The graph below illustrates the amount of CO2 released from five areas between 2000 and 2020, with projections extending to 2040. Overall, it is evident that CO2 emissions in Region 1 decreased, while Regions 3 and 4 experienced upward trends. In contrast, Regions 2 and 5 showed steady fluctuations. Furthermore, all of these trends are expected to continue in the future. Region 1 recorded the highest amount of CO2 emitted and is predicted to maintain its leading position moving forward.
In 2000, CO2 emissions in Region 1 stood at 8 million tonnes, increasing to approximately 9.2 million tonnes by 2010. Following this peak, emissions fell to nearly 7.5 million tonnes in 2020, and this downward trend is projected to continue until 2040, when emissions are expected to reach 7 million tonnes.
In Region 4, CO2 emissions were 4 million tonnes in 2000, dropping to 3 million tonnes before rising to nearly 5 million tonnes by 2020. It is anticipated that emissions will increase to 6 million tonnes by the end of the period. Meanwhile, in Region 3, emissions started at nearly 3 million tonnes in 2000 and have shown a gradual increase, a trend that is also expected to persist in the future.
Region 2 recorded CO2 emissions of 6 million tonnes in 2000, with figures oscillating around this amount without significant change, and projections indicate this trend will continue through 2040. Similarly, Region 5 reported only 1 million tonnes of CO2 emissions in 2000, experiencing fluctuations, but it is expected to increase slightly to 1.3 million tonnes by 2040.
