KENSINGTON, Maryland  — The world cut its daily carbon dioxide emissions by 17% at the peak of the pandemic shutdown last month, a new study found.

But with life and heat-trapping gas levels inching back toward normal, the brief pollution break will likely be “a drop in the ocean” when it comes to climate change, scientists said.

In their study of carbon dioxide emissions during the coronavirus pandemic, an international team of scientists calculated that pollution levels are heading back up — and for the year will end up between 4% and 7% lower than 2019 levels. That’s still the biggest annual drop in carbon emissions since World War II.

It’ll be 7% if the strictest lockdown rules remain all year long across much of the globe, 4% if they are lifted soon.

For a week in April, the United States cut its carbon dioxide levels by about one-third. China, the world’s biggest emitter of heat-trapping gases, sliced its carbon pollution by nearly a quarter in February, according to a study Tuesday in the journal Nature Climate Change. India and Europe cut emissions by 26% and 27% respectively.

The biggest global drop was from April 4 through 9 when the world was spewing 18.7 million tons of carbon pollution a day less than it was doing on New Year’s Day.

Such low global emission levels haven’t been recorded since 2006. But if the world returns to its slowly increasing pollution levels next year, the temporary reduction amounts to ‘’a drop in the ocean,” said study lead author Corinne LeQuere, a climate scientist at the University of East Anglia.

“It’s like you have a bath filled with water and you’re turning off the tap for 10 seconds,” she said.

By April 30, the world carbon pollution levels had grown by 3.3 million tons a day from its low point earlier in the month. Carbon dioxide stays in the air for about a century.

Outside experts praised the study as the most comprehensive yet, saying it shows how much effort is needed to prevent dangerous levels of further global warming.

“That underscores a simple truth: Individual behavior alone … won’t get us there,” Pennsylvania State University climate scientist Michael Mann, who wasn’t part of the study, said in an email. “We need fundamental structural change.”

If the world could keep up annual emission cuts like this without a pandemic for a couple decades, there’s a decent chance Earth can avoid warming another 1.8 degrees of warming from now, study authors said. But getting the type of yearly cuts to reach that international goal is unlikely, they said.

If next year returns to 2019 pollution levels, it means the world has only bought about a year’s delay in hitting the extra 1.8 degrees of warming that leaders are trying to avoid, LeQuere said. That level could still occur anywhere from 2050 to 2070, the authors said.

The study was carried out by Global Carbon Project, a consortium of international scientists that produces the authoritative annual estimate of carbon dioxide emissions. They looked at 450 databases showing daily energy use and introduced a measurement scale for pandemic-related societal “confinement” in its estimates.

Nearly half the emission reductions came from less transportation pollution, mostly involving cars and trucks, the authors said. By contrast, the study found that drastic reductions in air travel only accounted for 10% of the overall pollution drop.

In the U.S., the biggest pollution declines were seen in California and Washington with plunges of more than 40%.
