My question is to the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. I refer the minister to evidence given by Treasury officials at the shotgun inquiry into the carbon tax legislation that beyond 2020 they modelled:

… a scheme where countries make the same emission reductions as each other relative to their 'business as usual' path.

So, the analysis is that OPEC countries would reduce their emissions relative to their business as usual path by the same amount as Australia. Will the minister inform the Senate precisely what level of international action is assumed in the Treasury modelling for OPEC countries, and all other countries, of the carbon tax beyond 2020?
