An environmental pressure group claimed that Chinese factories are illegally using ozone-depleting CFCs, which have recently seen a spike in emissions that has baffled scientists. The Environmental Investigation Agency (EIA) campaign group said 18 factories in 10 Chinese provinces they looked into admitted to using banned chlorofluorocarbons.

NEW DELHI: Delhi and its neighbouring cities -- Faridabad and Gurgaon -- have witnessed "substantial ozone build-up" from February to May, a green body claimed on Thursday, cautioning that it was e

As the world grapples with the challenge of climate change, a top Indian scientist has called for the opening of more Indian research stations in the Arctic.

NEW DELHI: Not just extreme heat, air pollution levels are also peaking in many parts of the city.

The Montreal Protocol was designed to protect the stratospheric ozone layer by enabling reductions in the abundance of ozone-depleting substances such as chlorofluorocarbons (CFCs) in the atmosphere. The reduction in the atmospheric concentration of trichlorofluoromethane (CFC-11) has made the second-largest contribution to the decline in the total atmospheric concentration of ozone-depleting chlorine since the 1990s.

PARIS: The decline in the atmosphere of an ozone-depleting chemical banned by the Montreal Protocol has recently slowed by half, suggesting a serious violation of the 196-nation treaty, researchers

Air pollution is not only injurious to human health, but also to plant life.

The Ministry of Environment is set to conduct a detailed energy efficiency market survey that will inform new policy aimed at introducing new non-pollutant cooling technologies by restricting impor

The ozone layer - which protects us from harmful ultraviolet radiation - is recovering at the poles, but unexpected decreases in part of the atmosphere may be preventing recovery at lower latitudes

The impact of black carbon, emitted by aeroplanes, on monsoon, glaciers and ozone layer is "uncertain", but its sustained emission could lead to warming of the atmosphere at 10-12 km altitude, the
