Environmental management system

One of the ways in which the effectiveness of DEUTZ AG's environmental management system can be seen is that key aspects, such as sustainability, are taken into consideration when workstations are being planned. The system has had its compliance with DIN EN ISO 14001 reconfirmed by the certification body DNV GL 2016.

For example, when shaft production was relocated from the Cologne-Deutz site to Cologne-Porz, the supply of coolant was centralised at the same time. This has a number of advantages in the machining of shafts. Centralised control of the system means it is no longer necessary to monitor a large number of individual machines. The useful life of the cutting fluid can now be used optimally, thereby conserving resources and reducing hazardous waste. Permanent, centralised monitoring of key parameters of the cutting fluid also ensures a high level of manufacturing quality. This is directly beneficial from both a financial and an environmental perspective. We anticipate that fluid consumption will decrease by between 5 and 10 per cent this year.

Internal environmental and energy audits, which are conducted by a team of specialists according to a defined schedule, help to ensure that the processes being audited comply with statutory requirements and that departmental targets are met. Our environmental management system also helps in this regard and its rule set is continuously updated and analysed to ascertain at an early stage whether any process changes are needed.

In 2016, DEUTZ AG began to implement the new requirements arising from the risk- and opportunity-based approach of the ISO 14001:2015 standard for environmental management. The first results, particularly the assessment of opportunities, will be examined by the external auditors in spring 2017.

Focus on reducing emissions

The assessment of environmentally relevant processes has shown that the emissions from operating the engine test bays during development and production have a strong impact on our environmental footprint. To be able to better evaluate the overall impact, DEUTZ analyses total annual emissions of the greenhouse gas CO2 as well as of the pollutants dust, nitrogen oxide and benzene.

DEUTZ Group: Annual CO2 emissions in our plants 1)    
  2016 2015
CO2 emissions (Scope 1) 13,433 13,251
CO2 emissions (Scope 2) 51,315 51,070
CO2 emissions (Scope 3) 1,224 532
Total CO2 emissions 65,972 64,853
Scope 1: CO2 emissions caused by combustion in our own facilities.
Scope 2: CO2 emissions relating to purchased energy (e.g. electricity, district heating).
Scope 3: CO2 emissions from flying and the use of hire cars.
1) Plants in the DEUTZ Group, excluding joint ventures.

Another analysis shows total CO2 emissions resulting from the direct or indirect consumption of energy per engine produced during the reporting period:

DEUTZ Group: Emissions per engine in our plants 1)    
  2016 2015
Emissions per engine    
Carbon dioxide (kg) 470 460
Nitrogen oxide (kg) 0.22 0.128
Dust (g) 2.7 2.6
Benzene (mg) 2) <85.0 44.8
1) CO2 in plants in the DEUTZ Group, excluding joint ventures. The other data relates to German plants.
2) Measurement uncertainty is three times higher than the measured value.

There was a small year-on-year increase in carbon dioxide emissions per engine, which rose by 2.2 per cent. This means that the target of reducing carbon dioxide emissions by 2.0 per cent per engine produced was not achieved. The reason for this is that around two-thirds of the test bay emissions are attributable to research and development activities, whereas production testing only accounts for about a third. More endurance testing aimed at refining engines with large cubic capacities and improving product quality led to the increase. Ultimately, however, these tests play a part in ensuring that our future engines put fewer emissions and less CO2 into the environment when they later go into operation. The per-engine level of other emissions (dust, nitrogen oxide and benzene) also increased in 2016 for the same reason, even though the revision rate in engine production has been successfully lowered and testing programmes have been significantly streamlined and further standardised.

The state-of-the-art, high-performance exhaust gas aftertreatment system used in the production test bays at the German sites ensures that DEUTZ remains comfortably within permitted limits and, in some cases, is very significantly below them.
