Geoengineering Oversight

Geoengineering oversight frameworks aim to prevent unilateral experiments that could alter planetary systems. They propose moratoria, licensing regimes, and transparency registries for solar radiation management, marine cloud brightening, and stratospheric aerosol injection. Key components include global notification requirements, consent processes involving affected regions (especially the Global South), and independent scientific panels that vet risk assessments before trials commence. Remote sensing networks and atmospheric models would monitor experiments in real time to enforce compliance.

Multilateral bodies such as the UN Environment Assembly, Convention on Biological Diversity, and emerging coalitions of small island states are drafting codes of conduct, while philanthropies fund governance research and community consultation. Insurance and liability mechanisms are under discussion to address transboundary harm, and export controls on precursor chemicals or hardware could prevent rogue actors from scaling interventions covertly.

This governance layer is TRL 3—largely conceptual—but pressure is rising as private companies and universities announce field tests. Establishing binding oversight before deployment is critical to avoid geopolitical conflict and ensure any last-resort interventions align with justice principles and long-term monitoring obligations.
