Senate Bill 457, introduced in Indiana on March 21, 2025, aims to regulate carbon sequestration projects within the state, establishing a framework for the underground storage of carbon dioxide. The bill seeks to address environmental concerns related to climate change by promoting carbon capture and storage technologies while ensuring the rights of landowners are respected.

Key provisions of the bill include requirements for storage operators to obtain a UIC Class VI permit, which is necessary for the injection of carbon dioxide into underground storage facilities. The bill mandates that operators must demonstrate a good faith effort to secure consent from all pore space owners above the proposed storage site, with a requirement to obtain consent from at least 70% of these owners. Additionally, it stipulates that any pore space owners who do not agree to the integration of their interests must be equitably compensated.

The legislation has sparked notable debates among stakeholders, particularly regarding landowner rights and environmental safety. Proponents argue that the bill is essential for advancing Indiana's climate goals and attracting investment in clean energy technologies. However, opponents express concerns about the potential for coercive practices in securing landowner consent and the adequacy of environmental protections.

The economic implications of Senate Bill 457 could be significant, as it may facilitate the development of carbon capture projects that could create jobs and stimulate investment in the state. Socially, the bill raises questions about the balance between environmental initiatives and property rights, which could lead to further discussions and potential amendments as it moves through the legislative process.

As the bill progresses, its impact on Indiana's energy landscape and environmental policy will be closely monitored, with experts suggesting that successful implementation could position the state as a leader in carbon management solutions. The next steps will involve further legislative review and potential adjustments based on stakeholder feedback.
