construction site emissions , and the remaining 2 % from the transportation of construction material .
As shown in Figure 3 , out of the average total GHG emissions for the years 2017 – 2019 , 7 % was from the construction site , 90 % from fuel consumption , 6 % from electricity consumption and the remaining 4 % was from waste treatment and transportation . For fuel consumption , bitumen was identified as the main contributor ( 42 %), followed by diesel ( 35 %), lubricant ( 12 %), and liquefied petroleum gases ( LPG ) ( 11 %).
Projection of Baseline GHG Emissions ( 2020 to 2050 ) The projection of GHG emissions contributed by the construction industry ( cradle-to-site ) in Malaysia for the year 2020 to 2050 was carried out under this study . The material consumption , fuel consumption , electricity consumption , and waste projections up to 2050 were estimated using the econometric approach . The economic indicators used in a projection such as gross domestic product ( GDP ) were taken from the

Department of Statistics Malaysia ( DOSM ), Economic Planning Unit ( EPU ), and the World Bank . The historical correlation between consumption of construction materials and energy demand , as well as macroeconomic and activity indicators , were derived by regression analysis . It was projected that the total GHG emissions of 147 million tCO 2 eq . ( 92 % increase as compared to 2020 ) will be emitted from the construction industry ( cradle-to-site only ) by the
