The temporary environmental benefits from the COVID-19 pandemic are coming to an end as economies reopen worldwide.
When the pandemic started in April, businesses closed and transportation dropped as people were forced to stay indoors. This caused a 17% drop in daily carbon emissions when compared to levels recorded at the same time last year. However, by June 11, the drop was only 5%, according to a study published in the journal Nature Climate Change. For climate scientists, the pandemic has made clearer the difficulty of reducing carbon emissions permanently.
“We’re getting to this by stopping all activities, not structural changes, so when people go back to work there’s no reason these emissions wouldn’t go shooting back up,” said Corinne Le Quéré, a professor of climate change science and policy at the U.K.’s University of East Anglia.
Governments would need to encourage low-emissions technologies and encourage the continued use of daily emissions tracking in order to see lasting impacts, according to a Wall Street Journal article. While governments have put more effort into reducing carbon emissions since the 2015 Paris climate accord, emissions have continued to rise. The U.S. has also said it is withdrawing from the deal.
The pandemic has accelerated efforts to move from monthly and yearly reporting to daily monitoring of carbon emissions. Climate scientists hope that these advances will help lead to a better understanding of how governments can move forward in their efforts to reduce emissions in the future.
