Biofuels dont reduce Co2 to desired levels

While the European Union has set its target of meeting its target of meeting its needs of transportation fuel to the extent of 10% through bio-fuels by 2020, London thinks differently.

The mayor of London, Ken Livingstone, who was in Delhi on Tuesday, is of the view that bio-fuels do not reduce the carbon dioxide emission to the levels desired. London has prepared its own Climate Change Action Plan to deal with the intention of reducing 60% of the citys emission by 2025, he said.

According to the action plan, London is to promote low-carbon vehicles with hybrid fuel system which cut transport emissions by up to 4 to 5 million tonne .Carbon dioxide emission from road transport would fall by as much as 30% if people simply bought the most fuel efficient car in each class, the action plan said.

Livingstone has sought Delhis partnership in exchange of ideas in making life in both the cities more clean and green. He has initiated the Large Cities Climate Leadership Group - C40 - bringing together 40 of the worlds largest cities to develop, procure and adopt low-carbons solutions showing best practices among cities. The C40 partners with Bill Clinton Foundation and the Climate Change Initiative.

Londons example of refusing to use bio-fuels in transportation and resorting to other option is relevant in context when India has proposed to launch a massive bio-fuel programme and its use as auto-fuel.

Leading scientists like David Pimentel of Cornell University, Tad Patzek of University of California, Florian Siegert, managing director, Remote Sensing Solutions GmbH , Munich, Mario Giampietro of Institute of Environmental Sciences, Barcelona and Helmut Haberl of Klagenfurt University, Austria have questioned the very basis of the contention of the IPCC report that bio-fuel programme causes a reduction in carbon dioxide emission.

Explaining the action plan, the senior adviser to the London mayor in climate change and sustainable transport, Mark Watts said : Global experiences suggest that bio-fuels do not reduce the carbon dioxide emissions to the extent desired. We in London have, therefore, launched a programme to convert the entire 8,000-bus fleet to diesel-electric hybrid vehicles. We expect entire conversion of our bus fleet by 2012.

When asked to comment about Delhis CNG-run buss fleet, Watts said : Emissions are not reduced to the desired extent.
