Harmonized emissions/carbon/energy tax
Commits participating countries to impose a tax at a common rate on the same
sources. Each country can retain the tax revenue it collects.
A harmonized tax would not necessarily require countries to impose a tax at
the same rate, but imposing different rates across countries would not be cost-effective.
See also emissions tax.
HFCs
See hydrofluorocarbons.
Hydrofluorocarbons (HFCs)
Among the six greenhouse gases to be curbed under the Kyoto
Protocol. They are produced commercially as a substitute for chlorofluorocarbons.
HFCs largely are used in refrigeration and semiconductor manufacturing. Their
Global Warming Potentials range from 1300 to 11,700.
