"97% is from nature and the remaining 3% is man made."


In addition, this is for Denben:

Australia's global co2 emissions are 1.35%

So, if we take 3% of 1.35 - Australia can only reduce global co2 emissions by a maximum of 0.04% IF we all stop breathing, use no power, drive no cars, etc. So, what's the point of taxing the hell out of this country?
