Brazilian President Luis Inacio Lula da Silva dropped the diplomatic niceties during a speech in Rio de Janeiro. He demanded that developed countries do more on reducing GHG emissions, accused them of having a double standard on the issue and warned them not to lecture him on the Amazon rain forest.

Some excerpts from the BBC story:

He said they were skilful at drafting agreements and protocols, like the Kyoto treaty, to appear as if they were doing something to reverse dangerous gas emissions.

In practice, however, he said the results proved otherwise.

'World leader'

President Lula was most adamant on the issue of deforestation.

Developed countries, he said, had nothing to teach Brazil on the subject, adding that his country had reduced the deforestation of the Amazon rainforest by more than 50% in the last three years.

Brazil says it has reduced Amazon deforestation by 50%
This was something which should serve as a lesson to developed countries, which in his words, had already deforested everything under their control.

On the subject of alternative fuels, President Lula described Brazil as a world leader.

And indeed the South American country is the world's largest producer of ethanol made from sugar cane and it has the world's largest fleet of cars that run on alternative fuels.
