 The US President preferred a more realistic attitude, because it is hard to believe that it will be possible to fully eliminate pollutant gas emissions in one decade. What is also realistic is the idea that it will be easier to persuade the main polluting agents to take measures by providing incentives to them, rather than by constraint. No matter how cynical this may appear, the US administration is mainly concerned with getting out of the recession and with relaunching the economy, rather than with the greenhouse effect.
