Outdoor outfitters Timberland have long studied how to reduce carbon emissions in the manufacturing of their famous leather boots to be more environmentally friendly, but researchers discovered that most of those harmful gases weren't released during the manufacturing process.

As Timberland CEO Jeffrey Swartz tells The New York Times, "the vast majority of the greenhouse gases associated with manufacturing leather come from cows in the field." The company is currently researching ways to reduce bovine flatulence — including changing the livestock's feeding habits.
