How green are our cities? The key number in measuring that now is the per capita emission or how big a carbon footprint an individual leaves. The developed world pegs lndia's per capita emission at 1.7 tonnes. But a study by a non-profit organization of 40 Indian cities says it is much lower at less than 1 tonne. The worst big city in India is Kolkata, at 1.83 tonnes, but it is...

More suggestions that biofuels are not an environmental free lunch ONCE upon a time, biofuels were thought of as a solution to fossil-fuel dependence. Now they are widely seen as a boondoggle to agribusiness that hurts the environment and cheats taxpayers. A report commissioned by the United Nations endorses neither extreme. It gives high marks to some crop-based fuels and lambasts others. Meanwhile, two papers published in Science, a leading...

The new alliance, with India as a 'deal-maker', will do little to cut emissions to anywhere near the desired levels As the clock ticks to Copenhagen, how low is the world prepared to prostrate to get climate-renegade US on board? Is a bad deal in Copenhagen better than no deal? The US’ intentions are not good for the climate. It has proposed that it will not take international commitments but...

The rich countries blame India and other developing nations for the world's rising emission levels. Here is proof that the boot is on the other foot. Fresh data released by the UN Framework Convention on Climate Change says greenhouse gas emissions from the rich nations increased by 12.8% between 1990-2007, the latest period for which figures are available. While the industrialized countries are now gunning for India and China to...

The agricultural sector is both an emitter of greenhouse gases and a victim of global warming. Technological change, water utilisation and cropping pattern in agriculture have implications both for emission reduction and adaptation. While hydrocarbons and raw material-based industries contribute to global warming, their productivity is not necessarily affected by the phenomenon, as is the case in agriculture. Agricultural production impacts climate change and, in turn, is impacted by it....
