"The single most important factor in the drop was emission reductions from the transport sector, particularly road transport, suggesting that the actual lockdowns truly kept people at home and traveling less nationally and internationally," Canadell tells Inverse.
"Where contexts remain stable, if strong habits have been formed, we would predict that the behavior will persist after lock-down," Phillippa Lally tells Inverse. Lally is a senior research fellow at University College London’s Department of Behavioral Science and Health.
"Habits are about context...if previous pre-lockdown habit cues return, then old habits are likely to again guide behavior," says Lally.
"If people want to maintain or form pro-environmental behaviors, they need to create an environment that is supportive of those choices," Lally says.
"It would also help to get the things you need, like your helmet, ready the night before, and you could even put the car keys out of the way," Lally says.
