Sustainable Product Declaration (SPD)

Sustainable Product Declaration (SPD) is a structured framework developed by United Metric to provide transparent, traceable and professionally assessed sustainability information at the product level.

The SPD system helps manufacturers document and communicate the environmental, technical and selected ESG-related characteristics of their products through a consistent, evidence-based and reviewable process. It transforms scattered product sustainability data into a structured declaration that can support technical evaluation, procurement processes, supply chain transparency, market communication and sustainability-driven decision-making.

SPD is not a marketing claim and it is not a simple green label. It is a documented process for converting product data into transparent, verifiable and traceable sustainability information.

Why SPD Matters

International markets, construction projects, procurement systems and global supply chains are increasingly demanding reliable sustainability information about products. Quality, price and technical performance are no longer sufficient on their own. Manufacturers are increasingly expected to provide evidence regarding raw materials, sourcing, energy use, water consumption, manufacturing processes, waste generation, lifecycle considerations, responsible production practices and selected ESG-related aspects.

SPD helps manufacturers respond to these expectations through a practical and structured framework. It supports organizations in preparing product-level sustainability information that is clear, evidence-based, reviewable and suitable for professional use in procurement, vendor-list submissions, export discussions, project documentation and sustainability communication.

Core Logic of SPD

The SPD framework is built around three key pillars:

1. Data
SPD begins with the structured collection of product-related information, including raw materials, manufacturing inputs, energy use, water use, packaging, transportation, waste generation, technical documentation and selected ESG indicators.

2. Methodology
SPD applies a structured assessment methodology based on lifecycle thinking, defined system boundaries, declared or functional units, data quality evaluation, sustainability indicators and transparent reporting logic. The framework is designed to balance technical credibility with practical applicability for manufacturers.

3. Verification
SPD includes a review process through qualified assessors and documented procedures. This may include technical review, data consistency checks, methodology review, claim control, registry verification and QR-based traceability.

What an SPD May Evaluate

An SPD assessment may cover product identification, technical characteristics, raw material composition, recycled content, manufacturing process data, energy and water use, emissions, waste, packaging, transport scenarios, lifecycle boundaries, end-of-life considerations, selected ESG indicators, verification status and validity.

The exact assessment scope depends on the product category, available data, system boundary and applicable SPD guidance documents.

SPD Process

The SPD process generally follows a structured workflow:

1. Product or product group selection
2. Scope, boundary and unit definition
3. Data and evidence collection
4. Lifecycle-informed sustainability assessment
5. Selected ESG screening
6. SPD report preparation
7. Independent review
8. Certification, registry entry and QR-based traceability

Upon successful completion, manufacturers may receive an SPD Certificate, SPD Technical Report, Verification Statement, Registry Page, QR Code and a structured public or technical summary.

Target Product Categories

SPD is particularly suitable for construction and industrial products, including cement and concrete, steel and metal products, ceramic and stone materials, paints and coatings, insulation materials, glass and façade systems, doors and partitions, LED lighting, HVAC and building systems, wood-based products and engineered materials.

Registry and Traceability

Each SPD-certified product may be registered in the International and United Metric Registry. The registry may include the product name, manufacturer, certificate number, scope of assessment, issue and validity dates, verification status, public sustainability summary and QR-based access.

This structure supports transparency, product traceability and responsible communication across supply chains and procurement systems.

Key Principles of SPD

SPD is based on five key principles:

Transparency — sustainability-related claims must be supported by data and documentation.
Clear Boundaries — assessment scope and lifecycle boundaries must be clearly defined.
Anti-Greenwashing — SPD discourages vague, misleading or unverifiable sustainability claims.
Verifiability — submitted information must be reviewable and technically assessable.
Traceability — each declaration should include a registration pathway and validity status.

SPD does not simply promote products. It helps make them transparent, reviewable and trusted.
