Projects and measures

Modernised fleet

In Germany, METRO LOGISTICS has a total of 150 vehicles for delivering to METRO Cash & Carry, Real and Galeria Kaufhof stores. In the reporting year 2013/14, the logistics company replaced a number of vehicles at eight locations which have their own fleets. The 77 newly registered vehicles boast lower fuel consumption as well as CO2 emissions and conform with the Euro 6 standard. The latter defines the limits permitted for exhaust and particulate emissions and is mandatory for newly registered trucks. By modernising its fleet, METRO LOGISTICS plans to reduce its fuel consumption by 140,000 litres and its CO2 emissions by around 2.5 per cent.

Certified building management

Until 31 December 2014, METRO PROPERTIES will be responsible for choosing locations, constructing and managing commercial properties and taking care of energy and facility management for the METRO Cash & Carry sales line. Our primary objective is to increase the value of our real estate assets on a long term basis.

In the financial year 2013/14, an office building at the METRO GROUP headquarters in Düsseldorf and a shopping centre in Poland were awarded the BREEAM certificate. This certificate confirms that a building fulfils certain sustainability criteria. Among other things, the audit rates CO2 emissions, water consumption, energy efficiency, the environmental impact of construction materials, waste generation and building management. In order to speed up the certification of further buildings, six METRO GROUP employees were trained as BREEAM assessors during the reporting year and are now qualified to prepare the evaluation process internally.

Systematic energy data management

The bulk of our energy requirements can be attributed to the lighting, heating and cooling technology used in our stores and outlets and to air-conditioning in our buildings. Because of this, our aim is to identify efficiency potential and optimise our energy usage. In the reporting year, we continued with our programmes to promote energy saving and eco-friendly behaviour on this basis.

*Value adjusted: Unlike in previous years, portfolio adjustments will no longer be made for environmental key performance indicators as of this reporting period (Real sales in Poland, Russia, Ukraine, Romania and Turkey in 2012 and 2013). This means that the prior-year data and the figures for the reference year 2011 differ from those cited in previous years. There are also deviations from emission levels stated in earlier reports; this is due to emission factors being updated and estimates corrected. Particularly in the case of emissions from refrigerants, this gives rise to a slight change in figures all the way back to the reference year 2011.

METRO Cash & Carry

As part of METRO GROUP’s Energy- Saving Programme (ESP), our METRO Cash & Carry sales line invested some €24 million in energy-saving technology for refrigeration units and lighting. In the reporting period, this programme included around 1,600 individual projects with an energy-saving potential of over 126,000 MWh per year. In this way, METRO Cash & Carry was able to reduce its energy costs by over €13.6 million in the reporting period.

In March 2014, METRO Cash & Carry in India signed an agreement to source wind energy from the wind farm operator ReNew Power. The power from the wind farm in Chikodi – located in the state of Karnataka in south-west India – covers approximately 90 per cent of the needs of our two METRO Cash & Carry wholesale stores in Bangalore. By using renewables, the two locations succeeded in reducing their CO2 emissions by 1,750 tonnes per year and their electricity costs by the current rate of 14 per cent.

In the financial year 2013/14, METRO Cash & Carry’s electricity and heating energy consumption totalled 435 kWh per square metre of selling space. This is 36 kWh or 7.7 per cent less than in the corresponding period of the previous year.


The financial year 2013/14 saw our Media-Saturn sales line make further investments in energy-efficient lighting for its locations. LED light strips have now been installed in almost 20 stores. This allows savings of around 40 per cent in energy usage compared with the lighting that was previously used (T5). In comparison with older lighting solutions (T8), the savings potential is even higher. In the reporting year, our sales line achieved a Return to invest ROI of two to four years for these lighting updates, each of which allows an average of over 55,000 kWh to be saved every year. Media-Saturn is also striving to further optimise energy efficiency in other countries. In June 2014, the energy management systems at eleven Italian stores were certified by the local organisation Certiquality in accordance with the ISO 50001 standard.

In the financial year 2013/14, Media-Saturn’s total electricity and heating energy consumption was 248 kWh per square metre of selling space. This is just under 18 kWh or 6.7 per cent lower than in the corresponding period of the previous year.


