Sustainability – from workshops to reporting

The obligation for companies to submit a report based on the CSRD has just been postponed by a year and will now come into effect in 2024. This gives you the opportunity to get ahead by devising a long-term sustainability strategy for your company now.

With SUSTAINact, I offer various sustainability workshops (including “Sustainable IT/IT energy efficiency) and comprehensive sustainability consultancy to help with this and am also on hand throughout the entire process to implement your strategy. Depending on how far you want to take things, I can show you not only how to comply with the legal requirements in the future, but also how to create additional competitive advantages for your company and minimize business risks. Make the most of all the opportunities that sustainable business management offers! Because you don’t have to choose between sustainability and growth.

Sustainable IT/IT energy efficiency

2-day workshop

According to a study by the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) the annual energy consumption of IT is already 58.4 TWh (terawatt hours). That’s equivalent to the annual electricity consumption of the whole of Switzerland, and the figure is continuing to grow. Naturally, this is costly for the company, but the environment also pays a high price due to the associated CO2 emissions. In my 2-day workshop “Sustainable IT/IT energy efficiency”, I will show you how to identify your energy-critical IT components – including hardware, software, and operations – and how to use this information to devise initial targeted measures for reducing energy consumption, costs and environmental impact.


I give you 1-on-1 sustainability consultancy

With over three decades of experience working in management roles at various commercial enterprises and with numerous qualifications in sustainability management, I have extensive practical experience and, rather than simply handing you slick presentations, I will guide you every step of the way on your company’s journey to sustainability. My biggest strength is: creating clear structures that work in practice. And I value 1-on-1, open discussions.




Which elements play a particular role in the sustainability of your company? What is important and why? The clue is in the name: Environmental, Social and Governance. ESG reporting is about far more than just CO2 reductions and greenwashing. Here, I will tell you more about the most relevant aspects of environmentally and socially conscious business management:

Corporate Sustainability Reporting Directive (CSRD)

Why is it so important for companies to be sustainable in the future? Based on the European Union’s Corporate Sustainability Reporting Directive (CSRD), certain companies are obligated to report on their sustainability. Affected are all listed companies (excluding micro-enterprises) and companies who meet two of the following three criteria:

Mio € in annual turnover
Mio € in total assets

Therefore, the sustainability reporting obligation applies to around 15,000 companies in Germany alone and will come into force on 1st January 2024 for the 2023 financial year. Those are the facts. The view gets exciting when we look beyond the legal aspects! If you would like to know more about how important sustainability has become to your investors, customers and employees and how you can use it to significantly scale up your success, I would be delighted to have a 1-on-1 conversation with you, or you can get an initial overview here:
