Regulations that rely on these standards
Section titled “Regulations that rely on these standards”Regulations are not standards, but several now depend on LCA-based data. Two matter most in this course:
| Regulation | What it does | Link to the standards | Lesson |
|---|---|---|---|
| Regulation (EU) 2024/3110, Construction Products Regulation | Harmonised rules for construction products on the EU market. Applies from 8 January 2026. Adds life cycle environmental performance to the declaration of performance and conformity, product family by product family. | Its environmental indicators match EN 15804+A2, and its preamble refers to EN 15804 characterisation factors for the Commission’s calculation software | LCA 201 lesson 3 |
| Regulation (EU) 2023/956, CBAM, as amended by Regulation (EU) 2025/2083 | Carbon price on the embedded emissions of imported cement, iron and steel, aluminium, fertilisers, hydrogen and electricity. Definitive period from 1 January 2026. | Uses its own embedded-emissions methodology derived from the EU ETS. Not an ISO 14044 LCA or an EPD. | LCA 201 lesson 4 |
