This seems a bit myopic..using the type of non-systems thinking that has gotten us into the eco/social quagmires we face.

“We can't solve problems by using the same kind of thinking we used when we created them.” - Albert Einstein

We need to push for and implement systems-based solutions that create new models, not limited changes that keep our current systems in place. Water, waste, deforestation, depletion of non-renewables, using renewables faster than they can be replaces, pollution and other environmental issues are all significant.

A product could be zero carbon through cheap offsets as well. Only by using systems-based solutions do we successfully and permanently address climate change and other issues, as they are interrelated.
