Nitrogen Oxide Protocol
The Nitrogen Oxide Protocol to the 1979 Convention on Long-Range Transboundary Air Pollution Concerning the Control of Emissions of Nitrogen Oxides or Their Transboundary Fluxes, opened for signature on 31 October 1988 and entered into force on 14 February 1991, was to provide for the control or reduction of nitrogen oxides and their transboundary fluxes.
Kyoto Protocol
The Kyoto Protocol to the United Nations Framework Convention on Climate Change is an amendment to the international treaty on climate change, assigning mandatory emission limitations for the reduction of greenhouse gas emissions to the signatory nations.
The objective of the protocol is the "stabilization of greenhouse
gas concentrations in the atmosphere at a level that would prevent
dangerous anthropogenic interference with the climate system."
As of December 2006, a total of 169 countries and other governmental
entities have ratified the agreement (representing over 61.6%
of emissions from Annex I countries). Notable exceptions include
the United States and Australia. Other countries, like India and
China, which have ratified the protocol, are not required to reduce
carbon emissions under the present agreement.
Convention on Long-Range Transboundary Air Pollution
The Convention on Long-Range Transboundary Air Pollution, often abbreviated as Air Pollution or CLRTAP, is intended to protect the human environment against air pollution and to gradually reduce and prevent air pollution, including long-range transboundary air pollution.
