We have a dedicated team in Environment Canada. There are two of relevance, one that does our national GHG inventory and another that does our modelling and projections into the future. I know they'd be happy to describe their models for you and how they operate.
I can tell you that the inventorying of GHG emissions is done according to the guidelines set by the UN body that all countries follow. Our projections of emissions, where they're coming from and so forth, are based on a generally global model similar to those used in the major G7 countries. We'd be happy to provide additional information on how the models operate.
