A two-man climate startup is under federal investigation for geoengineering the atmosphere by releasing sulfur dioxide—an EPA-regulated air pollutant—into the stratosphere under the guise of climate cooling.
The company, Make Sunsets, was founded by two Silicon Valley entrepreneurs with no background in atmospheric science.
Their business model?
Fill weather balloons with sulfur dioxide and hydrogen gas, launch them over 66,000 feet into the sky, and sell “cooling credits” to customers based on how much estimated warming each balloon release negates.
Now, they’re facing consequences—granted, these balloons release infinitesimally less sulfur into the sky than airplanes do.
On Tuesday, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced that his agency is investigating the company’s actions under the Clean Air Act, citing potential air quality violations.
