REWE Group Sustainability Report 2018


REWE Group needs the natural resource water both in its own locations and in the production of products in the supply chain. Because water is a limited resource, steps must be taken to ensure its sustainable and economical use.

To permanently integrate sustainability into its company processes, REWE Group has developed an all-encompassing sustainability strategy that is made up of four main pillars: Green Products; Energy, Climate and the Environment; Employees; and Social Involvement. Three areas of action have been defined for the pillar Energy, Climate and the Environment: energy efficiency, climate-relevant emissions and conservation of resources. Activities associated with water consumption are part of the conservation of resources area of action. REWE Group is committed to reducing its use of water wherever possible.

GRI 303: Water

Management Approach

REWE Group uses water in its stores, production sites, warehouses and administration locations. Water-saving equipment installed here reduces the company’s low level of fresh water usage even further.

A bigger role is played by water withdrawal and disposal in the manufacture of products. In this area, REWE Group is working in product-related projects in its supply chain (for more information, see the section Environmental Aspects of the Supply Chain).

GRI 303-1:

Water withdrawal by source

REWE Group uses water in its approximately 15,600 stores, its production sites, warehouses and administration locations. Almost all water used by the company is obtained from public waterworks – with the exception of the rainwater used by some Green Buildings. Total water usage rose from about 6.6 million cubic metres in 2016 to 7.2 million cubic metres in 2018. The increase in usage resulted from the addition of new companies to REWE Group – particularly the establishment of Supermärkte Nord Vertriebs GmbH & Co. KG (SuNo) in 2017 and the addition of REWE Dortmund into the scope of consolidation in 2018. The new warehouses of REWE Digital Fulfilment Services were another cause of increased water consumption. Specific water consumption changed very little year on year.

Water Consumption of REWE Group

Unit 2016 2017 2018 Change
2016 – 2017
2017 – 2018
Total water consumption 1,000 m³ 6,593 6,712 7,184 1.8 % 7.0 %
Energy consumption per square metre of sales area (m³/m²) 0.59 0.58 0.59 -2.2 % 1.1 %

Scope: REWE Group including retailers. The consumption data of the former Kaiser’sTengelmann and Supermärkte Nord Vertriebs GmbH & Co. KG (SuNo) stores have been included in the totals since 2017. Those of REWE Dortmund have been included since financial year 2018. Units that left REWE Group in 2018 were excluded: TEMMA, Gartenliebe, Smart People. The data have been adjusted to reflect these changes. As a result, they do not match the figures contained in the Sustainability Report 2017.
