Reducing the impact of celebrity galas and public events is the latest rage, fueling a $100 million carbon offset industry.

How you calculate the carbon footprint of a Junior Mint is something we're not qualified to say. But it does have us wondering - how much would it cost to offset a backyard barbecue?
