Alignment with Sustainable Development Goals (SDGs)

The industry’s transition to green manufacturing is underpinned by a commitment to several key SDGs. Technological breakthroughs and strategic initiatives are directly addressing global targets for environmental stewardship and sustainable industrialization.

SDG 9 & SDG 12: Fostering Sustainable Industrial Innovation and Responsible Production

The semiconductor industry is actively upgrading its infrastructure and processes to support sustainable innovation and responsible consumption and production patterns. Key advancements include:

• Waste Reduction and Circular Economy: A shift from a linear “take-make-dispose” model to a circular one is being implemented. Initiatives include chemical recycling to recover valuable materials, silicon upcycling, and the adoption of minimalistic, eco-friendly packaging.
• Green Chemistry and Hazardous Material Reduction: In line with SDG 12.4, companies are applying green chemistry principles to eliminate hazardous substances. Advanced abatement systems are being deployed to capture and neutralize harmful emissions like perfluorocarbons (PFCs), significantly reducing industrial pollution.
• AI-Optimized Manufacturing: Artificial intelligence is being leveraged to enhance production efficiency, inspect for defects, and predict factory maintenance, thereby minimizing resource waste and supporting the goals of sustainable industrialization (SDG 9).

SDG 7 & SDG 13: Advancing Clean Energy and Climate Action

Addressing the immense energy consumption of chip fabrication is a primary focus, with efforts directly contributing to affordable, clean energy and climate action.

1. Renewable Energy Integration: Major manufacturers are transitioning to renewable energy sources. This includes signing large-scale power purchase agreements for solar and wind energy, with companies like GlobalFoundries targeting 100% carbon-neutral power. This supports SDG 7.2.
2. Energy Efficiency Enhancements: Fabs are adopting energy-efficient equipment, such as megasonic cleaning and idle-time controllers, which can reduce power consumption by up to 30%. The use of advanced materials like silicon carbide (SiC) and gallium nitride (GaN) further reduces energy loss in AI applications.
3. Greenhouse Gas (GHG) Reduction: By investing in renewable energy and advanced emission abatement technologies, the industry is taking direct action to combat climate change and its impacts, in alignment with SDG 13.

SDG 6: Ensuring Sustainable Water Management

Given the water-intensive nature of semiconductor manufacturing, the industry is making significant strides in water conservation, directly addressing the targets of SDG 6.

• Water Recycling and Reuse: The widespread adoption of closed-loop water systems, utilizing technologies like reverse osmosis, has enabled exceptionally high recycling rates. Some facilities, such as those operated by GlobalFoundries, report recycling as much as 98% of process water.
