Kensington (United States), May 20: 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 (17 million metric 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 (3 million metric 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 (1 degree Celsius) 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 (1 degree Celsius) 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 US, the biggest pollution declines were seen in California and Washington with plunges of more than 40%.

As Peru begins to ease its strict coronavirus lockdown, the country's biggest LGBTQ nightclub opened its doors on Tuesday, but there will be no nighttime revellers; its dance floor will instead be filled with shelves stocked with groceries.

Instead of slinging cocktails at the bar or dancing on stage, ValeTodo Downtown's famed staff of drag queens will sell customers daily household products as the space reopens as a market while nightclubs are ordered to remain closed.

The Peruvian government will lift the lockdown in most regions of the country at the beginning of July but will keep borders closed, as well as nightclubs and bars.

The lockdown has been a struggle for the club's 120 employees like drag queen Belaluh McQueen. Her life completely changed when the government announced the quarantine. Her nights were spent at home, rather than performing as a dancer at the club in vivid-coloured costumes.

"I was very depressed because I have been doing this art for years, but you have to adapt to new challenges for the future," said McQueen, who is identified by her stage name.

Now McQueen is back to work as a grocery store employee, wearing a sequined suit, high heels and a mask. A DJ will play club music as patrons shop. "We have a new job opportunity," McQueen added.

Renamed as Downtown Market, the club, which has been a mainstay hallmark of the local LGBTQ community, ushered in its reopening with an inauguration ceremony.

"Before, I used to come here to dance and have a good time, but now we come to buy," said Alexandra Herrera, a regular attendee of the club. "The thing is to reinvent yourself."

The club's general manager, Claudia Achuy, said that the pandemic impacted the heart of Lima nightlife, but she chose to reopen as a market rather than risk cutting staff. "If we had just stayed as a nightclub we did not have a close horizon or a way of working," Achuy said.

Peru's confirmed coronavirus cases rose to 282,364 with 9,504 associated deaths on Monday, according to government data. It has the second-highest outbreak in Latin America after Brazil, according to a Reuters tally.

Washington, May 6: At a time when the coronavirus pandemic has squeezed them, multi-national companies in America are laying off workers while paying cash dividends to their shareholders. Thus making the workers bear the brunt of the sacrifices while the shareholders continue to collect.

The Washington Post said in one of its reports that five big American companies have paid a combined USD 700 million to shareholders while cutting jobs, closing plants and leaving thousands of their workers filing for unemployment benefits.

Since the pandemic was declared an emergency, Caterpillar has suspended operations at two plants and a foundry, Levi Strauss has closed stores, and toolmaker Stanley Black & Decker has been planning layoffs and furloughs.

Steelcase, an office furniture manufacturer, and World Wrestling Entertainment have also shed employees.

Executives of those companies told the Post that the layoffs support the long-term health of their companies, and often the executives are giving up a piece of their salaries. Furloughed workers can apply for unemployment benefits.

But distributing millions of dollars to shareholders while leaving many workers without a paycheck is unfair, critics argue, and belies the repeated statements from executives about their concern for employees' welfare during the coronavirus crisis.

Caterpillar, for example, announced a USD 500 million distribution to shareholders April 8, about two weeks after indicating that operations at some plants would stop. The company however declined to divulge how many workers are affected.

"We are taking a variety of actions globally, but we aren't going to discuss the number of impacted people," spokeswoman of the company, Kate Kenny, said in a reply to an email by the Post.

This spate of dividends is also likely to revive long-standing debates about economic rewards.

"There are no hard-and-fast rules about this," said Amy Borrus, deputy director of the Council of Institutional Investors, a group that argues for shareholder rights and represents pension funds and other long-term investors.

Many large US companies choose to issue a regular, quarterly dividend to shareholders, often increasing it, and they boast about these payments because they help keep the share price higher than it might otherwise be. Those companies might be reluctant to announce that they are cutting or suspending their dividend during a crisis, Borrus was further quoted as saying.

But "companies have to be mindful of the optics of paying dividends if they're laying off thousands of workers," she added.

On March 26, Caterpillar had announced that because of the pandemic, it was "temporarily suspending operations at certain facilities." Two plants, in East Peoria, Ill., and Lafayette, Ind., were coming to a halt, as well as a foundry in Mapleton, Ill., according to news reports.

"We are taking a variety of actions at our global facilities to reduce production due to weaker customer demand, potential supply constraints and the spread of the covid-19 pandemic and related government actions," Kenny said via email.

"These actions include temporary facility shutdowns, indefinite or temporary layoffs," she added.

Similarly, Levi Strauss announced April 7 that the company would stop paying store workers, and about 4,000 are now on furlough. On the same day, the company announced that it was returning USD 32 million to shareholders.

"As this human and economic tragedy unfolds globally over the coming months, we are taking swift and decisive action that will ensure we remain a winner in our industry," Chip Bergh, president and chief executive of the company, also told the Post.

Stanley Black & Decker announced on April 2 that it was planning furloughs and layoffs because of the pandemic. Two weeks later, it issued a dividend to shareholders of about USD 106 million.

The notion that a company's primary purpose is to serve shareholders gained prominence in the 1980s but has come under attack in recent years, even from business executives, the newspaper reported.

Corporate decisions to suspend dividends and buybacks are complex, however, and it is difficult to know whether these suspensions of dividend and buyback programs were motivated by a desire to conserve cash in anticipation of bad times, and how much they are prompted by a sense of obligation to employees.

Over recent decades, the mandate to "maximize shareholder value" has become orthodoxy, for many, and it is often unclear what motivates companies to pare dividends or buybacks for shareholders, said William Lazonick, an emeritus economics professor at the University of Massachusetts at Lowell, who has been one of the leading critics of companies that distribute cash to shareholders through stock buybacks and dividends rather than reinvesting the profits into employees, innovation and production.
