I made it up.

I can't remember honestly, that 3% number was honestly a guesstimate because I know it was some fraction not a whole number.

Some documentary on YouTube a couple years ago, or it may have been an episode of media watch. That vaguely feels like where I remember it from.

I'm happy to be corrected.

But I know for sure our per capita CO2 emissions are higher than most other countries including China.

For how small our population is we are one of the worst polluters.
