Regarding evolution f CO2 emissions per 1000 dollars of GDP, which measures, for the same country, the "environmental efficiency" with which it is produced over time. In the last period, Tonga, has emitted 0.23 kilos for every $ 1,000 of GDP, more than in 2013.
In the table we can see the evolution of CO2 emissions, which have grown since 2004, as have per capita emissions and as well as CO2 emissions per $ 1,000 of GDP.
