Reporting 2020

Energy Management

We are continuously working to increase our energy efficiency. We are also looking to generate more of our own electricity from renewable sources.

Energy management is an important means of increasing our efficiency and thus leveraging economic and environmental potential – it is also essential for achieving our climate protection target. Our on-site energy officers are responsible energy planning at the individual locations. In addition to systematic data capture, this involves regular energetic evaluations as well as documenting planned and implemented measures. All activities are monitored and managed by a central controlling unit. In the reporting year, our energy management system was re-certified according to DIN EN ISO 50001 at 26 locations. At other locations, pending energy audits according to DIN EN 16247 were completed. Our environment management system has been certified in accordance with DIN EN ISO 14001 since 2014 at all German locations in the AUTOMOBILE Division as well as eight more contract logistics centers.

This report for the first time also includes the energy consumption figures for our fully consolidated foreign locations; however, our overall focus remains strongly on Germany. One reason for this is that at 85 percent Germany accounts for the lion’s share of the energy requirement, another is that the foreign locations for the most part assume responsibility for this topic themselves. In the remainder of this section, therefore, graphics and analyses relate to our fully consolidated German sites unless stated otherwise.

Basis: Calculating our consumption data

In order to permanently reduce our energy consumption – and hence greenhouse gas emissions – we need to know precisely where energy is consumed. For this, we rely on decentralized recording, validation and evaluation by our energy officers on site. Not included are sites, plants and vehicles whose energy consumption we cannot control. The consumption of all fully consolidated companies is aggregated and calculated by the central Sustainability and Digitalization department as part of the annual energy and CO2 accounting.

Parallel to formulating our new climate protection target, we also published a revised version of our energy policy that has been in force since 2016. In addition, in interviews conducted with our energy officers in 2020 we evaluated the tools used to capture data and document measures taken. Subsequently, optimization proposals were developed, among other things for the renewal of these tools and also for best practice communication. The results from the survey were also factored into the specifications for comprehensive energy management software for evaluation, analysis and documentation, which it is planned to select in the course of 2021 and introduce across the company in a timely manner.

Energy consumption in the reporting year

Our global energy consumption in 2020 was 263 million kWh, with the German locations accounting for 222 million kWh of this amount. Here, 59 percent of the total consumption was attributable to the AUTOMOBILE Division, while car transports and their consumption of diesel fuel were, in turn, the biggest consumer with 41 percent. In industrial and retail logistics, which are both included in the CONTRACT Division, the biggest consumers were cross-sectional technologies such as heating and air conditioning technology and lighting. Compared with the previous year, we were able to report savings for all energy sources with the exception of district heating. However, the 8.8 percent reduction in energy consumption for the reporting year must also be seen against the background of the effects of the coronavirus pandemic.

Measures to enhance efficiency

As in many other areas, the implementation of energy efficiency measures was also impacted by the coronavirus pandemic in the reporting year. Projects that had been planned were in some cases stopped or postponed by at least a year. The following projects were nevertheless continued or brought to completion.

For example, we completed the renewal of the heating control system at our high-bay warehouse in Bremen and calculated the respective savings. In the past, the control regulators were distributed decentrally across the site and were sometimes difficult to access; in addition, the settings on the programming cards were not displayed uniformly. Operation was correspondingly time consuming. After replacing and combining the three higher-level controllers in a single interface, access is now via web browser. This means that the shift-by-shift adjustment of temperature and time programs can be carried out quickly and easily and unauthorized access can be prevented. Not only did the measure pay for itself within just six months, it also saved 1.3 million kWh of gas over the course of the year, which translates into an avoidance of 305 t CO2e.

LED projects already underway at various locations were continued. At the Bremerhaven car terminal, which has already been largely converted, first test areas were defined for the outside areas – here, by adjusting the control of the outdoor illumination, it is hoped that further savings can be achieved in the future. We already require 1.3 million kWh less, equivalent to around 350 t CO2. Fitting LEDs in conjunction with an intelligent control system was also a focus at our logistics center in Bremen. Here, in a first step, three out of nine buildings with a surface area of around 28,000 m2 were converted, reducing the connected load by 50 percent, equivalent to a yearly saving of 174,000 kWh. Thanks to daylight-dependent control, we are able to realize additional savings potential while improving illumination intensity and lighting quality. The remaining buildings will follow in 2021. Across all facilities, conversion to LEDs in the meantime results in annual savings of around 2.4 million kWh of electricity.

Communicating knowledge and raising awareness

Once again in the reporting year we kept our employees continuously informed about topics related to energy efficiency via various formats – above all through training courses and notices. Unfortunately, however, the coronavirus pandemic meant there were restrictions here as well. Thus the TechnikTreffen (technical meetings) that normally take place in-person were replaced by smaller online events dealing with topical issues. The training up of new energy officers in BLG’s climate and energy management was also done digitally in 2020.

UN goal: Ensure access to affordable, reliable, sustainable and modern energy for all

Energy Management is a central lever for dovetailing economic and environmental effects. In addition to increasing energy efficiency, we are also increasingly focusing our climate protection activities on the integration of energy from renewable sources.

New solutions: For clean energy and lower consumption

Since 2019, a photovoltaic system has been in operation on the roof of the car terminal in Kelheim. It has a generator area of 430 m2 and an output of 74 kWp. A similar system ten times the size went into operation at the Waiblingen site in 2020, where we can also utilize the solar power generated there. In the reporting year, we utilized over 80 percent of the clean energy from both facilities ourselves. Like this, we were able to cover an electricity requirement of around 73,000 kWh, which is equivalent to avoidance of 17 t CO2e.

Our company BLG AutoTransport offers transport services for new and used vehicles and in the reporting year operated its own fleet of 195 trucks in Germany. Having already expanded the fleet by 70 new vehicles in 2018 and 2019, we invested in a further ten in the reporting year. 99.5 percent of the fleet complies with the EURO 6 standard. Consequently, the average diesel consumption by BLG AutoTransport in the reporting year fell once again. At 29.5 liters per 100 kilometers, this figure is again below the previous year's value.

We are also working continuously on modernizing our fork-lift truck fleets. At several locations, we replaced the entire industrial truck fleets in the reporting year. The new vehicles use lithium-ion and high-frequency charging technology. We also already have hydrogen forklifts in operation at one site.
