The biggest obstacle to reducing greenhouse gases isn't a political party. It's commuting.
Look at the top US employers worlwide (or the largest sectors of employment [0]), there is no way UPS, walmart, fedex, starbucks, &c. can work with remote employees. [1]

If you had said there was no way those employers can work with all their employees being remote, that would be true.
However, all office work could potentially be remote with little or no technical advancement from where we are now. When I look around the city I'm in (Boston) I see a lot of office buildings. I think the potential reduction in commuting is huge.
You mention your feeling that the vast majority of jobs are done more efficiently in person. Do you still feel the same way when you factor in the unproductive hours spent behind a steering wheel daily?