Real is taking a bundle of measures at its hypermarkets to protect the environment, save energy and reduce costs. These include installing more energy-efficient ovens at its in-store bakeries and fitting glass doors to the chiller cabinets containing fresh products. Measures such as optimising the lighting, replacing the fans in the chillers and gradually replacing ready-to-use refrigerators also help to improve energy efficiency at the various locations. In the reporting year 2013/14, these measures brought about energy savings of around 36,500 MWh.

Real raised the bar for climate and resource protection with its store in Essen’s Altendorf district which opened in October 2013. Not only were 150 trees planted in the store’s grounds but greenery was also planted over much of the roof. This serves as natural insulation that saves on heating costs, cools the urban space and also helps to protect against flooding owing to its high water retention capacity. The wooden roof support structure also helps to reduce CO2. A combined heating and cooling system and modern LED lighting in the chillers both ensure energy is used efficiently. The entire store is geared towards minimising the use of resources, thereby setting an example for modernising other hypermarkets.

In the financial year 2013/14, Real’s total electricity and heating energy consumption was 394 kWh per square metre of selling space. This is 53 kWh or just under 12 per cent less than in the corresponding period of the previous year.

Galeria Kaufhof

Galeria Kaufhof is also working to drive down energy requirements even further at its outlets by means of various measures and projects. Since 2011, our sales line has reduced its consumption of electricity and heating energy at its outlets by over 13 per cent. Energy-saving bulbs have replaced area lighting in 68 outlets and escalator lighting in 69 outlets. In a further 41 outlets, the “starry sky” ceiling lighting and a number of advertising boards have been replaced with LEDs. Galeria Kaufhof makes a point of switching its illuminated advertising to LEDs every time an outlet is renovated.

Thanks to the use of CO2 detectors, the fresh-air circulation system at the department stores now supplies fresh air automatically whenever required. In addition, the heating, ventilation and cooling systems have been optimised. This step was taken in 14 further outlets in the financial year 2013/14. The introduction of systems for measuring and controlling indoor parameters such as temperature, air quality and air flow volume forms part of an agreement between Galeria Kaufhof’s management and its Works Council. This agreement aims to optimise the heating and ventilation systems and their usage in order to further reduce energy consumption at the outlets. Involving employees helps to ensure the long-term success of such measures.

In the financial year 2013/14, Galeria Kaufhof’s total electricity and heating energy consumption was 353 kWh per square metre of selling space. This is 25 kWh less than in the corresponding period of the previous year – equivalent to a reduction of 6.7 per cent.

Managing refrigerant losses

We need refrigerants to store and transport our products properly as well as to present them to our customers at our outlets. Leakage losses in our refrigeration systems is a major source of greenhouse gas emissions as well as being a significant cost factor for the company. Accordingly, our aim is to reduce emissions from refrigerant losses by a total of 29 per cent by 2020.

During the past year, we developed the refrigeration system logbook (Locs*) with a view to identifying leaks in refrigeration systems early on and shortening response times. Among other things, it records the quantities of refrigerants used and the amounts required for refilling. In January 2014, we started rolling the programme out gradually at all our sales lines.

We have been conducting at least four leak tests a year on all refrigeration systems at Real and Galeria Kaufhof in Germany since 2012. At 15 Real and METRO Cash & Carry outlets, we have also switched our commercial refrigeration systems to natural refrigerants such as carbon dioxide. These have a far lower greenhouse gas potential than the gases that are conventionally used. METRO Cash & Carry has also agreed on a programme for phasing out the use of F-gases by 2025, which it has started implementing.

Energy awareness in practice

Our efforts to meet our climate protection targets do not only rely on technical innovations but also on changes in each and every employee’s behaviour. To this end, each of our sales lines has launched its own energy-saving programmes designed to motivate employees to use energy efficiently, thereby bringing about a significant reduction in the company’s overall consumption.

METRO Cash & Carry’s Energy Awareness Programme (EAP) aims to reduce energy consumption by means of various initiatives coupled with technical measures. For example, since spring 2013, employees have been invited to take part in a company-wide “Energy Saver of the Year” competition. This included the categories “Best energy saver at home” “Best energy saver in a store” and “Best energy-saving idea”. In May 2014, prizes were awarded to the entrants with the best ideas and the wholesale stores which saved the most electricity.

In January 2014, Real published an employee guide to saving energy, illustrating easy ways to reduce energy use.
