The Inexact Science of Carbon Neutrality

Posted by timothy on from the these-are-not-weight-watcher-exchanges dept.

snydeq writes "Sustainable IT's Ted Samson raises questions regarding the purchasing of carbon offsets, a practice growing in popularity among tech companies such as Dell, Yahoo, and Google in an attempt to achieve 'carbon neutrality.' Essentially financial instruments, carbon offsets enable companies to invest money in sustainable endeavors in an attempt to counteract the carbon footprint they incur conducting their business. But as a recent article in the Wall Street Journal shows, measuring the value of these carbon offsets is tricky business, as some recipients of offsets say the results of their sustainable efforts would be achieved regardless of any one company's investment. 'The question of whether carbon offsets hold value just scratches the surface of the overall carbon-neutrality question,' Samson writes. 'For the time being, there isn't even a consistent approach to measuring an organization's carbon footprint in the first place. And if you don't know how much CO2 you're responsible for, how do you know how much offsetting is necessary to become neutral?'"

      Are you competent to evaluate controversial issues in high-energy physics?

      Well yes, I am but that is not really the point. The point is are scientific methods being applied? Although I am high energy physicist and not a climatologist, it should be possible for a climatologist to provide convincing and conclusive evidence that humans are unambiguously the cause of the recent global warming. You have to be an expert to come up with the data and its interpretation but if you cannot explain the resulting evidence to a fellow scientist, even one outside your field, there is something wrong.

      The problem with global warming (as I understand it) is that there is conflicting evidence as to the cause. So far I have not heard an expert on either side of the debate come up with convincing arguments to explain the other side's evidence. The conclusion I am therefore forced to reach is that we do not understand why the Earth is warming at the moment. Having had a chance to talk with an expert in a climate related field a couple of weeks ago this was his conclusion too.

      So, I would disagree strongly with your '99%' concensus number and, while we should certainly respect and listen to the experts in the field, that does not mean that we cannot question them, especially when there is no concensus.

    I'm not sure about carbon neutral, but we've seen a our power bill go down by 90%. Still, it will take about 4 - 5 years to recoup the investment, but if you view it as a sunk cost, it's freed up a lot of cash flow.

      We didn't even bother to consider it because we didn't do it to be "Green". We did it because we had the cash on hand, the tax write off for the investment expired in December, and by switching to solar we freed up enough money to pay for another developers salary.

  3. The Indulgence of Global Warming Religion by geoffrobinson · · Score: 4, Interesting

    Global Warming has all the elements of caricatures of religion.

    Sin? Carbon.

    Original Sin? Capitalism/Industry.

    Which leads us to carbon offset. Yes, just like Roman Catholic indulgences. Except they produced something useful. The Sistine Chapel.
