Introduction
Rising urbanization, booming industrialization, and associated anthropogenic activities are the prime reasons that lead to air pollutant emissions and poor air quality. It is expected that by 2030, around 50% of the global population will be residing in urban areas (Gurjar, Butler, Lawrence, et al. 2008). More than 80% of population in urban areas is exposed to emissions that exceed the standards set by World Health Organization (WHO 2016). Air pollution is one of the key global health and environmental concerns (Nagpure, Gurjar, Kumar, et al. 2016) and has been ranked among the top five global risk factors of mortality by the Health Effects Institute (HEI 2019). According to HEI’s report, particulate matter (PM) pollution was considered the third important cause of death in 2017 and this rate was found to be highest in India. Air pollution was considered to cause over 1.1 million premature deaths in 2017 in India (HEI 2019), of which 56% was due to exposure to outdoor PM2.5 concentration and 44% was attributed to household air pollution. As per WHO (2016), one death out of nine in 2012 was attributed to air pollution, of which around three million deaths were solely due to outdoor air pollution.

Inpex Corp, Japan’s biggest oil and gas producer, said it is targeting net-zero carbon emissions by 2050 through the expansion of renewable and hydrogen energy as well as the use of carbon capture technology.
INDIA TO WITNESS FASTEST RISE IN ENERGY DEMAND BY 2040: IEA
In a report titled, ‘The India Energy Outlook 2021’, the International Energy Agency (IEA) said, the rapid expansion of solar power combined with favourable policies is transforming India’s electricity sector, allowing the country to offer clean, affordable, and reliable power to a growing number of households and businesses.
EMISSIONS CONTROL IN THERMAL POWER STATIONS: A Long Road to Cross
In this article, Raghav Pachouri brings out the current situation and the challenges confronting us regarding emissions control in thermal power stations (TPSs) in India. While analysing the impact of the power sector on air pollution levels, he highlights the current status of compliance in India (especially Delhi-NCR and critically polluted areas) till June 2020 after revised emission norms for TPSs came into effect on December 7, 2015. He also dwells on the major roadblocks in the timely compliance of emission norms and also offers a few solutions.
Managing Air pollution From Crop Burning
The perils of crop-residue burning contribute to major environmental degradation. In this article, TCA Avni and Sunil Dhingra discuss how the practice of stubble burning is responsible for poor air quality and loss of agricultural biodiversity. They highlight the importance of managing paddy residue and offer sustainable solutions, incentives, and alternatives to crop burning.
