The Montreal Protocol shows what is possible when science, diplomacy, and business cooperate to implement international environmental agreements. When the people became aware of a hole in the ozone layer over Antarctica—and damage to the protective layer of atmosphere around the world—leaders around the world coordinated action on ozone depleting …
It’s a Catch-22 situation. How does one rate an industry where the pollution is minimal at the production plant and peaks the moment the product leaves the factory gates? How does one rate an industry that is the mother of all chemical industries? How does one rate an industry that …
by the 2030s, climate change could become the main factor leading to ozone loss, surpassing even industrial products such as chlorofluorocarbons (cfcs), says a new National Aeronautics and Space Administration (nasa) study. While attributing this to changes occurring in water vapour and temperature in the upper atmosphere due to rising …
India is obliged under the Montreal Protocol to gradually stop the use of ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs), which cause unimaginable damage by burning a hole in the Earth's stratospheric ozone layer. The industrialised countries have already phased out some of these substances. The first deadline for India …
When the time comes to phase out the manufacture of ODS in India, like other developing countries, the country has three options. They can either buy alternative technologies from the West or fund and develop indigenous alternatives or shut shop. Each ODS has a range of substitutes. CFC manufacturers can …
WHILE the manufacturers of ODS hit their first deadline as far away as 2010 for the users of these chemicals the clock is ticking at a much faster pace. Those using chlorofluorocarbons (CFCs) in their products will have to stop selling, stocking, exhibiting for sale or distributing foam, refrigerators, mobile …
four chemicals that are thought to cause no damage to the ozone layer may be destroying the protective layer of the Earth, a new research suggests. The most harmful of the four is n-propyl bromide
A new range of substances to replace ozone-depleting substances like chlorofluorocarbons and hydrofluorocarbons, which are banned under the Montreal Protocol, are doing more harm than good. These alternative substances, such as n-propyl bromide and halon-1202, may also have the potential to damage the ozone layer. Although these alternative chemicals, used …
The UN Environment Programme (UNEP) recently launched the first ever online halon trading scheme. Halons are gaseous halogen compounds used to extinguish fires and they are three to 10 times more damaging to the ozone layer than chlorofluorocarbons. The online service seeks to promote responsible management of these chemicals on …
Scientists from Imperial Collegeukhave come out with the first observed evidence of increase in greenhouse effect on Earth between 1970 and 1997. Previous studies in this area have depended on theoretical simulations because of lack of data. Howeverthe researchers at the Imperial College reached their conclusions after analysing data collected …
godrej appliances limited (gal) has begun producing India's first refrigerator that uses hydrocarbons (hcs). The company carried out research for four years in coordination with the ministry of environment and forests and two companies based in Switzerland and Germany before launching their new product. The product was launched on January …
global warming over the next century could turn out to be much worse than previously estimated, says the latest report of the uk Met Office's Hadley Centre for Climate Prediction and Research. Even if greenhouse gas ( ghg ) emissions are stabilised (which would require an overnight cut of 60-70 …
once again, a half-hearted attempt has been made by the Indian industry to address the issue of surviving in a global market where businesses are driven by sound environmental practices. At a workshop
it is time to take out sun creams, ultraviolet protective sunglasses, wide brimmed hats and clothing with long sleeves because the largest ever ozone hole over Antarctica has just been detected by the us National Aeronautics and Space Administration ( nasa) . The ozone hole over the Antarctic is the …
the deadline for concurrence with the Montreal Protocol is fast approaching. In India confusion reigns supreme. Neither the government nor Indian industry is sure of what course to pursue. Both are baffled about the options available for technology transfer to help phase out chlorofluorocarbons ( cfc s). Under the protocol …
EACH year, millions of tonnes of toxic aerosols from Asia travel across to the Pacific Ocean, according to a study conducted by researchers at the University of California at Davis (UCD), usa. According to them, these previously undetected toxic pollutants, which are a result of increased industrialisation in the region, …
india is getting a grant of us $82 million, for gradually phasing out the production of ozone depleting substances (ods) such as CFCs (chlorofluorocarbons). This is the total funding that would be available to India from the multi-lateral fund established for the implementation of Montreal Protocol. The grant, given over …
international efforts to restore the ozone layer are being threatened by a flourishing black market of chlorofluorocarbons (cfcs), said Paul Frasier, senior principal research scientist with the Council for Scientific and Industrial Research Organisation of Australia. According to him, the smuggling is being done on a small scale, but it …
Following two winters of low ozone loss in the stratosphere, the Arctic is likely to have experienced record ozone destruction. The ozone layer thins out during spring but so far has never disappeared. Ozone losses of more than 60 per cent have occured at altitudes of around 18 km. This …
The deadline for completing the tasks laid down by the Montreal Protocol is fast approaching, but India seems to be nowhere near to fulfilling its obligations, warn experts. Under the international treaty signed in 1987, India is supposed to phase out Ozone-depleting substances (ODS) like chlorofluoro carbons (CFCs) by January …
IT IS about the ozone layer. And it is not bad news. Some Australian scientists say if the amount of ozone-depleting substances (ODS) being released is reduced, the most famous layer of the Earth's atmosphere will begin to repair itself. However, before you rush to go tell your friends, bear …
