Environmental

This includes natural resources consumption tax, greenhouse gas tax (i.e. carbon tax), "sulfuric tax", and others. The stated purpose is to reduce the environmental impact by repricing. Economists describe environmental impacts as negative externalities. As early as 1920, Arthur Pigou suggested a tax to deal with externalities (see also the section on Increased economic welfare below). The proper implementation of environmental taxes has been the subject of a long-lasting debate.
