The United States topped the overall rankings, which sought to determine “which countries are most active in using green tax incentives and penalties to drive sustainable corporate behavior and achieve green policy objectives,” followed by Japan, the United Kingdom and France. Mexico and Russia took up the final two slots, 20 and 21, respectively. The findings weight tax penalties higher on the list than tax incentives. That’s because that while a company may choose whether or not to take advantage of a tax incentive, it cannot avoid the penalties.
