GES 2025 Tokyo

Building on the foundational work of the SEMI Sustainability Climate Consortium and the 2025 Global Climate Summit Workshops (GCSW), this closed-door summit is designed to shift our industry from alignment to action. We are convening a select group of key Executive decision makers & senior leaders from fabs, fabless companies, hyperscalers, and key suppliers and energy partners to: 

  • Showcase and accelerate progress on priority climate initiatives: Abatement, Gas Substitution, Green Materials, and Energy
  • Define clear deliverables and next-phase commitments that unlock scale and momentum
  • Strengthen executive collaboration to remove barriers, share ownership, and drive measurable results

This Summit is not about what we could do — it’s about what we will do, and who will lead.

Click here for the Executive Briefing outlining the event objectives, and the action pathways and methods of engagement for all attendees.  Plan ahead on how presence can shape outcomes that accelerate our industry's decarbonization.

Priority Initiative: Gas Substitution

Opening Remarks

Current efforts to pursue low Global Warming Potential (GWP) gas substitutions in etch and chamber clean applications remain fragmented, resulting in high material costs for HVM application. While promising gas substitutions exist, the traditional paths of small scale or single customer adoption are typically too expensive due to cost scaling limitations. So how do we enable low GWP gas substitutions that also meet cost (as well as performance) expectations? By coordinating a fab-led, industry wide approach to
1) Prioritize a single, low GWP target gas for replacement
2) Co-create and execute a phased experimental plan
