The world is on on a crash diet. Not to count carbs, but carbon. We've joined the Paris Agreement, which aims to limit global warming to 1.5°C. But like so many diets, this one might not stick.

Australians are the great diet cheats. We've got one of the biggest footprints but we've pledged a tiny cut. Bushfires, storms, drought & flood. If everyone follows our lead, the world will be in climate chaos.

I cut back our household carbon footprint by 77%. I took simple steps anyone can take. I ran one-week experiments and did the math.
