Abstract
This research aims to quantify the greenhouse gas emissions in accordance with the guidelines of the Thailand Greenhouse Gas Management Organization (Public Organization) and to assess the energy consumption from organizational activities in 2024. Furthermore, the study proposes greenhouse gas mitigation projects based on the methodology of the Thailand Voluntary Emission Reduction Program (T-VER). The case study is conducted in an electrical appliance manufacturing factory. The result revealed that the total greenhouse gas emission was 20,199.56 tonCO2 eq./year or 0.0079 tonCO2 eq/unit, while the total energy consumption was 26,502,490.69 MJ, or 10.41 MJ/unit. The largest sources of greenhouse gas emissions are: 1) Using plastic resin in category 1 from scope 3, 2) Plastic injection molding process in category 10 from scope 3 and 3) Electricity consumptions from scope 2 were discovered at 8,683.34, 5,036.64 and 2,499.48 tonCO2 eq/year, respectively. Therefore, the researcher proposes four potential projects to reduce greenhouse gas emissions, namely: 1) Recovery and recycling of plastic from plastic solid waste, 2) Weight reduction of plastic components in products, 3) Use of renewable energy from solar rooftop and 4) Energy efficiency improvement for lightings. All four projects can reduce energy consumption 5,535,169.20 MJ, corresponding to 8.23 MJ/unit, and decrease greenhouse gas emissions 1,766.70 tonCO2 eq/year, corresponding to 0.0072 tonCO2 eq/unit.
