Pandemic lockdowns and containment measures have been a nice breather for the Earth. Travel restrictions have led to an unprecedented decline in mobility worldwide, with CO2 emissions from transportation globally decreasing by more than 10% in 2020, according to a report by the International Energy Agency.
But the drop in carbon emissions is by no means permanent. Demand for transportation, especially aviation and cargo transport, is rebounding as more countries open back up. Decarbonising the transportation sector is a long journey, and relying on temporary travel restrictions and closed-off economies is not a sustainable way for cities to achieve long-term emissions goals.
