I thank the council members for attending and giving us the benefit of their expertise. Obviously, they have done an incredible amount of work in getting the report to us. That has to be commended. On a very high-level basis, I have questions about some of the methodology the council has used. I understand that, between this report and the council's most recent budget, the council has moved from using the Paris test to a temperature neutrality test. I am interested to hear the witnesses' thoughts about why it has changed from one to the other. Perhaps the council members could address this first.
