7. Request for information via website forms / newsletter / event registration / competition

a) Order of information documents
If you order information materials on our website, this is done in a so-called double opt-in procedure. This means that after sending the form you will receive an e-mail asking you to confirm your order. This confirmation is necessary so that no one can register with foreign e-mail addresses. Only then will you receive an e-mail with the requested documents (download link or by post if selected).

If you choose this option, the data entered in the input mask will be transmitted to us and saved. These data are: First name, last name, e-mail address. At the time of sending the message the following data will also be saved: Date and time.
In this context, the data will not be passed on to third parties.

The legal basis for the processing of the data transmitted in the course of sending an e-mail is the implementation of pre-contractual measures or a contract in accordance with Art. 6 para. 1 sentence 1 lit. b DSGVO or your consent granted to us in accordance with Art. 6 para. 1 sentence 1 lit. a DSGVO.

Your personal data will be deleted as soon as they are no longer required for the purpose of their collection. Continued processing will only take place if it is necessary within the framework of a resulting initiation and processing of a contract or for the fulfilment of resulting contractual purposes.

b) Order of the Newsletter
We send newsletters, e-mails and other electronic notifications containing advertising information (hereinafter “newsletters”) only with the consent of the recipients or a legal permission.

Content of the Newsletter

In the Green City Newsletter we provide information on topics and products from the corporate environment: renewable energies, ecological investments, energy consulting, energy policy and current event information.

Double-Opt-In and logging

The registration to our newsletter is done in a so-called double opt-in procedure. This means that you will receive an e-mail after registration in which you are asked to confirm your registration. This confirmation is necessary so that nobody can register with foreign e-mail addresses. With the confirmation you give us your consent in accordance with Art. 6 Para. 1 S. 1 lit. a DSGVO that we may use your personal data for the purpose of the desired newsletter.

The registrations for the newsletter are logged in order to be able to prove the registration process in accordance with the legal requirements. This includes the storage of the time of registration and confirmation, e-mail address and IP address. Changes to your data stored with MailChimp are also logged.

Use of the dispatch service provider “MailChimp

Newsletters and document orders are sent via “MailChimp”, a newsletter mailing platform of the US provider Rocket Science Group, LLC, 675 Ponce De Leon Ave NE #5000, Atlanta, GA 30308, USA. This distribution is carried out in accordance with Art. 6 Para. 1 S. 1 lit. f DSGVO and serves our legitimate interest in using an effective, secure and user-friendly newsletter system.

The e-mail addresses of our newsletter recipients as well as their further data described in the context of this notice are stored on the servers of MailChimp in the USA.

MailChimp uses this information to send and evaluate the newsletter on our behalf. Furthermore MailChimp may use this data according to its own information to optimize or improve its own services, for example to technically optimize the sending and presentation of the newsletters or for economic purposes to determine from which countries the recipients come. However, MailChimp does not use the data of our newsletter recipients to write to them or pass them on to third parties.

We trust in the reliability and the IT and data security of MailChimp. MailChimp is subject to the US-EU data protection agreement “Privacy Shield” certified and commited to comply the agreement with the EU data protection regulations. A contract for processing orders is concluded with Mailchimp in the form of the “Data Processing Addendum“.

This is a contract in which MailChimp agrees to commit he protection of the data of our users, to process it on our behalf according to its data protection regulations and in particular not to pass it on to third parties. The privacy policy of MailChimp can be viewed here.

Registration data

To subscribe to the newsletter, it is sufficient to enter your e-mail address. Optionally we ask you to enter your name. This information is only used to personalize the newsletter.

Statistical survey and analyses

The newsletters contain a so-called “web-beacon”, i.e. a pixel-sized file which is retrieved from the server of MailChimp when the newsletter is opened. In the context of this retrieval, technical information, such as information about the browser and your system, as well as your IP address and time of retrieval are collected. This information is used for the technical improvement of the services based on the technical data or the target groups and their reading behaviour based on their retrieval locations (which can be determined with the help of the IP address) or the access times.

Statistical surveys also include determining whether the newsletters are opened, when they are opened and which links are clicked. For technical reasons, this information can be assigned to individual newsletter recipients. However, it is neither our ambition nor that of MailChimp to observe individual users. The evaluations serve us much more to recognize the reading habits of our users and to adapt our contents to them or to send different contents according to the interests of our users.


