Following President Xi Jinping's announcement at the United Nations in 2020 that China would endeavor to achieve peak carbon emissions in 2030 and carbon neutrality before 2060, the Hong Kong government released "Hong Kong's Climate Action Plan 2050" in 2021, setting out the following targets for CO2 reduction and energy use reduction from buildings:

• To reduce Hong Kong's carbon emissions by 50% before 2035 as compared to the 2005 level and to achieve carbon neutrality before 2050
• To reduce commercial buildings' electricity consumption by 30% to 40% and that of residential buildings by 20% to 30% from the 2015 level by 2050, and to achieve half of the above targets by 2035
