World carbon dioxide emissions plummet 7% in 2020
A locked-down pandemic- struck world cut its carbon dioxide emissions this year by 7%, the biggest drop ever, new preliminary figures show.
The Global Carbon Project, which tracks emissions, calculated that the world will have released 34 billion metric tons of carbon dioxide into the air in 2020. That's down from 36.4 billion metric tons in 2019, according to a study published on Dec. 10 in the journal Earth System Science Data.
Scientists say this drop is mainly because people are staying home, traveling less by car and plane, and that emissions are expected to jump back up after the pandemic ends. Ground transportation makes up about one-fifth of emissions of carbon dioxide.
Chris Field, director of the Stanford Woods Institute for the Environment, thinks emissions will increase after the pandemic, but said, "I am optimistic that we have, as a society, learned some lessons that may help decrease emissions in the future." (AP)
