This is a hard problem though, there are so many variables. For example, maybe the one that is more eco-friendly to produce is less durable and in the example of flooring which one is more green could depend on how many people a day you have walking on it and what they weigh.

Also economies of scale have an impact too. An expensive eco-friendly product might be produced in smaller numbers causing more waste through the supply chain.

This is all speculation -- but products made a scale are often made with high efficiency.

What surely works is when we ask big corporations to do the right thing. Or if we managed to tax environmental impact.
