The gentle use of natural resources


The gentle use of natural resources, is today more important than ever before.


We constantly improve our mobility concept.


We plan proactively and sustainably. Our engagement speaks for itself.


We generally aim for long-term goals in our sustainability management.

Dealing with resources

Topic paper:

The paperless office is a vision, that encourages to rethink our own behaviour in our daily business. Nevertheless we are aware, that especially within the planning work, paper can‘t be waived. Therefore it seems more important, to identify areas, where the use of paper can be reduced reasonably.

The following measures have already been implemented successfully:

  • Switching the printer settings to "duplex printing"
  • Use of FSC certificated paper with ecolabel
  • Use of recycling paper for internal printouts in 50% of the office locations
  • Electronic data storage via cloud computing. The usage of the web does not only reduce paper consumption, but also transportation costs
  • Introduction of a "green" auto-signature, in order to reduce paper usage


We regularly rethink our mobility management related to:

  • improving and customising our travel workflow
  • external consulting in order to optimise our mobility processes
  • focusing on state-of-the-art mobility solutions

Sustainable thinking and acting

We plan our projects in a proactive and sustainable way.

Our initiatives in a nutshell:

  • The certificate by the TÜV Thüringen confirms us a Corporate Sustainable Management certification according to the standard "ZNU Nachhaltiger Wirtschaften" of University of Witten/Herdecke
  • The "Learning by Design" prize was awarded to us for "Sustainable Planning"
  • With the charity "Engineers without Borders" our experts have the chance to help on a voluntary base with their individual expertise
  • Our workforce certifies us authenticity and transparency with the official labels "Top Company" and "Open Company" by kununu
  • The "DQS" label confirms us profound quality management

Key ecological objectives, indicators & facts

Due to the long-term nature of our projects and the associated high volatility in the independent consulting engineers branch, we generally aim for long-term goals in our sustainability management. We also develop our measures accordingly. Therefore, our core objectives are based on the year 2015 with a target horizon until 2021. We intend to follow this up by setting new targets up to 2025 based on the 2021 figures.

Use of Resources

In 2015 the primary energy consumption at Dorsch International per full-time equivalent employee (FTE) was 19.76 MWh per annum. By 2020 consumption per FTE was down to 4.88 MWh* per annum, representing a massive reduction in primary energy consumption of -75 %* within a period of two years.

This result exeeds by far the initial target for 2021 to reduce the energy consumption by 2021 by 30 % compared to 2015.

This includes a 1.77 MWh electrical energy consumption in 2015 per FTE and 0.68 MWh* per FTE in 2020, representing a huge reduction of -62 %* per FTE.

Paper consumption per FTE dropped in 2020 by -64%* or -20.04 kg* compared with the peak year of 2015. The consumption of printer paper and plotter paper per FTE was 31.21 kg in 2015, and 11.17 kg* in 2020.

There has been a reduction in the amount of waste per FTE from 46.38 kg (in 2015) to 41.71 kg (in 2020), representing a reduction of -10 %.


At 16.19 MWh per FTE in 2015 the energy consumption levels for mobility at Dorsch International were substantially higher than in 2020 when levels showed just 5.91 MWh*. This was achieved first and foremost thanks to a significant reduction in airline travel in favour of more sustainable means of transport and fewer long distance flights, but in 2020 also to the partial Corona lockdown. The overall result was a -86 %* reduction for mobility alone.

Particulate emissions per FTE also dropped from 0.15 kg in 2015 to 0.04 kg* in 2020, this also representing a decrease of -73%*.

CO2 Emissions

CO2 emissions per FTE in 2015 were 2.90 t compared with 1.15 t* in 2020, representing a decrease of -70 %* over a period of five years.

We exceeded our initial target to reduce the CO2 emissions from 2015 to 2021 by 20 % already last year with -30 %.

* The uncharacteristically high reduction in energy consumption and CO2 emissions in 2020 is caused mainly due to the one-time effects of the Corona crisis. Our long-term goals are thereby far exceeded, but it is expected that these figures will noticeably go up in 2021/2022. It is assumed that the figures will still remain on a significantly lower level than in 2015, still meeting our long-time targets. Our targets will be redefined for 2022 and later.
