The German Federal Data Protection Act [BDSG] stipulates, in Section 4g, that the data protection officer has to make the following information pursuant to Section 4e available in a suitable way to anyone:

VDI Zentrum Ressourceneffizienz GmbH

2. Managing Directors:      
Dr. Martin Vogt

The website is operated by VDI Zentrum Ressourceneffizienz GmbH on behalf of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

1. Content of the website

The author gives no warranty whatsoever for the information provided being up-to-date, correct, complete, or for its quality. Liability claims against the author that relate to material or non-material damages, which were caused as a result of using or not using the information provided or by using incorrect and incomplete information, shall be excluded unless the author is shown to have acted with intent or gross negligence. All offers are non-binding and without obligation. The author expressly reserves the right to amend, supplement, delete or temporarily or permanently suspend publication of parts of the pages or the entire website.

2. References and links

Direct or indirect references to external websites (“hyperlinks”) or other documents provided on the Internet, which lie outside of the author’s area of responsibility, shall only result in obligations of liability if the author is aware of the contents and if it were technically possible and reasonable for the author to prohibit said use in the event of illegal content. The author hereby expressly states that at the time of adding the link, no illegal content was discernible on the linked site. The author has no influence whatsoever on the current and future design, content or authorship of the linked/connected websites. The author therefore expressly distances itself from the content of all linked/connected websites that have been changed since the link was added. This statement applies to all links and references placed on its own website and to third-party entries made in the guestbooks, discussion forums, collections of links, and mailing lists set up by the author. The provider of the site linked to, and not the provider of the site on which the links reference the respective publication, shall be exclusively liable for any illegal, incorrect or incomplete content and in particular damages resulting from the use or non-use of such information.

3. Copyright and trademark law

The author strives to observe all copyrights of the images, recorded documents, video sequences and texts used in all of its publications, to use images, recorded documents, video sequences and texts it has created or to make use of royalty-free images, recorded documents, video sequences and texts. All brand names and trademarks mentioned within the website and protected by third parties shall be subject to the unrestricted provisions of the respective current trademark laws and the rights of ownership of the respective registered owner. If mention is made of the above, it should not therefore be inferred that brand names are not protected by third party rights! The copyright for published objects created by the author shall remain with the author of the pages. The aforementioned images, recorded documents, video sequences and texts may not be reproduced or used in other electronic or printed publications without the express approval of the author.

4. Data protection

If the website includes the option to enter personal or commercial information (email addresses, names, addresses, etc.), this data may be disclosed by the user on a purely voluntary basis. All of the services offered may, where this is technically possible and reasonable, be used without disclosing such information or by using anonymous data or a pseudonym. This does not include forms for ordering publications or other materials, registration forms for events, and the newsletter. Contact details such as postal address, telephone and fax numbers, and email addresses published in the imprint or similar information must not be used by third parties to send information not expressly requested. The right to take legal steps against the sender of so-called spam emails for breaches of this prohibition is expressly reserved.

5. Data storage

This website uses the web analysis services Google Analytics and Piwik.

Google Analytics

Google Analytics is a web analysis service from Google Inc. (“Google”). Google Analytics uses so-called “cookies”, which are text files placed on your computer, to help the website analyse how you use the site. The information generated by these cookies regarding your use of this website is usually transferred to a Google server in the USA where it is stored. If IP anonymisation is activated on this website, your IP address will be shortened by Google within the Member States of the European Union or other parties to the Agreement on the European Economic Area. The full IP address will only be transferred to a Google server in the USA and shortened there in exceptional cases. Google will use this information on behalf of the operator of this website to analyse your use of the website, compile reports on website activity, and provide other services associated with use of the website and Internet use for the website operator. The IP address transmitted by your browser within the scope of Google Analytics will not be merged with other data by Google.

You may prevent the use of cookies by selecting the appropriate settings on your browser; however, please note that if you do so, you may not be able to use all the functions of this website to their full extent. You can also prevent the data generated by the cookies about your use of the website (including your IP address) being released to Google and the processing of this data by Google, by downloading and installing the browser plug-in available at the following link:


In addition to Google Analytics, the web analysis tool Piwik is also used for this website to understand the user’s access behaviour. The data from the log file, which is stored on the web server solely for the purposes of data security, is not merged with any further saved data, such as that which originates from use of other offers involving giving personal data.
It is not possible to draw a direct link from the IP number in the log file to you personally, and this is excluded, because the IP address is stored in anonymised form by the Piwik plugin AnonymizeIP. The IP address is only analysed in the event of attacks on VDI ZRE’s Internet infrastructure, for breaches of common decency, and for other illegal acts connected to the use of the website. It is therefore only possible to draw an inference from the IP number to you personally via your access provider as part of an investigatory procedure from the police or public prosecutor.

Piwik uses cookies which make it possible to analyse use of the website. This function can be deactivated below. The information generated by the cookies is used exclusively to improve the website and servers. Your IP address is anonymised and cannot be traced back to you. On accessing a website, Piwik saves data on this process. Specifically, this is the following information: page title, search term (through which the visitor came upon the website) search engine, page URL, number of sites visited, visitor’s location (country, region), provider, browser, operating system, screen resolution, browser plugins, visit times, visit duration, entry page, exit page, downloads, referring websites.

The stored data are only analysed for statistical purposes. It is not disclosed to third parties. If users have activated a “Do not track” option in their browser, then Piwik does not store any data on these users.

Request, storage, and use of personal data
If personal data are requested on this website, this is always done openly and voluntarily by the user. Data is only requested if it is necessary. We treat the data as confidential, and only use it within the framework of data protection law for the purposes for which it was collected. Moreover, it is stored in anonymised form for statistical purposes.

6. Right to information

As a user of the website provided by VDI ZRE, you have the right under Sections 19-20 of the Federal Data Protection Act to receive information at any time on the nature and extent of storage connected to your visit to the website. The information is provided to you without charge on request, according to your interest concerning such information.

7. Legal effect of this disclaimer

This disclaimer is considered an integral part of the website on which a link to this page is provided. If parts or individual statements in this text do not, no longer or do not fully conform to the current legal situation, the remaining parts of the document shall not be affected in terms of content and validity.
