Chief Sustainability Officer — Advanced-Node Design Organisation

The mandate

A Japanese advanced-node design organisation is strengthening supply assurance across foundry, advanced packaging and critical materials while customers request product-impact evidence. Current continuity plans and footprint calculations use different route assumptions. An urgent new Chief Sustainability Officer will connect qualified supply, supplier impact and customer claim.

Approximately 1,200 employees and material partners span design, product, operations, supply and functions. The CSO owns sustainability, product footprints, responsible sourcing, transition, claims and assurance and reports to the Group Chief Executive or sponsor.

Advanced-node evidence will include electricity, process gases, water, die area, yield, packaging, test and logistics. Supplier averages cannot support route-specific claims when the actual product differs.

Alternate supply may improve resilience while changing impact or responsible-sourcing risk. The CSO will make trade-offs explicit and preserve engineering and quality qualification.

Water and energy need place-based context. Supply plans will consider local utility and community resilience, not only global intensity.

Allocation of renewable or certified attributes requires controlled custody, eligibility and period. Double counting or marketing ahead of verification is prohibited.

Process-gas evidence needs technical detail. Reported electricity improvements can be outweighed by gas use, abatement performance, scrap or rework. The CSO will require suppliers to disclose material methods and uncertainty and will avoid comparing nodes or routes without normalising yield and product function.

Advanced packaging creates its own footprint and responsible-sourcing questions. Substrates, interposers, metals, chemicals and test can shift impact beyond fabrication. Supplier mapping will include important sub-tiers, origin, labour and community risk and corrective-action quality rather than relying on a direct supplier certificate.

Water and utility resilience will use place-based scenarios. A site with efficient intensity may still depend on a stressed basin or fragile infrastructure. The supply-assurance plan will consider conservation, emergency allocation, community needs and recovery, not merely global averages.

Customer product data requires stable boundaries, version and change notice. A foundry, package or yield change can invalidate previous figures. The CSO will maintain approved claim records and a correction route across tenders, customer reports and public materials.

Transition contracts will tie premiums and long-term commitments to verified additional capability. Renewable power, abatement and supplier improvement need volume, evidence, maintenance and exit terms. Finance will validate realised impact and stop projects that cannot demonstrate physical outcome.

Severe disruption scenarios will identify which claims pause when the product route changes temporarily. Continuity does not permit the organisation to allocate environmental attributes it no longer controls or to omit emergency logistics and yield consequences.

Design choices can reduce impact and concentration before sourcing. Die area, package complexity, test time, power and repairability influence footprint and supplier options. The CSO will bring lifecycle evidence into architecture reviews without claiming authority over technical sign-off.

Responsible transition includes supplier workers and communities. Abrupt exit after an adverse finding can hide rather than remedy harm. The team will define corrective milestones, grievance evidence and supported exit where necessary and will not treat a replacement certificate as proof of improvement.

Public and customer claims will use the same method and source. Tender, investor and corporate materials cannot present incompatible boundaries. Corrections will reach known recipients and archived versions, with finance and assurance involved where material.

Sustainability incentives will reward verified outcome, not purchased certificate volume. Leaders must not benefit from allocating attributes ahead of eligibility or from reducing reported intensity by shifting production. Independent review will test physical and accounting evidence.

Transition reporting will state uncertainty ranges and material methodology changes, preventing apparent annual improvement that results only from a revised factor or boundary.

The new role is urgent because foundry and customer decisions are active. The CSO will build a small team and embed ownership in sourcing and product.

What you will own

• Establish route-specific lifecycle evidence.
• Integrate sustainability with supply assurance.
• Govern supplier data, responsible sourcing and claims.
• Shape alternate-source and product decisions.
• Build transition plans and assurance.
• Correct unsupported claims.
• Engage customers on comparable boundaries.
• Develop functional sustainability capability.

The first 12 months

In the first 45 days, map priority routes, claims and supplier gaps and pause unsupported statements.

By month six, deploy a controlled footprint method, complete enhanced diligence and integrate impact evidence into alternates.

At twelve months, cover 85% of priority volume with route-specific evidence, reduce selected footprints by 10% and close 90% of high-risk supplier actions. No material claim should require withdrawal or exceed verified allocation.

What the sponsor will measure

• Claims following actual qualified routes.
• Yield and process gases included in evidence.
• Water and community context visible.
• Alternate-source trade-offs explicit.
• Attributes allocated without double counting.
• Sustainability owned across functions.

The person

You bring 18–22 years in semiconductor sustainability, sourcing, engineering or supply assurance in Japan. You have changed a supplier or product decision through lifecycle evidence.

Your prior scope should include ¥100 billion supply or 900 employees and partners. Evidence must include a route-specific footprint, supplier challenge and customer claim.

Compensation and terms

Base compensation is ¥38–50 million plus annual incentive linked to verified transition, supply assurance, claims, suppliers and leadership. The permanent Tokyo appointment operates onsite and is accountable to the Group Chief Executive or nominated executive sponsor. Prompt appointment is preferred.

Confidentiality

The organisation, products, routes, suppliers, customers and impact data remain confidential. Detail follows suitability, conflicts and signed confidentiality. Applicants must not approach suppliers or customers to identify the enterprise.
