III. General information on data processing
Scope of the processing of personal data
We only process personal data of users of our website if this is necessary to provide a functional website as well as our contents and services. The processing of our users' personal data takes place regularly only with their consent. An exception applies in those cases where the processing of the data is permitted by law.
Unless not stated differently in this data protection declaration, your data will not be passed on to third parties. In the performance of its public duties, the German Environment Agency (UBA) transfers personal data in individual cases to other federal public bodies or external contractors for the technical operation, in particular hosting, of the website. The technical service provider named in the imprint acts on behalf of the German Environment Agency on the basis of a contract. In this case, it acts as a processor. Compliance with data protection regulations is guaranteed by the additional contract processing agreement. The service provider is bound by the UBA's instructions and is regularly monitored accordingly. Your data will not be passed on for commercial purposes or to other third parties.
Your data will also not be processed or used for consulting, advertising or market research purposes. The data stored in the website's editorial system can only be viewed by the German Environment Agency's editorial staff of the Division and the external service provider for the technical operation of the website.
All information you send to the German Environment Agency using the online forms on this website is transmitted in encrypted form via a "Secure Socket Layer" (SSL) connection. Your personal data cannot be read by unauthorized persons during transmission on the Internet.
Legal basis for the processing of personal data
The legal basis for the processing of personal data is the consent of the data subject pursuant to Art. 6 para. 1 lit. a of the EU General Data Protection Regulation (GDPR) or one of the following legal provisions:
In the processing of personal data required for the performance of a contract to which the data subject is a party, Art. 6 para. 1 lit. b GDPR serves as the legal basis. This also applies to processing operations that are necessary to carry out pre-contractual measures.
Insofar as the processing of personal data is necessary to fulfil a legal obligation to which we are subject, this obligation serves as the legal basis in accordance with Art. 6 para. 1 lit. c GDPR.
If processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in us, Art. 6 (1) (e) GDPR serves as the legal basis. The legal basis for operating our website is Art. 6 (1) (e) GDPR in conjunction with the UBA Establishment Act as well as Art. 3 of the Federal Data Protection Act (BDSG) and Art. 3 of the eGovG.
Data erasure and storage time
The personal data will be deleted or blocked as soon as the purpose of storage ceases to apply, i.e. a publication ordered has been sent out or a newsletter subscription cancelled.
Furthermore, data may be stored if this has been provided for by the European or national legislator in EU regulations, laws or other provisions to which the person responsible is subject. The data will also be blocked or deleted if a storage period prescribed by the aforementioned standards expires, unless there is a need for further storage of the data for the conclusion or fulfilment of a contract.
IV. Provision of the website and creation of log files
Description and scope of data processing
Every time you visit our website, our system automatically collects data and information from the computer system of the calling computer.
The following data is collected:
- Information about the browser type and version used
- The user's operating system
- The IP address of the user
- Date and time of access
- Websites from which the user's system reaches our website
- Websites accessed by the user's system via our website
- Name of the file retrieved
- Volume of data transmitted
- Notification whether the request was successful
The data is also stored in the log files of our system. This data is not stored together with other personal data of the user.
Legal basis for data processing
The legal basis for the temporary storage of data and log files is Art. 6 (1) e) GDPR in conjunction with the UBA Establishment Act as well as Art. 3 BDSG and Art. 3 eGovG.
Purpose of data processing
The temporary storage of the IP address by the system is necessary to enable the website to be delivered to the user's computer. For this the IP address of the user must remain stored for the duration of the session.
The storage in log files is carried out in order to ensure the functionality of the website and thus to fulfil the task according to Art. 6 Para. 1 e) in conjunction with the UBA Establishment Act as well as Art. 3 BDSG and Art. 3 eGovG.
