CO2 Emissions per Capita

CO2 Emissions per Capita

Abstract

This work analyzes CO2 emissions per capita (CpC) in the period 1990-2020. The dataset includes 212 countries, 99.8% of the global CO2 emissions. The world average CpC was 4.3366 tCO2/y,cap in 2020, 4.1% above the 1990 level. CO2 emissions above the world average CpC in period 1990-2020 by 81 countries were 39% of the global CO2 emissions in this period, which increased the Global Warming by 0.249°C. The average CpC in 2020 of the 81 countries above the world average CpC was 8.62 tCO2/y,cap in 2020, 5.6 time more than the countries below the world average. 100 countries reduced CO2 emissions per capita between 1990 and 2020 by 21% in average, comparing to the world average increase of 53%. The reduction of the CpC by the 100 countries decreased the Global Warming by 0.21°C. OECD (1990) countries and Annex I (Kyoto) countries, 41 countries having 22% of the world population, caused 49% of the Global Warming + +0.316°C between 1990 and 2020. This group of countries reduced CO2 emissions by 21% between 1990 and 2020, however the group’s average CpC was still 206% of the world average in 2020, 8.94 tCO2/y,cap, comparing to 3.38 tCO2/y,cap of the rest of the world. 10 countries above the world average of CO2 emissions per capita (2020) with the highest change in cumulative CO2 emissions between 1990 and 2020, caused 63% of the Global Warming, +0.407°C, in the period. The average CpC of these 10 countries was 195% of the world average, 8.71 tCO2/y,cap in 2020, comparing to 2.36 tCO2/y,cap of the rest of the world. CO2 emission of 5 countries from this group is above the group’s average CpC of 8.71 tCO2/y,cap, 7% of the global emissions of the world.
