Carbon dioxide pipeline regulation is expected to be a central issue in Iowa’s 2026 legislative session, with at least one senior Republican lawmaker warning that progress on other policy priorities may stall unless the issue is addressed.
State Representative David Sieck, who represents Mills and Fremont counties and part of Pottawattamie County, said the long-running debate over carbon capture pipelines has reached a critical point. Speaking ahead of the session, which begins on January 12, Sieck identified carbon pipeline legislation as his top priority for lawmakers.
According to Sieck, the issue has resurfaced repeatedly in recent years without resolution, contributing to growing tensions within the Republican-led legislature. He suggested that failure to pass some form of pipeline legislation could impede broader legislative productivity in 2026.
A Divisive Issue Within the GOP
Proposed carbon capture pipelines, intended to transport CO2 from ethanol plants to underground storage sites, have divided lawmakers along ideological and regional lines.
Supporters argue the projects could strengthen Iowa’s agricultural and biofuels economy by helping ethanol producers lower their carbon intensity and remain competitive in low-carbon fuel markets.
Opponents, however, have raised concerns about pipeline safety and the use of eminent domain to secure land access from unwilling property owners. These issues have proven especially contentious in rural districts, where landowner opposition remains strong.

Beyond carbon pipelines, Sieck identified property tax reform as another major issue likely to feature prominently in the upcoming session. He acknowledged that reform efforts have historically struggled in Iowa, citing the complexity of existing tax laws, but said constituents continue to push for action.
Workforce development rounds out Sieck’s top three priorities, with a focus on job training initiatives and policies aimed at retaining and attracting skilled workers to the state.
With divisions over carbon pipelines unresolved, lawmakers face pressure to find compromise as the 2026 session approaches.
