When we were doing our audit we found a variety of sources of information that date back to the 1990s. When the government started the national process for consulting on how to deal with climate change, information came forward from industry and other participants.
Natural Resources Canada has also contributed projections--what they call emissions outlook--and I believe in 2002 they came out with their last report. Then there's the National Energy Board itself, which does market assessments on a regular basis as part of their mandate. In this report we chose to cite the National Energy Board because it was the most recent information available to us.
