Sustainability
Nothing wasted. Not materials. Not carbon. Not the skill in this team.
EGG Lighting was founded in Glasgow in 2013. 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
Since 2013, we have worked with more than 300 organisations across the UK, upgrading legacy lighting to high-efficiency LED technology. The cumulative energy savings from that work have avoided an estimated 13,000 tonnes of operational CO₂ emissions — the carbon that would otherwise have been released generating the electricity those older fittings consumed.
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.
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's remanufacturing work is measured differently from the rest of the industry.

Tonnes of embodied carbon saved
Every remanufactured fitting leaves our workshop with a five-year warranty, a measured photometric file, a UKCA declaration of conformity, and a Digital Product Passport — a record of what it contains, what was done to it, and what its carbon footprint looks like. That documentation matters increasingly for BREEAM assessments, Scope 3 reporting, and the corporate carbon disclosures that estate owners are now expected to produce.
The standard we work to
Our remanufacturing process is built to BS 8887-221:2024 — the UK national standard for luminaire remanufacture, to which EGG contributed during development. Every fitting we return to service is treated as a new product for compliance purposes: full conformity assessment, testing, and certification. We accept the legal responsibility that comes with that.
We are also NICEIC Approved Contractors for installation and electrical work, and hold SEPA authorised treatment facility and waste carrier licences (ATF WML/XS/1196741; WCR/R/1196232) for the handling and routing of end-of-life equipment.
Where policy is heading — and where we already are
Scotland's Circular Economy Strategy, published by the Scottish Government in March 2026, cites lighting as the worked example of circular facilities management in the public estate — buildings where fittings are retained, reused, and remanufactured rather than replaced. That is a description of what EGG has been doing since 2013.
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's pre-tender survey methodology features in that guidance.
EGG is also featured as a named case study in Scotland's AI Strategy 2026–2031, recognising our use of AI to scale circular lighting manufacturing — delivering an estimated £40k–£60k in cost avoidance and cutting documentation time without growing headcount.
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.
