Designing carbon out before design lock
15%
Original target
~45%
Embodied-carbon reduction achieved
Sustainability data changed the physical product.
My role
Sustainability program lead. I pushed for a 15% embodied-carbon target during early integrated product development, then drove it through engineering and implementation. A member of my team ran the detailed LCA.
The system
Engineering decision → Material change → Supply chain → Byhalia manufacturing → Physical product
Counterweight material
STEEL
CONCRETE
The counterweight went from all-steel to about 40% concrete, a change informed by the lifecycle data.
Decisions & detail
From steel to concrete
A major design innovation replaced steel counterweight material with concrete — an engineering decision, informed by lifecycle data, that changed the carbon profile of the product itself.
The ongoing operating system
- EPD development
- Lifecycle strategy
- Buyer requirements
- Supplier data
- Engineering
- Materials
- Procurement
- Commercial requirements
The supplier-side view
Experience on the equipment-manufacturer side of embodied-carbon requirements: knowing what a buyer's sustainability requirement actually asks of engineering teams and suppliers.
Results
- 15%
- Original target
- ~45%
- Embodied-carbon reduction achieved
TK Elevator's launch release cites a 50% reduction; I use the more conservative ~45%.
Transparency
Transparency
I built TK Elevator's product-transparency capability across EPDs, HPDs, Declare labels, lifecycle analysis and material health, trained internal teams and supported customer adoption.
