Before industrial environmental issue in the world. Slowly the evolution around 1750, amount of CO in the 2 temperature of the Earth is increasing and it has atmosphere was 280 ppm (parts per million). a great deteriorating effect. The World When industries came, more coal was burned Metrological Organisations (WMO) statement emitting more CO to the atmosphere. Earlier 2 on the status of the climate 2015, suggests that whatever CO was produced, it was absorbed 2 average global temperature increased by 0.760 by plants and hence its amount was constant in C as compared to 1961-1990 average. the atmosphere. But it was no longer possible Agricultural scientists have found out that for due to two reasons, one being burning of more each degree of temperature increase, grain coals and the second being reduction of forest yields decline by about 5%. It has been estimated area. As a result, amount of CO in the 2 that maize, wheat and other major crops have atmosphere started increasing year by year experienced significant yield reduction at the and now it has reached to 405 ppm. global level of 40 megatons per year between Thermal power stations and 1981 and 2002 due to warmer climate. Due to transportation system are the major rise of temperature, ice in the poles and high contributors to the emission of CO to the 2 mountains has started melting. Due to this the atmosphere. Burning of coal produces about a mean sea level is gradually rising, which will billion tons of CO each year, about 70% of 2 submerge the small islands and low lying coastal this being from power generation. It is known areas. This may affect thousands of people that CO emission from thermal power stations 2 throughout the world. From 1901 to 2010, the account for 50% of the world total of over 36 global average sea level rose by 19 cm as billion tons of total emissions. oceans expanded due to warming and melting People became aware of the harmful of ice. The Arctics sea ice extent has shrunk in effect of the global warming and climate every successive decade since 1979, with 1.07 change in the 1980s. Then different countries million square kilometre of ice loss every gathered to find a solution for this. Many decade. Another harmful effect of global international conferences were held in different warming is climate change, which may cause parts of the world and discussions were held floods, cyclones, famines etc. to limit the global temperature rise and Some gases, collectively called green formulated some regulations. As CO emission 2 house gases (GHG) cause global warming and is linked to the industrial production and climate change. These are carbon dioxide economy of a country, many countries initially (CO ), methane, nitrous oxide, ozone and water were reluctant to curb the emission of CO . 2 2 vapour. Out of these gases, the impact of CO 2 But environment is more important and so is more as it is emitted to the atmosphere in with much persuasion they agreed for this. large amount and hence control of its emission The International Panel on Climate Change 2 Science Horizon JANUARY, 2019 (IPCC) found that if the global average additional carbon sink of 2.5 billion to 3 billion temperature would not exceed pre-industrial tons of CO equivalent through increasing forest 2 levels by more than 20C, then global CO and tree over by 2030. 2 emission must be reduced between 50-85 % Like most other countries, the main by 2050. source of GHG emission in India is thermal In December 2015, representatives of power plants. Coal is sufficiently available in different countries attended the Paris Climate our country and it is also cheap, so nearly 65% Conference and some concrete proposals have of total electricity generation in India comes been agreed there. The proposal is known as from thermal power. Now as per Indias Paris Agreement. The agreement came into commitment to Paris Agreement, it has to force on 4 November 2016. As of November develop renewable sources of power, which are 2018, 194 countries and the European Union pollution free. India has already taken some have signed the agreement. 183 countries and definite steps in this direction. It has announced the European Union, representing more than clean energy targets of 175 gigawatts (GW) 87% of global GHG emissions, have ratified or which includes 100 GW of solar, 60 GW of accepted the agreement. It was decided to limit wind and 15 GW of other renewables by 2022. the global temperature rise to 20 C above pre- India will now depend mainly on solar energy industrial level and make efforts to limit it to for future electricity. Government is even 1.50 C.

From all sources, the total renewable is known as Intended Nationally Determined power capacity is now 72012.81 MW which is Contribution (INDC). 20.74 percent of the total installed capacity in India has signed the Paris Agreement on the country. India has started Green India October 2, 2016 and has committed to take Mission for restoring forest cover.

However there are also some Source Quantity (Mt/ Year) others, which significantly contribute it and the most important among those is methane.
