Abstract: A new exhaust emission inventory of ocean-going vessels (OGVs) was compiled for Hong Kong by using Automatic Identification System (AIS) data for the first time to determine typical main engine load factors, through vessel speed and operation mode characterization. It was found that in 2007, container vessel was the top emitting vessel type, contributing 9,886, 11,480, 1,173, 521 and 1166 tonnes of SO2, NO x , PM10, VOC and CO, respectively, or about 80%–82% of the emissions. The top five, which also included ocean cruise, oil tanker, conventional cargo vessel and dry bulk carrier, accounted for about 98% of emissions. Emission maps, which add a new spatial dimension to the inventory, show the key emission hot spots in Hong Kong and suggest that a significant portion of emissions were emitted at berth. Scientific evidence about the scale and distribution of ship emissions has contributed in raising public awareness and facilitating stakeholder engagement about the issue. Fair Winds Charter, the world's first industry-led voluntary emissions reduction initiative, is a perfect example of how careful scientific research can be used in public engagement and policy deliberation to help drive voluntary industry actions and then government proposals to control and regulate marine emissions in Hong Kong and the Pearl River Delta region.

The Fair Winds Charter is a good example of public-private-NGO sector collaboration that can create the framework for future legislation covering emissions throughout the Pearl River Delta (PRD). The Fair Winds Charter is the first agreement of its kind. The Charter calls on regional governments to regulate the shipping sector. This report explains the importance of stakeholder engagement in increasing policy understanding and acceptance, the value of data and cross-disciplinary research in air quality and public health for developing a compelling case for policy change; and how the science and stakeholder engagement stimulated regulatory change under the public-private- NGO umbrella of engagement.

This article represents a first attempt to pull together relevant materials with the aim of providing a broad-brush view of how climate change may affect Greater Pearl River Delta (GPRD) region (Hong Kong, Macau and the Pearl River Delta). Among the various consequences of climate change, rising sea levels are a matter of great concern for the GPRD region, which is made vulnerable both by its physical geography (the southern part of the delta lies between - 0.3m to 0.4m relative to mean sea level (MSL)) and its urban development. More in-depth research and modeling remain to be done so that the authorities, business and civil society can better understand climate impacts on the region, but this article shows that climate change could have a big impact on the regional economy, which represents nearly 10% of China's GNP. The paper concludes with a discussion of the measures that government and businesses will need to consider in order to adapt to these future conditions. [ABSTRACT FROM AUTHOR]
