I think this is not as easy a calculus as one might imagine. Heirloom furniture is in some ways less sustainable than Ikea products. I am not sure there would be enough sustainable hardwood in the world to meet demand at the scale of Ikea. People have different furniture needs than they did decades ago, and in terms of weight, logistics, material use, Ikea are quite efficient.
The complication is EXACTLY why we need to be even more in panic and hair-on-fire about environmental issues. A colleague did some analyses for the life cycle emissions of refrigerants. The complexity in the process was absurd, and basically intractable without simplifications. How much indirect CO2 emissions are caused by an inefficient compressor? How much does it depend on how you generate electricity? Which count…
Main problem is figuring out how to incorporate emissions into price signals.
