Brazil's Environment Minister has developed a plan to keep sugar cane plantations out of the Amazon and Pantanal:
The proposal, which must be passed by Congress, comes amid concerns that Brazil's developing biofuels industry is increasing Amazon deforestation.
Environment Minister Carlos Minc said the measures would mean ethanol made from sugar cane would be "100% green".
The government agenda is becoming more environmentally friendly ahead of the 2010 presidential poll, analysts say.
The plans unveiled by Mr Minc would limit sugar cane plantations to 7.5% of Brazilian territory or 64m hectares, and prevent the clearing of new land for the crop.
I could care less if this is being done in advance of an election as long as it's done. The major problem with Brazil, however, is enforcement and I'm frankly, less than optimistic about it.
