"… environmental sustainability will not be served by introducing or extending market instruments and norms to various areas of society, but quite the reverse. It would be better served by expanding and supporting the public sphere – both procedurally and substantively."
Another must-read article from the OpenDemocracy web site explaining why sustainability cannot be attained by putting a market value on natural capital and the economic "commons".
“market instruments and norms need to be removed from areas for which they are simply not appropriate. In essence, the social project for sustainability is part of that, as Karl Polanyi ↑ recognised, to arrest all manner of social ills produced by unfettered markets. It is part of the social project of (re)subjecting markets, in particular, key resource use, to social and democratic control. Subjecting markets and key resource use to genuine democratic control means that markets may be made to serve people and planet rather than the other way around.”