This data from the log file is not combined with any other stored data, as may arise when other offers are made in connection with the provision of personal data. A direct reference of the IP number from the log file to your person is not possible and is excluded. The IP address is only evaluated in the event of attacks on the German Environment Agency's Internet infrastructure, offences against morality and other illegal activities in connection with the use of the Internet offer. A conclusion from the IP number to your person is only possible through your dial-in provider through a public prosecutor's investigation.
Duration of storage
The data will be deleted as soon as they are no longer necessary to achieve the purpose for which they were collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended.
If the data is stored in log files, this is the case after 14 days at the latest. Further storage is possible. In this case the IP addresses of the users (as far as possible for the purpose) are deleted or alienated, so that an assignment of the calling client is no longer possible.
Possibility of objection and elimination
The collection of data for the provision of the website and the storage of data in log files is absolutely necessary for the operation of the website.
V. E-mail contact
Description and scope of data processing
You can contact us by e-mail at: immission@uba.de In this case, your personal data transmitted with the e-mail will be stored.
In this context, no data will be passed on to third parties without your separate consent. The data will be used exclusively for the processing of the conversation in the Division of the German Environment Agency.
Legal basis for data processing
The legal basis for processing data submitted via the contact form or via e-mail is Art. 6 (1) (e) GDPR in conjunction with the Federal Environment Agency Establishment Act and Art. 3 of the Federal Data Protection Act (BDSG), and Art. 3 of the eGovG.
Purpose of data processing
The processing of the personal data from the input mask or from the e-mail serves us only for the treatment of the establishment of contact. In the event of contact by e-mail, this also constitutes the necessary legitimate interest in the processing of the data.
The other personal data processed during the sending process serve to prevent misuse of the contact form and to ensure the security of our information technology systems.
Duration of storage
Your requests and our answers are stored in electronic files of the German Environment Agency in accordance with the guidelines for the processing and administration of documents in federal ministries. The storage period is up to eleven years.
Possibility of objection and elimination
If you withdraw your consent to data storage, please contact our data protection officer. The data will then be deleted unless we are subject to retention obligations that prevent deletion.
Further information on communication by e-mail
Communication by e-mail can have security gaps. Emails sent to employees of the German Environment Agency can be stopped and read by experienced Internet users. If the German Environment Agency receives an e-mail from you (e.g. via the contact form), it is assumed that we are also entitled to reply by e-mail to this e-mail address. Otherwise we ask you to consider another way of communication (e.g. by post).
Caution with questionable e-mails: Fraudsters repeatedly try to install malware (e.g. viruses and Trojan horses) on foreign PCs via attachments or links in e-mails - by fomenting fears with content such as unpaid invoices or attracting attention with dramatic messages. Mistrust emails with lurid subject lines, dubious content or questionable origin and delete them immediately. Never open attachments or links in such emails. As a general rule, the German Environment Agency never sends files with the suffix".exe″ or".com″ attached. Please do not open such files and inform us best by telephone about such an e-mail. The German Environment Agency will never ask you to send us sensitive data such as bank details or passwords by e-mail or telephone.
VI. Map services
Maps based on the OpenStreetMap map service are available on some subpages of the German Environment Agency website. This is an external service of the OpenStreetMap Foundation (OSMF, United Kingdom). We would like to point out that when you visit these subpages, personal data (browser fine-print, IP address) may be transmitted and cookies may be set on your computer. For more information, please see OSMF's Privacy Notice and OSMF's Privacy FAQ. We would like to point out at this point that the terms of use of the OpenStreetMap service and its operators are not subject to the control of the German Environment Agency.
VII. Your rights
If your personal data are processed, you are affected within the meaning of the basic EU General Data Protection Regulation (GDPR) and you are entitled to the following rights vis-à-vis the person responsible. Please contact the German Environment Agency's Data Protection Commissioner (see above).
Right to information (Art. 15 DSGVO)
You can ask the person in charge to confirm whether personal data concerning you will be processed by us.
