The city we like to point to is Portland, Oregon. It appears that they have successfully managed energy efficiency, city planning, and land use, while engineering an absolute reduction of carbon emissions over the last ten years or so. That's one example. My own home city of Berkeley, California, has done fairly well too in reducing its total carbon emissions. Is there a unified plan? I would say Portland has done a better job than most in looking at the whole picture. Portland always rises to the top.
