a little climate change philosophy

This caught my eye and I was reminded of Paul Robert's observation in his book, The End of Oil, that its all very well rich nations accepting responsibility for most of the greenhouse gases produced but the biggest threat comes from developing countries and a pound spent on efficiency measures and limiting emissions in a developing country buys you a fuck load more than a pound spent in the UK on the same. This is because here we have already gone down the road of efficiency improvements to get where we are today. But that coal fired plant in China or the diesel locomotives carrying people through Indonesia could be improved and upgraded for relatively little, whereas a redevelopment of the UK network to super-efficient TGV-style trains will cost hundreds of billions. I think Mr Ban should have pointed this out.
