Abstract:

The analysis presented in this report demonstrates that Hong Kong can reduce its carbon emissions by 90 per cent by 2050 relative to 2005 levels and offset the remaining 10 per cent which comes from hard-to-abate sectors. To progress towards a net zero emissions future, Hong Kong must begin planning and taking accelerated action now. It needs to adopt a significantly more aggressive decarbonisation target, with annual reductions of 6.6 per cent beginning immediately and continuing through 2050. The greatest potential for reducing emissions comes from improving electricity generation, making buildings more energy efficient and increasing the sustainability of mobility. A net zero emissions economy and society would provide Hong Kong with a cleaner, greener and healthier environment and yield substantial economic and social benefits. Projected reductions in air pollutants would increase life expectancy to the equivalent of about 26,000 lives saved by 2050, and cumulative economic benefits could amount to HK$460 billion.
