Unless we have systemic change (e.g., border adjusted carbon tax), anything we try to do as individuals is going to be penny wise and pound foolish. Most of our carbon footprint comes from industry (including transporting goods). Much of that presumably comes from our trade with China both in terms of their lax pollution laws and then transporting goods across the Pacific. None of that is going to change unless we stop pretending that pollution is free, which is to say we need to pass some carbon pricing scheme so that companies have an incentive to reduce the amount of pollution in the goods they sell us. Greener items will inherently be cheaper, and it will give local manufacturing a competitive advantage (bringing back jobs).
