The Green

Ecotax = "short for ecological taxation [and] can refer to a fiscal policy that introduces taxes intended to promote ecologically sustainable activities via economic incentives. Such a policy can complement or avert the need for regulatory approaches. Often, such a policy intends to maintain overall tax revenue by proportionately reducing other taxes, e.g., on human labor and renewable resources, in which case it is known as the green tax shift towards ecological taxation.

"An ecotax has been enacted in Germany by means of three laws in 1998, 1999 and 2002. The first introduced a tax on electricity and petroleum, at variable rates based on environmental considerations; renewable sources of electricity are not taxed. The second adjusted the taxes to favor efficient conventional power plants. The third increased the tax on petroleum. At the same time, income taxes were reduced proportionally so that the total tax burden remained constant."
