The study looks at ways to reduce carbon emissions in Southeast Asia. It explores different plans to cut energy use and carbon output. The researchers use two models to see the effects of these plans. One model gives a detailed look at energy technology, while the other shows how these changes affect the economy. By combining these models, they find that Southeast Asia countries can improve energy efficiency and reduce carbon emissions by working together on de-carbonization policies. This research shows that with the right strategies, Southeast Asia can make progress towards a cleaner, more sustainable future.
