My memory is not much better than yours; I'm getting advanced in years. It has been a couple of decades, so yes, you are right, our work on this stuff precedes Canada's commitment to phase out fossil fuel subsidies.
At the foundation of that work is what you imply, the basic premise that subsidizing fossil fuel consumption in a time of climate emergency is akin to putting your foot on the accelerator as you head toward a cliff, when what you should be doing is braking and changing course. We don't need more production and consumption of fossil fuels—that's what fossil fuel subsidies encourage—we need less. We need those same public dollars to go towards finding the very real solutions, the replacements for fossil fuels, which exist. Green hydrogen is a replacement for fossil fuels in fertilizer production and in steel production.
We have the technologies to replace fossil fuels in industrial production, in transport, in residential heating. They exist; it's not a fairy tale.
