Abstract
The activities of several sectors cause an increase in the amount of greenhouse gas emissions. Household activities also produce greenhouse gas emissions, mainly from cooking, electricity use, solid waste, and wastewater. The dominant greenhouse gas emissions from household activities are CO2, CH4, and N2O. This study aims to inventory greenhouse gas emissions from household activities in Medan City and determine several mitigation scenarios in reducing greenhouse gas emissions from household activities. The method used in calculating greenhouse gas emissions is the IPCC method. The results of an inventory of GHG emissions from household activities in Medan City for energy consumption (LPG and electricity) are 1.16 million tons CO2e/year, household solid waste is 36801.5 tons CO2e/year, and household wastewater is 198723.12 tons CO2e/year. The scenario of replacing LPG with an induction stove can reduce GHG emissions by an average of 21.08%, the design of using solar panels on the roof can reduce GHG emissions by an average of 30.19%, the composting scenario can reduce GHG emissions by an average of 0.38% and utilization CH4 from household wastewater as electrical energy can reduce GHG emissions by 1.23%.
