Arm reports rising absolute emissions across two consecutive years despite operational cuts, driven by expansion into production silicon. Supply-chain emissions are unassured and jumped 38% in FYE26. The company has no SBTi-validated target, excludes downstream product emissions, and lacks circular-economy and water-reduction frameworks.
