India's situation vis-a-vis Co2 emissions..

This amazing graphic shows that as of early april 2017, just 10 countries were emitting 75 % of the current CO2 emissions, India at no. 4 ! The graphic treats the EU as one country and in many respects it behaves like one.


In 2015, just 13 % of the energy used by the world was not sourced from fossil fuels.

Fossil fuels are dominant in the global energy mix, supported by $523 billion subsidies in 2011, up almost 30% on 2010 and six times more than subsidies to renewables.
In India in 2016, just 7 % of the total energy use was drawn from non-fossil fuel sources. Over 60 % of the Indian population used solid fuels (wood, charcoal, coal, etc.) for their energy needs in 2016. A 2016 paper says that traditional energy sources such as biomass account for over 26% of India’s total primary energy consumption. That is more than India’s consumption of oil, which stands at 24%.

A sizeable quantum of energy requirements (40% of total energy requirement), especially in the rural household sector, is met by non-commercial and traditional energy sources, which include fuelwood, crop residue, biomass and animal waste, including human and draught animal power. 


Biomass is a renewable energy source and its use for energy generation is carbon-neutral fuel. It is carbon neutral because it would also release global warming green house gasses like methane and carbon dioxide when it is left to degenerate without using as energy source. In 2009-'10, over 80 % of Indian rural households and nearly 20 % of urban households, used biomass for cooking. Nearly a third or more of urban households in four states used biomass for cooking : Orissa, Kerala, Bihar and MAdhya Pradesh. 


Over half the world's energy use was consumed by industry in 2012. Half that by transport and 20 % by residential and commercial applications. 


68 percent of India’s emissions between 2005-2013 came in from the energy sector. Within the energy-sector, about 77 percent emissions come from electricity generation.

Air pollution in India is a serious issue with the major sources being fuelwood and biomass burning, fuel adulteration, vehicle emission and traffic congestion.[1] In autumn and winter months, large scale crop residue burning in agriculture fields – a low cost alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution. A 2013 study on non-smokers has found that Indians have 30% lower lung function compared to Europeans.
