Total amount is 3100 gigatonnes, world emissions over 3. 4 gigatonnes, 1 gigatonne = 1 billion metric tons, 4. 8 tonnes per person per year. Note some stats are given in tonnes of carbon. 25% goes to oceans, 30% goes to land ecosystems and 50% into atmosphere. Countries by co2: china is 25% which is 8. 5 gigatonnes per year, us 16% which is 5. 4 gigatonnes per year, eu is 10%, india 6%, russia is 5%, japan 3% and rest of the countries is less than 2%. Emission numbers: world per capita emissions is 4. 8 tonnes per year, us is 17. 3 tonnes per year. Highest per capita are oil producing states like qatar and kuwait. Us is 12th and is 3. 3 times world average and.
