I've been told that this amendment is problematic, and that leads me to make the following ruling that it's not admissible. I will tell everyone why.
Bill C-12 requires that national targets for the reduction of greenhouse gas emissions in Canada be set with the objective of attaining net-zero emissions by 2050. The bill establishes that “net-zero emissions” means that anthropogenic emissions of greenhouse gases into the atmosphere are balanced by anthropogenic removals of greenhouse gases from the atmosphere over a specified period.
Amendment PV-4 seeks to achieve net-zero emissions through an absolute greenhouse gas emissions reduction of at least 90% below 2005 levels, which is not foreseen in the bill.
The House of Commons Procedure and Practice book, third edition, states on page 770:
An amendment to a bill that was referred to a committee after second reading is out of order if it is beyond the scope and principle of the bill.
In my opinion, PV-4 introduces a new concept that is beyond the scope of the bill. Therefore, I must rule the amendment inadmissible.
