Chinese cities are 'worst' in terms of CO2 emission
Feb 27, 2011 - McClatchy-Tribune Regional News - energycentral.com
Chinese cities have the highest carbon emissions per capita and energy
consumption per unit of GDP in Asia, while Singapore is the region's
greenest metropolis, a study released by the German engineering company
Siemens and the Economist Intelligence Unit has showed.
Shanghai, Guangzhou and Beijing have the highest levels of CO2 emissions
per capita among the 22 cities measured by the Asian Green City Index, which
evaluates the environmental performance of major Asian cities in eight categories
-- CO2 emissions, energy, buildings, transport, water, waste and land use,
air quality and environmental governance.
Shanghai emitted CO2 of 9.7 tons for each person annually, well above the
average of 4.6 tons. The city also has the highest energy consumption per unit
of GDP at 14.8 megajoules (MJ) for each dollar, whereas the average is 6.0
MJ a dollar.
Singapore came out on top of the index as the only city that was ranked "well
above average" across all eight categories. Meanwhile, Karachi in Pakistan
was ranked the worst in overall environmental performance among the 22 Asian
The study also showed that Chinese cities are strong on government policies
that focus on massive investments to improve air quality, landscaping and public
transportation, indicating that environmental awareness and climate protection
guidelines are playing an increasingly important role.
According to the index, Nanjing, the capital of Jiangsu province, generates
the third-lowest amount of waste for each person while Guangzhou, Beijing and
Wuhan, the capital of Hubei province, are in the top five for green spaces.
Barbara Kux, chief sustainability officer at Siemens, said that the rapid
pace of urbanization has posed unprecedented environmental challenges for Asian
cities, and that these areas are key in achieving sustainable development globally.
Kux said that Asia is currently the fastest-growing market for Siemens' green-
technology products and the company plans to further grow its environmental
business in the region to tap the rising demand for green products and services.
The company aims to increase its sales of energy-saving environmental products
to 40 billion euros (US$55 billion) by 2014, according to Kux.
Siemens' revenue from green-technology products and services totaled about
28 billion euros in the 2010 fiscal year, accounting for more than a third
of its total revenues.
The company has supplied the high-voltage direct-current (HVDC) transmission
system, which transmits 6,400 megawatts of hydropower from southwestern China
to Shanghai over a distance of about 2,100 kilometers.
It is by far the longest low-loss electricity transmission system of its
type and is scheduled to start commercial operations in 2012.
