Abstract:
City carbon footprint evaluation is a process to determine associated activities that emit significant Greenhouse Gases (GHG) within a citys boundary. Identification of these activities is important in understanding the root causes in order to recommend suitable GHG reduction measures. This research aims to study and provide recommendations on city GHG reduction measures based on existing technology and government policies. City carbon footprints are evaluated using activity data in the Muang Phayao Municipality area. Activity data is categorized into three boundaries; Scope 1 Direct Emission, Scope 2 Indirect Emission, and Scope 3 Other Indirect Emissions; using 2018 as the base year. GHG emission in Muang Phayao Municipality in 2018 was 31,408.01 tCO2-eq. Results show that electricity consumption is the most prominent emission source at 49.97%, followed by fuel energy consumption at 33.76%, while agriculture, forestry and other land use was the smallest source at 0.95%. Without intervention, the citys GHG emission will increase to 50,807.37 tCO2-eq by 2030. From studying GHG emissions mitigation capacity, the city can reduce 11,606.29 tCO2-eq within the year 2030 when compared with the base year. To achieve that number, the city has to follow appropriate GHG emission mitigation measures.
