Legrand Legrand

A different vision of water for Legrand sites

The Group manages its water consumption according to the local availability of this valuable natural resource.

Since it has existed, Legrand's environmental reporting has covered water use on industrial sites. Our production sites have undertaken numerous projects to reduce their use of water, in particular through the installation of closed-loop cooling circuits.

But to measure the impact of Legrand activities, we need not only to measure the volume of water used by sites, but also its value in the local context.
Two essential elements are to be taken into consideration in estimating this value: the natural availability of water and competition for access to the resource. For the regions of the world that suffer from hydric stress, i.e. where water consumption exceeds the natural capacity for its renewal, consumers need to seek it at ever deeper levels. This situation is obviously not sustainable.

 

It was therefore essential for the Legrand Group to manage its use of water resources on a site-specific basis, by taking into consideration the local scarcity of water. To achieve this, the Environment Department used data supplied by the United Nations Environment Programme (UNEP). In practical terms, we used a tool that maps out all the regions of the world and assigns them a value on the Water Scarcity Index (WSI).

This analysis enabled us to determine that over 83% of Group water consumption occurs on sites located in areas where water use is low to moderate (WSI equal to or below 0.7).

Moreover, this approach enables our divisions to take priority action on the most sensitive sites in terms of their environmental impact on the local water resources.
