What you're proposing is of course good and mostly matches my lifestyle, but it's not a solution. If everybody did everything you say we could probably cut down our CO2 emissions by 70% or so. What do we do about the remaining 30%, except wait until the no-child policy eradicates humanity? We still need to get rid of all fossil fuels. Luckily we already have the technology to do so, and by building that out we can keep most of our lifestyle with far less emissions.
