Dear friends and colleagues, I hope you are doing well. Until now, the conversation about Sunlight Reflection Technology (SRT)* has focused on whether it should be researched at all. We think the question should shift. With climate risk accelerating and more people and communities impacted every year, the question governments need answered is a different one: what would a safe, responsible SRT option actually look like? We’re excited to let you know that this week we published two documents that propose concrete answers – and that we're putting forward for dialogue, input, and improvement. Over the coming months, we’ll be publishing our scientific work with our academic collaborators, disclosing our particle composition and other core technologies, and continuing to open our work to independent validation and for people to hold up to the requirements we’ve laid out and determine if we meet them. First, we published a new white paper: “A Proposal for the Safety and Controllability Requirements that SRM Systems Should Meet <https://www.stardustsolutions.com/science>” that outlines proposed safety and controllability requirements that guide our work. This is an initial answer to the 'what' question – what it will take for an SRT system to be safe and controlled. These are concrete, specific requirements we derived from first principles, and we invite input and discussion from the scientific community on each of them. Second, we are releasing our updated “Guiding Principles for Stardust’s Solar Radiation Modification Research <https://www.stardustsolutions.com/guiding-principles>” that answer the ‘how’ question – how this work should be conducted ethically and responsibly. These requirements span three domains: human and environmental safety, atmospheric chemistry and composition, and the climate system. They were developed in collaboration with leading governance, legal, and ethical experts, and they draw on widely accepted international frameworks. And we're publishing them so the public and the scientific community can hold us accountable to them. We’re releasing our updated Guiding Principles and technical requirements paper together because we believe the technical and ethical dimensions of this work can’t be separated. It’s not enough to build safe technology if you don’t have governance to match, and we’re committed to both. We will continue to keep you updated on our progress. In the meantime, check out our updated website: www.stardust-initiative.com All the best, The Stardust Team **SRT is also referred to as Solar Radiation Modification (SRM) * -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
