Greenhouse gas emissions in Hong Kong

This study provides a quantitative review of the emissions of carbon dioxid e (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 e missions in Hong Kong. Among the different typos of fuels coal is identifie d as the major source of CO2, which constitutes about 50% by fuel type. On the other hand, CH4, which mainly comes from waste decomposition, contribut es to 5% of the total GHG emissions. Correlation study revealed that energy consumption and waste quantity were strongly correlated with population an d gross domestic products (GDP), implying that not much has been done in Ho ng Kong to re-mediate GHG emissions. Regression analysis concluded that sup ply side management (fuel switch) was more effective than demand side manag ement (energy conservation) in mitigating CO2 emissions in Hong Kong.
