I'm a biologist by trade. Between 1998 and 2008, I set up and ran the BIOCAP Canada Foundation. It was all about biological solutions to climate change. I was very supportive of biofuels at that time because you could drop in fuels and they could result in incremental movement toward a lower carbon energy system. I must say I am very concerned. Now we are talking not about incremental change; we're talking about getting to net zero.
I have very grave concerns about biofuels. We don't have enough residual biomass to make the biofuels, so we need to plant and grow biomass, which means there are going to be impacts on biodiversity, food production and land use. Canada may be able to do it, but the rest of the world can't. We are a country with huge biological resources.
The rest of the world—most of the world—is very clear that they're not looking at biofuels. You can pick Finland and Sweden and a few other countries that maybe are doing it, but....
A real concern is—
