It's not enough though. Not on its own.
There has to be a technological breakthrough to greatly reduce the footprint per-capita.
Honestly though, I suspect we need a larger technological advancement than that anyhow -
because I'm convinced we're over the tipping point, with methane releases having begun.
I am very much inclined to agree with you.
But we can talk all we like about how we need to reduce the global human population by something like 90%. And it won't change a thing. We can talk all we like about reducing the carbon footprint of each person currently on the planet, but even if we reduce each person's carbon footprint by 50% it won't be enough if the population continues to grow. And very few countries are serious enough about tackling climate change to reduce carbon footprints by any appreciable margin anyway - and the big carbon emitters seem to be doing all they can to make more CO2.
So what can we do? Green technology and taking the steps that have been repeatedly shown to be effective at reducing fertility rates (and eventually population once the lag caused by an ageing population is taken into account) - and hope that the world's ability to support us (and other life forms) before that can have any effect.
