Supporting an informed, evidence-based discussion of sunlight reflection methods (SRM).
Introducing SRM360
SRM360 is a non-profit knowledge hub which explores the science and evidence behind sunlight reflection methods, or solar radiation modification (SRM). We work with experts and advisors from around the world to provide clear and engaging information through articles, graphics, videos, and podcasts.

Stratospheric Aerosol Injection
Stratospheric Aerosol Injection – or SAI – is an idea to create a thin, persistent layer of tiny particles in the upper atmosphere to reflect sunlight and cool the planet. How could it work and why is it being studied?
What Is SRM? Who Is Studying It, and Why?
Hear from SRM researchers around the world about why they got into this field.
Marine Cloud Brightening
Marine Cloud Brightening – or MCB – is an idea to brighten clouds over the ocean to reflect more sunlight back to space. How could it work and why is it being studied?
Mitigation Displacement: Could SRM Undermine Emissions Cuts?
A common objection to the study and potential development of sunlight reflection methods, also known as solar radiation modification (SRM), is that it could undermine efforts to cut greenhouse gas emissions – the root cause of global warming. How serious is this risk, and could it be prevented with smart policy?
Governance Recommendations for the For-profit SAI Startup “Stardust”
Janos Pasztor presents the governance recommendations he prepared for the for-profit startup “Stardust”, which is looking to develop key technology for the deployment of stratospheric aerosol injection (SAI).
Every Tonne of CO2 Adds to Global Warming
Every tonne of carbon dioxide (CO2) emitted drives up temperatures and does so almost linearly: if twice as much is emitted, the planet will warm roughly twice as much. This simple rule of thumb is the scientific foundation of today’s climate policy, but could sunlight reflection methods or solar radiation modification (SRM) undermine it?
