5. Ethiopia
Emissions – 0.10
We’re seeing that the African continent is the greenest of all, although that’s probably in part due to the lower industrialization found here and vast lands. In Ethiopia, for instance, 2015 saw a level of CO2 emissions of 0.10 metric tons per capita. The climb here was larger than in other nations before it, as in 2010 the levels were of only 0.07 metric tons of CO2 per capita.
