The ruling described in this Washington Post article is based on the idea that the climate is a natural commons which needs to be protected for public use – an approach that ties in with the arguments made in Feasta’s book Sharing for Survival. The lawsuit which brought about this ruling was part of a campaign by the Oregon-based non-profit Our Children’s Trust. It’s carrying out similar lawsuits in a number of other US states. Perhaps a similar approach could be effective in other countries?
