Judgment of the National Green Tribunal, May 27, 2025 in the matter of Sumit Saini Vs Shree Ram Steel Industries & Others. Sumit Saini, resident of village Damla, District Yamuna Nagar, Haryana had sent a letter petition dated May 14, 2022 to the NGT. The application said that around 25 …

Chew and spew

METHANE is the second most important contributor to global warming after chlorofluorocarbons (CFCs), with a 100-year global warming potential (GWP) of 24.5. And domesticated ruminants (cattle and camels), contribute about 20-25 per cent of global methane production annually. Of this, 85 per cent is added to the atmosphere when the …

Drilling down the dumps

SINCE July last year, the municipal garbage dump at Gladokvarn, outside Stockholm, has been yielding gas at the rate of 22,000 in per day from gas wells up to 20 in deep. The gas is carried via a 13 km-long pipeline to a 5 mw heating plant which, in turn, …

Gas on demand

NATURAL gas is formed under the earth's surface when organic debris, under conditions of high temperature and pressure breaks down into methane and other smaller hydrocarbon molecules. Similar conditions simulated in the laboratory did not yield the requisite percentage of methane in the end product. Whereas natural gas contains 80 …

Heating pools

BEAVERS, known for their ingenuity at damming small streams using branches, are unwittingly contributing to global warming (New Scientist, Vol 142, No 1931). Beaver ponds flood low-lying areas and, like wetlands, cause the decay of submerged vegetation, which produces the greenhouse gases methane and carbon dioxide. But Joseph Yavitt and …

Methane`s metal link

OVERTURNING traditional theories on the natural production of methane, a major component of natural gas, a team of US researchers now says that metals such as nickel and vanadium present in the sedimentary rocks where natural gas is formed, facilitate methane formation. Till recently, it was widely believed that methane …

Methane halt

METHANE, a key greenhouse gas that has been growing alarmingly in the atmosphere, suddenly stopped in its track beginning 1992. Although previous studies had shown that the rate of methane increase slowed down in the '80s, a new analysis carried out by Edward Dlugokencky of the US's National Oceanic and …

As deadly as thermal power

RECENT Canadian studies suggest that hydroelectric power generation may, in some cases, be a major source of greenhouse gases, such as methane and carbon dioxide, and so be as polluting as thermal power generation (Ambio, Vol 22, No 4). The gases are produced, explain John W M Rudd of the …

Methane on the decline

SCIENTISTS say the increase in the atmospheric concentration of methane -- a major greenhouse gas -- is fast levelling off (New Scientist, Vol 140, No 1991). Evidence of a halt in methane rise comes from measurements of atmospheric gases made at 26 stations around the world. In the 1970s, the …

Beware the technology bait

JOINT implementation was the main point of discussion at the recent meeting of the intergovernmental committee on climate change in Geneva. The idea of joint implementation has been promoted primarily by industrialised countries seeking ways to reduce their greenhouse gas emissions. Unable to face the politically difficult choice of reducing …

Sun plays marginal role in global warming

TWO RECENT climate studies have found that while changes in solar radiation do contribute to global warming, this effect is small as compared to that of human-made greenhouse gases. The increase in the annual average global temperature at the earth's surface was as much as 0.8o C between 1880 and …

Pollution, not rice accumulated methane

THOUGH a great deal of fuss has been raised in scientific circles over methane production by rice paddies and cattle in the developing world, which is likely to heat up the earth, the atmospheric chemistry of methane is still a grey area. Scientists-are finding that it is quite possible that …

Atmospheric chemistry shifts blame around

Hot aluminium THE aluminium industry is responsible for spewing out two potent greenhouse gases - CFC-14 (tetrafluoromethane) and CFC-116 (hexafluoroethane). In terms of their global warming potential, they are over 8,000 times more effective than carbon dioxide, their atmospheric lifetime being over 10,000 years, according to Dean Abrahamson of the …
