along the Central Route of South-to-North Water Diversion”, SEPA conducted a special inspection on the clean-up of the watershed and the prevention and control of pollution caused by vessels in the Three-Gorges Reservoir area, and the water pollution prevention along the central route of the South-to-North Water Diversion.

Charging for the Use of Urban Infrastructure Policy and Polluter-pays Policy

In 2002, the Ministry of Construction, State Development and Planning Commission and SEPA jointly promulgated the Notice on Strengthening the Collection of Wastewater Treatment Charges and Setting up of A Sound Operating Scheme of Urban Wastewater Discharge and Its Centralized Treatment. The Notice on the Collection of Municipal Sewage Treatment Charges and the Promotion of the Industrialization of Garbage Treatment was also promulgated and implemented.



Tai Hu is the third largest freshwater lake of China. It is located in the southern part of Jiangsu Province, just west of Shanghai and the coast. The crescent-shaped lake has a surface area of around 2400 square km.

The surrounding area is a densely populated fertile delta plain with many small lakes, ponds, streams and man-made canals, including the Grand Canal. The inflowing water comes mainly from mountains to the west and southwest, and the outflowing channels exit from the east coast of the lake. Several channels connect the lake with the Yangtze, all of which are controlled by dams to maintain the lake water level.

Tai Hu is famous for its abundant production of fish and crabs as well as for its beauty.


Because the Tai Hu is a major source of water for this rather industrialized region, and pollution from industrial waste, sewage, and agricultural runoff is serious. There is contamination from heavy metals, and the lake water is also highly eutrophic (rich in mineral and organic nutrients that promote a proliferation of plant life) with frequent blooms of blue-green algae, which reduces the dissolved oxygen content. Efforts to control pollution at Tai Hu include the closure of some of the worst polluting factories, a reduction in the use of detergents with phosphorous, and the improvement of municipal sewage treatment.


Chao Lake is near the center of Anhui Province, 15 km east of the capital, Hefei City. Chao Hu is the fifth largest freshwater lake in China, with a surface area of about 750 square km, and it is famous for its beautiful landscape and historic sites. The area around Chao Hu is an agricultural region, with about 5 million people living in surrounding cities and towns. The lake is the major source of water for drinking and irrigation. Fishery is also an important industry.


The most pressing problem in the Chao Lake basin is eutrophication. Chao Lake has high nutrient concentrations from chemical fertilizer runoff, and therefore frequent algae blooms, which reduce the available oxygen, killing fish and other organisms.

Also, the nearby cities have grown greatly in recent years, and their industrial wastewater and household sewage go into the lake. Efforts to clean up Chao Hu include the closure of some of the worst polluting factories, the improvement of municipal sewage treatment, a reduction in the use of phosphorous-containing detergents, some changes to farming practices, and adding fish which eat the algae.


Dian Chi, China’s sixth largest freshwater lake, lies just south of Kunming, the capital of Yunnan province. The lake is about 340 square km. The area is a highland plateau, and very beautiful, but Dian Chi has become highly polluted and eutrophic, with serious algae problems.


Dian Chi is polluted by industrial wastes, domestic sewage and agricultural runoff. In recent years, sewage treatment plants for Kunming have been constructed, and now almost 60 percent of the city’s sewage is treated (three times the national average.) Also, industrial pollution has been reduced. However, clean-up measures to date have failed to stem the pollution because they have focused almost exclusively on point sources around the lake. They have not addressed agricultural runoff nor pollution of the lake’s tributaries.
