The document outlines the increasing likelihood of exceeding the 1.5°C warming threshold and the resulting interest in 'emergency' options like solar radiation modification (SRM) and carbon dioxide removal (CDR). It highlights a critical lack of formal international and national governance for SRM, noting a specific instance in Mexico where a private US company conducted unauthorized aerosol experiments. The text details efforts by IAI, CEPAL, and C2G to raise awareness and build regional governance frameworks in Latin America and the Caribbean to manage these climate interventions.

• Current global policies and commitments are insufficient to meet the Paris Agreement goals; policies in place are projected to lead to 2.8°C of warming this century, while the implementation of unconditional and conditional Nationally Determined Contributions (NDCs) would only reduce this to 2.6°C and 2.4°C, respectively.
• To limit warming to 1.5°C by 2100 following a temporary overshoot, the world will require the large-scale deployment of carbon dioxide removal (CDR) to achieve net removal of CO2 from the atmosphere in the latter half of the century.
• There is a significant lack of formal and robust governance for solar radiation modification (SRM). While various international treaties—such as the Convention on Biological Diversity and the Vienna Convention for the Protection of the Ozone Layer—contain applicable provisions, none cover the topic comprehensively.
• In January 2023, the Mexican government announced its intention to ban solar geoengineering experimentation and large-scale deployment within its territory. This followed an unauthorized small-scale commercial intervention involving aerosol balloons by the US startup "Make Sunsets" in Baja California Sur.
