I actually agree(disagree?) even more strongly. The entire concept of "personal carbon footprint" is a distraction. The behavior of individuals is both random and highly variable (e.g., cyclists vs coal-rollers), and even in the practically impossible situation every individual moves in the same good direction, is still dwarfed by the institutional and industrial scale It is not only "also" reform political and economic systems, it actually the only path to a real solution. (Of course, do what you can to incidentally optimize footprint when it's an A/B choice. But if it's two hours of extra work to avoid some personal carbon output/use, it's better to spend that two hours on some political or economic action)
