Mumbai is one of the densest cities in Asia with 27,000 people per square kilometre, the Asian Green City Index reveals in its latest report.
The Asian Green City Index, commissioned by Siemens and Economist Intelligence Unit (EIU), analysed the environmental sustainability of 22 major cities in Asia with respect to environmental and climate protection and announced the report in Singapore on Monday.
The Asian Green City Index was conducted in 22 Asian cities including Singapore, Tokyo, Seoul, Bangkok, Beijing, Delhi, Shanghai, Bengaluru, Kolkata and Karachi.
Of these, Mumbai has the highest density of population with 27,000 people crammed into one square kilometre — 27 times more tightly packed than Wuhan in China that has less than 1,000 people per square kilometre.
Mumbai is marked below average on the Green City Index along with Kolkata, Bengaluru, Hanoi and Manila.
The report also says that Mumbai has a fragmented energy delivery market, which makes overarching conservation projects difficult.
Kolkata recorded low levels of water consumption at 138 litres per person per day.
This is one of the best rates among the 22 cities, but could also be due to the lack of water supply as mentioned in the report.
Delhi has an extraordinarily low per capita waste generation figure of 147 kg per year.
The city’s advanced policies, strategies to reduce, reuse and recycle waste have benefited it. Bengaluru has some of the lowest levels of CO 2 emissions per capita.
The Asian Green City Index examined the environmental performance of 22 cities in eight categories — energy and CO2, land use and buildings, transport, waste, water, sanitation, air quality and environmental governance.
And overview of the overall Asian Green City Index study put Mumbai, Bengaluru and Kolkata in the below-average category, while Delhi was in the average category.
When asked about the Indian cities featured in the report, Dr Armin Bruck, MD, Siemens Ltd, said, “India has witnessed a tremendous economic boom in the last decade, so much so that infrastructure development in terms of roads, water management, etc, is yet to keep pace with the needs of the cities – thus affecting the ‘environment friendliness’ or ‘green levels’ within cities.”
