In this study, it is discussed how many countries are still relying on carbon-heavy energy sources despite talking about protecting the environment. The Kyoto Protocol and UNFCCC offer ways for developed nations to meet emission goals by investing in cleaner projects in developing countries. The research suggests that to combat climate change effectively, we need to consider the complex nature of the issue. Cooperation among nations, especially in the developing world, is crucial for creating sustainable economies. The study uses the Caribbean as an example to show how regions can transition to cleaner economies while boosting investment opportunities. Looking ahead to the end of the Kyoto Protocol in 2012, it is essential for developing nations to build sustainable economies now to support future growth.
