Tailpipes, cows expand Idaho’s carbon footprint. Greenhouse gas emissions grew 30% from 1990 to 2005, thanks mainly to dairy expansion. Idaho Statesman. By Rocky Barker.

Part of this “increase” is an accounting change — to include methane gas as well as carbon dioxide. Methane is a very potent greenhouse gas and cattle operations, especially CAFOs emit a lot of it.

    Does anyone out there have a peer reviewed source that outlines how these cattle related gas estimates are made? I am not aware of any reports re hard science on this although I do not dispute that the issue is a real one. I just see a lot of claims about methane but never any empirical explanation of how the numbers are determined.

    Dang! You guy’s are going to have to boycott milk and cheese now too.

  3. Mike Post says:

    Can I assume that the absence of any responses to my request means that there is no good data on cattle related methane production?

  4. Maska says:

    Mike, I haven’t had time to check, but there is much good info on climate related science on the Realclimate website. If there are good data on livestock related methane, they probably make reference to the studies.

    Mike Post,

    The United Nations’ Food and Agriculture Organization published Livestock’s Long Shadow in 2007 that takes us through the entire commodity chain and it’s affect contributing to warming gases, depletion of biodiversity, etc.

    If this does not suffice, let me know.

  6. Moose says:

    Does anyone recall awhile back there was a farmer with a large dairy herd who captured the cows meth gas and used it to supplement his energy sources for his operation. If I recall correctly, it did not require a large investment in tech on his part.

  7. Save bears says:

    It was on Dirty Jobs on TV, Mike Row the host visited his farm and helped him with the process, I think the total he spent to convert to Methane was less than 10K

  8. Moose says:

    Bingo..thanks Save Bears…I was wracking my brain trying to remember where I saw it. – gettin too old.

  9. Brian Ertz says:

    yes, the captured methane burnt creates energy and mitigates the contribution to warming gases.

    the ‘anaerobic digesters’ are not difficult to construct, nor is the methane difficult to capture and burn off – boise idaho’s landfill has retrofitted a methane power plant. third world communities use livestock waste w/ anaerobic digesters and burn the methane for cooking stoves and heating. and then of course, there’s mad max ‘beyond thunderdome’

    of course, this conflicts with the animal rights folk – feedlots are perfect sources for production of livestock that lends itself to capture of waste – free range is not. i read somewhere that winter pasture is particularly egregious w/ regard to methane.
