Good morning,
Sometimes the cure can be worse than the disease. In a
scramble to reduce greenhouse gas emissions and increase
renewable fuel sources, biofuels are being pushed aggres-
sively in the European Union. But some experts are saying
that the consequences of shifting so much agricultural
resources to biofuel crops may be more harmful to the
environment than the fossil fuels they would replace.
Scroll down for some excerpts detailing these problems in
an article from guardian.co.uk

In an outspoken attack on a policy which comes into force
next week, Professor Bob Watson, the chief scientific
adviser at the Department for Environment, Food and Rural
Affairs, said it would be wrong to introduce compulsory
quotas for the use of biofuels in petrol and diesel before
their effects had been properly assessed.
Under the Renewable Transport Fuels Obligation, all petrol
and diesel must contain 2.5% of biofuels from April 1.
This is designed to ensure that Britain complies with a
2003 EU directive that 5.75% of petrol and diesel come
from renewable sources by 2010.
But scientists have increasingly questioned the sustaina-
bility of biofuels, warning that by increasing deforestation
the energy source may be contributing to global warming.
John Beddington, the government's current chief scientific
adviser, has already expressed scepticism about biofuels.
At a speech in Westminster this month he said demand for
biofuels from the US had delivered a "major shock" to world
agriculture, which was raising food prices globally. "There
are real problems with the unsustainability of biofuels,"
he said, adding that cutting down rainforest to grow the
crops was "profoundly stupid".
Britain will move cautiously in its battle with Brussels
because Jose Manuel Barroso, the European commission
president, is championing the 10% target for 2020. Barroso
this month dismissed as "exaggerated" claims that biofuels
can lead to increases in food prices and greenhouse gas
emissions due to deforestation. But other members of the
commission and other countries, including Germany,
sympathise with Britain.
