As the world continues to grapple with climate change, sustainability is no longer a niche concern but a necessity. Everyday choices such as the way we light our homes, hotels, and workplaces can play a meaningful role in reducing environmental impact.
Lighting accounts for a significant share of global energy use, and decisions about materials, production, and efficiency all influence the sector’s carbon footprint. Sustainable lighting, therefore, represents both a practical and symbolic step toward more responsible living.

Rethinking the materials of light
Designers and manufacturers are increasingly turning to natural and recycled materials to reduce waste and reliance on virgin resources. Some of the most prominent materials in sustainable lighting today include:
-
Ceramics: Durable and natural, ceramics can be produced with relatively low environmental impact, especially when modern, energy-efficient kilns are used.
-
Rattan: A rapidly renewable palm-based material, biodegradable and well-suited to woven shades.
-
Abaca: A fibre from banana plants, strong, biodegradable, and often derived from agricultural by-products.
-
Raffia and Jute: Plant-based fibres offering both renewability and a natural aesthetic.
-
Recycled Brass and Glass: Materials that can be remelted and reused without loss of quality, reducing the demand for new raw inputs.
Each brings distinct design possibilities while also supporting lower-carbon manufacturing.
Beyond aesthetics
Sustainable lighting is not solely about what a product is made of – it is also about how long it lasts and how much energy it consumes. LEDs, for example, use up to 75% less energy than incandescent bulbs and last considerably longer. When paired with durable materials such as brass or glass, lighting products can remain in use for decades, limiting both replacement costs and waste.

Enter Mullan Lighting
An Irish manufacturer, Mullan Lighting, offers one example of how sustainability principles can be applied across production. The company has adopted a made-to-order model, reducing overproduction and surplus stock. Its workshop incorporates eco-friendly materials, including recycled metals and plant-based fibres, into many designs.
The factory itself integrates renewable energy and efficiency measures, such as solar panels, energy-efficient windows, and motion-sensitive lighting, to cut overall consumption. Waste reduction is addressed through recycling programmes that align with industry standards such as WEEE compliance and Repak certification.
Mullan Lighting has also mapped its practices to the United Nations’ Sustainable Development Goals, underscoring the wider social and environmental context of its operations.

Lighting the way forward
Sustainable lighting may not, on its own, solve the climate crisis. But it is one tangible area where individuals and industries can act. Whether by choosing long-lasting LED fixtures, selecting products made from recycled or renewable materials, or supporting manufacturers with transparent sustainability commitments, consumers can contribute to broader environmental goals.
In an era of environmental urgency, lighting offers a clear example of how design, technology, and responsibility can converge. Choices made today, by both producers and consumers, will help shape a future that is not only brighter, but greener.
