An increase in greenhouse gases leads to global heating. The World Bank notes that carbon
dioxide accounts for 58.8% of these gases . Soytas and Sari  recognize that human
activities have greatly contributed. More than 80% of the existing world energy demand
derives from fossil fuels . World action is necessary to achieve zero or low-carbon
growth. India is the fourth largest contributor to GHG (approximately 5% of overall
GHG emissions) and its CO2 emissions rose by 5.2% between 1990 and 2009 (based on
the compound annual growth rate) . In India, more than 68% of electricity is produced
by coal, which is a major source of CO2 emissions (58% of GHG emissions come from the
energy industry and more than 65% of which is generated by electricity) .
India’s energy output in 2013–2014 was dominated by coal and lignite with a share of 73.48% of overall
production, followed by 11.81% of crude oil and 10.18% of natural gas. India is one of the
world’s fastest growing emerging economies and the world’s second most populated
country with over one billion inhabitants, suggesting that in the coming decades, its energy
demand and CO2 emissions will continue to increase in the age of globalization .
