Greenhouse gas emissions in Hong Kong

Abstract

This study provides a quantitative review of the emissions of carbon dioxide (CO2) and methane (CH4), the two most significant greenhouse gases (GHGs) in Hong Kong. Study indicated that CO2 accounts for 90% of the local GHG emissions in Hong Kong. Among the different types of fuels coal is identified as the major source of CO2, which constitutes about 50% by fuel type. On the other hand, CH4, which mainly comes from waste decomposition, contributes to 5% of the total GHG emissions. Correlation study revealed that energy consumption and waste quantity were strongly correlated with population and gross domestic products (GDP), implying that not much has been done in Hong Kong to re-mediate GHG emissions. Regression analysis concluded that supply side management (fuel switch) was more effective than demand side management (energy conservation) in mitigating CO2 emissions in Hong Kong.