If such processing has taken place, you can request the following information from the person responsible:
- the purposes for which the personal data are processed;
- the categories of personal data being processed;
- the recipients or categories of recipients to whom the personal data concerning you have been or are still being disclosed;
- the planned duration of the storage of the personal data concerning you or, if specific information on this is not possible, criteria for determining the storage period;
- the existence of a right to rectification or deletion of personal data concerning you, a right to limitation of processing by the controller or a right to object to such processing;
- the existence of a right of appeal to a supervisory authority;
- any available information on the origin of the data if the personal data are not collected from the data subject;
According to Art. 89 (2) GDPR, this right to information may be restricted to the extent that it is likely to make the realisation of the research or statistical purposes impossible or seriously compromises it and the restriction is necessary to fulfil the research or statistical purposes.
Right to correction (Art. 16 DSGVO)
You have the right to request rectification and/or completion from the data controller if the processed personal data concerning you are incorrect or incomplete. The person responsible shall make the correction without delay.
Your right to rectification may be restricted according to Art. 89 (2) GDPR to the extent that it is likely to make the realization of the research or statistical purposes impossible or seriously compromises it and the restriction is necessary to fulfill the research or statistical purposes.
Right to limitation of processing (Art. 18 DSGVO)
Under the following conditions, you may request that the processing of personal data concerning you be restricted:
- if you dispute the accuracy of the personal data concerning you for a period that enables the data controller to verify the accuracy of the personal data;
- the processing is unlawful and you refuse to delete the personal data and instead request that the use of the personal data be restricted;
- the data controller no longer needs the personal data for the purposes of the processing, but you do need them to assert, exercise or defend legal claims, or
- if you have filed an objection to the processing pursuant to Art. 21 para. 1 GDPR and it has not yet been determined whether the legitimate reasons of the person responsible outweigh your reasons.
If the processing of personal data concerning you has been restricted, this data – apart from being stored– may only be processed with your consent or for the asserting, exercise, or defense of legal claims or to protect the rights of another natural or legal person, or for reasons of important public interest of the Union or a Member State.
If the restriction of processing has been restricted in accordance with the above-mentioned conditions, you will be informed by the person responsible before the restriction is lifted.
Your right to restriction of processing may be restricted in accordance with Art. 89 (2) GDPR to the extent that it is likely to make the realization of the research or statistical purposes impossible or seriously compromises it and the restriction is necessary to fulfill the research or statistical purposes.
Right to cancellation (Art. 17 DSGVO)
a) Duty to delete
You may request the data controller to delete the personal data relating to you without delay and the controller is obliged to delete this data without delay if one of the following reasons applies:
- The personal data concerning you are no longer necessary for the purposes for which they were collected or otherwise processed.
- You revoke your consent, on which the processing was based pursuant to Art. 6 para. 1 lit. a or Art. 9 para. 2 lit. a GDPR, and there is no other legal basis for the processing.
- You file an objection against the processing pursuant to Art. 21 para. 1 GDPR and there are no overriding legitimate reasons for the processing, or you file an objection against the processing pursuant to Art. 21 para. 2 GDPR.
- The personal data concerning you have been processed unlawfully.
The deletion of personal data relating to you is necessary to fulfil a legal obligation under Union law or the law of the Member States to which the data controller is subject.
Reference is made to the restrictions on the obligation to delete data under Section 35 of the Federal Data Protection Act (BDSG).
b) Information to third parties
If the data controller has made the personal data concerning you public and is obliged to delete it pursuant to Art. 17 para. 1 GDPR, he shall take appropriate measures, including technical measures, taking into account the available technology and the implementation costs, to inform data processors who process the personal data that you as the data subject have requested the deletion of all links to this personal data or of copies or replications of this personal data.
