The widening of the M6 will cost £3bn or £1000 an inch. What does this fact tell us about the government’s green priorities? Are we really leading the world on climate change as the government likes to claim? In the article below Ashley Seager (Economics Correspondent for the Guardian) looks at these issues and argues that we may be the poor man of Europe when it comes to ‘green’ policies.

In its first report on the impact of bio-fuels, the United Nations (UN) has warned that such fuels may increase poverty in developing countries and have a wider environmental impact than has in the past been suggested. With oil prices at a record high and with climate change pressures, much of the developed world has adopted targets for bio-fuels, but environmentalists have warned that the rush to grow the raw materials for bio-fuels may be more damaging to the environment than the fossil fuels they will replace.

You do perhaps need to check the date for this story, but once you have established that it wasn’t written on April 1st, you can start to take it a little more seriously. An alliance of an American oil company and food producer is to turn pig fat into diesel fuel. The fuel will apparently have the same chemical properties as diesel but a lower carbon dioxide content and zero sulphur, so should be beneficial for the environment the companies argue.
