This study examines how the greenness of the firm affects the short- and long-term performance of IPOs. To measure the greenness of the firm, we develop the Greenness Index based on the emissions produced. We find that the greenness of the firms operating in services and financial sectors is higher than in other sectors. To examine the short- and long-run performance of IPOs, we classify our sample into high and low green firms. In the short-run, high green firms obtain a lower return than low green firms. However, high green firms perform better than low green firms in the long-run. This study also determines the factors that cause short- and long-run performance, and the results suggest that the firm’s greenness negatively influences initial returns and underperformance of IPOs. Finally, we develop a theoretical model in terms of the portfolio's allocation and assert that investors participate in high-green firms to optimize their portfolio.
