Sure. With respect to the reference in Liberal amendment 4, new paragraph (c) does reflect the strong commitment to the Kyoto Protocol, which would imply a commitment to the 1990 target.
Of course future governments are going to be dealing with the future and subsequent successor arrangements after 2012. It will not be the Kyoto Protocol; it will be something else.
I think this attempts to take the environment minister at his word, that Canada wants to be a leader, that Canada wants to be part of the international system. Canada is not denying the science of the UNFCCC and neither is the parliamentary secretary. It gives a formulation that is flexible enough to take into account the changes we can't anticipate, but lays down some principles of equity that will remind us of what, as a responsible, developed, leading country, Canada must do.
