AN ACT TO DECLARE CERTAIN LEGISLATIVE FINDINGS RELATING TO GEOENGINEERING; TO AMEND SECTION 49-17-5, MISSISSIPPI CODE OF 1972, TO DEFINE THE TERM "GEOENGINEERING" WITHIN THE MISSISSIPPI AIR AND WATER POLLUTION CONTROL LAW; TO AMEND SECTION 49-17-17, MISSISSIPPI CODE OF 1972, TO GIVE THE MISSISSIPPI AIR AND WATER POLLUTION CONTROL COMMISSION AUTHORITY TO ISSUE, MODIFY OR REVOKE ORDERS RELATED TO GEOENGINEERING; TO AMEND SECTION 49-17-19, MISSISSIPPI CODE OF 1972, TO PROHIBIT GEOENGINEERING IN MISSISSIPPI AND TO CREATE PENALTIES FOR VIOLATIONS; AND FOR RELATED PURPOSES.

Impact

The enactment of SB2666 is set to enhance Mississippi's commitment to environmental protection by explicitly banning geoengineering practices. Geoengineering, which often involves the large-scale manipulation of environmental processes to combat climate change, is deemed hazardous by the bill’s supporters due to the lack of understanding of its long-term effects. As such, the legislation empowers the state commission to impose strict penalties on individuals or entities engaging in such activities, labeling it a felony with substantial fines and potential imprisonment.

Summary

Senate Bill 2666 seeks to regulate geoengineering activities within the state of Mississippi by declaring certain legislative findings and amending existing pollution control laws. The bill aims to define geoengineering, grant the Mississippi Air and Water Pollution Control Commission the authority to issue orders related to these activities, and ultimately prohibits geoengineering practices altogether. It reflects concerns regarding the unknown risks associated with geoengineering, particularly regarding its potential impact on public health and environmental welfare.

Contention

While the bill has garnered support among various stakeholders advocating for public health and environmental integrity, it could spark debates about the limits of state control over scientific exploration. Critics may express concern regarding the blanket prohibition of geoengineering, arguing that this could hinder innovative environmental solutions that could address climate challenges. The legislation may also impact potential federal collaborations regarding climate intervention strategies, as it presents a conflict of interest with ongoing research in the field.
