Iowa

A bill for an act relating to the intentional emission of air contaminants into the atmosphere.(See HF 927.)

A bill for an act relating to the intentional emission of air contaminants into the atmosphere, including prohibitions and reporting requirements, and providing penalties.(See HF 2640.)

Iowa's HF2173 goes beyond a simple geoengineering ban by establishing a statewide airport surveillance network requiring monthly reports on aircraft equipped for atmospheric dispersal, with felony penalties for violations and personal liability for corporate officers up to $100,000.

A bill for an act prohibiting the intentional emission of air contaminants into the atmosphere, and providing penalties. (Formerly HF 2173.)

Iowa's bill takes a pure criminal-law approach to geoengineering prohibition, placing it in the criminal code as a class D felony with per-day offence stacking. An amendment stripped the bill's original airport surveillance apparatus while adding a carve-out for agricultural aerial applicators.

Iowa establishes a geoengineering prohibition through a regulatory framework rather than direct criminal penalties, delegating implementation details entirely to the Environmental Protection Commission's emergency rulemaking authority.

A bill for an act relating to the prohibition of geoengineering activities, providing penalties, and including effective date provisions.

Iowa's approach combines expansive definitions covering electromagnetic fields, sound pollution, and radiation with Class D felony penalties, cease-and-desist authority for the Department of Public Safety, and provisions explicitly challenging federal authority by empowering state officials to order the cessation of federal programs.

Iowa's bill takes the unusual approach of making Department of Public Safety cease-and-desist orders carry immediate court-order weight based solely on suspicion, while defining prohibited atmospheric activities broadly enough to include electromagnetic fields, sound waves, and light pollution when weather manipulation is intended.
