Land use and buildings: Mumbai ranks average in land use and buildings. While Mumbai scores well for having the highest population density in the Index, it scores poorly for green spaces per person. The city only has 7 square metres of green space per person versus the Index average of 39 square metres, and the Indian city average of 17 square metres. It is also marked down for only having partial policies to contain sprawl and to protect its green spaces and other environmentally sensitive areas. Mumbai is also among the weakest in the Index at providing incentives and regulations to motivate business and households to lower their energy use. However, it does have eco-building standards in place for both private and public buildings, and receives full marks for publicly promoting ways to save energy in buildings.
