Challenges toward Zero Carbon Hong Kong (邁向零碳香港的挑戰)

The Hong Kong Climathon focuses on 4 specific areas:

(1) Heat Island Effect Hong Kong is a densely populated city, localized urbanization leads to an urban heat island effect. The tall and compact buildings and the emission of exhausted gases from air-cons in the buildings trap air pollutants, worsening air pollution and increase reliance on air con etc. The rate of average temperature rise was faster in the latter half of the 20th century compared to the figure of 1885 to 2015, The number of hot nights and very hot days in Hong Kong has also increased and will possibly double in 2100. Winter could disappear in HK. Many people are living in tiny flats or sub-divided unit (average area only ~47.8 ft²) with poor ventilation. Temperature in summer in such flats could rise as high as 38.5 ºC . Rise in temperature greatly affects these low income families.

(2) Energy Choice According to information provided by the government, there are no indigenous energy resources in Hong Kong, we have to derive energy supplies almost entirely from external sources. Energy is either imported directly (as in the case of oil products and coal products), or produced through some intermediate transformation processes using imported fuel inputs (as in the case of electricity and towngas). The Fuel mix in 2013 is Coal 57%, imported nuclear power 22%, natural gas 21%. Only a minimal portion of energy comes from renewable energy such as solar energy and solar energy.

(3) Waste Management According to information provided by the government, each year, around 6 million tonnes of MSW Municipal solid waste are generated in Hong Kong, over half of which is disposed of in the three strategic landfills and they will be full, one by one, in the mid to late 2010s. Currently, only 35% of municipal solid waste generated in Hong Kong is recycled. Hong Kong needs a more sustainable way to deal with waste.

(4) Community Plan or infrastructure improvement under extreme weather conditions Extreme weather conditions appear in Hong Kong more often than before. In 2016, there were 38 days with Very Hot Weather Warning (highest in Hong Kong record) and 12 records of extreme weather (broke the Hong Kong record) Unusual precipitation pattern, unusual number of hot nights, very hot days and cold days have been observed, and the annual mean temperature increased 0.12 degree Celsius per decade from 1885 to 2016.
