Sustainable Fab Support — Energy, Water, Waste, and Emissions Beyond Greenhouse Gases
Semiconductor sustainability is often introduced through greenhouse gas (GHG) reduction, particularly high-GWP process gases, as these emissions are measurable and directly linked to climate change. However, the true impact extends beyond direct emissions to include energy consumption, carbon intensity of utilities, materials, and the growing demand from digital infrastructure.
Fabs also operate under broader constraints such as air quality, water availability, waste management, safety, cost, and regulatory requirements. Environmental impacts therefore span both global and local levels, from long-term GHG effects to immediate challenges like air pollutants and wastewater.
Addressing these complexities requires a system-level approach, where tools, utilities, and lifecycle factors are interconnected, and optimizing one area may shift impacts elsewhere. With rising pressures from AI growth and stakeholder expectations, it is clear that GHG reduction alone is not sufficient. Sustainable semiconductor manufacturing depends on integrated management across energy, water, waste, emissions, reliability, and cost.
