The World’s Most Polluted Countries

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

The World’s Most Polluted Countries

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 Newsexplained. 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. Bloombergreported 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, Reutersreported 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.

    A new study suggests using virtual reality to depict worst-case environmental scenarios like mass coral bleaching events can help motivate people to support climate policies.

    AM Briefing: Hurricane Erick’s Rapid Intensification

    On storm damage, the Strait of Hormuz, and Volkswagen’s robotaxi

    Hurricane Erick Intensified Really, Really Quickly

    Current conditions: A dangerous heat dome is forming over central states today and will move progressively eastward over the next week • Wildfire warnings have been issued in London • Typhoon Wutip brought the worst flooding in a century to China’s southern province of Guangdong.

    THE TOP FIVE

    1. Hurricane Erick slams into Mexico after rapid intensification

    Hurricane Erick made landfall as a Category 3 storm on Mexico’s Pacific coast yesterday with maximum sustained winds around 125 mph. Damages are reported in Oaxaca and Guerrero. The storm is dissipating now, but it could drop up to 6 inches of rain in some parts of Mexico and trigger life-threatening flooding and mudslides, according to the National Hurricane Center. Erick is the earliest major hurricane to make landfall on Mexico's Pacific coast, and one of the fastest-intensifying storms on record: It strengthen from a tropical storm to a Category 4 storm in just 24 hours, a pattern of rapid intensification that is becoming more common as the Earth warms due to human-caused climate change. As meteorologist and hurricane expert Michael Lowry noted, Mexico’s Pacific coast was “previously unfamiliar with strong hurricanes” but has been battered by epic storms over the last two years. Acapulco is still recovering from Category 5 Hurricane Otis, which struck in late 2023.

    It’s Chris Wright’s Worldview. They’re Just Legislating It.

    The energy secretary's philosophy is all over the Senate mega-bill.

    As the Senate Finance Committee worked on its version of the reconciliation bill that would, among things, overhaul the Inflation Reduction Act, there was much speculation among observers that there could be a carve out for sources of power like geothermal, hydropower, and nuclear, which provide steady generation and tend to be more popular among Republicans, along the lines of the slightly better treatment received by advanced nuclear in the House bill.

    Instead, the Senate Finance Committee’s text didn’t carve out these “firm” sources of power, it carved out solar and wind, preserving tax credits for everything else through 2035, while sunsetting solar and wind by 2028.

    When I reached out to climate tech investors on Tuesday to gauge their reaction to the Senate’s proposed overhaul of the clean energy tax credits, I thought I might get a standard dose of can-do investor optimism. Though the proposal from the Senate Finance committee would cut tax credits for wind and solar, it would preserve them for other sources of clean energy, such as geothermal, nuclear, and batteries — areas of significant focus and investment for many climate-focused venture firms.

    But the vibe ended up being fairly divided. While many investors expressed cautious optimism about what this latest text could mean for their particular portfolio companies, others worried that by slashing incentives for solar and wind, the bill’s implications for the energy transition at large would be categorically terrible.
