On July 15, the European Commission proposed legislation that would bring EU limits on the sulfur content of shipping fuels into line with International Maritime Organization (IMO) standards. Under the proposed legislation, sulfur content would be cut in stages from the current limit of 4.5 percent by weight to 0.5 percent in 2020. In other more sensitive maritime areas, designated as sulfur emission control areas (SECAs), the limit would be cut from the current 1 percent to 0.1 percent by 2015.
