"Companies that disclose greenhouse gas emissions see a small rise in stock price following disclosure, compared to similar companies that keep mum, researchers say."
"Full disclosure about greenhouse gas emissions and carbon-reduction strategies can lift a company's economic value, a new study has found.
Investors are saying they would prefer to invest in an environmentally responsible firm.
Business scholars tracking stock prices of 172 firms in the days after those companies voluntarily released carbon emission information found that prices jumped an average of just under half a percent over five days.
Smaller companies, the researchers found, saw bigger effects -- an average of 2.3 percent increase in the value of their shares in the wake of the emissions disclosure."
