*How is Australia trying to sell a major gas expansion? By badging it "sustainable".*

The plan is to start extracting gas from large reserves, and bet that carbon capture will be improved fast to cancel that out. If the bet succeeds, this expansion may be carbon-neutral, unless something else goes wrong.

If the bet fails, what will they do? Shut down the gas extraction? I don't think so. They will say, "Too bad, but you can't win 'em all. Enjoy your increased greenhouse emissions!"

The only sense in which this is "sustainable" is that they could hope to sustain the extraction from these new gas fields until civilization collapses from climate breakdown.

This is a plan to bet young people's lives. The owners of those companies should bet their own lives instead.
