India Air Pollution Crisis Worsens: Government Plans to Spray Capital With Water

Health + Wellness

A four-day old noxious blanket of smog resting on the Indian capital, New Delhi, that officials expect to worsen over the weekend has prompted a plan to spray water over the city.

On Friday, the government announced, in an unprecedented move, it was finalizing plans to spray water from 100 meters above the city, Reuters reported. It remains unclear how much of the densely populated city of 22 million would be sprayed.


Government officials have closed 6,000 schools, banned all but the most essential commercial trucks, and are re-introducing an "odd-even" scheme which allows vehicle with plates ending in an odd number to operate on one day and even-numbered vehicles the next day.

Despite these measures, the air in New Deli has remained "hazardous" for days. Illegal crop burning, vehicle emissions, industrial pollution and dust from sprawling construction sites have contributed to the pollution emergency. By 11 am on Friday, the U.S. embassy air quality data for PM 2.5 showed levels had reached 550, while the safe limit is 50, according to U.S. embassy standards.

PM 2.5 is particulate matter about 30 times finer than human hair that can be inhaled into the lungs and blood stream, causing cardiac arrest, strokes, lung cancer and a host of other respiratory diseases.

Residents in New Delhi are reporting burning eyes, headaches and nausea. The air is filled with heavy metals and other carcinogens at 30 times WHO limits. Medical professionals consider those levels of pollution at least as harmful as 50 cigarettes a day.

The situation is so dire that doctors are seeing a change in health demographics. Doctors are now reporting that half of their lung cancer patients in New Delhi are non-smokers. Earlier in the week, Chief Minister Arvind Kejriwal, the leader of Delhi, called the capital a "gas chamber."

New Delhi is surrounded by thirteen coal-driven power plants all lying within 185-mile radius of the city. The government ordered one of these plants closed in an attempt to mitigate the pollution. But Delhi's pollution woes in part lie outside of the city. Delhi is neighbored by Punjab and Haryana—large agrarian states that burn millions of tons of crop waste every year around October in preparation for the winter wheat crop.

The National Green Tribunal, an Indian environmental governing body, previously directed the Delhi government and neighboring states to halt the burning of crop residue, but without sufficient funds for machinery, the practice continues. Government data shows the federal government had committed nearly $20 million to Punjab, Haryana, Rajasthan and Uttar Pradesh to help manage crop residue and farm mechanization. Government figures also showed that Punjab had not utilized the fund.

Unless these regions are able to cut local pollution, New Delhi's crisis will likely continue, experts warn.

In early October, Britain's Prince William teamed up with conservationist David Attenborough to launch the Earthshot Prize, a new award for environmentalist innovation. The Earthshot brands itself the "most prestigious global environment prize in history."

The world-famous wildlife broadcaster and his royal sidekick appear to have played an active role in the prize's inception, and media coverage has focused largely on them as the faces of the campaign.

But the pair are only the frontmen of a much larger movement which has been in development for several years. In addition to a panel of experts who will decide on the winners, the prize's formation took advice from the World Wildlife Fund, Greenpeace and the Jack Ma Foundation.

With more and more global attention on the climate crisis, celebrity endorsement of environmental causes has become more common. But why do environmental causes recruit famous faces for their campaigns? And what difference can it make?

'Count Me In'

"We need celebrities to reach those people who we cannot reach ourselves," says Sarah Marchildon from the United Nations Climate Change secretariat (UNFCCC) in Bonn, Germany.

Marchildon is a proponent of the use of celebrities to raise awareness of environmental causes. In addition to promoting a selection of climate ambassadors who represent the UN on sustainability issues, Marchildon's team has produced videos with well-known narrators from the entertainment world: among them, Morgan Freeman and Mark Ruffalo.

"We choose celebrities who have a lifestyle where they are already talking about these issues," Marchildon explains.

"Sometimes they reach out to us themselves, as David Attenborough did recently. And then they can promote the videos on their own social channels which reach more people than we do — for example, if they have 20 million followers and we have 750,000."

