With crop residue burning in northwest India contributing to a quarter of Delhi's air pollution during winter, a professor from Delhi's Jawaharlal Nehru University (JNU) has claimed to have develop

A new study released on Thursday titled "Burden of Disease Attributable to Major Air Pollution Sources in India" has found that residential biomass burning or use of solid fuels inside homes follow

Question raised in Lok Sabha on States Affected by Air Pollution, 15/12/2017. The Government has notified National Ambient Air Quality Standards (NAAQS) which lays the norms for air pollutants in the Country. The NAAQS have been developed taking into account global standards. Central Pollution Control Board (CPCB) monitors the ambient air quality at 691 monitoring stations located in 303 cities/towns covering 29 states

Question raised in Lok Sabha on Air pollution, 15/12/2017. Central Pollution Control Board (CPCB) is monitoring ambient air quality in 691 locations covering 303 cities/towns in 29 States and 6 Union Territories across the country under National Air Quality Monitoring Programme (NAMP). As per the data, the number of cities where monitored values are exceeding National Ambient Air Quality Standards (NAAQS) during 2016 is 21 for NO2, 195 for PM10 and 31 for PM2.5. The ambient air quality data for 2016 is given in Annexure – I.

Residential solid biomass cookstoves are important sources of aerosol emissions in India. Cookstove emissions rates are largely based on laboratory experiments conducted using the standard water-boiling test, but real-world emissions are often higher owing to different stove designs, fuels, and cooking methods. Constraining mass emissions factors (EFs) for prevalent cookstoves is important because they serve as inputs to bottom-up emissions inventories used to evaluate health and climate impacts.

Order of the National Green Tribunal in the matter of Vikrant Kumar Tongad Vs. Environment Pollution (Prevention Control) Authority & Others dated 16/11/2017 regarding air pollution due to burning of agricultural residues. NGT directs NTPC to file complete details of its total demand of coal and how much agricultural residue either in the form of pellet or otherwise it can use, if not purely at least mixed with coal, in all the coal based Thermal Power Houses in the States of Punjab, Haryana, Himachal Pradesh and Uttar Pradesh.

Order of the National Green Tribunal in the matter of Vardhaman Kaushik Vs. Union of India & Others dated 09/11/2017 regarding the deteriorating air quality of Delhi NCR. National Green Tribunal in the Order said that the Judgement of the NGT dated 10th November, 2016 had "clearly postulated the steps that were required to be taken on long term and short term basis keeping in view the precautionary principle to ensure that the ill-effects and adverse impact of polluted ambient air quality in the previous year is not repeated in the year 2017.

The 2015 smoke haze episode was one of the most severe and prolonged transboundary air pollution events ever seen in Southeast Asia (SEA), affecting the air quality of several countries within the region including Indonesia, Malaysia and Singapore. The 24 h mean outdoor PM2.5 (particulate matter (PM) with aerodynamic diameter ≤ 2.5 μm) concentrations ranged from 72–157 μg m−3 in Singapore during this episode, exceeding the WHO 24 h mean PM2.5 guidelines (25 μg m−3) several times over.
