Issues like energy conservation and emissions reduction, seawater desalination, alternative energy and circulative economy are becoming the most popular topics of Tianjin. During recent years, through transforming the economic growth pattern, the local government has been giving top priority to energy conservation, pollution reduction, eliminating backward production capacity. Tianjin has squeezed into the top tier of energy efficient and environmental friendly cities.

According to Tianjin Development and Reform Commission, Tianjin has been actively pushing forward structural reform. On one hand, the Municipal Government has been encouraging the development of a bunch of high-tech industries with high added value, low energy consumption and light pollution, including aerospace and aviation, information technology, equipment manufacturing, wind power, alternative energy and materials, light and textile industry. On the other hand, small-scale enterprises with backward technique and heavy pollution, such as small steelworks, cement plants, glassworks, paper mills, have been shut down, and small thermal power generator units have been closed. Tianjin encourages large enterprises to implement technical innovations that promote energy conservation and emission reduction, and promotes the development of modern service industry.

Starting from establishing and developing the coordinated mechanism of the circulative economy, Tianjin has set up the incentive mechanism, which boosts the circulative economic development. Meanwhile, Tianjin has established a bunch of circulative economic experimental demonstration projects, campuses, enterprises and small towns in the key industrial segments, built certain circulative economic industrial chains, and created the social circulation system, which binds various industries together.

Tianjin’s plan for energy conservation and emission reduction is both aspiring and challenging. According to the blueprint, by the year of 2010, Tianjin’s accumulative total of energy consumption per 10,000-yuan GDP will fall by 20 percent over 2005 to 0.89 ton of standard coal, while the accumulative total of energy consumption per 10,000-yuan industrial-added value for scale industrial segments will fall by above 23 percent to 1.12 tons. The water consumption for every 10,000-yuan industrial added value will decrease by some 20 percent to 19.2 cubic meters, and the re-application ratio of industrial waste water will increase from 90 percent in 2005 to 94 percent. The emission of sulphur dioxide will fall by 9.4 percent to 240,000 tons. Chemical oxygen demand (COD) will fall by 9.6 percent to 132,000 tons. What’s more, the centralized process ratio of urban waste water will reach 85 percent by 2010, usage ratio of reclaimed water 30 percent. Innocuous treatment ratio of urban life waste will exceed 90 percent, and the comprehensive usage ratio of industry solid waste will remain above 98 percent.

In order to meet the above goals of energy conservation and emission reduction, Tianjin has released a series of measures. In industries with high energy consumption such as steel, power generation, petroleum and chemical industry and building material manufacturing, ten energy conservation projects have been launched, including utilization of surplus pressure and heat, engine system energy conservation and optimization of energy system. Efforts were made in building energy conservation. The construction of urban sewage disposal plants and pipelines is also accelerated. A greater emphasis is laid on the desulfurization of thermal power plants and coal boiler emission. Tianjin is actively engaged in the construction of an energy-saving comprehensive transportation system, popularization of high-efficiency light-bulbs, and the development of biochemical energy in rural areas.

These measures worked. The Municipality’s comparable GDP growth rate reached 15.1 percent and 16.5 percent respectively in 2007 and 2008, taking the national leading position. At the same time, consumption of energy and other resources has been on a continuous decreasing tendency, which means Tianjin is developing both rapidly and effectively. From 2006 to 2008, Tianjin’s accumulative total of energy consumption per 10,000-yuan GDP has been dropping for three consecutive years, with an annual decrease rate which ranked top three and an accumulative decrease rate of 14.94 percent, reaching 0.947 ton of standard coal in 2008. Tianjin has accomplished 74.7 percent of the plan, ranking 2nd in the country. The accumulative total of energy consumption per 10,000-yuan industrial-added value for scale industrial segments was 1.053 tons of standard coal in 2008, with an accumulative 3-year decrease rate of 27.3 percent, meeting the plan two years in advance. The total water consumption per 10,000-yuan industrial-added value was 15 cubic meters, reaching planned request three years in advance. Re-use ratio of industrial waste water reached 93.92 percent, nearly accomplishing the plan. The total emission of sulphur dioxide, with a 3-year accumulative decrease rate of 9.41 percent, dropped to 240,100 tons, accomplishing 99.6 percent of the planned goal. Total emission of COD, with a 3-year accumulative decrease rate of 8.81 percent, dropped to 133,100 tons, accomplishing 92.1 percent of the target. Moreover, the centralized disposal ratio of urban life waste water reached 79 percent, innocuous treatment ratio of urban life wastes 88.03 percent, comprehensive usage ratio of industrial solid wastes 98.45 percent, and that for the alkali dregs, the steel slag, and the pulverized coal ash soared to 100 percent, all among the top in the country, as well as seawater desalination and reclaimed water usage.
