Thank you, Mr. Chair. Thank you to the witnesses.
My first question is for Mr. Layzell.
The end goal of this entire process is to mitigate the effects of climate change. Everything we're doing is leading to that end, but sometimes I think we get too focused on the goal of achieving net-zero carbon emissions while possibly ignoring the consequences of emissions of other greenhouse gases of varying levels.
I've read that in some places water vapour is a significant greenhouse gas. Water vapour is a byproduct of the combustion of hydrogen, and hydrogen, even in its gaseous form, if it were to escape also does have some impact on the climate as well. I was wondering, what's the evidence around that? Is there an impact?
