A survey of 11 hotels in Hong Kong was carried out to collect three years' energy consumption data. Regression analysis indicated that gross floor area was a major and statistically acceptable factor in explaining the gas consumption in new hotels. Based on past consumption data and some established pollutant emission factors, the amount of sulphur dioxides, nitrogen dioxides, carbon dioxides and particulate created by the Hong Kong hotel industry's gas usage during a 10-year period from 1989-1998 was estimated. The study predicts the increase in these amounts in 1999-2003 accompanying the rise in the number of hotels. The findings indicate that emissions will rise by nearly 40% in the next few years, requiring urgent discussions. The study also finds that a heat pump running on coal-fired electricity and with a coefficient of performance (COP) greater than 3 could produce lower level emissions than a gas-fired boiler. It is further suggested that an effective method to reduce the emissions is to substitute naptha with natural gas as the fuel for generating town gas and electricity. We believe the hotel industry should adopt a more proactive approach to reduce gas usage and propose the inclusion of environmental reporting in trade journals. Chan and J.C. Lam.