Reference is made to the restrictions in Section 35 BDSG.
c) Exceptions
The right to cancellation does not exist insofar as the processing is necessary
- to exercise freedom of expression and information;
- for the performance of a legal obligation required for processing under the law of the Union or of the Member States to which the controller is subject or for the performance of a task in the public interest or in the exercise of official authority conferred on the controller;
- for reasons of public interest in the field of public health pursuant to Art. 9 para. 2 lit. h and i and Art. 9 para. 3 GDPR;
- for archiving purposes in the public interest, scientific or historical research purposes or for statistical purposes pursuant to Art. 89 para. 1 GDPR, insofar as the law referred to under a) is likely to make it impossible or seriously impair the attainment of the objectives of such processing, or
- to assert, exercise or defend legal claims.
d) Right to information
If you have exercised your right to have the data controller correct, delete or limit the processing, he/she is obliged to inform all recipients to whom the personal data concerning you have been disclosed of this correction or deletion of the data or restriction on processing, unless this proves impossible or involves a disproportionate effort.
The person responsible shall have the right to be informed of such recipients.
Right to data transferability (Art. 20 DSGVO)
You have the right to receive the personal data concerning you that you have provided to the person responsible in a structured, common and machine-readable format. In addition, you have the right to pass this data on to another person in charge without obstruction by the person in charge to whom the personal data was provided, provided that
- processing is based on consent pursuant to Art. 6 para. 1 lit. a GDPR or Art. 9 para. 2 lit. a DSGVO or on a contract pursuant to Art. 6 para. 1 lit. b GDPR and
- processing is carried out by means of automated methods.
In exercising this right, you also have the right to request that the personal data concerning you be transferred directly from one data controller to another data controller, insofar as this is technically feasible. The freedoms and rights of other persons must not be affected by this.
The right to data transferability does not apply to the processing of personal data necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller. However, according to Article 20 (3) Sentence 2 GDPR, this right does not apply if the data processing serves the performance of public tasks.
Right of objection (Art. 21 DSGVO)
You have the right to object at any time for reasons arising from your particular situation to the processing of your personal data in accordance with Art. 6 para. 1 lit. e or f GDPR.
The data controller no longer processes the personal data concerning you, unless he can prove compelling reasons worthy of protection for the processing, which outweigh your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims.
You have the possibility to exercise your right of objection in connection with the use of Information Society services by means of automated procedures using technical specifications, notwithstanding Directive 2002/58/EC.
You also have the right to object to the processing of personal data concerning you for scientific or historical research purposes or for statistical purposes pursuant to Art. 89 para. 1 GDPR for reasons arising from your particular situation.
Your right of objection may be restricted to the extent that it is likely to make the realization of the research or statistical purposes impossible or seriously compromises it, and the restriction is necessary to fulfill the research or statistical purposes. According to Art. 36 of the Federal Data Protection Act (BDSG), this right does not apply to a public authority if there is a compelling public interest in the processing that outweighs the interests of the data subject, or if a legal provision requires the processing.
Right to revoke the data protection declaration of consent (Art. 7 DSGVO)
You have the right to revoke your data protection declaration of consent at any time. The revocation of consent shall not affect the legality of the processing carried out on the basis of the consent until revocation.
Right of appeal to a supervisory authority (Art. 77 DSGVO)
Without prejudice to any other administrative or judicial remedy, you have the right of appeal to a supervisory authority, in particular in the Member State where you reside, work or suspect of infringement, if you believe that the processing of personal data concerning you is contrary to the GDPR.
The supervisory authority to which the complaint has been lodged shall inform the complainant of the status and results of the complaint, including the possibility of a judicial remedy under Article 78 GDPR.
In the case of the German Environment Agency, the responsible supervisory authority is the Bundesbeauftragte für den Datenschutz und die Informationsfreiheit (Federal Commissioner for Data Protection and Freedom of Information). You can contact the Federal Commissioner for Data Protection and Freedom of Information at poststelle@bfdi.bund.de, www.bfdi.de, Graurheindorfer Str. 153, 53117 Bonn, Tel. 0228/997799-0.
