BRASILIA - The Presidents or representatives of the eight Amazonian nations and France will debate a common stance on Thursday for the Copenhagen Conference on Climate Change in Manaus, capital of Brazilian Manaus state.

Lula leads an international stance to accomplish a serious commitment of the developed and developing nations to considerably reduce the emissions of greenhouse gases, which are responsible for the global warming.

The Brazilian government expressed its commitment to reduce between 36.1 and 38.9 percent of the emissions of greenhouse effect gases and to accomplish that it would reduce 80 percent of deforestation in the Amazonia. For that reason, it would stop releasing 580 annual tons of carbonic gas to the atmosphere.

Brazilian presidential spokesman Marcelo Baumbach told press Lula "expects the Manaus meeting to be a strong message, with a clear expression of the agreements and a basic consensus on the negotiations of Copenhagen, stressing on the issues of reducing emissions, adaptation, financing and technology.

The Amazonia is the largest terrestrial ecosystem and has a key role in the climate sustainability of the planet.

Baumbach said the struggle against climate change demands a global effort to reduce gas emissions that respects the different responsibilities and conditions of the developed and developing countries.
