" Going “green” helps company stock. According to a joint UC Davis and UC Berkeley study released on January 29, companies that disclose “green” efforts see a spike in stock prices. The report, written by Paul Griffin of UCD and Yuan Sun of UCB, studied 172 companies that made voluntary disclosures of carbon-emission information between 2000 and 2010. In the five days surrounding these announcements, companies saw an average of nearly half a percent increase in stock prices. For small companies, “green” announcements had an even greater positive effect on stock prices. "
