Our CO2 emissions are mainly associated with direct energy use. Therefore the One Tonne Challenge focus on saving energy. On average, each Hong Kong person consumed 41.84 Giga Joules (GJ) of energy in 2004. Transportation accounted for 36% of the energy consumption, while over 24% of the electricity and 50% of the gas are consumed at our homes. The power plants in Hong Kong use mainly coal and natural gas (both are fossil fuel) as fuel to generate electricity.
Each large 1000 Megawatt (MW) coal-fired plant typically emits 5.6 million tonnes of CO2 per year. For every litre of petrol used, a car will emit 2.4 kg from the exhaust (mainly CO2). On average, the greenhouse gas emission of each Hong Kong person is equivalent to 6.5 tonnes of CO2 in 2004. This figure does not include the indirect CO2 emissions from the manufacturing and transportation of the services and products we enjoy!
