Living Wall (External)
External living wall system with irrigation; provides insulation and urban greening.
Carbon and evidence
Carbon Sink & Ecosystem Services
A living landscape element — a carbon sink and provider of ecosystem services, not a manufactured product. Its value is measured by sequestration and biodiversity, not embodied carbon, and it must never be netted against a product’s A1–A3.
Carbon Sequestration
Not sequestration-led
The primary value here is biodiversity and/or water function, not carbon storage.
Biodiversity Net Gain
small area on artificial substrate; limited BNG value
Source: Defra Biodiversity Metric 4.0
England requires a 10% Biodiversity Net Gain; distinctiveness is one input to the habitat unit calculation.
Ecosystem Services
Establishment & Maintenance
aluminium/steel support frame, growing media and continuous irrigation/pumping carry significant embodied and operational carbon
Read This Honestly
- •Net carbon is genuinely debatable — the support structure and irrigation often outweigh the plants’ sequestration; do not present as a carbon win.
- •High maintenance and water dependency.
