The World’s Most Polluted Countries

On air quality, Ford’s pivot, and solar geoengineering

Current conditions: Flash floods inundated parts of northern Iraq • Fire weather watches are in effect across several states, from Iowa to Maryland • Today marks the official start of spring.

THE TOP FIVE

1. Just 7 countries met WHO pollution limits in 2023

A region’s air should contain no more than 5 micrograms per cubic meter of the dangerous pollutant known as PM2.5, according to World Health Organization recommendations. In Bangladesh last year, the average concentration was 79.9 micrograms, making it the most polluted country in the world. Pakistan, India, Tajikistan, and Burkina Faso also had alarmingly high levels of PM2.5, which comes primarily from burning fossil fuels and is linked to 4 million premature deaths every year. The findings come from Swiss company IQAir, which uses 30,000 air quality monitors to understand pollution levels across the world. “The number of countries and regions with air quality monitoring has steadily increased over the past six years,” the company said in a press release.

In 2023 just seven countries had air quality that met the WHO guidelines: Australia, Estonia, Finland, Grenada, Iceland, Mauritius, and New Zealand. Average PM2.5 concentration across the U.S. was 9.1 micrograms, and Columbus, Ohio, was the most polluted major city in America.

2. DOE expects geothermal boom by 2050

A report from the Department of Energy projects geothermal energy deployment in the U.S. will grow dramatically by 2050, so long as developers can bring down costs. The DOE says geothermal could account for up to a third of the additional clean energy the country will need by 2050 to hit President Biden’s emissions targets and meet growing electricity demand, E&E News explained. Geothermal energy harnesses the heat from beneath the Earth’s surface for around-the-clock clean energy. Innovations in drilling technology are expected to bring the price of geothermal power down from $100 per megawatt-hour to as low as $60 per megawatt-hour by 2030, which would put it roughly in line with other energy sources, the DOE said. And new geothermal sites will need to be tapped: The report said 18 states will likely have geothermal operations by 2050, up from seven now.

3. Report: Ford pivoting to small EVs

Ford is reportedly “pivoting” from big electric vehicles to smaller, cheaper EVs in an attempt to keep up with Chinese manufacturers like BYD. Bloomberg reported the company has put together a team to work on a new electric platform for its small EVs, with the first vehicle slated to arrive in 2026 and cost around $25,000. “Plans for an electric three-row SUV have been delayed,” Bloomberg added.

4. Saudi Aramco CEO says fossil fuel phase out is a ‘fantasy’

In case you were wondering how things are going at CERAWeek, the big oil and gas conference taking place in Houston this week, Reuters reported that “top oil executives took to the stage … to vocally oppose calls for a quick move away from fossil fuels.” “We should abandon the fantasy of phasing out oil and gas, and instead invest in them adequately,” said Amin Nasser, CEO of Saudi Aramco. His remarks were reportedly met with applause and echoed by leaders from Shell, Petrobras, and Exxon Mobil. Petrobras CEO Jean Paul Prates warned rushing the energy transition will create a “crisis that we will never forget.” Meg O’Neill, CEO of Woodside Energy, said the debate had become too “emotional,” and claimed the market for clean fuel technologies is some decades away. U.S. Energy Secretary Jennifer Granholm pushed back, pointing to projections showing oil and gas peaking demand by 2030, and called the transition “an undeniable, inevitable, and necessary realignment of the world’s energy system.”

5. Harvard pulls the plug on solar geoengineering experiment

Researchers at Harvard have abandoned a plan to conduct what would have been one of the first solar geoengineering experiments in the stratosphere. Solar geoengineering – also known as “solar radiation management” – involves reflecting sunlight back into space by spraying aerosols into the stratosphere in an attempt to cool temperatures on Earth. It has long been a somewhat fringe idea among scientific circles – a sort of option of last resort – but interest has grown as global emissions climb and the Earth gets hotter. While most solar geoengineering research has happened in labs, Harvard’s Stratospheric Controlled Perturbation Experiment (SCoPEx) was going to launch a high-altitude balloon to release aerosols and observe their behavior. But the project was controversial from the start and encountered multiple delays. In the end its lead investigator walked away. “The platform developed for SCoPEx is expected to be repurposed for basic scientific research in the stratosphere unrelated to solar geoengineering,” the university said in a statement.

Current conditions: A new nor’easter is washing the ocean over North Carolina’s Highway 12 right as crews complete reconstruction on the Outer Banks thoroughfare following last month’s storm • After whipping Mexico’s Pacific Coast with heavy rains, Hurricane Trudy has weakened to a Category 1 storm • Super Typhoon Champi knocked out power for more than half of Guam before barreling toward the Philippines as a potential Category 5 storm.


THE TOP FIVE

1. Wall Street’s AI rout ends for chipmakers, but not for indebted cloud computing giants

Last week was the worst week for the tech-heavy Nasdaq 100 Index since President Donald Trump’s tariffs roiled the market in April 2025. The reason? Hotter than expected federal data on inflation fueled fears of an interest rate hike that could prove devastating to the buildout of artificial intelligence infrastructure. Investors were already worrying the physical investments would cost more than giants such as ChatGPT-maker OpenAI or Claude-creator Anthropic are set to earn. But on Monday, semiconductor makers such as Oracle, Intel, and Micron Technology rallied as the AI rout came to an end. Yet CoreWeave, the cloud-computing heavyweight that led the selloff last week, closed slightly lower. The issue, investors told CNBC, is the company’s debt load. “The market tends to get worried about companies that have refinance risk when rates are higher, and CoreWeave was a little bit of the poster child,” John Lloyd, global head of multi-sector and corporate credit at Janus Henderson, whose firm owns CoreWeave bonds due in 2031, told the broadcaster. “They need the debt markets in order to grow, in some form or fashion.” That CoreWeave came close to bouncing back at all comes down at least in part to Ark Investment Management chief Cathie Wood opting to buy about $12 million of shares in the company amid the market plunge last week, a play for which The Street notes she’s known. Notably, Oracle, which was previously dubbed the “canary in the coal mine” for concern over AI debt, closed just 1% higher before plunging in after-market trading.

Exclusive: Veckta Raises $11 Million to Help Businesses Buy Onsite Solar and Storage

The company simplifies the process of getting consistent, apples-to-apples bids.

With commercial electricity prices steadily climbing, many businesses and real estate owners are increasingly eager to generate and store their own power onsite, cutting their bills and making costs more predictable. But figuring out whether solar and storage can actually pencil out — and under what conditions — can be a nightmare. Ask a handful of developers for a quote and you might get a rooftop solar array from one, a ground-mounted solar and battery system from another, and a gas turbine from a third, each with its own size, price, and financing terms.

That leaves buyers comparing apples to oranges. And for businesses evaluating a portfolio of potential projects, the process gets even messier. “These are very local-centric systems. Different interconnection requirements, different permits, different suppliers,” Gareth Evans, CEO of the onsite energy planning and procurement startup Veckta, told me. “There are hundreds of solar developers in every state.” The hard part, he added, is “knowing what supplier to go with, how to ask them the right questions in the right language, in the right format, so that you’re getting consistent bids back that you can compare and contrast.”
