The answer is quite simple. As I indicated, in the short term, we believe that the Kyoto objective is the one we should keep; after all, it a legal obligation. And as for the medium and long term, about a year ago we published, along with the David Suzuki Foundation, a fairly detailed analysis on climate change science and what it tells us as far as the reductions which should be achieved by 2020 and 2050 are concerned. We recommend, for 2020, a 25% reduction compare to 1990 levels, and 2050, a 80% reduction, still compare to 1990 levels. Other governments have already adopted targets in this range.
