In 2021, CO2 emissions in Iceland have grown 0.198 megatons, 7.31% compared to 2020.
CO2 emissions in 2021 were 2.908 megatons, making Iceland is the 42th conutry in the ranking of countries for CO2 emissions, made up of 184 countries, in which the countries are ranked from least to most pollutant.
In addition to its total emissions of CO2 into the atmospher, which logically depend, among other variables, on the country's population, it is convenient to analyze the behavior of its emissions per inhabitant. In the table we see that per capita CO2 emissions in Iceland, have increased in 2021, in which they have been 8.4 tons per inhabitant.
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, Iceland, has emitted 0.15 kilos for every $ 1,000 of GDP, more than in 2020.
In the table we can see the evolution of CO2 emissions, which have decreased since 2011, as have per capita emissions and as well as CO2 emissions per $ 1,000 of GDP.Total carbon dioxide emissions have also decreased compared to 2016, although per capita emissions have increased in this period.
