The Greater Good In the second GreenLight Alliance column, Tiphaine Treins of Temeloy and James Morris-Jones of Lucent Lighting talk about the Lighting for Good (LfG) charter, the Lighting for Good Awards, and Lucent’s work with it.

n May 2018, LVMH Lighting and Temeloy
created ‘Lighting for Good’ (LfG), an eco-design Think Tank, enlisting collaboration from more than 25 lighting suppliers. Its aim is to evolve innovation, services and reliability towards
sustainability in the lighting industry. Lucent Lighting was one of these suppliers.
Acknowledging the energy saving contribution of LEDs to the overall environmental impact of lighting, LfG aims to usher in a new phase
of luminaire design concerned with a circular economy. An economy where efficiency in material usage, easier maintenance and plastics removal are the major headings. A LfG charter was written to judge
eco-design credentials, with exacting requirements that often exceed the parameters of existing regulations. The principal partner in the writing of this charter was CIRAIG—The International Centre for
Life Cycle of Products, Services and Systems. This research group is the centre of expertise on sustainability and life cycle thinking. It
brings together the expertise of two universities in Montreal, Canada – Polytechnique Montreal and UQÀM, as well as two universities in Sion, Switzerland – HES-SO and EPFL.
The environmental impact indicators used in the LfG charter are
inventoried into a Life Cycle Analysis, a method that quantifies the exchanges between the activities included in a product’s life cycle
and the environment, related to the amount of service provided by a luminaire in terms of light output and lifetime. The Ecoinvent v3.6
Lifecycle Inventory Database, released in 2019, was used to generate the trade inventory for a typical fixture. To interpret this inventory,
it is converted into environmental indicators, taking into account the potential of each substance concerned to generate an environmental Tiphaine Treins, Lighting Designer & Founder, Temeloy
