Sustainability guides.

Lighting is one of the simplest ways to cut a building's energy use and embodied carbon. These guides look at how LED retrofit and sustainable lighting contributes to net zero targets, ESG reporting, BREEAM and circular-economy goals, with the figures and evidence you need to make the case.

What these guides cover

• Energy and carbon savings and how to calculate them
• Embodied carbon, reuse and waste
• Reporting and certification

All sustainability guides

• Circular economy lighting: keeping luminaires in use — Circular economy lighting keeps luminaires in service for longer through retrofit, refurbishment and responsible recycling, reducing waste and embodied carbon.
• Embodied vs operational carbon in lighting — Operational carbon comes from the electricity lighting uses; embodied carbon comes from making, transporting and disposing of fittings; retrofit reduces both.
• Disposing of old lighting responsibly — Old lamps, ballasts and luminaires should be disposed of through WEEE-compliant recycling routes, and retrofit reduces how much needs disposal.
• Lighting's role in net zero buildings — Lighting supports net zero through efficient LED, smart controls, daylight use and lower embodied carbon from retrofit and longer-lasting fittings.
• Lighting upgrades and ESG reporting — Lighting upgrades give measurable energy and carbon reductions that support ESG reporting, and retrofit adds a clear waste-reduction story.
