Finally, some data. A couple of weeks ago Civic Exchange and two Hong Kong universities
released a report detailing the extent of emissions from ships in the Pearl River Delta region, and their public health impact.
It’s a groundbreaking study. Using 2008 data, researchers from HKUST did a ship emissions inventory of vessels activity across the PRD. They then calculated the dispersion of the pollutants, which showed that Shenzhen and Hong Kong have the most ship emissions, ahead of other coastal PRD regions such as Zhongshan and Dongguan, and outer PRD regions, like Foshan and Huizhou.
