Clean fuels could reduce deaths from ship smokestacks by 40,000 annually: Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012—almost one-third higher than previously believed, according to the second major study on that topic. The study says that government action to reduce sulfur emissions from shipping fuel (the source of air pollution linked to an increased risk of illness and death) could reduce that toll. The study is in the current issue of ACS’ Environmental Science and Technology, a semi-monthly publication.
