As a side note, which I'm sure will raise some eyebrows here, but frankly I could care less about being eco-friendly! Why you scream? because manufactures that make all sorts of products don't care, all they care about is making sure a product doesn't last too long so they can keep us spending our money. For example, in the mid 70's Consumer Reports said that the average kitchen appliance (including washers and driers) lasted 24 years and were repairable, as of 2014 that average is now just 8 years and most are not repairable. If being eco-friendly was so important we should be able to buy products that would last a very long time, longer than they did in the 70's, and be repairable. Do you think that building whatever product 3 times more frequently than 40 years ago is being eco-friendly? No, it's about ripping off consumer. Oh I know, you're doing your part...in your mind yes you are, but in the grand scope of things no you really are not.
I'm not complete ogar, I do recycle but only to the city, I don't go out of my to take stuff to a recycle center the city does that for us, and I use water limiting devices in my showers and sinks. So I too play the game to some extent I just don't go crazy about it nor brag that I commute to work to be eco-friendly on my bike, I do it for me...exercise and relaxation, not for the earth.
And in regards to bikes, a carbon fiber bike is LESS eco-friendly to make than making a steel bike. The difference is that most CF bikes are made in Asia where we don't see the pollution in the air nor worry about safe drinking water, so since we can't see it we think it's all good. You want a real eco-friendly bike than go buy a bamboo bike.
