Carbon capture commenced - Oil and gas major ExxonMobil said on Monday it began commercial operations of a carbon capture and storage (CCS) project with ammonia producer CF Industries in Louisiana in 2025, with the project expected to transport and store up to 2 MtCO2/year from CF’s Donaldsonville complex.

A heads up - Washington's Department of Ecology (ECY) announced Tuesday it is planning to share materials and draft language related to centralised electricity markets and electricity imports during the first week of February, and is encouraging interested parties to provide comment and input. Feedback received will help informing ongoing rulemaking to facilitate linkage with the California-Quebec ETS.

Carbon tariff study slips in - The US Congress has incorporated language from the bipartisan “Providing Reliable, Objective, Verifiable Emissions Intensity and Transparency (PROVE IT) Act” into report text accompanying a fiscal 2026 spending minibus signed into law last week, directing the US DOE to study and compare the carbon intensity of US-made goods with those produced abroad, E&E News reported. The measure, backed by Senators Kevin Cramer (R-ND), John Curtis (R-UT), and Chris Coons (D-DE), had previously stalled amid conservative concerns it could lead to carbon taxes. Appropriators said the study is intended to provide US-generated data as the EU CBAM officially enters into force. While bill reports are not legally binding, agencies typically follow them, and the DOE-led study would be due by January.
