GHG evaluation and mitigation planning for low carbon city case study: Dan Sai Municipality

Abstract

© 2019 In the era of globalization, the economy has expanded, leading to an increase in population and the growth of the city dramatically. The municipalities as local administrators for the being and the quality of life of people in the city. However, the activities in the city such as fuel consumption of housing and transportation, electricity use, waste management like wastewater and waste produce both direct and indirect greenhouse gases, increasing many impacts of climate change. The concept of “low carbon city” has been applied to local government in Thailand. This research aims to evaluate city's greenhouse gas emissions in a case study of Dan Sai municipality based on the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories guideline (GPC), divided into three scopes are scope 1, direct greenhouse gas emissions, scope 2, indirect greenhouse gas emissions from the electricity use and scope 3, other indirect greenhouse gas emissions. According to the study of the city's greenhouse gas emissions in year 2016, was found that Dan Sai municipality had a greenhouse gas emission of 22,925.66 tCO2eq, equivalent to 5.95 tCO2eq/person/year of the amount of greenhouse gas emissions per capita, The amount of greenhouse gas emissions per household is 11.84 tCO2eq/household/year and the amount of greenhouse gas emissions per area is 2,999.82 tCO2eq/square kilometer/year. And from the assessing results of the alternative options to reduce greenhouse gases by analyzing the final cost of the three options, that are increasing the number of solar rooftops, increasing the use of household LED bulbs and refining waste management using RDF technology, found that the final cost was −175.48, 87.53 and −61.72 Baht/kgCO2eq, respectively. This project model is a sustainable city developed into a low carbon city in the future.