Environmental groups focused on their own domestic markets are also taking this approach. One Germany-based organization that uses celebrities in campaigns is the German Zero NGO. Set up in 2019, it advocates for a climate-neutral Germany by 2035.

German Zero produced a video in March 2020 introducing the campaign with "66 celebrities" that supported the campaign, among them Deutschland 83 actor Jonas Nay and former professional footballer Andre Schürrle. They solicit support as well as financial contributions from viewers.

"Count me in," they say, pointing toward the camera. "You too?"

"We are incredibly grateful for the VIPs in our videos," says German Zero spokeswoman Eva-Maria McCormack.

Assessing Success Is Complex

But quantifying the effectiveness of celebrity endorsement of campaigns is not a straightforward process.

"In order to measure effectiveness, first of all you need to define what is meant by success," says Alegria Olmedo, a researcher at the Zoology Department at the University of Oxford.

Olmedo is the author of a study looking at a range of campaigns concerning pangolin consumption, fronted by local and Western celebrities, in Vietnam and China. But she says her biggest stumbling block was knowing how to measure a campaign's success.

"You need a clear theory of change," explains Olmedo. "Have the celebrities actually helped in achieving the campaign's goals? And how do you quantify these goals? Maybe it is increased donations or higher engagement with a cause."

A popular campaign in China in recent years saw famous chefs Zhao Danian and Shu Yi pledge to abstain from cooking endangered wildlife. While the pledge achieved widespread recognition, both Olmedo and Marchildon say it's difficult to know whether it made any difference to people's actions.

"In life we see a thousand messages every day, and it is very hard to pinpoint whether one campaign has actually made a difference in people's behavior," she explains.

Awareness Is Not Enough

Many campaigns that feature celebrities focus on raising awareness rather than on concrete action — which, for researcher Olmedo, raises a further problem in identifying effectiveness.

"Reach should never be a success outcome," she says. "Many campaigns say they reached a certain number of people on social media. But there has been a lot of research that shows that simply giving people information does not mean they are actually going to remember it or act upon it."

But anecdotal evidence from campaigns may suggest reach can make an active difference.

"Our VIP video is by far the most watched on our social media channels," McCormack from German Zero says. "People respond to it very directly. A lot of volunteers of all ages heard about us through that video."

However, some marketing studies have shown that celebrity endorsement of a cause or product can distract from the issue itself, as people only remember the person, not the content of what they were saying.

Choosing the Right Celebrity

Celebrity choice is also very important. Campaigns that use famous faces are often aiming to appeal to members of the public who do not necessarily follow green issues.

For certain campaigns with clear target audiences, choosing a climate scientist or well-known environmentalist rather than a celebrity could be more appealing — Attenborough is a classic example. For others, images and videos involving cute animals may be more likely to get a message heard than attaching a famous face.

"We choose celebrities who have a lifestyle where they are already talking about these issues," says Marchildon from the UN. "You need figures with credibility."

McCormack cites the example of Katharine Hayhoe, an environmental scientist who is also an evangelical Christian. In the southern United States, Hayhoe has become a celebrity in her own right, appealing to an audience that might not normally be interested in the messages of climate scientists.

But as soon as you get a celebrity involved, campaigns also put themselves at risk of the whims of that celebrity. Prince William and younger members of the royal family have come under fire in recent years for alleged hypocrisy for their backing of environmental campaigns while simultaneously using private jets to fly around the world.

But Does It Really Work?

While environmental campaigns hope that endorsement from well-known figures can boost a campaign, there is little research to back this up.

"The biggest finding [from my study] was that we were unable to produce any evidence that shows that celebrity endorsement of environmental causes makes any difference," says Olmedo.

This will come as a blow to many campaigns that have invested time and effort into relationships with celebrity ambassadors. But for many, the personal message that many celebrities offer in videos like that produced by German Zero and campaigns like the Earthshot Prize are what counts.

The research may not prove this conclusively — but if the public believes a person they respect deeply personally cares about an important issue, they are perhaps more likely to care too.

"I personally believe in the power this can have," says Marchildon. "And if having a celebrity involved can get a single 16-year-old future leader thinking about environmentalist issues — that is enough."
