The line graph below illustrates the amount of CO2 emission (measured in million tonnes) released from different parts of the world between 2000 and 2020, with projections extending to 2040.
Overall, although region 1 is predicted to experience a downward trend over time, it remains the highest emitter of CO2 throughout the period. It is also clear that while regions 3 and 4 will see a marked rise in emissions, regions 2 and 5 will display fluctuating patterns.
In terms of the disposed of CO2 emissions in regions 2 and 5, emissions from region 2 remained relatively stable, at around 6 over the years, with projections suggesting a return to 6 by 2040. Region 5 followed a similar but more volatile pattern, ranging from 1 to nearly 2. The quantity of CO2 emission in this region ranks the lowest in most years.
Turning to the remaining categories, starting at 8 in the first year, the amount of CO2 emission in region 1 witnessed a sharp increase, reaching a peak of over 9 before declining to above 6 in 2020 and being projected to fall further to exactly 6 by 2040. In contrast, despite decreasing dramatically from 4 to 3, region 3’s emissions rose drastically to nearly 5 in 2020 and are forecasted to reach parity with region 2’s. Meanwhile, there is a significant increase in the amount of CO2 emissions, predicted to stand at exactly 5 in the final year.
