For those who despair of the possibility of reforming society wholesale to deal with climate change, a community-level alternative lies in the Carbon Rationing Action Groups (CRAGs) that have been established in the UK and elsewhere. The movement describes itself as such:
We form local groups to support and encourage one another in reducing our carbon footprints towards a sustainable and equitable level. We measure our progress against our carbon allowances. We share knowledge and skills in lower carbon living, raise awareness, and promote practical action in the wider community.
On the one hand, participation in such a group is probably preferable to living a conventional life, from a greenhouse gas emissions standpoint. On the other, this sort of turning inward is poorly suited to dealing with a global problem. We don’t each have our own little atmosphere or our own little climate. The future welfare of the world depends on convincing the mass of people to take action, either actively (by making choices motivated by concern about climate) or by passively responding to new incentives arising from public policies like carbon taxes.
