This means ....
USA eliminates CO2 - more than double of Japan - in terms of GDP. It is not a subtle difference, but a big difference. Other countries are much worse. Chinese eliminates CO2 - some 11 times more than Japan, and Russia is some 18 times more than Japan - Terrible.
Those low-efficient countries should stop using old production facilities and use Made-in-Japan efficient machineries.
Plus, Those low-efficient countries should develop public transportation and live in smaller house. In addition, they should eat rice, not meat.
