Abstract

This research aims to evaluate and analyze the carbon footprint of J.S. Union Construction Partnership Limited, a pile driving contractor operating in Northern Thailand. The study covers the period from January 1, 2022, to December 31, 2022, following the carbon footprint assessment guidelines established by the Thailand Greenhouse Gas Management Organization (TGO). The analysis includes three scopes: Scope 1 – direct greenhouse gas emissions from the organization’s activities, Scope 2 – indirect emissions from energy consumption, and Scope 3 – indirect emissions from other sources associated with the organization’s operations. The study found that the total greenhouse gas emissions of the organization amounted to 885.5311 tons of carbon dioxide equivalent per year.The majority of the organization’s greenhouse gas emissions come from Scope 3 activities, accounting for 92.44% of total emissions, equivalent to 818.5559 tons of CO₂ equivalent per year. These Scope 3 activities include the purchase of raw materials, transportation, and waste disposal. Scope 1, which covers direct emissions from fuel combustion in machinery and vehicles, accounts for 64.0888 tons of CO₂ equivalent per year, representing 7.24% of the total emissions. Scope 2, involving indirect emissions from electricity usage, accounts for 2.8864 tons of CO₂ equivalent per year or 0.32% of total emissions. The analysis suggests that the organization should focus on reducing emissions from Scope 3, as it contributes the most to the overall carbon footprint. Additionally, reducing fuel consumption in Scope 1 and improving energy efficiency in Scope 2 can further decrease total emissions. The study provides valuable insights for the organization to develop effective carbon footprint management strategies, supporting long-term environmental sustainability and reducing overall greenhouse gas emissions.
