The Inexact Science of Carbon Neutrality 302

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?'"

    The real world doesn't work that way. In the real world, local effects are just as bad as global effects, and there's no guarantee that opposite local effects in two places will ever actually cancel each other out. It's a nice way to help people feel good about themselves, but in the grand scheme of things, it is naive to think that carbon offsets, no matter how large, can undo the damage of the carbon you shouldn't have emitted in the first place....

          From wikipedia:

          Although contributing to many other physical and chemical reactions, the major atmospheric constituents, nitrogen (N2), oxygen (O2), and argon (Ar), are not greenhouse gases. This is because homonuclear diatomic molecules such as N2 and O2 and monatomic molecules such as Ar have no net change in their dipole moment when they vibrate and hence are almost totally unaffected by infrared light.

The fact that some CO2 is a necessary component of our atmosphere has very little bearing on whether some larger amount is better, worse, or about the same.

    Some credits are better than others. There are several verification programs in existence. In the USA, I am most familiar with the Chicago Climate Exchange and the California Climate Action Reserve (CCAR). A lot of projects would have occurred anyway due to profitability or regulations, and GHG credits from these projects are junk. Preserving a piece of forest in a desolate valley nobody could profitably harvest or installing a landfill gas flare where carbon has become too expensive should be considered "business as usual," but unfortunately some accreditation agencies and verifiers don't consider "business as usual" and say there is a reduction anyway. These credits are a scam perpetrated by the seller, the verifier, the accreditor, and sometimes the buyer.

    There are some projects that generate real reductions. For example, capture or methane from manure lagoons or landfills where it is not required by regulation and is not less expensive than carbon treatment or the planting and preservation of trees in an area that would otherwise be harvested. These credits are real reductions.

    The problem is the layman has no idea where their credits are coming from. I'm in the industry, and I can't always tell you the value of a credit.

And that's when the theory applies to something that is entirely academic. When it has serious economic implications, how clear a picture do you think is going to develop?

    Ok, most comments are heavily critizising carbon credits, so, risking being bashed, I will write a little about the goods of carbon credits, from a perspective of a peruvian citizen. First, of course its not the ideal solution. Many in slashdot want either ideal or nothing. The best solution is for factories to stop polluting. However, in the real world, this is not currently achievable, as most of us continue to buy products that we ask those factories to make for us. Factories are just the intermediaries, we are the ones that demand more stuff. if you really want *factories* to stop polluting, *stop buying* their stuff, reduce, reuse, and recycle, and have less kids. That said, the Kyoto protocol is at least a starting point, which formalized the mechanism for carbon credits. its a way for factories to continue polluting, BUT with two new advantages: 1) Some countries now put a price on that pollution, and factories now must pay for that, or must reduce their pollution. The best incentive is always money. In Europe this does work. And 2) not only do they have to pay, but that money goes towards projects that are good for the environment. As an example, here in Peru where I live, its actually a good business to plant and maintain a forest, because we get $ from carbon credits. This would have been impossible before Kyoto, and I can tell you first-hand that nobody gives a crap here about forests unless they receive some money in exchange, and the government does nothing to stop deforestation, so its left to private business to do something. In fact our rainforest is being heavily devastated mostly by coca plantations that destroy it. At least the carbon credits offset that a little bit. Hopefully as the cost of a carbon credit goes up, so will the business of making and maintaining forests. I also have a lot of criticism for carbon credits, but nobody was saying what its good for, so I had to.
