Since 2010, the SAR government has continued to implement policies and measures to mitigate greenhouse gas emissions. In 2014, the &quot;Hong Kong Climate Change Strategy and Action Plan&quot; first proposed the quantitative goal of greenhouse gas emission reduction, that is, by 2020, the carbon emission intensity will be reduced by 50% to 60% compared with 2005. By taking various measures, Hong Kong has made significant progress in controlling greenhouse gas emissions: from 2010 to 2016, Hong Kong&#39;s population increased by 4.4%, the real GDP of the region increased by 2.9%, and carbon dioxide emissions per unit of GDP decreased by about 29%. Greenhouse gas emissions were maintained at around 5.7 tons of carbon dioxide equivalent.
