As climate change becomes increasingly severe, companies' carbon emissions are becoming a focal point of concern for stakeholders. Despite the accumulation of numerous researches in Taiwan that discuss the correlation between emissions and stock prices, numerous domestic studies consistently indicate that due to a later start in environmental awareness and regulations, the number of listed companies that have completed carbon inventory is limited, resulting in limitations in these researches. This study takes the period from 2002 to 2022 as the sample interval. First, carbon-related variables are ranked and long-short portfolios are constructed in the U.S. stock market to verify the existence of carbon premiums. Subsequently, these portfolios are used as proxies to verify Taiwan's carbon premiums. Regression analysis is conducted on Taiwan's listed companies. Rolling beta for each company over the past 36 months are extracted and used as ranking variables to establish long-short portfolios. This further explores whether there are carbon premiums in Taiwan. The verification results in the U.S. show that carbon premiums are insignificant due to the sample interval covering the period of COVID-19, causing fluctuations in the carbon-price relationship. As for Taiwan, similar insignificance is observed. In addition to the pandemic, two reasons can be summarized: First, the Taiwan market has not received sufficient investment resources from major investment institutions, making it difficult for investors to obtain ESG-related information. Second, regulatory standards for carbon disclosure are lenient, which is not enough to raise concerns about emissions.參考文獻 Aupperle, K. E., Carroll, A. B., and Hatfield, J. D. (1985).
