The government has committed itself to raising the share of revenues from green taxes over this Parliament. On its own definition of what constitutes a ‘green tax’, the pledge is on course to be met with ease. Alternative definitions of green taxes based on international convention, however, suggest that the pledge will be missed. We argue that such pledges are not a good guide to a government’s environmental credentials, and green tax policy should be justified by environmental issues rather than an arbitrary revenue target.
