Unfortunately the way that these things are done in the accord is far too vague to work. It is hard to say what the accord’s targets imply in terms of actual emissions, because issues such as LULUCF accounting, international trading, carryover of Kyoto AAUs, and definitions of ‘business as usual’ are completely unspecified. Furthermore, the conditions that countries have specified for their conditional targets are completely vague, and it is impossible to be able to tell with much certainty from the accord schedule whether any of these conditions have been met.
