Trends in household energy-related GHG emissions during COVID-19 in four Chilean cities

The coronavirus disease 2019 (COVID-19) pandemic has strongly affected economies and human lifestyles globally. changes observed in domestic energy consumption patterns have had an impact on household greenhouse gas (GHG) emissions. Since GHG emissions inventories are only available at the country level annual intervals, most studies calculated local emission variations by extrapolating with smaller time territorial scale data. This research presents a bottom-up method, based exploitation of survey addressed to 1200 households, that provides information calculate directly variation their energy-related emissions, without need for extrapolations. method been applied four medium-sized Chilean cities serious air quality problems. Given high correlation between atmospheric pollutants such as NOx CO2 we estimate before appearance COVID-19, per capita were already high. results show space heating-related increased moderately (between 1 6%), while from electricity non-heating uses significantly 8 23%). harmed economy, highlighting importance considering socioeconomic aspects when assessing COVID-19 its entirety.
