The main source of CO2 is power source of automobile and industry that are contributing the main role for these CO2 emissions. But these sectors are also very important for economic growth and developments. The aim of this study is to examine the current status and identify the future trend of energy demand and supply and its impacts on CO2 emissions in Malaysia. Approach: The data for analysis was obtained from the secondary sources. Results: The study discovered that the highest proportion of CO2 emissions comes from energy sector. The future trend of energy demand and supply was estimated by the forecasting polynomial curve fitting method. The increase rate of energy supply and demand can rich up to 170 and 160% respectively during the year 2020 if the current situation last long. The study showed a linear trend of increasing intensity of energy and CO2 emission with respect to Gross Domestic Product (GDP) by the year 2020. Conclusion: A significant share of CO2 emissions can be avoided through improved energy efficiency while providing the same or higher level of energy services. In this regard, greater use of energy efficient, renewable energy and green technologies or options and behavioural changes can substantially reduce CO2 emissions from the energy sector.
