It is expected that the international meeting will be made an agreement to reduce emissions of greenhouse gases in the atmosphere. They are formed during combustion of fossil fuels: coal, oil and gas. Scientists believe that these emissions are the cause of the greenhouse effect and climate change on earth.

The new document will be designed to replace the Kyoto Protocol - a treaty adopted in Japan in December 1997. Last commits developed countries and countries with economies in transition to reduce or stabilize greenhouse gas emissions in 2008-2012. compared with 1990.

The Kyoto Protocol has been ratified by 181 countries of the world, but the U.S. did not join the agreement. Validity of this document will expire in 2012.

At this time in the discussion of the contract will be attended by leaders of more than 100 nations such as Russia, the United States, Britain, France, Germany, China, India, Japan, etc.

It is to avoid catastrophic phenomena of nature - drought, floods, hurricanes - it is necessary to keep global warming within two degrees. This means that emissions of greenhouse gases to 1990 levels. should be reduced by 2020. by 25-40%, while by 2050. - 50%. However, already among the various countries of the world there are serious differences on this issue.

Because of this, in preliminary talks failed to reach agreement on emissions reductions, as well as providing economic assistance to developing countries to fight climate change.

No State party does not want to sacrifice economic development to achieve environmental goals. In addition, developing countries tend to blame in causing global warming, the industrialized countries, abandoning the serious economic measures to control emissions of greenhouse gases in the atmosphere.
