Asian Green City Index

A study commissioned by Siemens and conducted by the Economist Intelligence Unit has analysed the aims and achievements of 22 Asian cities with respect to environmental and climate protection. The Asian Green City Index has some key interesting insights:

• Singapore is Asia's greenest city by far. The city state stands out for its ambitious environmental targets and its efficiency in achieving them. 
• It is heartening to note that other cities are increasingly becoming aware about the importance of environmental protection and climate change issues.
• Bangalore has the lowest levels of CO2 emissions per capita- 30% of Bangalore's energy needs are met by renewable sources and 61% of the electricity generated is through hydropower. The city's low energy lifestyle (due to relatively low income) plays a big part in CO2 reductions. The impact is further reduced due to the city's economy being dominated by IT- related businesses rather than heavy industry. 
• Delhi with a population of 17.4 million, surprisingly has one of the lowest levels of CO2 emissions and generates the least amount of waste per capita of all the 22 cities surveyed. Delhi's average per capita income of $2000 is more than twice the national average but it is among the poorest in the Index. Perhaps that explains the low emissions and waste levels.  
• Bombay with a population of 12.7 million is the most densely populated city in the Index with a GDP per capita of about $2200. It is one of the least prosperous cities in the Index. No prizes for guessing that it performs well in energy and CO2. Given its size and population density, it fares well in terms of land use, buildings and water. The city benefits from a relatively high share of renewable energy at 21% for its electricity needs.
