Environmental pricing reform

Environmental pricing reform (EPR) or Ecological fiscal reform (EFR) is a fiscal policy of adjusting market prices to account for environmental costs and benefits; this is accomplished by the utilization of any forms of taxation or subsidy to incentivize or disincentivize practices with environmental impacts. An externality (a type of market failure) exists where a market price omits environmental costs and/or benefits.
