The greenhouse effect simply is a natural process to balance greenhouse gas concentration throughout the atmosphere. However, due to anthropogenic activities, this natural effect becomes an environmental problem for the entire world. It tends to occur global warming. The world’s climate always varied naturally, but climate change largely variates due to the concentration of “greenhouse gases” in the earth’s atmosphere since the industrial revolution began. Now overriding this natural variability and leading to irreversible climate changes. If no climate policy interventions are implemented or modified, future climate changes will be caused by harmful effects on Sri Lanka islands. This study focuses on discussing the Sri Lankan contribution to global warming from industries. We mainly discussed four industries’ GHG emission sources and further aim to discuss the Sri Lankan rules and regulations and implementation options.
