Carbon Footprint and the Product Passport
The carbon footprint is the passport's most-scrutinised data. We explain how it is calculated, its link to CBAM, and correct declaration.
Life Cycle Assessment
Life Cycle Assessment (LCA) Basics
LCA measures a product's cradle-to-grave environmental impact. We simplify the method behind the DPP's carbon and environmental data.
Circularity
Circularity and Recyclability Data
The passport's real purpose is to make circularity measurable. We explain why repair, disassembly and recycling data sit at its centre.
Life Cycle Assessment
Primary vs Secondary Data: Which and When?
Measuring is expensive; database averages can be misleading. The rules for striking the right balance.
Circularity
How to Prove Recycled Content
Saying "30% recycled" is easy; proving it is not. Chain-of-custody models and what evidence belongs in the passport.
Life Cycle Assessment
What Is an EPD? Environmental Product Declarations and the DPP
A verified, rules-based and comparable environmental statement. Why construction and B2B tenders keep asking for one.
Life Cycle Assessment
What Is PEF? The Product Environmental Footprint Method
The EU's comparability methodology: PEF's scope, the role of PEFCRs and when it actually becomes necessary.
Life Cycle Assessment
ISO 14040, 14044 and 14067 Compared
Which standard when? The scope of each, how they relate, and what they mean for verification.
