The sudden stop of the global economy during the pandemic was followed by a dramatic decrease of Greenhouse gas emissions (GHG). Changes in mobility, consumption and production drove this decline.
For example in the air transport industry, 364 tonnes of CO2 were produced during 2020. This is 221 tonnes of CO2 less than in 2019 (a 42.43% decrease).
The significant reduction of emissions in aviation, as in other transportation industries, shows that it is possible to limit human activities that are highly polluting without compromising income to the same extent.
Now that activities have been reactivated, will we be able to restore growth paths while limiting the recovery of GHG?
