Rio Tinto's London-listed shares closed at GBp 7,088.00 on September 25, 2026, up 0.25% from the prior session. The stock move itself is minor, but the same week brought a more significant development for investors tracking industrial decarbonization: Rio Tinto and Shougang Group commissioned a carbon capture trial facility at Shougang's blast furnace operations in China. The facility can process up to 3,000 cubic meters of blast furnace gas per hour and capture up to 10,000 tonnes of CO2 annually. It stems from a 2022 memorandum of understanding focused on low-carbon ironmaking and carbon capture utilization. Rio Tinto provided technical support, while Shougang will run it long-term for research. For anyone watching steel decarbonization, this is a concrete pilot worth monitoring, even if the capacity is small relative to a full-scale plant. Rio Tinto also signed a project agreement with the Nyangumarta Warrarn Aboriginal Corporation for its proposed Winu copper-gold mine, but that remains subject to approvals and a final investment decision. The carbon capture trial is the more immediately relevant item for climate-focused investors.
