GLOBAL CARBON EMISSIONS DROP 7% THIS YEAR

A locked-down pandemic-struck world cut its carbon dioxide emissions this year by 7%, the biggest drop ever, new preliminary figures show, Seth Borenstein reported for Associated Press (AP).

The Global Carbon Project, an authoritative group of dozens of international scientists who track emissions, calculated that the world will have put 37 billion US tons or 34 billion metric tons (BMT) of carbon dioxide in the air in 2020. That’s down from 40.1 billion US tons (36.4BMT) in 2019, according a study published in the journal Earth System Science Data.

Scientists say this drop is chiefly 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, the chief man-made heat-trapping gas.

“Of course, lockdown is absolutely not the way to tackle climate change,” said study co-author Corinne LeQuere, a climate scientist at the University of East Anglia. The same group of scientists months ago predicted emission drops of 4% to 7%, depending on the progression of COVID-19. A second coronavirus wave and continued travel reductions pushed the decrease to 7%, LeQuere said.

Emissions dropped 12% in the United States and 11% in Europe, but only 1.7% in China. That’s because China had an earlier lockdown with less of a second wave. Also China’s emissions are more industrial based than other countries and its industry was less affected than transportation, LeQuere said.
