Grilling the Citizens

When I first saw this story I though it was satire or a hoax, but it's real (from Special Report):

Local officials in Belgium's French-speaking region of Wallonia have a new tool in the fight against global warming. They have approved a tax on barbequing. Experts say that up to 100 grams of carbon dioxide are produced during barbequing.

So Wallonians will have to pay 20 euros — about 27 dollars — each time they fire up the grill. And the authorities aren't kidding around when it comes to enforcement. Officials say they will use helicopters with thermal sensors to detect illegal grilling.

Do they have emission-free helicopters over there? I wonder how many barbeques it would take to equal a couple hours of turbine helicopter operation?
