Order of the National Green Tribunal in the matter of News Item titled “CSE report finds dangerous increase in ozone pollution across urban India” appearing in Down to Earth dated 06.08.2024. The Principal Bench of the NGT heard the matter on March 21, 2025. In the original application, registered suo …
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 …
The stratosphere ozone layer is slowly recovering and the recovery will be complete in most parts of the atmosphere in the coming decades, according to the latest bulletin by the World Meteorological Organization (WMO). The bulletin with the updated status of the ozone layer by WMO-Global Atmosphere Watch bulletin returned …
The deteriorating quality of air, transboundary haze pollution and global climate change are the major problems affecting the atmospheric ecosystem. Air quality has deteriorated as a result of increasing traffic congestion, rapid industrialisation and increased energy consumption. Tackling air pollution in the Asia and Pacific region is of utmost urgency, …
Science has been one of the foundations of the success of the Montreal Protocol. This assessment highlights advances and updates in the scientific understanding of ozone depletion since the 2018 Scientific Assessment of Ozone Depletion and provides policy-relevant scientific information on current challenges and future policy choices. The latest edition …
This full version of the IPCC Fifth Assessment Report Climate Change 2014: Impacts, Adaptation, and Vulnerability released on 16 October 2014 provides the most comprehensive look to date at the widespread impacts and risks of climate change and the opportunities for response. There has been an evolution in the treatment …
Air pollution is increasingly understood as a global issue, requiring an understanding of pollution sources, transport, and transformation from local to regional to global scales (IPCC, 2013). Polluting gases, such as ozone (O3) and aerosols, particularly PM 2.5, are known to be major risk factors for public health (Cohen and …
New WHO Global Air Quality Guidelines (AQGs) provide clear evidence of the damage air pollution inflicts on human health, at even lower concentrations than previously understood. The guidelines recommend new air quality levels to protect the health of populations, by reducing levels of key air pollutants, some of which also …
The assessment highlights the critical role that cutting methane emissions, including from the fossil fuel industry, plays in slowing the rate of global warming. Cutting human-caused methane by 45% this decade would keep warming beneath a threshold agreed by world leaders. There are multiple benefits to acting including: the rapid …
Better air quality has led to a significant reduction of premature deaths over the past decade in Europe. However, the European Environment Agency’s (EEA) latest official data show that almost all Europeans still suffer from air pollution, leading to about 400,000 premature deaths across the continent. The Air quality in …
Aviation emissions have been found to cause 5% of global anthropogenic radiative forcing and ~16 000 premature deaths annually due to impaired air quality. When aiming to reduce these impacts, decision makers often face trade-offs between different emission species or impacts in different times and locations. To inform rational decision-making, …
This report presents an updated overview and analysis of air quality in Europe from 2000 to 2017. It reviews the progress made towards meeting the air quality standards established in the two EU Ambient Air Quality Directives and towards the World Health Organization (WHO) air quality guidelines (AQGs). It also …
This guidance document provides a practical framework that can be used to identify, prioritise and include mitigation measures that can increase a country’s climate change mitigation ambition through actions that improve local air quality. It also outlines how this can be reflected in the updated Nationally Determined Contribution and accompanying …
Question raised in Lok Sabha on Rise in Ozone Levels, 28/06/2019. The monitoring data of ozone in Delhi-NCR is regularly displayed on Central Pollution Control Board (CPCB) website on real time basis. The analysis of AQI for Delhi reveals that during last three years (2016-2018), ozone was reported as prominent …
Air Quality Index also expected to slowly deteriorate in the next two days With rising temperatures, surface ozone pollution is expected to increase in Delhi in the next three days, according to a forecast by the System of Air Quality and Weather Forecasting and Research (SAFAR). “Surface ozone can lead …
The Assessment documents the advances in scientific understanding of ozone depletion reflecting the thinking of the many international scientific experts who have contributed to its preparation and review. These advances add to the scientific basis for decisions made by the Parties to the Montreal Protocol. It is based on longer …
Majority of Australians rate climate change as a bigger threat to the country's interest compared to global terrorism, a study has found. Almost 64 per cent of Australians have called climate change as 'a critical threat' —an increase of six points from 2018 and 18 points since 2014, according to …
Genetics may partially explain observed heterogeneity in associations between traffic-related air pollution and incident asthma. The aim of the study was to investigate the impact of gene variants associated with oxidative stress and inflammation on associations between air pollution and incident childhood asthma.

Green roofs -- roofs that are planted with vegetation -- may improve the indoor air quality of commercial buildings by cutting the amount of ozone coming into the buildings from the outside, according to new research from Portland State University. The findings add to the already known environmental benefits of …
This publication marks the twenty-fifth anniversary of the WMO Statement on the State of the Global Climate, which was first issued in 1994. The 2019 edition treating data for 2018 marks sustained international efforts dedicated to reporting on, analysing and understanding the year-to-year variations and long-term trends of a changing …
