Yesterday was the last day of the Auto Expo 2012 in New Delhi. It should have been the first day of ending our obsession with cars and instead, realise what this fascination is doing to our insides.  Over a decade ago, Delhi was a heroic city. It had successfully reduced air pollution by shifting buses and three-wheelers from diesel to CNG. But now, Delhi's residents are choking again. Recently, this paper...

-The United Nations The presence of greenhouse gases in the Earth’s atmosphere last year reached its highest levels since pre-industrial times, a report released by the United Nations World Meteorological Organization (WMO) warns today. The latest edition of WMO’s Greenhouse Gas Bulletin, which places special focus on rising Nitrous Oxide concentrations, also notes that the rate of increase of greenhouse gases has recently accelerated. “Even if we managed to halt our greenhouse gas...

Emissions of harmful green house gases (GHG) from the agriculture sector in India declined 3 per cent in a period of about 13 years to 2007 due to the adoption of advanced farm technologies. CHG emissions declined from 344.48 million tonnes of CO2 equivalent in 1994 to 334.41 million tonnes in 2007, according to the government data. The data has been provided by Indian Network for Climate Change Assessment (INCCA), a programme...

The European Commission’s decision to exclude two key ozone-depleting gases from the purview of carbon trading from 2013 would have negative implications for global warming. The two industrial emissions marked for this purpose are Hydrofluorocarbon-23 (HFC-23), essentially trifluoromethane, and Nitrous Oxide. These are highly potent greenhouse gases (GHGs) that together account for the bulk of the trade under the EU’s emission trading system, which is, by far, the world’s largest...

The main greenhouse gases have reached their highest concentration levels since pre-industrial times, a United Nations climate research body said today. The World Meteorological Organization’s (WMO) 2009 Greenhouse Gas Bulletin warns that carbon dioxide, methane and Nitrous Oxide have all increased their presence, increasing their burden on the earth’s atmosphere. “Greenhouse gas concentrations have reached record levels despite the economic slowdown. They would have been even higher without the international action taken...
