Some facts on Brazil, Alcohol, Sugar, GHG & Government Intervention:
1) The global price of sugar is near an all time high (near 30 cents per pound).
2) Thus, production of alcohol was reduced to make more sugar (and also in Brazil there was excess rain, which both lower the sugar content in the cane and made mechanical harvesting more difficult and slow. India, second largest producer, had just the opposite problem – too little rain. This is why sugar is so expensive now.)
3) The large elevation in the price of fuel alcohol in Brazil removed its cost advantage compared to gasoline. Thus, many fex-fuel cars started to use gasoline. This caused the price of gasoline to increase 4% and PetroBras to stop exporting any. (PetroBras is majority owned and controlled by the government. This termination of exports was partially an election year measure to keep voters from becoming angry.)
4) Also to help return the price of alcohol to competitive against gasoline, the government lowered the alcohol content of gasoline. Normally it is 25% but now only 20%. – this is like a 7% increase in the supply of alcohol fuel. That helps keep both fuels less expensive.
Now a few facts about land used for alcohol and other agricultural products & activities in Brazil:
Of the total 297 million agricultural hectares in Brazil*
2% are used for growing sugar cane.
4% are used for growing corn.
6% are used for growing other crops not listed here.
7% are used for growing soy beans
80% are used for growing pasture grass, mainly for beef production, or are abandoned pasture. Sugar cane is a grass and will grow most anywhere grass will grow. Only by recovery of the abandoned pasture, the cane production in Brazil could be increase 500%.
Thus the often stated claims that alcohol is reducing food production is nonsense at least in Brazil; but that may be true in the USA. The production of beef is becoming more concentrated, so that is freeing up pasture. For example in the state of Sao Paulo, which produces nearly half of all the sugar cane, in the one year from 2004 to 2005 the number of cattle went from 128 to141 steers per square kilometer.
Brazil has the world’s largest beef herd, but as it is grass feed the price is lower than feed lot cattle.I do not know recent data, but before the recent draughts in Australia, the value of Australia’s beef production was slightly greater than that of Brazil’s larger herd. Perhaps now both by numbers and by value, Brazil's herd is number one in the world.
The belched methane by this herd is a much greater contribution to Green House Gases than all the cars and power plants in Brazil! (Partially because more than 85% of Brazil’s electric power is hydro power and about half the fleet runs on alcohol (a slight negative contributor to GHG production)
If you want to help reduce GHG production, eat less beef.

* I am almost sure that the huge amount of land growing trees for paper pulp is not included in this 297 million agricultural hectares. Brazil's is the world's lowest cost producer fo pulp for paper, but may not be the largest producer as Canada and Scandinavia are closer to the main markets.

Here is link about India's power production problems cause by the lack of rain/ lack of cane. (In both countries, the crushed cane contributes significatly to the national electric grid. This simple power production will be an alternative use that celulosic alcohol will need to compete with. Both for bagesse and other fiber sources. Bagesse is the cheapest thermal fuel as not only is it free, like wood scraps, it is also already at the thermal power plant.):

Where you can read:
"In years when cane availability drops, power plants find it difficult to operate at full capacity. Low or lack of cogen power has another effect. Sugar companies have started importing and refining raw sugar to make up for the cane shortfall. Without power, they cannot refine sugar either. So companies are embarking on a new path; they are seeking to become power producers using coal. ..."
AFAIK, Brazil is never short of crushed cane and gets nearly 10% of its power from buring bagasse. It also supplies all the energy need for distilation of the alcohol. Thus, in country that uses fossil fuel for power (like India) alcohol fuel for cars is a significantly negative contributor to GHGs as the bagasse produced power displaces the burning of fossil fuels for power.
