Given the increasing climate challenges, this report updates Thailand's BCG model for current circumstances. We call it BCG+. The report uses advanced modeling and other cutting-edge analytics to take a whole-of-the-economy perspective so that BCG+ is assessed within the context of broader economic development. Beyond environmental concerns, Thailand's economic risks, tied to global trends and its reliance on tourism, necessitate a revised development model. The BCG+ economy could mitigate these exposures by reducing reliance on global commodity prices and enhancing economic resilience. By integrating measures on climate resilience, sustainable resource management, and inclusivity in its development strategy, Thailand can work towards achieving its vision of a BCG economy.
