In Health Care, It Pays to be Green

摘要

Firms have a responsibility to their shareholders to maximize their financial performance however they are increasingly scrutinized for environmental practices as well. These two objectives are often thought to be in conflict; it can be costly to be a good steward of the environment however it may be more costly in the long run to ignore societal pressures and environmental impacts. While various studies provide ambiguous and sometimes contradictory results, we conduct a rigorous analysis of the health care sector using Trucost’s Environmental Impact Score and financial data. The study uses regression analysis to identify the extent to which the benefit to the firm of reducing its environmental impact is financially beneficial. In the health care sector, an increase in the environmental impact score of 1 unit is correlated with an increase of 4% of their earnings per share. Improving the environmental bottom line improves the financial bottom line.
