Can We Separate GDP Growth And Ecological Limits?

Next time you run into a classically trained economist (happens all the time, right?) start talking with him/her about ecological limits. They might squirm a little, but probably respond as trained: with some zombie-like responses about “decoupling.” What is decoupling? Basically, it’s a concept of being able to continue growing economic output without a corresponding increase in environmental impact.

The overall idea is that improvements in production efficiency allow you to make more with less. Theoretically we can increase our efficiency and make more stuff using the same amount of resources and/or generating the same amount of pollution.

Applying this concept to renewable resources would be incredibly beneficial. We could use wood, for instance, in a more sustainable fashion if we decoupled the economic growth from resource use and did so under the ecological limits of forest regeneration.

As you might have already guessed, there are quite a few flaws with this concept. You might have also noticed that it seems at first glance to have a broad definition. In general, however, there are two types of economic decoupling: relative and absolute. The first type appears to have a cursory chance of working, the latter is fundamentally impossible.
