Motor transport, greenhouse gases and economic instruments
Motorised transport is the generator of several forms of negative externality including the uncompensated emissions of greenhouse (global warming) gases. This paper looks at some of the underlying economic issues pertaining to policy-making designed to limit the extent of these externalities. It sets out the basic nature of the problem and outlines our knowledge of the link between the physical sciences involved and the relevant economic theory. It focuses, in particular, on the strict question of quasi-internalisation in the context of a global externality.