You can cancel the receipt of our newsletter at any time, i.e. revoke your consent. Your consent to receive the newsletter via MailChimp and the statistical analyses will expire at the same time. A separate revocation of the dispatch via MailChimp or the statistical analysis is not possible.

You’ll find a link to cancel the newsletter at the end of each newsletter.

We would also like to draw your attention to the possibility to object to the collection of data for advertising purposes on the website (for the European area).

c) Event Registration

If you register for an event on our website by e-mail, your data will be forwarded to the e-mail address of the Green City employee responsible for the event. The legal basis for the processing of the data is our legitimate interest according to Art. 6 Para. 1 S. 1 lit. f DSGVO or your given consent according to Art. 6 Para. 1 S. 1 lit. a DSGVO.
The data will be used exclusively for processing in relation to this event and will be deleted once the purpose no longer applies.

d) Raffle

When you participate in one of our competitions, we collect the following data as mandatory information from you: Your surname and first name and your e-mail address. We process these data for the purpose of carrying out the competition. For example, we need your e-mail address in order to contact you in case of a win and to be able to request your postal address. The data processing is thus carried out for the fulfilment of a (competition) contract, Art. 6 para. 1 p. 1 lit. b DSGVO.

8. Collection and Evaluation of usage data (Tracking)

a) Google Analytics

Our website uses Google Analytics, a web analysis service of Google Inc. (“Google”). Google Analytics uses “cookies”, which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of our website is usually transferred to a Google server in the USA and stored there. However, with the activation of IP anonymisation on our website (see below), your IP address will be shortened by Google within member states of the European Union or in other contracting states of the Agreement on the European Economic Area before. Only in exceptional cases will the full IP address be transferred to a Google server in the USA and shortened there. On our behalf, Google will use this information to evaluate your use of our website, to compile reports on website activities and to provide us with further services related to website and internet use. The IP address transmitted by your browser within the framework of Google Analytics is not combined with other data from Google.

We have extended the code integrated in our website by the addition of “gat._anonymizeIp();” to ensure anonymous recording of IP addresses.

Google Inc. based in the USA is certified for the US-European data protection agreement “Privacy Shield”, which guarantees compliance with the data protection level applicable in the EU. The processing is carried out in accordance with Art. 6 Para. 1 S. 1 lit. f DSGVO and § 15 Para. 3 TMG on the basis of our legitimate interest in the statistical analysis of user behaviour for optimisation and marketing purposes.

You can object to the above-mentioned tracking using Google Analytics by clicking on the following link. A cookie will then be set to prevent the future collection of your data when you visit our website (so-called opt-out cookie). Click here to deactivate Google Analytics.

You can also prevent the storage of cookies by adjusting your browser software accordingly; however, we would like to point out that in this case you may not be able to use all functions of our website to their full extent.
You can also prevent the collection of data generated by the cookie and related to your use of our website (including your IP address) and transmission to Google and the processing of this data by Google by downloading and installing the browser extension (plugin) available under the following link. You can find more information on data protection at Google Analytics in the Google data protection information.

b) Google Remarketing

Our website uses the functions of Google Analytics Remarketing in conjunction with the cross-device functions of Google AdWords and Google DoubleClick. The provider is Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.
This feature allows you to link the advertising audiences created with Google Analytics Remarketing to the cross-device capabilities of Google AdWords and Google DoubleClick. In this way, interest-based, personalized advertising messages that have been adapted to you on one device (e.g. mobile phone) depending on your previous usage and surfing behavior can also be displayed on another of your devices (e.g. tablet or PC).

If you have given us permission, Google will link your web and app browsing history to your Google Account for this purpose. In this way, the same personalized advertising messages can be displayed on any device that you sign in with your Google Account.

To support this feature, Google Analytics collects authenticated user IDs that are temporarily linked to our Google Analytics data to help us define and create audiences for cross-device advertising.

