    A herd of cows belches out more climate-changing gas than a family car, a university researcher has said.
    Andy Thorpe, an economist at the University of Portsmouth, explained that 200 cows burp the annual amount of methane equivalent to the energy produced by a family car being driven 111,850 miles (180,000km).

    The amount of methane produced by a herd was the same as the carbon dioxide (CO2) emissions produced by a car burning 21,400 litres of petrol, he said.

    Then, the answer is, to knock down a hurd of cattle once a year.

    A bit like a carbon offset?

    Not difficult where I live, but might be for some of you lot living in the smoke!!

    the maths quoted above would work if only they were a fair comparison....

    so if 200 cows give out the same amount of greenhouse gasses as one car driven over a hundred thousand miles, that means each cow gives out the same methane in one year as one car driven about 500 miles


    A reasonable guess would be that there are about 2 million dairy cattle in the uk whilst there are over 32 million cars (2003 figures) driving an average of 8000 miles per year

    So one "average" car turns out the same amount of greenhouse gasses as 16 cows each year and for cows to overtake cars as polluters there would need to be some 512 million of them in the UK alone - that's an awful lot of cows

    perhaps it's best to look for another scapegoat?

    Of course, it's late and these figures could be wrong - I'll look at them again in the morning :)

    This is a notable greenhouse gas issue but the gas is different from what cars produce, in some places they actually collect the methane and use it for heating or something. The CO2 from our cars would be useless even if we could collect it.

    One also has to figure that methane is a lot more potent a greenhouse gas the CO2 so the effects are potential worse than hawk20 OP'd.

    Could it be that Hawk has posted a humorous post and we are being tgoo serious, or is it a flawed serious post?

    If it is serious, then the methane is only being assessed as burps....... Surely there are two orifices that emit this gas?

    Andy_K
    Do we double the figures because of the two escape hatches?

    Regards

    Not entirely serious, I would suggest. :) :) :)

    Though the report I posted is apparently factual.

    For what it's worth: altogether there are about 10 million cattle in the UK. There are a little over 2 million adult dairy cows in the UK, a little under 2 million adult beef cows, and about 6 million younger animals

    I have heard this before too abiut methane and cows. Give up the beef and buy an SUV comment, plenty of cars emit high levels of CO2, not just the high sided ones. BMW X5 3.0sd is under 225g/km CO2 ;)

    However methane breaks down more readily in the upper atmosphere than CO2 so whilsts methane is a more potent greenhouse gas, its around for much less time to act as a green house gas than CO2.

    However the quantities of methane released is alarming, and it puts into context tail pipe emissions of CO2.

    Lets not forget the energy used in the production (UHT for instance) and transportation of milk. Then there's the cooking of all those steaks. Cows have a lot to answer for.

    I just polished off roast beef sandwiches. They were yummy. Life's too short to worry about the environment :D

    I wonder how much gas we as humans omit? Co2 and methane... I know some people that probably emit more gas thanj my car does.

    We could round up all the people that emit more CO2 than average and give them an ultimatum. People like joggers and cyclists etc.

    If cyclists got off the roads and on the bus or train they'd emit less CO2.

    Ban cyclists I say. :bannana:
