Reductions in California's Urban Fossil Fuel CO₂ Emissions During the COVID-19 Pandemic.

ABSTRACT: Fossil fuel carbon dioxide (CO₂) emissions (ffCO₂) constitute the majority of greenhouse gas emissions and are the main determinant of global climate change. The COVID-19 pandemic caused wide-scale disruption to human activity and provided an opportunity to evaluate our capability to detect ffCO₂ emission reductions. Quantifying changes in ffCO₂ levels is especially challenging in cities, where climate mitigation policies are being implemented but local emissions lead to spatially and temporally complex atmospheric mixing ratios. Here, we assess ffCO₂ emission patterns associated with pandemic-induced changes to human activity using direct observations of on-road CO₂ mole fractions in the Los Angeles (LA) urban area and anal
