There are technologies being devoted that will allow ethanol to be produced from arable waste, so that land could feasibly be used for food and fuel. I don't know what the figures are on that, but it has to be closer to sustainable.
But, really, there's only one answer- use less fuel. Drive less, in more efficient cars, cycle, walk etc. etc.
