Will a surge in car journeys lead to a CO2 rebound?

Recent research has shown that daily global emissions of CO2 fell by 17% at the peak of the government-implemented shutdowns as a result of Covid-19, with a key factor being the reduction in cars on the road, as reported in the BBC. Professor Frank Kelly noted the role other pollutants play in global emissions, particularly diesel car emissions, noting research undertaken that found a mismatch between emissions declared by the car firms and real readings on the road. As people return to work, and their cars, the impact on climate change needs to continue to be monitored.
