What’s the per capita usage of water in India?
The per capita availability of water now stands at 1,250 cubic metres. India is in a precarious situation as water availability is concerned, given that the country in which nearly 17 per cent of the world’s population resides has only 4 per cent of the global freshwater resources. [Source]

How much Carbon Dioxide is emitted in a year?
The six billion people on earth emit 400-450 giga tonnes of carbon dioxide a year. That’s around seven tonnes per capita,” says Nicholas Stern, an economist who authored a path-breaking report on the economics of climate change for the British government earlier this year.
The US has per capita carbon dioxide emissions of around 20 tonnes, the European Union has around 10 tonnes, China has 3.5 tonnes and India has per capita emissions of only one tonne. [Source]

So, in a day an Indian uses (read: consumes) 3.4 cubic metres of water and emits 2.7 Kgs of Carbon Dioxide. (pun intended ;p )
