New data published by the Centre for Research on Energy and Clean Air (CREA) reveals that the overall 2023 air pollution levels in Jakarta were arguably the worst since 2019. Despite improvements between 2020 and 2022, the rise of pollution in 2023 is a notable setback. Over 29 million people …
The objective of this study is to conduct a comparative analysis of winter pollution PM2.5 levels in major cities in India, Including Mumbai, Varanasi, Patna, Delhi, Chandigarh, Lucknow, and Kolkata, for the years 2022-2023 and 2023-2024. By analysing temporal trends in PM2.5 levels and comparing pollution levels across cities, this …
Bihar's Begusarai emerged as the world's most polluted metropolitan area while Delhi was identified as the capital city with the poorest air quality, according to this report by the Swiss organisation IQAir. The 2023 World Air Quality Report provides a global review of air quality data for the year 2023. …
India’s air quality deteriorated in January 2024, as the winter season and low wind speed trapped pollutants near the surface, according to this report by the Centre for Research on Energy and Clean Air (CREA). The report, titled “India Monthly Ambient Air Quality Snapshot: January 2024”, analysed the data from …
Under Section 12 (l) of the Commission for Air Quality Management in NCR and Adjoining Areas Act,2021, the Commission is vested with powers to take all such measures, issue directions, etc., as it deems necessary or expedient for the purpose of protecting and improving the quality of the air in …
Air pollution is a major threat to health, and the dangers are particularly acute in low- and middle-income countries. However, little is known about how the burden of pollution is spread across the wealth distribution in these countries. This paper uses new data providing high-resolution wealth estimates for more than …
The National Clean Air Programme (NCAP) was launched in India in 2019 and aimed to significantly enhance the air quality in India by 2024 by reducing PM concentration by 20-30 per cent, which in 2022 has been extended to 2026, aiming to have a 40% reduction in pollution levels compared …
An analysis by the Delhi Pollution Control Committee (DPCC) has revealed a substantial rise in fine particulate matter on Diwali, with a 45 per cent increase in PM2.5 and a 33 per cent increase in PM10, compared to the previous year. The DPCC’s report emphasised that nearly all air quality …
Based on the need to establish scientifically robust health-based standards, this working paper evaluates the global best practices for setting or revising air quality standards. Through this, suggest a structured approach to revising the current and future NAAQS – through an inclusive, expert-driven institutional process, with appropriate timelines, evidence integration, …
This document summarizes several air quality measurement and modelling methods that can be used to estimate ground-level air pollutant concentrations and presents multiple approaches to monitoring ambient air pollution at different spatial and temporal scales. These methods are crucial for estimating population exposures, which can be defined as the product …
Rising air pollution can cut life expectancy by more than five years per person in South Asia, one of the world’s most polluted regions, according to a report which flagged the growing burden of hazardous air on health. The region, which includes the world’s most polluted countries of Bangladesh, India, …
The Air Quality Management (AQM) system in Tajikistan needs strengthening in its key policy and institutional as well as technical aspects to reduce health impacts of air pollution in the most polluted airsheds (Dushanbe and other urban centers). The World Bank's first engagement to strengthen Tajikistan's AQM aims to develop …
Exposure to fine particulate pollution (PM2.5) increases mortality and morbidity and reduces human capital formation and worker productivity. As a consequence, high levels of particulate pollution may adversely affect economic activity. Using a novel dataset of changes in the annual gross domestic product of Indian districts, this paper investigates the …
As air pollution mitigation strengthens in the cities under the National Clean Air Programme, a recent analysis by Climate Trends brought attention to the rural regions in the country. The analysis used the SAANS satellite data and found that dangerous levels of particulate matter affect the rural regions too. Data …
South Asia is home to 9 of the world's 10 cities with the worst air pollution. Concentrations of fine particulate matter (PM2.5) in some of the region's most densely populated and poor areas are up to 20 times higher than what the World Health Organization considers healthy (5 micrograms per …
Air pollution in recent years has become one of the most critical environmental issues. According to the 2021 World Air Quality Report, almost every Indian city exceeded the recommended WHO air quality levels. In India, the national ambient air quality standards (NAAQS) for some pollutants are already higher than the …
Since 2011, WHO has been compiling and publishing ground measurements of air quality and, specifically, the annual mean concentrations of particulate matter with a diameter ≤ 2.5 μm (PM2.5) and ≤ 10 μm (PM10). The objective – beyond summarizing the current state of air quality – is to collect data …
Much of what is currently known about the adverse effects of ambient air pollution comes from studies conducted in high-income regions, especially North America and Europe, with relatively low air pollution levels. More recently, studies of long-term ambient air pollution exposure and its effect on morbidity and mortality in low- …
Jharkhand is a mineral-rich state in India. Its cities have access to various solid fuels and proximity to several heavy industries. These factors, along with the movement of traffic (public and goods), contribute to air pollution in the state. The Ministry of Environment, Forest and Climate Change (MoEFCC), under the …
Rapid population growth, industrialization, and urbanization combined with delayed enactment of environmental policies have led to serious air quality problems across Asia. In particular, the increase in fossil fuel consumption, as well as industrial production, vehicle use, and fertiliser application has driven an increase in air pollutant emissions over recent …
