Short summary
The first European SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) wave and associated lockdown provided a unique sensitivity experiment to study air pollution. We find significantly different emission trajectories between classical air pollution and climate gases (e.g., carbon dioxide). The analysis suggests that European policies, shifting residential, public, and commercial energy demand towards cleaner combustion, have helped to improve air quality more than expected.
