On May 16, 2024, Illinois Senator Laura Fine introduced SB3930, a significant legislative proposal aimed at establishing comprehensive protections for carbon dioxide transport and storage within the state. Dubbed the Carbon Dioxide Transport and Storage Protections Act, this bill seeks to clarify ownership rights over pore space—subsurface areas used for carbon sequestration—while addressing environmental and safety concerns associated with carbon storage.

At the heart of SB3930 is the assertion that title to pore space belongs to the surface owner of the land above it. This provision ensures that when landowners sell their property, they also retain rights to the pore space beneath, preventing the separation of these rights. The bill explicitly prohibits the amalgamation of pore space under the Eminent Domain Act, which has been a contentious issue among landowners and environmental advocates. By requiring that any carbon sequestration activities be conducted with the consent of surface owners, the legislation aims to protect property rights while promoting responsible environmental practices.

The bill also mandates the Illinois Emergency Management Agency and the Office of Homeland Security to establish a fee structure for carbon sequestration, creating the Carbon Transportation and Sequestration Readiness Fund to support these initiatives. Additionally, it requires training for relevant agencies to ensure preparedness for potential risks associated with carbon storage.

While the bill has garnered support from environmental groups advocating for clearer regulations on carbon sequestration, it has faced opposition from some industry stakeholders who argue that the restrictions could hinder the development of carbon capture technologies essential for combating climate change. Critics express concerns that the bill may complicate the regulatory landscape, potentially stalling progress in carbon management efforts.

The implications of SB3930 extend beyond legal definitions; they touch on broader economic and environmental goals. By establishing a clear framework for carbon sequestration, Illinois positions itself as a leader in climate action, potentially attracting investment in green technologies. However, the balance between environmental protection and economic development remains a critical point of debate.

As the legislative process unfolds, stakeholders will be closely watching how SB3930 evolves, particularly regarding amendments that may address concerns from both proponents and opponents. The outcome of this bill could significantly influence Illinois' approach to carbon management and its commitment to reducing greenhouse gas emissions in the coming years.
