An American-Israeli geoengineering startup seeking U.S. government contracts to cool the planet has quietly begun lobbying on Capitol Hill.
Stardust Solutions hired the the law firm Holland & Knight in the first quarter of 2025, but the firm didn’t disclose its lobbying “due to a clerical error,” Holland & Knight spokesperson Olivia Hoch said. Stardust’s lobbying efforts have not been previously reported.
Hoch declined to say how much Stardust had paid the firm or the specific issues it had lobbied on. That information would be disclosed in “the required forms in the coming days,” she said in an email.
Stardust is developing an integrated system to produce reflective particles, distribute them in the stratosphere and monitor their effectiveness. The startup and its investors are hoping the U.S. or a coalition of other governments will eventually decide to pay for the use of its technology.
