STERKSEL, the Netherlands — The cows and pigs dotting these flat green plains in the southern Netherlands create a bucolic landscape. But looked at through the lens of greenhouse gas accounting, they are living smokestacks, spewing methane emissions into the air.

The farm at Sterksel makes electricity for itself and for sale, and sells carbon credits.

That is why a group of farmers-turned-environmentalists here at a smelly but impeccably clean research farm have a new take on making a silk purse from a sow’s ear: They cook manure from their 3,000 pigs to capture the methane trapped within it, and then use the gas to make electricity for the local power grid.
