Resumen con IA Public airports must start sending monthly reports to the Department of Transportation about any aircraft used to intentionally change the weather or sunlight. It is illegal for anyone to release substances into the air to affect the climate, and people who do this could face felony charges or large fines. If an airport fails to follow these new reporting rules, it will not be able to receive state funding. (Todavía no está traducido al español.)1

This bill relates to the intentional emission of air contaminants into the atmosphere, including prohibitions and reporting requirements. The bill requires entities that operate an airport open to public use to submit monthly reports to the department of transportation (department) beginning October 1, 2026. The reports must include information regarding the physical presence of aircraft equipped with components that may be used to intentionally emit, inject, release, or disperse air contaminants into the atmosphere for the express purpose of affecting temperature, weather, climate, or the intensity of sunlight, as well as information regarding the landing, takeoff, stopover, or refueling of such aircraft at the airport. The bill provides that, notwithstanding any other provision of law to the contrary, a project or program located on or in support of an airport open to public use that is not in compliance with the reporting requirements is ineligible to receive state funding until compliance is achieved. The bill requires the department, upon receipt of the required reports, to submit aggregated reports to the department of natural resources and the applicable state law enforcement agencies that support enforcement of weather engineering prohibitions. The bill also requires the department to incorporate the reporting guidelines into grant agreements for airports open to public use that receive state funding and authorizes the department to adopt rules implementing the reporting requirements. The bill provides that the emission, injection, release, or dispersion of a chemical, chemical compound, substance, or apparatus into the atmosphere within the borders of the state for the express purpose of affecting temperature, weather, climate, or the intensity of sunlight, or any other purpose not presently regulated by state or federal law, is prohibited. The bill provides that any person who violates the prohibition is guilty of a class “D” felony and, for a corporation that violates the prohibition, an additional civil penalty up to $100,000 is imposed on the corporation’s officers, directors, or employees. A class “D” felony is punishable by confinement for no more than five years and a fine of at least $1,025 but not more than $10,245. Each day a violation occurs constitutes a separate offense.

Nota fiscal
Resumen con IA This bill prohibits the intentional release of substances into the atmosphere to affect weather or climate and requires public airports to submit monthly reports to the Department of Transportation. The fiscal impact cannot be determined because the number of new convictions cannot be estimated. The average state cost per Class D felony conviction is between $13,000 and $18,100, which would affect the General Fund through costs for the Judicial Branch, the Indigent Defense Fund, and the Department of Corrections.

Description
House File 2640 requires entities that operate an airport open to public use to submit monthly reports to the Department of Transportation (DOT) beginning October 1, 2026. The reports must include information regarding the physical presence of aircraft equipped with components that may be used to intentionally emit, inject, release, or disperse air contaminants into the atmosphere for the express purpose of affecting temperature, weather, climate, or the intensity of sunlight, as well as information regarding the landing, takeoff, stopover, or refueling of such aircraft at the airport. Any airport out of compliance with the reporting requirements is ineligible to receive State funding until compliance is achieved.
The Bill requires the DOT to submit aggregated reports to the Department of Natural Resources (DNR) and the State law enforcement agencies that support enforcement of weather engineering prohibitions. The Bill requires the DOT to adopt administrative rules implementing the reporting requirements.
The Bill prohibits the emission, injection, release, or dispersion of a chemical, substance, or apparatus into the atmosphere within the State for the express purpose of affecting temperature, weather, climate, or the intensity of sunlight, or any other purpose not presently regulated by State or federal law. Under the Bill, any person who violates the prohibition is guilty of a Class D felony. The Bill imposes an additional civil penalty of up to $100,000 on the corporations that engage in weather engineering. Each day a violation occurs constitutes a separate offense.
Background
A Class D felony is punishable by confinement for no more than five years and a fine of at least $1,025 but not more than $10,245.
Assumptions
- The following will not change over the projection period: charge, conviction, and sentencing patterns and trends; prisoner length of stay (LOS); revocation rates; plea bargaining; and other criminal justice system policies and practices.
- County jail data is unavailable. For purposes of this analysis, the marginal cost for county jails is assumed to be $50 per day.
- Conviction data reflects the total number of convictions in adult court, which may include multiple convictions per individual. Not all convictions lead to incarceration, and there may be a delay between conviction and prison admission, which can contribute to differences in totals.
- A six-month delay is assumed from the effective date of the Bill to the date the first offender will enter the correctional system.
- Offender-based convictions are a count of individuals convicted of the same offense. Each offender is counted only once per Iowa Code section, regardless of the number of individual convictions.
- Admissions are a count of individuals newly admitted to the Department of Corrections (DOC) for supervision during a selected time period, based on the most serious offense committed.
Correctional Impact
House File 2640 creates a new offense classified as a Class D felony. The correctional impact of the Bill cannot be determined because the number of new convictions cannot be estimated. Figure 1 shows estimates for sentencing to State prison, parole, probation, or Community-Based Corrections (CBC) residential facilities; LOS in months under those supervisions; and supervision marginal costs per day for a Class D felony. Refer to the Legislative Services Agency (LSA) memo addressed to the General Assembly, Cost Estimates Used for Correctional Impact Statements, dated January 12, 2026, for information related to the correctional system.

Minority Impact
The minority impact cannot be determined since the number of new convictions under the Bill is unknown. Refer to the LSA memo addressed to the General Assembly, Minority Impact Statements, dated January 12, 2026, for information related to minorities in the criminal justice system.
Fiscal Impact
The fiscal impact cannot be determined because the number of new convictions under the Bill cannot be estimated. The average State cost per Class D felony is between $13,000 and $18,100. The estimated impact to the General Fund includes operating costs incurred by the Judicial Branch, the Indigent Defense Fund, and the DOC. The costs would be incurred across multiple fiscal years for prison and parole supervision.
