Yes, Mr. Speaker. Yesterday, I answered a similar question from the Bloc Quebecois.
Yes, it is true that it is possible to benefit the environment by reducing greenhouse gases and, at the same time, to have economic growth. I am very pleased that the member has noted that it is possible to have both.
But there are also other factors which must be taken into consideration before a railway company can change its system of locomotive engines. I expect a decision which takes into account all the important factors.
