Stardust Raises $60M in Venture Round for Solar Geoengineering Technology

Why It Matters

If private capital drives solar geoengineering, profit motives could bias research, accelerate deployment of untested materials, and erode public confidence, potentially shaping climate policy without adequate scientific scrutiny. Ensuring the technology is developed through transparent, publicly coordinated efforts is critical to managing its environmental and geopolitical risks.

Deal Summary

Stardust, an American‑Israeli solar geoengineering startup, announced a $60 million venture‑capital raise, the largest known round for a company in this sector. The funding will support development of its proprietary particle‑based cooling system slated for deployment by the early 2030s.
