The rapid advancement of geoengineering technologies has sparked intense debate regarding their regulatory oversight. While some scholars propose utilizing established environmental frameworks, such as the London Protocol, I argue that these mechanisms are fundamentally inadequate for addressing the distinct complexities of climate intervention research.
Existing treaties were primarily designed to regulate industrial pollutants rather than intentional climate manipulation. The London Protocol, for instance, focuses on dumping waste at sea, which provides a narrow scope that fails to encompass the atmospheric or land-based experiments central to solar radiation management. Because these frameworks lack the specific technical protocols required to assess the long-term ecological consequences of geoengineering, attempting to force them into this role creates a dangerous regulatory vacuum that could lead to irreversible environmental damage.
Furthermore, the geopolitical implications of geoengineering demand an entirely new international agreement. Climate modification experiments could potentially alter weather patterns across national borders, triggering diplomatic conflicts that current environmental conventions are not equipped to mediate. For example, a state deploying stratospheric aerosol injection might inadvertently cause droughts in a neighbouring country, necessitating a robust, transparent legal framework that includes equitable decision-making processes and liability standards. Existing conventions lack the mechanisms to handle such transboundary disputes or to ensure global consensus on high-risk research activities.
In conclusion, existing environmental treaties offer an incomplete solution for governing geoengineering. Given the unprecedented scope and potential for cross-border friction, a specialized international agreement is essential. Developing a dedicated regulatory structure will ensure that research is conducted with global accountability, transparency, and scientific rigour, thereby minimizing the risks associated with humanity’s intervention in the climate system.
