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.
CSRD / ESRS
CSRD, ESRS and Product-Level Data
A corporate report is the sum of product data. Collecting the two separately is one of the most expensive mistakes available.
Construction Products
The DPP for Construction Products and the New CPR
In construction the passport comes not from ESPR but from its own regulation — and will use the same infrastructure.
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.
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.

How to Calculate a Product Carbon Footprint
A carbon footprint is not a number but a sequence of decisions. Six steps to a defensible result, and the mistakes made most often.
