The purpose of this article is to examine empirically the impact of environmental certification on firm financial performance (FP). The main question is whether there is a "green premium" for certified firms, and, if so, for what kind of certification. We analyze the short-run and the long-run stock price performance using an event-study methodology on a sample of Canadian and U.S. firms. The results of short-run event abnormal returns indicate that forest certification does not have any significant impact on firm FP regardless of the certification system carried out by firms. Unlike the short-run results, the long-run post-event abnormal returns suggest that forest certification has, on average, a negative impact on firm FP. However, the impact of forest certification on firm FP depends on who grants the certification, since only industry-led certification (Sustainable Forestry Initiative, Canadian Standards Association and ISO14001) are penalized by financial markets, whereas non-governmental organizations—led Forest Stewardship Council certification is not
