Interest in tying farming to carbon dioxide credits waning

A once popular program to pay farmers for battling air pollution is waning as industries pass on carbon credits and Congress looks at other options.
...
Credits are currently selling for about 40 cents a metric ton, a price that isn't attracting new farmers. Credits created last year aren't selling, according to the National Farmers Union, which a year ago touted a program enrolment of 2.8 million acres-enough to offset the pollution of more than 300,000 cars.

Now just a few days away, this year's deadline for enrolling land in the credit program will go unnoticed by many.

"This is just a guess, but I'm going to say we did around 100 acres of carbon credits last year," said Scott Kulbeck of the Montana Farm Bureau Federation. "There's no interest now."
