Ships calling at Yangtze River Delta cities will have to burn low sulphur fuel from 1 April 2016, Chinese authorities have confirmed.
The decision affects the ports of Shanghai, Zhoushan, Ningbo, Suzhou including Zhanjiagang, Changshu and Taicang and Nantong.
In early December 2015, China announced the creation of three Emission Control Areas (ECAs) in the Pearl River Delta (PRD), Yangtze River Delta (YRD) and Bohai Bay, in an effort to reduce air pollution from shipping.
