Your pets are part of global warming!

How your pet is contributing to global warming

Turns out that chow you’re feeding Fido and Felix produces a pretty big carbon pawprint.

In a study released Wednesday, a geography professor at UCLA calculated that the meat-based food Americans’ dogs and cats eat – and the waste those pets produce – generate the equivalent of about 64 million tons of carbon dioxide a year.

That’s as much as about 13.6 million cars driving for a year, says professor Gregory Okin in a paper published in the journal PLOS One.

Put another way: Dogs and cats are responsible for 25 to 30 percent of the environmental impact of meat consumption in the United States.

Livestock emit methane, which is the source of about 10 percent of all greenhouse gases. Previous studies have found that Americans’ meat-heavy diet results in the release of 260 million tons of carbon dioxide – the leading greenhouse gas – through livestock production. Okin used similar estimates to calculate how much meat the nation’s 163 million cats and dogs eat and its carbon equivalent.

Okin said he isn’t suggesting Americans put their pets on a vegetarian diet, “which would be unhealthy.” However, Okin – who is allergic to dogs and cats but keeps two fish as pets – said he wants pet owners to consider the climate impacts of pet ownership, particularly as many Americans switch their dogs and cats to high-protein premium foods.

“This was not a study to make anybody feel guilty,” Okin said in an interview Wednesday. “I’m not saying people should go out and kill their animals or feed them something that isn’t appropriate….It was a study just to figure out how big these numbers are, and the numbers are surprisingly large.”

Frank Mitloehner, an animal science professor at UC Davis who specializes in livestock emissions, said the study shows that pets “clearly have an environmental footprint, and it is not a small one.”

But he said almost all of the meat pets consume in their food comes from rendered livestock byproducts. Those are the nasty bits that meat processors would otherwise toss because people won’t eat them.
