I don't advocate complacency or fatalism, instead I've come to hold the opinion that rapidly shifting to low/zero carbon technology is our best shot. Just look at how quickly natural gas felled king coal - a matter of years - once it became significantly cheaper. (We can't stop at natural gas, but it does produce half the CO2 as coal)
A key part of this viewpoint is that strong demand in the market can actually be an accelerator.
Turning back to austerity - even if a 50% drop in demand could save us, it's just never going to happen. Even the global COVID lockdowns made less than a 10% cut in energy consumption. You'd be stunningly successful if you cut even 1% through austerity campaign.
