If you look at per capita, then Canada is 16 and Australia is 18. If you look at it overall, then China is largest producer: http://en.wikipedia.org/wiki/List_of_countries_by_carbon_dioxide_emissions#List_of_countries_by_2012_emissions_estimates http://en.wikipedia.org/wiki/List_of_countries_by_carbon_dio... If look at it as a percentage of world emissions, it's not even close - China has 26% with the US way back in 2nd with 14%: http://en.wikipedia.org/wiki/List_of_countries_by_carbon_dioxide_emissions#List_of_countries_by_2012_emissions_estimates http://en.wikipedia.org/wiki/List_of_countries_by_carbon_dio... Also, if you look at your home country of Sweden, your overall population is much smaller, you have a much smaller land mass and I would expect your carbon emissions to much lower. Also, your country was smart to start phasing out fossil fuels, and has a ton of very environmentally friendly laws which are doing a lot of positive things for your country. If we in the US actually adapted some of your laws and thinking, we'd probably be a lot further along in reducing our country's impact on the rest of the world.
