According to Wikipedia, Solar geoengineering, or solar radiation modification, is a type of climate engineering in which sunlight (solar radiation) would be reflected back to outer space to limit or reverse human-caused climate change.

An independent initiative calls for an International Non-Use Agreement regarding solar geoengineering. The initiators' view is that solar geoengineering is currently not desirable due to associated risks.

This question asks a simpler and less strict question than its companion; whether there will be any pact against solar geoengineering, even if it doesn't meet the full 5 core commitments and measures of the proposed Agreement.
