When it became evident that climate change may be occurring there was
the beginning of the movement that was responsible for the Kyoto meeting
in December of 1997: a section of the United Nations was formed the
United Nations Framework Convention on Climate Change (you might see
UNFCCC in some of the linked text). The first meeting was the Earth
Summit in Rio de Janeiro, subsequent meeting set up the meeting
where a reduction strategy for climate change was presented. This meeting
was held in Kyoto, Japan and the vice President (Al Gore) signed for
the US.
Reduction of six greenhouse gases by some countries, to varied levels
below their emissions of greenhouse gases in 1990.
- carbon dioxide (CO2)
- methane (CH4)
- nitrous oxide (N2O)
- hydrofluorocarbons (HFCs)
- perfluorocarbons (PFCs)
- sulphur hexafluoride (SF6)
The treaty to become legally binding when
it is ratified by 55 Countries (they use the term States) but that
must
include Developed Nations responsible for 55% of the carbon
dioxide
emissions from the Developed Nations group in 1990. The treaty could
not be ratified unless nearly all of the G8 countries ratified it.
The US being the largest contributor to global anthropologic
CO2 emissions has a key role in the protocol
and can kill it with the
assistance of just a couple of other countries (via not ratification).
When Russia ratified the treaty it entered into force a few weeks later (Feb,
2005). You can
read more from the wikipedia page on the subject.
Just to confuse everyone (and so as not to embarrass developing countries)
they use the terms Annex 1 parties (mostly developed nations) and Annex
2 Parties (mostly the developing nations).
An emission trading methodology was adopted to reduce the cost of compliance
(but details on how this will work are not yet in place). A major victory
for the US as we utilizes this approach for SO2
and NOx emissions via the Clean Air Act of
1990 and its amendments.
Developing countries have a right to develop and so will
not have to reduce or curtail their emissions of greenhouse gases at
all.
Changing land use issues and natural carbon sinks (such as planting
a forest) also impact the reduction levels assigned (and agreed to).
Sharing of technology (sounds a tad socialist to me).
There is a great deal of uncertainty in how everything will work out.
The European Union is allowed to act as a bubble and redistribute
the reductions to meet the overall reduction level required.
