-The United Nations   Fast and relatively short-term action to curb soot and smog could improve human health, generate higher crop yields, reduce climate change and slow the melting of the Arctic, according to a United Nations-backed study released today. The study, compiled by an international team of more than 50 researchers and coordinated by the UN Environment Programme (UNEP) and the World Meteorological Organization (WMO), “complements urgent action needed to cut...

Renewable energy sources such as solar power, wind, biomass and hydropower could meet nearly 80 per cent of the world’s energy supplies by 2050 if governments pursue policies that harness their potential, a United Nations-backed report released today says. The findings of more than 120 researchers working with the Intergovernmental Panel on Climate Change (IPCC) indicate that if the path of renewable source is fully followed, greenhouse gas emissions could stay...

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...

Dramatic cuts in industrial emissions of the global warming greenhouse gases that threaten to drastically change Earth’s climate are achievable in both developed and developing countries at acceptable cost with the right policies, the United Nations reported today. In a series of studies, the UN Industrial Development Organization (UNIDO), an agency mandated to promote sustainable industrial development in developing countries, highlighted the need to combine energy efficiency, renewable energy and the...
