Climate change, recognized as a global crisis, requires innovative solutions to mitigate its impacts. The Intergovernmental Panel on Climate Change (IPCC), established in 1988, has been instrumental in shaping global strategies to combat climate change, providing the scientific foundation for international climate policy. At the core of these strategies is the concept of carbon (C) credits, introduced by the Kyoto Protocol in 1997, which aims to incentivize the reduction of greenhouse gas (GHG) emissions. The quantification of GHG emissions through C credits and tradable permits is vital in promoting sustainable development (SD) and offering financial incentives for emission reduction projects. This chapter includes a section that analyzes the challenges faced by C credits, such as verification, measurement, and financing issues, lack of standardization, market volatility, credibility concerns, regulatory and policy hurdles, lack of transparency, and insufficient domestic demand in certain countries. In response, the next section proposes solutions to enhance the effectiveness of C credits. Strategies like improving transparency and traceability, refining verification processes, fostering community engagement in SD, and introducing financial incentives for emission reductions are suggested. These solutions aim to tackle the identified challenges and improve the overall success of C credit programs. In summary, this chapter serves as an invaluable resource for stakeholders, researchers, policymakers, and practitioners seeking to understand the intricacies of C credits. By examining the challenges and proposing solutions, it outlines a path toward a more sustainable and robust C credit framework, which is essential for addressing the urgent global challenge of carbon emissions.
