Senate Bill 364, introduced in Indiana on January 30, 2025, aims to regulate atmospheric interventions by prohibiting individuals from discharging chemicals or apparatuses into the atmosphere with the intent to alter sunlight, temperature, or weather conditions. This legislation is a response to growing concerns about geoengineering practices and their potential environmental impacts.

The bill outlines specific exceptions under which such discharges may be permitted, although these conditions have not been detailed in the initial text. Violators of this law would face a Class A misdemeanor, signaling the state's serious stance on unauthorized atmospheric manipulation.

The introduction of Senate Bill 364 has sparked discussions among lawmakers and environmental advocates. Proponents argue that the bill is necessary to protect the environment from unregulated geoengineering activities that could have unforeseen consequences. Critics, however, express concerns about the potential overreach of the law, fearing it may hinder legitimate scientific research aimed at addressing climate change.

As the bill moves to the Committee on Corrections and Criminal Law, its implications could extend beyond environmental protection. Experts suggest that if passed, it may set a precedent for how states regulate climate intervention technologies, influencing future legislation across the country.

The bill is set to take effect on July 1, 2025, if it passes through the legislative process. As discussions continue, stakeholders are closely monitoring the developments surrounding this significant piece of legislation.
