Chemours has published its 2025 Sustainability Report, reporting reductions in greenhouse gas and fluorinated organic chemical (FOC) emissions while expanding the role of low-global-warming-potential (GWP) refrigerants and liquid cooling technologies in its sustainability strategy. The company reported an 80% reduction in air and water FOC process emissions and a 57% reduction in Scope 1 and 2 greenhouse gas emissions since 2018.
Chemours said its absolute Scope 3 greenhouse gas emissions declined 30% from the 2018 baseline, due in large part to increased adoption of Opteon™ low-GWP refrigerants. In 2025, Opteon™ sales helped avoid more than 80 million metric tons of CO2e emissions by replacing high-GWP refrigerants, while the company’s low-GWP products had delivered more than 350 million tons of avoided global CO2e emissions by year-end 2025.
For data centers, Chemours highlighted two-phase direct-to-chip (DTC) and two-phase immersion cooling. According to the report, two-phase DTC cooling can reduce cooling energy consumption by 25% to 35% compared with traditional air-cooled systems and achieve near-zero water use through closed-loop, non-evaporative operation. Third-party testing of R-515B delivered heat fluxes exceeding 500 W/cm² (approx. 3,226 W/in²).
Chemours also reported that its two-phase immersion cooling technology can lower energy consumption by up to 40%, reduce cooling energy use by up to 90% and nearly eliminate cooling-related water use. Samsung Electronics qualified Chemours’ two-phase immersion cooling fluid with its generation four Solid State Drive, while a separate 12-month test conducted with NTT DATA and Hibiya Engineering found no signs of fluid or equipment degradation.
“Our sustainability strategy is delivering tangible results while creating long-term value for the company and its stakeholders,” said Kathy O’Keefe, Chemours Chief Sustainability Officer. “The progress reflected in this year’s report demonstrates how responsible manufacturing, operational excellence, and innovation can work together to reduce our environmental footprint, strengthen our business, and help our customers meet their own sustainability goals.”
