The UK has targets to deploy >100MtCO2 of carbon dioxide removal (CDR) by 2050, with interim technical targets of 5 MtCO2 and 23 MtCO2 by 2030 and 2035, respectively. In 2019, a number of policy initiatives were announced that have kick-started a nascent UK CDR ecosystem. To build on these foundations, it is recognised that there is a need for a shift in UK CDR institutional, governance and policy development commensurate with a pathway to realise the 2035 and 2050 targets. The US has also announced a number of potentially game-changing policies that stand to generate spillovers which will reduce the cost of scaling the sector if they can be captured by the UK. The question for UK policy-makers is therefore how to capture these spill-over effects when they materialise, and how to collaborate with US market-makers to track developments so as to design timely and effective policy when they are opportune to capture from the US. This report shares the findings from three engagements with US CDR initiatives undertaken by the CO2RE Ecosystem 26+ project team in March 2025. The project sought to explore how the proposed US interventions were being operationalised, in order to analyse how they might relate to and interact with other international CDR sector initiatives – specifically those taking place in the UK and EU.
