Green initiatives: An eco-housing program makes it mandatory for construction companies to obtain “Eco-Housing certification” from the city. The programme, launched in partnership between the city government, the United States Agency for International Development, and the International Institute for Energy Conservation, provides incentives to property developers to make their buildings more energy efficient. The incentives include rebates on development charges and some tax allowances. The MEA (Mumbai Energy Alliance) has also successfully piloted an initiative to install new energy-efficient water pumps in buildings around the city. The new pumps have been operational since March 2010 and have resulted in improved efficiency, as well as electricity savings. The pilot initiative is now to be extended and, if implemented in 100,000 buildings, will make annual electricity energy savings of 200 million kilowatthours and reduce CO2 emission by 1.8 million tonnes over a ten-year period.
