1. Introduction
Policy strategy for controlling risky excess atmospheric greenhouse gas (Gowdy, 2008, Sect. 4; McKibben, 2007, Ch. 1, pp. 19-20; Solomon et al., 2009; Tickell, 2008, Ch. 6, pp. 205-208) mostly derives from the notion that carbon dioxide emissions should be charged for, in order to prevent future emissions; similar to treatment for environmental pollutants (Giddens, 2009, Ch. 6, pp. 149-155; Gore, 2009, Ch. 15 “The True Cost of Carbon”; Pigou, 1932; Tickell, 2008, Ch.4, Box 4.1, pp. 112-116). Underscoring this idea is the evidence that fines, taxes and fees modify behaviour, reigning in the marginal social cost of “externalities” through financial disincentive (Baumol, 1972; Sandmo, 2009; Tol, 2008). However this approach may not enable the high-value, long-term investment required for decarbonisation, which needs adjustments to the economy at scale (CAT, 2010; Hepburn and Stern, 2008, pp. 39-40, Sect. (ii) “The Consequences of Non-marginality”; MacKay, 2008, Ch. 19; Tickell, 2008, Ch. 2, pp. 40-41).
