As more individuals and organizations start to engage in and learn about solar geoengineering (also known as solar radiation modification – SRM), it is challenging to know where to start. A collaborative effort between The Alliance for Just Deliberation on Solar Geoengineering and the Forum on Climate Engineering Assessment aims to provide a landscape assessment of the SRM field across different sectors, institutions, and geographies. This report provides an overview of who is in the space, what they have done, and what might come next.

We hope this can provide a useful foundation for understanding where the SRM ecosystem is for anyone new to the field as well as those trying to understand how it has evolved. We plan to update this report periodically.
