Quantitative insights into embodied carbon savings when choosing retrofits
When it comes to reducing a building’s carbon footprint, lighting is often one of the first systems to be upgraded. But there’s a crucial distinction many sustainability strategies still overlook:
Replacing with new LED fittings vs Retrofitting and remanufacturing what you already have.
While both reduce energy consumption, only one seriously tackles the embodied carbon problem.
What Is Embodied Carbon in Lighting?
Embodied carbon refers to the total greenhouse gas emissions produced during the manufacture, transportation, and disposal of a product. For lighting, this includes:
-
Raw material extraction (e.g. aluminium, copper, plastic)
-
Component manufacturing (gear trays, diffusers, casings)
-
Assembly and transport to site
-
End-of-life treatment (e.g. landfill or recycling)
Even before it’s switched on, a new LED luminaire has already created a carbon debt.
The Real Numbers: New vs Retrofit
Let’s break it down.
-
Typical new LED panel (600x600mm):
~25–35 kg CO₂e embodied carbon per unit -
Revitalite retrofit (using existing fitting):
~3–5 kg CO₂e embodied carbon per unit
That’s up to 85% less embodied carbon per luminaire by choosing retrofit over replacement.
In a 200-light fitting office, the choice becomes:
| Option | Embodied Carbon (Total) |
|---|---|
| New LED Luminaires | 6,000 – 7000 kg CO₂e |
| Revitalite Retrofits | 600 – 1000 kg CO₂e |
That’s the equivalent of removing 20+ long-haul flights’ worth of carbon emissions — just by reusing your existing light fittings.
Why Retrofit Wins in Sustainability Reports
Choosing retrofit lighting helps you:
- Reduce scope 3 emissions
- Support circular economy principles
- Minimise landfill waste
- Improve green building credentials (e.g. BREEAM, SKA, LEED)
- Demonstrate environmental responsibility to stakeholders
It also aligns with PAS 14191 and the BS 8887 remanufacturing standard — ensuring your upgrades are auditable and aligned with recognised carbon-saving frameworks.
Remanufacturing Isn’t a Compromise — It’s an Upgrade
Revitalite doesn’t just preserve the housing — we replace all the old internal components with high-performance, energy-efficient LED gear, fully tested and compliant with modern standards.
So you get:
-
Lower embodied carbon
-
Lower operational carbon
-
Lower waste
-
Lower cost
With no compromise on light quality, longevity, or aesthetics.
