Optimizing our environmental footprint

Our manufacturing activities have already substantially reduced their environmental impact. Today we continue our efforts in five priority areas: strengthening environmental management processes, reducing water usage and securing supplies, improving energy efficiency in manufacturing and transportation, reducing carbon footprint and adapting to climate change and limiting waste generation and optimizing recycling.

Reducing our water

Essilor has already made significant progress over the last fifteen years in reducing the water used to produce each lens, taking into account local supply constraints. Our challenge today: making further small gains and sharing good practices to smooth the variances that still occur between our production sites. This has been the objective of the Reboost Water program which has enabled us to map out the water consumption of our main production sites, compare performance and define medium-term water consumption reduction plans.

Did you know?

In 2018, Essilor was awarded with the A- (leadership) score by CDP (formerly the Carbon Disclosure Project), positioning it among companies which have made ambitious commitments to optimize water use and improve the security of water resources.

Improving our energy

We are committed to improving our energy efficiency, as reflected in a steady decrease in energy intensity over the last 15 years. Essilor has also voluntarily contributed to the work of the CDP an international, independent non-profit organization that assesses companies’ efforts to measure and reduce their greenhouse gas emissions and water footprint. In 2018, the Group was again awarded an “A-” (leadership) rating in recognition of its efforts and continuing investments, having shown leadership in this area.

Today, having achieved the most significant gains, our main work is improving the energy performance of buildings and analyzing for further energy efficiency improvement in our manufacturing processes.


Limiting our carbon

The nature of our business means we have a light environmental impact. Nevertheless, we believe that limiting our carbon footprint is an opportunity to reduce costs associated with our business such as energy and transport, limit our energy dependence even if it’s modest, anticipate the introduction of binding climate agreements (taxes, quotas …) and meet investor or analyst expectations, as well as those of our major customers.

Following the achievements of the Paris Agreement and the United Nations COP23 conference, we signed up to the French Climate Pledge in 2017, along with 91 other French companies which have committed, over the following years, to limit the impact on climate, notably by financing energy efficiency programs, optimizing production equipment and logistics chains, and innovating in the field of low-carbon products and services.

Managing waste towards
circular economy

To minimize waste, we eco-design new products and optimize our production processes. The scrap and residue from the polycarbonate lens surfacing process are compressed, reducing the weight of waste and collecting water which is then filtered and fed back into a prescription laboratory’s internal system. We recycle and reuse certain used effluents (oils, acids) in our facilities.
