EVERY time an American family decides to take its car out, the resulting carbon dioxide adds to the existing stock in the atmosphere for at least a hundred years. When the polar cap cannot bear the trapped heat, it will melt and drown the distant country of Maldives or Bangladesh. …
THE BRANDT Commission in 1980 had called for a world "based less on power and status, more on justice and contract; less discretionary, more governed by fair and open rules". Shridath Ramphal renews that appeal, on the road to Rio, but passion is not the sole basis of his plea. …
CALL IT a guilty conscience or call it uncanny business sense. But Toyota, Japan's largest car manufacturer, is busy trying to produce a genetically-engineered tree which can absorb larger amounts of carbon dioxide than its more natural counterparts. The research programme first aims at identifying and cultivating existing tree species …
FOUR buses of the Chola Roadways Corporation at Nagapattinam in the coastal district of Thanjavur are different from the rest of the fleet. They are fueled by a half-and-half mix of compressed natural gas (CNG) and diesel. The pilot project is the first of its kind in the country. India …

LARGESCALE use of CNG as an automotive fuel can give breathing space to people in the heavily-polluted metropolitan cities of India. Motor vehicles are said to be responsible for 60 per cent of the total pollution load in Bombay, some 12,000 tonnes of pollutants daily, including 40 tonnes of lead. …
THIS fortnight the European Commission unveiled a plan, which its environment comissioner, Carlo Ripa di Meana, called "revolutionary" to staise a carbon dioxide emissions at their 1990 levels by the year 2000. Half of this reduction is to be achieved through a tax on carbon fuels - of $3 on …
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 …
Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf ecosystems) are thus important both to the regional enhancement of productivity and to the global flux of C that is observed in land-margin ecosystems. …
The UN sponsored discussions to prepare a global convention on climate began in February in USA. The aim is to prepare a legally binding convention to curb gaseous emissions leading to a much feared climate destabilisation. This convention is being seen as the world's greatest commitment to the environment and …
BIOLOGY Yellow pigment clue to evolution Bilirubin, responsible for the yellowish tinge in the skin, eyes and nails of jaundice patients, has for the first time been identified in plants. The pigment was discovered in Strelitzia reginae Aiton, commonly know as the Bird of Paradise plant. It is indigenous to …
As the Durban COP enters the homestretch it is worth stepping back a few years – to COP-13 at Bali in 2007. For it is the Bali COP that led to the creation of the Ad-hoc working groups for Long-term Cooperative Action (AWGLCA) and for the Kyoto Protocol (AWGKP), which …
The theme of the Rio + 20 Conference was "Green economy in the context of sustainable development and eradication of poverty" and it has not been possible to the find common ground in the serious differences over what constitute economic growth and human wellbeing – ‘the future we want’. Humans …
The underlying issue is not trade rules but the global climate regime The concerted opposition to the EU push towards forcing foreign airlines landing in Europe to become a part of its emissions trading scheme has led to an unexpected development, whose implications extend to setting the global climate agenda. …
The new climate regime will lead to commitments only for developing countries, because the United States, which did not ratify the legally binding commitments under the Kyoto Protocol, continues to insist on a framework with nationally determined emissions reductions monitored at the global level. The unresolved issue is multilateral agreement, …
The task for global governance in dealing with climate change is to focus on the interconnectedness between carbon dioxide emissions, standards of living and global ecological limits. The interdependence between countries makes the global commons, or carbon sinks, a shared economic resource as well as an unprecedented global environmental crisis, …
Very different global rules are needed for human wellbeing Averting climate change does not need emission reduction pledges, timetables and a common legal framework. Climate governance cannot be considered only in terms of environmental damage because it is now a part of the economic debate around the competition for scarce …
For growing economies the stress has to be on patterns of natural resource use and not on the status of natural resources; that is, dealing with the causes rather than the symptoms of the problem of climate change. The time has come for rapidly growing Asia to distinguish between the …
Car industry's efforts to dilute standards approved by PMO will significantly reduce fuel savings The desperate bid of the Indian car industry to reopen and dilute the proposed fuel economy standards after it was approved by the prime minister’s office (PMO) has shocked all. This violates the sanctity of the …
With relations between countries now being shaped by geo-economics rather than geo-politics, an emerging issue is to what extent the United States, China and India, all populous countries and top tier economies, see their national interest in giving a new meaning to words like “responsibility”, “development” and “growth” by shifting …
