Thank you, Madam Chair. I'd like to respond to the member's question.
I don't have the exact data with me. However, I do know that with the greenhouse gas emissions and the energy to produce the glass, it is far less efficient—in particular, the weight of it and transporting it—thus the choice of plastic and aluminum, which are both highly recyclable and both fairly equivalent in terms of the use of energy. I could look at what may be available to get more exact data for you.
