The line chart illustrates the amount of CO2 emissions in various areas over the course of two decades, starting from 2000, along with projections extending to 2040.
Overall, it is noticeable that the CO2 emissions was by far the most popular of the five types of region of the 20-year period and will continue to dominate in the next 20 years. In contrast, regions 3 and 4 will see a marked rise in emissions, while regions 2 and 5 will display fluctuating patterns, with Region 5 consistently emitting the least CO2.
Region 1 was the highest emitter over 4 decades, beginning the period with 8 millions of metric tonnes (Mt) of CO2 emission, reaching a peak of over 9 Mt after a decade before dropping significantly to 7,5 Mt in 2020, which are expected to continue to decline by about 0.5 Mt compared to 2000 and took at 7 Mt in 2040
Regions 2 and 5 have seen a similar trend, whereas region 2 is the one with higher emissions, with 6 Mt in the initial period and is expected to remain unchanged in 2040. In contrast, region 5 is expected to consistently record the lowest emissions, accounting for negligibly 1,5 Mt, 9 times as lower as that of region 2 by 2040.
Region 3 initially fell from 4 million Mt to 3 million Mt in 2005, then climbed to 5 million Mt by 2015 before leveling off. After keeping emissions at 4 Mt for 15 years, Region 3’s emissions are anticipated to climb once more and match Region 2’s by 2040. Additionally, emissions in region 4 have seen a steady increase and are projected to continue to increase, from 2,8 Mt in 2000 to 5 My in 2040
