ESTIMATION OF GREENHOUSE GAS EMISSIONS FROM HOUSEHOLD ACTIVITIES DURING THE COVID-19 PANDEMIC IN BINJAI CITY, NORTH SUMATERA (a) Environmental Engineering, Faculty of Engineering, Universitas Sumatera Utara, Jalan Almamater Kampus USU, Medan 20155 Abstract Household activities have the potential to produce greenhouse gas emissions. The government^s policy to work and study from home during the COVID-19 pandemic certainly affects greenhouse gas emissions produced by household activities, starting from the use of energy and waste and liquid waste produced, so it is necessary to carry out an emission inventory. The purpose of this study is to calculate greenhouse gas emissions (CO2 and CH4) from household activities in Binjai City during the Covid-19 pandemic and determine emission reduction scenarios that can be carried out in Binjai City. The calculation method used is based on the 2006 IPCC (Intergovernmental Panel in Climate Change) guidelines. CO2 emissions resulting from the use of LPG are 2025.82 tons CO2eq/month, the use of fuel for daily transportation activities is 3,484.848 tons CO2eq/month and electricity usage is 151,939 Ton CO2eq/month. CH4 emissions produced from domestic liquid waste are 12,012.461 tons CO2eq/month and household waste are 27,536 tons CO2eq/month. There are 4 scenarios for reducing CO2 emissions. Several actions to reduce CO2 emissions from household activities, namely using a bicycle for a distance of 5 km can reduce up to 39% CO2 emissions- Turning off lights and electronic devices when not in use can reduce up to 79% CO2 emissions. Efforts to reduce CH4 emissions are converting CH4 gas into electricity with the potential for electricity generated from CH4 domestic liquid waste in Binjai City of 97,952.182 KWh/year. Composting household waste can reduce up to 90% of CH4 emissions. Keywords: Climate change, Emission Inventory, Household Activities, Pandemic Covid-19 Topic: Climate change and global warming |
