Sustainability
Keep what still has value. Materials, carbon and the skill in this team.
EGG Lighting was founded in Glasgow. From the start, our work has been grounded in a straightforward idea: the lighting already installed in a building has value — in the materials it contains, the energy used to make it, and the carbon embedded in it. Replacing it without asking whether it can be retained, refurbished, or remanufactured wastes all of that. We built a business around not doing that.
This page sets out what we have actually achieved, where we measure ourselves, and what we are working toward. We apply the same evidence standard here that we apply to our clients: we state what we can verify.
Operational carbon — what we've saved through smarter lighting
Operational carbon — reduced through lower running wattage — has always been the lighting industry's headline metric. It is real and it matters. But it is only half the picture. If you want to size the operational saving on your own estate, use our Energy Savings Calculator for an instant estimate of annual kWh, cost and CO₂e avoided.
Embodied carbon — the metric the industry is catching up to
The other half is embodied carbon: the carbon locked into the materials used to manufacture a luminaire in the first place. When a fitting is removed and sent to landfill or recycling, that carbon investment is written off. When it is remanufactured — disassembled, rebuilt to current standards, and returned to service — the embodied carbon is retained rather than wasted.
This is where EGG Lighting's remanufacturing work is measured differently from the rest of the industry.
We assess whether remanufacture is the right answer, and where it is, we can undertake the work. EGG Lighting has remanufactured fittings at scale — 2,116 at a 150,000 sq ft headquarters in Aberdeen. What a specific programme needs is settled job by job: tell us what you have, and we will tell you what we can do with it.
The standard EGG Lighting contributed to
EGG Lighting contributed to the development of BS 8887-221:2024 — the UK national standard for luminaire remanufacture.
We are also an NICEIC Approved Contractor for installation and electrical work, and are SEPA-licensed for the handling and routing of end-of-life equipment.
Where policy is heading — and where we already are
Scotland's Circular Economy Strategy(2026) uses lighting as a worked example of circular procurement.
We have contributed to the Scottish Government's LACE (Lighting as Circular Economy) procurement guidance, currently in development, which will give public-sector estate managers a structured framework for circular lighting decisions. EGG Lighting's pre-tender survey methodology features in that guidance.
Scotland's AI Strategy 2026–2031 features EGG Lighting as a case study (page 28) on adopting AI across the business: faster first drafts, digital forms replacing paper in the workshop, and an estimated £40k–£60k in cost avoidance.
Our environmental commitment
We are committed to reducing the environmental impact of our own operations as well as those of the estates we serve. That means:
- Measuring and working to reduce our own operational carbon footprint.
- Continuing to develop our embodied carbon methodology, built on CIBSE TM65.2, so our clients have defensible, auditable evidence for their own sustainability reporting.
- Keeping fittings in service rather than in landfill, as our primary contribution to Scotland's circular economy.
We are not yet in a position to publish a formal annual carbon report for our own operations. That is a target, not a current practice — and we would rather state that honestly than claim it prematurely.
Modern Slavery & Ethical Supply Chain
EGG Lighting does not tolerate modern slavery, forced labour, or human trafficking in any part of our operations or supply chain. While we fall below the statutory threshold requiring a formal Modern Slavery Statement (Section 54, Modern Slavery Act 2015 — applicable to organisations with turnover above £36m), we hold ourselves to the same standard: we expect our suppliers and partners to operate ethically and legally, and we review our supply chain accordingly as we grow.
