Pipeline pressure – Summit Carbon Solutions’ (SCS) supporters and opponents have urged Iowa regulators to act on the developer’s revised CO2 pipeline proposal, with industry groups requesting a hearing on Tuesday while some landowners called for the plan to be denied over eminent domain concerns, local media reported this week.

Summit unveiled the revised route on May 13, before affected landowners formally filed requests with the IUC on May 20 seeking denial of the updated proposal.

Integration - Carbon infrastructure provider Xpansiv and environmental commodities exchange Enechain have begun real-time data integration between their platforms. This will allow users of Enechain's carbon marketplace, Japan Climate Exchange (JCEX), to view bids and place trades for environmental products directly on the JCEX screen without separate registration. The move also enables centralised management of domestic and global credits, expands liquidity, and improves price discovery. The firms had earlier struck a deal to link JCEX with Xpansiv’s infrastructure, giving Japanese companies access to high-quality voluntary credits, including CCP-aligned, CORSIA-eligible, and I-RECs.
