A careful and pragmatic approach is necessary to strike a balance between sustainability goals and the industry’s growth and competitiveness.
Challenges in Chip Sustainability
Significant emissions in various stages of the supply chain
The manufacturing and usage of chips contribute significantly to emissions throughout their supply chain. Starting from the extraction of raw materials and transportation of finished goods, to the production process involving heating and cooling, and finally to recycling, each stage produces substantial emissions. For instance, the production of silicon, the key material used in chip manufacturing, involves burning a mixture of coal and wood chips. The high energy and water needs of the industry further contribute to its environmental impact. TSMC, the world’s largest chip manufacturer, consumes a significant portion of Taiwan’s electricity and water, leading to water shortages. Additionally, the industry’s contaminants have rendered certain sites toxic, impacting communities and the environment.
High energy and water needs
The chip manufacturing industry has high energy and water requirements, which contribute to its environmental impact. As chip technology advances, the energy consumption in manufacturing processes increases. For example, the production of advanced 3nm chips may consume nearly 8 billion kilowatt-hours annually. This significant energy use puts pressure on limited energy resources and increases carbon emissions. Moreover, the water consumption of chip manufacturers poses a challenge, especially in areas where water scarcity is already an issue. Addressing these high energy and water needs is crucial for achieving sustainable chip production.
Visible impact on communities and environment
The production and use of chips have visible impacts on communities and the environment. As mentioned earlier, the chip manufacturing process consumes a substantial amount of water and electricity, leading to water shortages in certain regions. This can negatively affect the communities residing in those areas. Moreover, the industry’s contaminants have caused pollution and toxicity in some locations, posing health risks to both humans and ecosystems. The visible impact on communities and the environment raises concerns about the sustainability of chip production and calls for the implementation of more environmentally-friendly practices.
Opportunities for Chip Sustainability

Collaboration between chip manufacturers, suppliers, and logistics partners can help identify opportunities for optimizing the supply chain while minimizing environmental impact.
Special flexibility for brownfield chip production
Brownfield chip production, referring to the operation and upgrading of older chip manufacturing facilities, requires special flexibility in sustainability initiatives. Retrofitting older fabs or replacing their tools, facilities, and processes can be costly. The low-margin nature of some chips produced in these facilities further complicates sustainability efforts. Providing special flexibility and support for brownfield chip production can help modernize these facilities without rendering them uncompetitive. This approach ensures that sustainability initiatives consider the unique challenges faced by existing chip production infrastructure.
Balancing Chip Security and Sustainability
Restructuring of supply chains
Chip security concerns have led to the restructuring of supply chains. To ensure the reliability and security of chips, it is essential to diversify sources and reduce dependence on certain regions or countries. However, the restructuring of supply chains should also consider sustainability objectives. A careful balance must be struck to avoid introducing compliance burdens that may compromise the reliability and competitiveness of the supply chain. Balancing chip security and sustainability requires a comprehensive approach that considers both economic and national security demands.
Preventing compliance burden from impacting reliability
While addressing sustainability concerns, it is crucial to prevent the compliance burden from affecting the reliability of chip production. Excessive regulations and compliance requirements can hinder the industry’s ability to meet demand, resulting in supply shortages and economic implications. To avoid such outcomes, sustainability initiatives should be implemented in a manner that does not impede operational efficiency and reliability. This requires collaboration between regulators, chip manufacturers, and other stakeholders to establish clear guidelines and standards that strike a balance between sustainability and reliability.
Meeting economic and national security demands
The chip industry plays a critical role in supporting economic growth and national security. Meeting the demands of both economic growth and national security is essential for sustainable chip production.
