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 …
The most commonly-known f-gases are the early, so-called first generation F-gases: the CFCs that destroyed the ozone layer and were banned by the Montreal Protocol. However, in the race to save the ozone layer, the use of their second generation cousins was accelerated: HCFCs, now also banned under the Montreal …
Breathing polluted air for even two hours can boost blood pressure, potentially raising the risk of cardiovascular disease in those exposed to smog, a new study suggests. Although the increase may not mean much for healthy people, "this small increase may actually be able to a trigger a heart attack …
The United Nations Secretary General (UNSG) in his message to commemorate the International Day for the Preservation of the Ozone Layer, on Wednesday, has urged for implementation of agreed environmental goals, targets and objectives for protection of the "Earth's Protective Shield." "Without action on climate change, the world faces profound …
Pune In a bid to bring down the emission levels of Hydrochloroflurocatrbons (HCFC) in the city, the United Nations Environment Programme (UNEP) has shown its intent to initiate a meeting with the CEOs of the industries in Pune in March 2010. It will probably be the first time that an …
The Montreal Protocol on Substances that Deplete the Ozone Layer has since been recognized as an extraordinary environmental success in global cooperation to protect the ozone layer. The Montreal Protocol has completed more than 20 years of its progress. India being a Party to the Montreal Protocol and all its …
Most initiatives to slow global warming involve reducing carbon dioxide emissions. Little attention has been given to reducing emissions of the light-absorbing particles known as "black carbon" or the gases that form ozone--even though doing so would be easier and cheaper and have a more immediate effect. At last, world …
A solution that detects minute presence of ozone, even in cells ozone in the stratosphere protects the earth from harmful ultraviolet rays. But when in the troposphere, near the ground level, it acts as a pollutant. Though it is not emitted directly, emissions from car engines or industrial operations react …
Results of ambient air quality monitoring carried out during 2008 at various monitoring stations under National Air Quality Monitoring Programme by the CPCB. Pollutants found to exceed the standards in many cities are suspended particulate matter and respirable suspended particulate matter. Results of additional pollutants such as benzene and carbon …
Federal Government is preparing a plan to minimise the adverse impact of climate change on livestock. The plan will focus on provision of shading, improved airflow, reduced crowding, alerted diets and provision for ensuring animal health. According to official sources of Planning Commission, a new national forestry policy with institutional …
In your Special Report 'Cutting out the chemicals', you discuss the possible shift of regulatory control of hydrofluorocarbons (HFCs) from the UN Framework Convention on Climate Change to the Montreal Protocol (Nature 457, 518
Atmospheric aerosols (a mixture of solid or liquid particles suspended in the air medium) are short-lived, with a residence time of about a week in the lower troposphere. Unlike the principal greenhouse gases, aerosols are more concentrated in the source regions and exhibit strong spatial and temporal variations.
A new scientific study has warned that if use of 'super greenhouse gases', known as hydrofluorocarbons or HFCs, is not controlled it could contribute to global warming. According sources here on Wednesday, these findings were made by an international team of researchers. Hydrofluorocarbons (HFCs) were originally developed to replace the …
Hydrocarbon (HC) refrigerants are a "natural" cooler widely used in domestic and commercial refrigerators all over the world, except in the U.S. and Canada. HC refrigerants produce less greenhouse gasses than hydrofluorocarbon (HFC) technology, but they aren't approved for the U.S. market - yet. Now Greenfreeze, the Greenpeace-developed HC refrigerant, …
In National Capital Region (NCR) of Delhi, spreading ~900 Sq. km, the increasing air pollution poses a serious problem due to its direct impact on human health, such as increased incidences of chronic bronchitis, cancer of the respiratory tract, asthma, and induced premature mortality. Increase in motorization (with ~600 vehicles …
Plea to phase down a potent greenhouse gas TWO island nations vulnerable to climate change impacts, Micronesia and Mauritius, have sought curbs on a chemical that could represent a third of the total greenhouse gas (ghg) emissions by 2040. In a joint representation, the two countries sought US support to …
New Delhi: If you feel dizzier in summer, there is a good reason for it. As the mercury mounts, a little-known summer pollutant comes to play, jeopardising public health. Ozone
