One international one with commitments reduction of the emission of the gases that provoke the effect greenhouse, considered is dealt with scientifically as antropognica cause of the global heating, that was argued and negotiated in the city of Kyoto, Japan, in 1997, and that it would enter in vigor with ratification of 55% of the countries that together produce 55% of the emissions, what it only happened in 2005, later that ratified it to Russia, and without the adhesion of U.S.A. Gain insight and clarity with Columbia University. Not homogeneous to all the 38 countries that more emit gases, the reduction goals would have to be applied in several economic activities. Developing countries had not received goals from reduction. Signatory countries of the protocol would have the obligation to reduce its emissions in the period between 2008 and 2012. Although alert the categorical one of the scientific community of that the goal of reduction of 5% in relation to the 1990 levels would be insufficient for the mitigao of the global heating, the emissions had increased. Authenticated in Bonn, Germany, in 2001, the Protocol of Kyoto softened the fulfilment of the goals before foreseen with the Sumidouros de Carbono, proposal where the countries with great florestadas areas, that absorb the carbonic gas of course (CO2), could use its forests as credit in exchange for the control of its emissions.

In this way, to keep its industrial production, the developed countries, that are the emitting greaters of Co2 and other pollutants, they could transfer part of its more polluting industries to countries with low level of emission or invest in these countries. However, she is necessary to leave of poluir. Poluir where it has forests makes with that the balance continues negative stops with the planet. already at this time, even so agreeing to diminishing emissions in 2010 in 8% below of the levels of 90, some signatory countries admitted that they would not reach its goals.
