US made green house gases sources

  1. Darrel,
    And two of the worst polluters are located right in Indiana's eighth congressional district. Who does Larry Bucshon take money from? Peabody Coal and Duke Energy...

  2. Ron, Well hopefully the new EPA rules from a couple weeks back mandating in the next few years installation of more scrubbers to clean up the smoke will not be overturned by a new mormon president.

  3. Just curious, but where are auto emissions and cow flatulence on the chart?

    1. Squatlo, good catch, this chart has let cars and cows get into one of these other pie sections. Cows make less than 3% of it, belching is almost all of that, farts not much, if that makes you feel better that your breathing second hand cow burps mostly. Transportation is tricky, I find lots of numbers, from 27% down depending on lots of "stuff". Cars only, all forms and types of motion of people and commerce, is it counting all greenhouse gasses or just one or two or whatever. I did find interesting something easy to distort, data on type of vehicle and how much pollution they make. SUV's make less than compact cars. But, big but, this much thrown around finding is looking at the whole fleet. It turns out the average SUV is not very old and equipped with latest gadgets, while the average compact is much older, in some parts of the country people keep patching them up and limping along with them sputtering out smoke, it's a function of wealth. The cars in the US make 30+% of car produced greenhouse gases by cars all over the world, even though we have far less than 30% of the worlds cars. Reason, poorest mpg standards of any large market nation.

    2. Squatlo, I found the EPA site that issued this graph. It was taken from a study which did not include transport or agriculture. I could not find the one which includes everything, I lost interest. The choices are many, with various perspectives of blocking out one or more fields to compare the others.
