LONDON (Reuters) - Rich countries meeting in Germany this week will agree that they need to confront climate change, but unpleasant tradeoffs are already emerging.
Unless properly managed, a rush to reshape the world's economy to arrest climate change could end up trampling the lifestyles of the rich, the livelihoods of the rural poor, and the earth's most vulnerable habitats.
A tequila shortage is perhaps one of the least-expected results of planting lucrative, "climate-friendly" biofuels -- as Mexican farmers set ablaze their fields of cactus-like agave to make way for corn, a feedstock for ethanol. Biofuels are also blamed for raising food prices and destroying forests.
The result of misguided climate policies could be to undermine public support for action and discourage businesses from buying in.
"Definitely there'll be tradeoffs between climate change and the local environment, and with energy security," said Fatih Birol, chief economist at the International Energy Agency (IEA), which advises rich countries.
"We are not in the luxury of being able to choose from hundreds of energy types."
Just how mankind plans to battle climate change is still sketchy, but one buzz word is "scaling up" -- for example by boosting research into and deployment of clean energy technologies like wind and nuclear power and biofuels
