The increasing rate of human-caused greenhouse gas (GHG) emission levels has ledto a significant rise in global temperature. A large number of GHGs are released during the combustion of fossil fuels in end-use sectors. GHG emissions cause global warming and climate change, with CO2 recording for nearly 72% of total GHG emissions. When statistics show that Emissions of carbon dioxide have increased 1.6 times in the last three decades, the importance of researching GHG decreases in different nations becomes even clearer. Even though Malaysia is not specified in Annex 1 of the Kyoto Protocol (KP), this developing country has actively participated in GHG reduction projects under the KP. GHG emissions are increasing in Malaysia as a result of visible growth in industry and a growing population. The Malaysian government has prioritized fuel usage efficiency, optional fuel utilization, and palm tree plantation as key objectives. This review provides an outline of Malaysia's key sources of GHGs and examines the preventive measures that the Malaysian government should adopt to reduce CO2emissions.
