Abstract
The scientific evidence is reviewed for claims that a global transition to “green” fuels and technologies by global treaty obligations is needed. The likely equity implications of these efforts are discussed, and it is argued that this evidence remains shaky. Measures based on this contested knowledge cannot be defended on grounds of either environmental effectiveness or equity. Rather, they rely on commercial expectations and promises of secondary benefits usually requiring state intervention. Poorer groups and nations are unlikely to benefit from proposals to redirect energy policies to “combat global warming.” The advocated decarbonization of global energy supplies is more likely to increase political instability than prevent climatic change. To support this argument, three areas of knowledge are consulted: controversies about the causation and likely impacts of global warming, advocated technical and fiscal solutions, and the interests of technical, commercial, and political elites.
