South Africa: CO2 Country Profile
This interactive chart shows how much carbon dioxide (CO 2) is produced in a given year.. A few points to keep in mind when considering this data: These figures are based on 'production' or 'territorial' emissions (i.e. emissions from the burning of fossil fuels, or cement production within a country's borders).
