Carbon Emission Current Affairs - 2020

CO2 Emissions of India falls in 4 decades

According to the study conducted by Centre for Research on Energy and Clean Air (CREA), the Carbon dioxide Emissions in India has declined the least in four decades.

Highlights

The study says that the carbon dioxide emissions in India has reduced by 15% in March and by 30% in April. The study also says that the latest consumption of oil and gas, coal has declined. It has fell by 30 million tonnes in 2019-20 in the country as compared to that of the previous year.

Fossil Fuel uses

The carbon dioxide pollution in the country is mainly caused due to power and transportation sector. The decline in consumption of fossil fuels is also the main reason for the reduction in pollution. The power generated by coal-fired power plants reduced by 15% in March for the first time. Also, the renewable energy generation has increased by 6.4% in March.

The carbon dioxide emission also slowed down due to slowdown in coal-fired electricity generation.

Black Carbon Levels in Himalayan Glaciers and Biomethanation

The Wadia Institute of Himalayan Geology (WIHG) conducted study near Gangotri Glacier in 2016. According to the study, the black carbon concentration in the region has increased by 400 times.

Highlights

The increase in carbon concentration in the region is mainly because of agricultural burning and forest fire. The concentration of black carbon was found to be minimum in August and maximum in May.

What is Black Carbon?

Black Carbon are fine particles of carbon that are formed due to incomplete combustion of fossil fuels and biomass. These particles are capable of absorbing energy from the sun (light) a million times more than that of carbon dioxide. However, black carbon are short lived unlike carbon dioxide.

They increase current level of global warming mainly due to their light absorbing characteristics.

Biomethanation

The Government of India has taken the technology of Biomethanation as a solution for stubble burning. Quality manure and biogas are obtained from bio-methanation process. Six biomethanation plants are to be constructed in Punjab that will convert paddy straw into bio-gas.

Biomethanation is a process by which organic materials are microbiologically converted into biogas in anaerobic conditions. Anaerobic condition is an environment without oxygen.