You can permanently opt-out of cross-device remarketing/targeting by turning off personalized advertising in your Google Account, following this link:

The aggregation of the data collected in your Google Account is based solely on your consent, which you can give or withdraw to Google (Art. 6 para. 1 sentence 1 lit. a DSGVO). In the case of data collection transactions that are not merged into your Google Account (e.g. because you do not have a Google Account or have objected to the merging), the collection of data is based on Art. 6, para. 1, sentence 1, lit. f, DSGVO. The legitimate interest arises from the fact that the website operator has an interest in the anonymised analysis of website visitors for advertising purposes.
Further information and the data protection regulations can be found in the Google data protection declaration at:

c. Hotjar

Our website uses the web analysis service Hotjar of Hotjar Ltd. Hotjar Ltd. is a European company based in Malta (Hotjar Ltd, Level 2, St Julians Business Centre, 3, Elia Zammit Street, St Julians STJ 1000, Malta, Europe, Tel.: +1 (855) 464-6788).
With this tool, movements on the websites where Hotjar is used can be tracked (so-called heat maps). For example, it can be seen how far users scroll and which buttons users click on how often. Furthermore, the tool also makes it possible to obtain feedback directly from the users of the website. Above all, Hotjar’s services can improve the functionality of the Hotjar-based website by making it more user-friendly, more valuable and easier for end users to use.

When using this tool, we pay particular attention to the protection of your personal data. For example, we can only track which buttons are clicked, the course of the mouse, how far it scrolls, the screen size of the device, device type and browser information, geographic location (country only) and the preferred language to display our website. Areas of the websites in which personal data from you or third parties is displayed are automatically hidden by Hotjar and can therefore not be traced at any time. In order to exclude the possibility of direct personal references, IP addresses are only stored and processed anonymously. However, Hotjar uses various third-party services such as Google Analytics and Optimizely. It may therefore be the case that these services collect data that is transmitted by your browser as part of web page requests. These would be cookies or your IP address, for example. In these exceptional cases, this processing is carried out in accordance with Art. 6 para. 1 sentence 1 lit. f DSGVO on the basis of a justified interest in the statistical analysis of user behaviour for optimisation and marketing purposes.

Hotjar offers each user the option of preventing the use of the Hotjar tool by means of a “Do Not Track” header, so that no data about the visit to the respective website is recorded. This is a setting that is supported by all common browsers in current versions. To do this, your browser sends a request to Hotjar to disable tracking for that user. If you use our websites with different browsers/computers, you must set up the “Do Not Track Header” separately for each of these browsers/computers.
When you visit a Hotjar-based website, you can prevent Hotjar from collecting your data at any time by going to our opt-out page and clicking on Deactivate Hotjar.

9. Embedded Videos

a) Youtube

This website uses the YouTube embedding feature to display and play videos from the provider “YouTube”, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA.

This uses the enhanced privacy mode, which, according to the provider, does not initiate the storage of user information until the video(s) is played. If the playback of embedded YouTube videos is started, the provider “YouTube” uses cookies to collect information about user behavior. According to information from “YouTube”, these are used, among other things, to collect video statistics, improve the user experience and prevent abusive behaviour. If you are logged in to Google, your information is associated directly with your account when you click on a video. If you do not want your profile to be associated with YouTube, you must log out before activating the button. Google saves your data (even for users who are not logged in) as usage profiles and evaluates them. Such evaluation is carried out in particular in accordance with Art. 6 Para. 1 S. 1 lit.f DSGVO on the basis of Google’s legitimate interest in the display of personalised advertising, market research and/or needs-based design of its website. You have a right of objection to the creation of these user profiles, whereby you must contact YouTube in order to exercise this right.

Irrespective of any playback of the embedded videos, each time you visit this website a connection to the Google “DoubleClick” network is established, which may trigger further data processing operations without our influence.
Google LLC, based in the United States, is certified under the U.S. European Privacy Shield Agreement, which ensures compliance with the level of data protection applicable in the EU.

Each time you access a page that offers one or more Vimeo video clips, a direct connection is established between your browser and a Vimeo server in the USA. Information about your visit and your IP address is stored there. Through interaction with the Vimeo plugins (e.g. clicking the start button), this information is also transmitted to Vimeo and stored there. The integration of the videos serves to protect our predominantly legitimate interests in the optimal marketing of our offer in accordance with Art. 6 para. 1 sentence 1 lit. f DSGVO.

The Vimeo Privacy Policy, which provides more information about the collection and use of your information by Vimeo, can be found at

In addition, Vimeo calls up the tracker Google Analytics via an iFrame in which the video is called up. This is Vimeo’s own tracking, which we do not have access to. You can stop tracking by Google Analytics by using the deactivation tools that Google offers for some Internet browsers. Furthermore, users can prevent the collection of data generated by Google Analytics and related to their use of the website (including their IP address) to Google and the processing of this data by Google by downloading and installing the browser plugin available at the following link:
