Technology has slashed CLP power generation emissions since 1990
Switch to nuclear and gas power, and fitting scrubbers to coal-fired plant, brought 80pc cut in pollution since 1990 as output soared
Hong Kong has a global reputation as a dynamic, power-hungry city with a growing carbon footprint and sometimes eye-wateringly high levels of air pollution.
The impact of pollution on people's health and the liveability of Hong Kong has rightly become one of the city's primary concerns and has generated years of heated debate. But facts can sometimes disappear in the smog of heated discussions - and what is often overlooked is that our city has also scored some notable victories in tackling some of the sources of pollution.
Road and marine traffic have become the largest local sources of air pollutants, while emissions from electricity generation have been reduced. Hong Kong's largest power company, CLP, has reduced its emissions from power generation by about 80 per cent since 1990 while simultaneously increasing production by the same percentage to meet the demand.
This dramatic fall in emissions has been achieved through the successful application of various clean-air technologies, initiation of innovative operational measures and a commitment to monitor emissions closely and continually. CLP has implemented three major technologies in conjunction with various operational measures such as using ultra-low-sulphur coal to achieve this significant reduction.
The three major technological milestones were the import of nuclear power in 1994, the introduction of natural-gas-fired power generation in 1996, and the installation of large-scale advanced emission-control equipment in 2010.
These efforts, in conjunction with significant improvements in both the hardware and software of emissions control, sent the levels of pollutants produced by electricity generation tumbling.
