Impact of City-Wide Diesel Generator Use on Air Quality in Quito, Ecuador, during a Nationwide Electricity Crisis

Extended blackouts during Ecuador's hydroelectric crisis of 2023/2024 led to significant spikes in urban air pollutants in Quito, with SO2 levels rising by 180%, CO by 43%, NO2 by 39%, and PM2.5 by 20% compared to normal conditions. Conversely, ozone pollution decreased by 6%. The study, which analyzed data from the crisis period against a pre-crisis reference and a year with similar weather, highlights potential respiratory and cardiovascular health risks for Quito's population. It underscores the urgent need for sustainable energy infrastructure and cleaner backup power solutions in developing countries to mitigate the impacts of climate-induced electricity crises.
