MKS Inc. Announces SBTi Approval of Science-Based Emissions Reduction Targets

ANDOVER, Mass., March 12, 2026 (GLOBE NEWSWIRE) -- MKS Inc. (NASDAQ: MKSI), a global provider of enabling technologies that transform our world, today announced that its near-term science-based emissions reduction targets have been approved by the Science Based Targets initiative (SBTi).

MKS has committed to reduce absolute Scope 1 and 2 greenhouse gas emissions 42% by 2030, from a 2022 baseline year. The Company also has committed that 69% of its suppliers and customers by emissions covering purchased goods and services and use of sold products, will have science-based targets by 2030. The SBTi has independently assessed these targets and verified that they align with the 1.5°C Business Ambition trajectory, as recommended by the latest climate science.

"As a critical technology partner, we recognize the importance of reducing emissions across our value chain," said John T.C. Lee, President and Chief Executive Officer of MKS. "The science-based targets approved by the SBTi provide a critical framework for accountability and progress, and we are dedicated to meeting these goals as part of our broader contribution to global decarbonization."

The approved targets expand upon MKS' initial commitment to reduce Scope 1 and 2 emissions, first announced in December 2023. Since then, the Company has recalculated its Scope 1 and Scope 2 emissions inventory to reflect a broader portion of its operations and has also expanded its calculation of Scope 3 categories relevant to MKS in line with SBTi criteria. These updates ensure that MKS' emissions inventory reflects a more complete and accurate view of its operational and value-chain footprint.

MKS reports on progress toward its climate goals in its annual Environmental, Social and Governance (ESG) Report.
