On May 12, 2016, NRDC witnessed Wallenius Wilhelmsen Logistics (WWL), the world's largest shipping carrier of automobiles, pledge to limit the sulfur content of fuel used at berth to less than 0.1%, for its entire fleet – a massive victory for clean air around the world. This announcement was inspired by China's Domestic Emission Control Area (DECA) regulation, but goes a step beyond the 0.5% sulfur limit. We commend WWL's bold action and encourage other companies to follow suit. NRDC shared strong enforcement mechanisms from the U.S. and E.U. at WWL's seminar to help all carriers calling at Chinese ports operate on a level playing field and ensure that the regulation delivers the expected environmental benefits. At the event, Mr. Dong Leyi, senior official from National Maritime Safety Administration spoke highly of NRDC's contributions to capacity building for DECA enforcement.
