Mr. Chair, I think it is important to define metrics around any program area, any policy initiative. The investments the government has made, as I said at the outset, are intended to complement the regulatory regime and are intended to drive behavioural and, particularly, technological change.
I think you can do the math to use a cost per tonne as a metric, and that would provide you with one source of information. You would need to evaluate that over the timeline. You would need to consider what the program goal was. So in terms of performance and performance evaluation, I think it would be important to articulate a series of performance metrics for any particular initiative that is both quantitative and qualitative.
As Ms. Ruta said, we are in the process of developing a horizontal management accountability and reporting framework for the Government of Canada clean air and climate change initiatives. Through that work we are going to develop a logic model, and we will continue to work on performance indicators to help ensure that ministers and others can make good decisions on the most appropriate investment, keeping in mind the specific policy goal.
In the case of the one you mentioned, encouraging Canadians to make more effective use of public transit is an important public policy goal.
