Stardust Solutions, a solar geoengineering startup, has released guidelines for projects aimed at limiting global warming by reflecting sunlight away from the Earth. Emphasizing the use of safe materials, scalable systems, and precise monitoring tools, the company has outlined guiding principles as a voluntary code of conduct for their policies and activities. Stardust is currently developing a proprietary sunlight-reflecting particle and systems to spray and monitor these particles above the Earth's surface. They have stated that the technology will only be allowed for use if deemed safe and necessary by a national government to prevent extreme warming.
