In some sense, anything is "recyclable". What does that mean in reality? How much "recyclable" material is actually reused, how much resource transformation does it take to reuse or recycle? Which economic incentives exist, and are they working? "co2" is a single data point, and of course you can tune the process to minimize one, at the cost of something other. How about all the "rare materials" that are required, and all the other pollutants?

Cars are getting bigger and heavier, people buy more cars than ever, and transportation still becomes more and more individualized. The overall environmental damage continues to rise. All these are sad facts, and there is an abundance of "proof" to be found everywhere.
