Methodology
We compiled a list of the 25 countries that produce the most carbon dioxide emissions by evaluating CO2 emissions per country. Our ranking was based on three primary metrics: CO2 emissions per capita (metric tons), total carbon emissions, and CO2 emissions per GDP.
We collected data on the relevant metrics from different websites. We got CO2 emissions (metric tons per capita) from The World Bank, total carbon emissions from World Economics, and CO2 emission per GDP from Climate Watch.
CO2 emissions per capita is a metric that measures the amount of carbon dioxide (CO2) that a country or region emits into the atmosphere per person, expressed in metric tons. It provides an indication of the average environmental impact of each individual in terms of carbon emissions.
Total carbon emissions are the cumulative amount of carbon dioxide (CO2) and other carbon compounds released into the atmosphere by human activities, such as burning fossil fuels, deforestation, and industrial processes. This metric is a key measure of a region or country’s overall impact on climate change.
CO2 emissions per GDP, also known as CO2 emission intensity, is a metric that measures the environmental efficiency of an economy. It is calculated by dividing the total CO2 emissions of a country by its GDP. A lower CO2 emissions per GDP indicates a more environmentally efficient economy, while a higher value suggests a greater level of environmental impact for each unit of economic output.
We first scored each country on each index from 1 to 25, with 1 indicating the country with the most emissions and 25 indicating the country with the least emissions. We then assigned weights of 0.5 to CO2 emissions per capita, 0.3 to total carbon emissions, and 0.2 to CO2 emission per GDP. Finally, we calculated a composite weighted average of these scores to determine the countries that produce the most carbon dioxide emissions.
After the final evaluation of the composite results, the countries were ranked from 1 to 25, with 1 indicating the country with the most carbon dioxide emissions and 25 indicating the country with the least emissions.
Below is our complete list of 25 countries that produce the most carbon dioxide emissions.
