Greenspec PASS

1. Review the PASS criteria: Visit greenspecpass.co.uk to understand the environmental and performance standards that products must meet to qualify for the PASS endorsement.

1. Assess your product's eligibility: Evaluate whether your building material or product demonstrates superior environmental credentials — such as low embodied carbon, responsible sourcing, or reduced toxicity — relative to conventional alternatives.

1. Prepare product documentation: Gather technical data sheets, environmental declarations (e.g., EPDs), third-party test results, and any relevant certifications that substantiate your product's green credentials.

1. Submit your product for review: Complete the GreenSpec PASS submission process, providing all required documentation and product information for assessment by the editorial panel.

1. Peer review by architects and specifiers: Your submission is evaluated by GreenSpec's panel of practising architects and specifiers, who assess environmental performance and suitability for sustainable construction specification.

1. Receive endorsement decision: If your product meets the PASS criteria, it is awarded the PASS label and listed in the GreenSpec green products directory, accessible to UK design professionals.

1. Maintain your listing: Keep your product information up to date in the directory and respond to any requests from GreenSpec for updated documentation to retain your endorsed status.

GreenSpec PASS evaluates building products and materials against a set of environmental and sustainability criteria developed and applied by a panel of practising architects and specifiers. The assessment is holistic rather than based on a single metric, considering a product's overall environmental profile in the context of real-world sustainable construction specification.

Key areas of evaluation include: embodied environmental impact (such as embodied carbon, energy in manufacture, and resource depletion); material health and toxicity (absence of harmful chemicals or substances of concern); responsible sourcing (including recycled content, sustainably sourced raw materials, and supply chain transparency); durability and end-of-life considerations (longevity, recyclability, and waste reduction potential); and performance in use (thermal, acoustic, or other functional properties relevant to sustainable building design).

The peer-review panel also considers whether a product represents a genuine improvement over conventional alternatives — the PASS label is intended to identify products that stand out for their environmental credentials, not simply meet a minimum threshold. Products are assessed in the context of UK construction practice, building regulations, and the needs of design professionals making specification decisions.

GreenSpec is one of the UK's longest-standing independent green building resources, having been established in 2003 with government funding. The PASS product endorsement scheme, launched in 2015, occupies a niche position in the UK sustainable construction market as a peer-reviewed, specifier-led endorsement rather than a formal third-party certification against a published standard. This distinguishes it from more rigorous schemes such as BRE's BES 6001 or the EU Ecolabel, but also makes it more accessible to smaller manufacturers who may lack the resources for full accredited certification.

The program's primary value proposition is its integration with the GreenSpec directory, which is widely used by UK architects, specifiers, and self-builders as a reference for sustainable material selection. Inclusion in the directory provides meaningful visibility among design professionals at the point of specification. However, the PASS label is less well known among end clients and developers compared to internationally recognised schemes such as Cradle to Cradle or EPD declarations, which carry more weight in global supply chains and major procurement frameworks.

Demand for credible green product endorsements in the UK construction sector continues to grow, driven by net-zero commitments, the Future Homes Standard, and increasing client and investor scrutiny of embodied carbon. However, GreenSpec PASS faces competition from a growing ecosystem of product transparency tools — including Environmental Product Declarations (EPDs), Health Product Declarations (HPDs), and BREEAM's recognised products framework — which are increasingly preferred by large contractors and developers seeking standardised, comparable data. The PASS label is best positioned as a complementary endorsement for manufacturers targeting the architect and specifier community in the UK SME and self-build markets.

GreenSpec was founded in 2003 with support from UK government funding as an independent online resource promoting sustainable building design, materials, and construction techniques. Edited from the outset by practising architects and specifiers, it was designed to serve the practical needs of design professionals rather than function as a trade or industry body publication. Over the following decade, GreenSpec grew into one of the UK's most widely referenced green building directories, covering building design guidance, product information, and sustainability techniques.

The GreenSpec PASS (Product Assessment and Selection Scheme) endorsement label was introduced in 2015 as a formalised mechanism for independently recognising building products that meet the program's environmental criteria. The PASS scheme extended GreenSpec's editorial model into a structured product endorsement framework, allowing manufacturers to seek formal recognition for their products' green credentials. The scheme has remained focused on the UK construction market and continues to be operated by GreenSpec Ltd, with evaluation conducted by its panel of architect and specifier editors.
