Air Pollution in Delhi Background An AQI between 0-50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor’ and 401-500 ‘severe’. Above 500 falls in the ‘severe-plus emergency’ category. Measures announced under GRAP- Severe+ or Emergency- (PM 2.5 over 300 µg/cubic metre or PM10 over 500 µg/cu. m. for 48+ hours): Stop entry of trucks in
Less pollution, more soil fertility Context: The article discusses the causes of stubble burning in the north Indian states. Stubble burning: Stubble burning refers to the practice of farmers setting fire to plant debris that remains on farms after harvest. The origin of stubble burning can be traced to the advent of the Green Revolution. Mechanised harvesting, a feature of the Green Revolution, utilised the combined harvesting technique which left behind substantial plan
Commission for Air Quality Management (CAQM) Context Air pollution is a serious problem with environmental, public health and economic dimensions. Northern India gets exposed to hazardous levels of air quality almost every year. Acknowledging this public health hazard, the centre government has promulgated an ordinance to set up a Commission for Air Quality Management (CAQM) in National Capital Region (NCR) and Adjoining Areas. Commission for Air Quality Management (CAQM) T
Trends in Air Pollution: CPCB According to a recent study commissioned by the Central Pollution Control Board (CPCB), the rate of increase in pollution levels in southern and eastern India is far greater than in the Indo-Gangetic plain (IGP). It has also been found that air pollution in rural areas has increased at par with urban India. About the Study: It was jointly carried out by IIT-Delhi and CPCB and analysed data from 2000 to 2019. The study, conducted on the basis of sate
UNEP report on CO2 Emissions In its recent report, UNEP highlighted that CO2 emissions from the building sector are highest in 2019. The building sector emitted more than a third of global energy-related carbon dioxide. Of the total global emissions, building operations accounted for 28% & construction-related industries (cement, glass, etc) accounted for 10%. The use of fossil fuels for power generation & carbon-intensive electricity sector contributed to the increased CO2 emi
Vapour Recovery System Context Green concern: Fuel stations are a major source of emission, according to the National Green Tribunal. Committee’s recommendation A joint committee appointed by the National Green Tribunal (NGT) to study air pollution in Kerala has recommended the installation of a vapour recovery system at fuelling stations and retrofitting of diesel vehicles with particulate filters to improve air quality. The report pointed out that petrol refue
World Air Quality Report: Delhi is the most polluted city in the World World Air Quality Report is given by IQAir Visual and Greenpeace. The main objective was to measure the presence of fine PM 2.5. Delhi remained the most polluted capital city in the world but India, on the whole, had improved its average annual PM2.5 (particulate matter) levels in 2020 than in 2019, according to a report from IQ Air, a Swiss air quality technology company specialising in protection against airb

Air Pollution in Delhi UPSC Air Pollution and AQI Context: UPSC GS Paper III – Air Pollution (Prelims – Mains – Interview) What is the National Air Quality Index? Launched in 2014 with outline ‘One Number – One Color -One Description’ for the common man to judge the air quality within his vicinity. The measurement of air quality is based on eight pollutants, namely: Particulate Matter (PM10), Particulate Matter (PM2.5), Nitrogen Dioxide (N
Black Carbon study by World Bank About Black Carbon Black Carbon (BC) =It is a Pollutant as well as a GHG. It is a solid particle or aerosol & a component of Particulate Matter. Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass (like soot & dust), and is emitted in both anthropogenic and naturally occurring soot. It is short-lived. It is the strongest a
Accurate estimation of Black Carbon over Himalaya Accurate estimation of black carbon (BC), the second most important global warming pollutant after CO2, will now be possible using optical instruments in the Himalayan region. Thanks to a parameter called the mass absorption cross-section (MAC) specific to the Himalayan region that scientists have estimated. It will also improve the performance of numerical weather prediction and climate models. Scientists at the Aryabhatta Resear
National Mission on use of Biomass in coal-based thermal power plants Ministry of Power has decided to set up a National Mission on the use of Biomass in coal-based thermal power plants. This would further support the energy transition in the country and our targets to move towards cleaner energy sources. Objectives: To increase the level of co-firing from the present 5% to higher levels to have a larger share of carbon-neutral power generation from the thermal power plants. To tak
Graded Response Action Plan (GRAP) Background An AQI between 0-50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor', and 401-500 ‘severe’. Above 500 falls in the ‘severe-plus emergency’ category. Measures announced under Graded Response Action Plan (GRAP)- Severe+ or Emergency- (PM 2.5 over 300 µg/cubic meter or PM10 over 500 µg/cu. m. fo
Microplastics in Ganga An analysis of the stretches of the river Ganga by a Delhi-based environment NGO, Toxics Link, has revealed pollution by microplastics, defined as synthetic solid particles sized ranging from 1 micrometre to 5 millimetres (mm), which are insoluble in water. The Ganga flows across five States and has been at the centre of a massive multi-crore undertaking by the Union government, in the form of the National Mission for Clean Ganga, to rid it off contamination.
Green Crackers and NGT Green crackers are less harmful and less dangerous than conventional ones. They are the crackers with reduced emission and decibel levels. They are known as 'green' firecrackers because they have a chemical formulation that produces water molecules, which substantially reduce emission levels and absorbs dust. They are cheaper to manufacture and produce 30-35% less SO2 and NO2 emissions. What are the Green Crackers? Traditional firecrac
Aerosol and Climate Change Scientists tracing the concentration, size and evolution of aerosol particles smaller than 3 nanometres at an urban location in India have found the frequent formation of sub-3nm aerosol particles in the atmosphere. This has critical importance as a major fraction of these newly formed particles can reach sizes of cloud condensation nuclei where they have climatic impacts. The formation of small molecular clusters of sub-3nm size is technically called aero

Global Methane Pledge Methane emissions will likely increase by 13 percent by 2030 without the Global Methane Pledge. About Global Methane Pledge: It was launched in 2021, aims to keep alive the 1.5 degrees Celsius goal. Over 100 countries have committed to reducing global methane emissions by at least 30 per cent by 2030 from 2020 levels. This reduction could eliminate over 0.2C warming by 2050 India, which is not a part of the Global Methane Pledge, is among the to
