I’ve been meaning to put something up about this thing for roughly a million years – as you can see, it’s been almost an entire lifetime (for some small people…) since I last posted. Better late than never. So:
Ken Musgrave at Fast Company design/business mag has made the argument for Why We Need a Globally-Recognized Unit of Green. He cites the complications involved with decisions about materials in the design process – i.e. is ‘virgin’ bamboo a better (more sustainable?) choice than, say, recycled paper. Well, growing bamboo is much less resource-intensive than growing wood for paper, while a recycled product uses less (or no) raw materials. Using recycled materials isn’t “free,” though, given the energy costs of recycling and other inputs that might be necessary to break down the fibers or what-have-you. The choice puts unrelated environmental issues up agains
t each other, as we weigh deforestation versus energy consumption versus chemical inputs, not to mention the carbon footprint of shipping raw materials and finished products… It’s an absurd algorithm, and one you’d probably rather not wade through in the supermarket aisle.
Musgrave proposes a standardized unit that compiles all those factors into a single index. Somebody, presumably a third-party certifier of some sort, can measure each product’s impact in terms of all the aforementioned dimensions, weight them somehow, and generate a single composite measure: “We can even call the labels something catchy–like ‘Greenies.’” I’m picturing the equation of ramified green measures with compounding parenthetical statements:
Paper ((70% post-consumer recycled(recycled using X method(Xmethod requiring 80 tons of chemical Y(chemical Y treated via process A and securely stored in site Q(shipped by truck from Scranton(etc.)))))) –>
= 3 ‘greenies’. Ba-da bing.
In a certain sense this is the same logic as the labels on organic food, certified timber, and so on. I’ve described those things elsewhere as ‘labor-saving devices,’ that is, technologies designed to save us the consumers that difficult labor of making ethical decisions about our purchases. We don’t need to know which farm the tomato comes from, what kind of manure the farmer uses, or anything else about it – if it has the organic label, we have it on good authority that at least some bad agro-things weren’t done to it.
What’s different about the proposed ‘greenies’ is the potential incorporation of everything. Organic standards are (sort of) clearly defined, nowadays by federal statute, but really only in terms of some chemicals that won’t appear in the product. It’s good information, but certainly doesn’t tell you everything you need to know in order to decide exactly which product is really the most green. A bunch of grapes conventionally-grown in Virginia represents the consumption of some nasty chemicals, but how does that compare to the ridiculous carbon footprint of the organic grapes that must be flown in from Chile? Only ‘greenies’ can tell us.
Obviously, this is just a thought experiment, but the places where it runs aground are where it gets really interesting. An auditor looking to assign a ‘greenie’ number to those grapes needs to know how to weigh pesticides against carbon footprint, but that’s a value judgment that would necessarily vary enormously from one person to another. I’m quite inclined toward the idea that local-conventional might be a better net environmental choice than organic-transnational; but my partner has a lot of chemical sensitivities and weights the presence of pesticides quite a lot more heavily than I would. For any set of tradeoffs that our hypothetical auditor would need to weigh, we could imagine a dozen competing perspectives. And that’s just considering the consumers’ values – if we try to include those of producers, laborers, and innocent bystanders? It never ends.
