Chain of custody models for hard-to-abate sectors

Ensure transparency and accountability across your value chain with DNV’s verified chain of custody models, designed to support traceability in high-emission sectors.

Challenges in accountability for hard-to-abate sectors 

Hard-to-abate industries such as steel, cement, chemicals, and heavy transport are under increasing pressure to demonstrate credible progress toward decarbonization. Stakeholders, investors, and regulators demand proof that emission reductions and sustainability claims are traceable and reliable. Chain of custody models play a vital role in establishing trust in the origin, transformation, and movement of materials and emissions data across complex industrial supply chains. 

How our accountability services support you  

DNV offers verified chain of custody models tailored to the needs of hard-to-abate sectors. These models track the flow of raw materials, energy inputs, and emissions-related data throughout the value chain. Delivered through assurance services or integrated audits, these models are aligned with internationally recognized standards and can be used to support claims around recycled content, low-carbon materials, and emission reduction projects. 

DNV’s chain of custody models cover: 

  • Physical segregation.
  • Mass balance.
  • Book-and-claim systems.
  • Attribute tracking and emissions accounting. 

These models provide the transparency and verification required to support ESG reporting, compliance schemes, carbon accounting, and voluntary disclosure frameworks.
