Privacy Policy

The protection and safeguarding of personal data are top priorities for us. We therefore stringently comply with the provisions of the EU’s General Data Protection Regulation (GDPR) and Germany’s (new) Federal Data Protection Act (BDSG).

Below, you will find information on the type of data we collect and the purposes for which it is collected.

General privacy policy

You can visit our pages without disclosing any personal information. For the purposes of system security and to improve our services, we log only non-personal access data, such as your anonymised IP address, the date and time of the website access, the volume of data transmitted, notification of successful access, the browser type and version, your operating system, the page from which you came to us (referrer) or the name of the file/page requested; this data is stored in a server log file for a period of six months. Nothing regarding you personally can be inferred from this data.

Privacy policy with respect to cookies

Our website uses cookies. These are small text files that allow specific, user-related information to be logged in the user’s browser while they use the website and make it possible for the user to be recognised if they visit the website again within a year. In particular, cookies make it possible to determine how often pages are visited and by how many people and to analyse people’s usage behaviour, and also to make our pages more user-friendly and make the page contents match the user’s preferences or be optimally rendered on the device they use.

The content management system (CMS) we use, Typo3, uses a so-called session cookie to this end; this is automatically deleted at the latest at the end of a browser session. This cookie identifies a session, i.e. a visit to our website, and is valid for half an hour (cookie name: ‘’).

The CMS Typo3 installs another cookie which is kept beyond the end of a browser session (cookie name: ‘’) and which can be retrieved when the page is visited again. This enables us to track the frequency of use of our website over a period of 13 months.

The web analytics platform we use, Matomo (see below), uses a session cookie ( cookie, cookie name: ‘PIWIK_SESSID’) for page use analysis purposes which remains valid until the browser window is closed.

If you wish to use Matomo’s opt-out function at the bottom of this page to deactivate the recording and analysis of your website visit, a cookie which is valid for two years is installed (cookie name: ‘piwik_ignore’).

If the ‘Do Not Track’ option is activated in your browser, no Matomo cookies will be installed and your website visit will not be registered and analysed by Matomo.

When you first visit our website, a so-called cookie notice appears, bringing your attention to the use of cookies on the website. If you click on ‘Accept cookies’, a cookie which is valid for 12 months will be installed (cookie name: ‘cookieconsent_dismissed’) to prevent the small notice window from being shown again during this time.

If you do not want cookies to be used, you should adjust your Internet browser settings so that cookies are rejected, either generally or for a specified period. Please note that under these circumstances the cookie notice will appear every time you visit one of the pages of our website.

Privacy policy with respect to the web analytics services Matomo and Webalizer

For the purposes of analysing website usage and to optimise its services, the RNE uses the open-source programs Matomo and Webalizer on this website. These make it possible to evaluate website usage – so-called tracking (Matomo) – and statistically process the server log files (Webalizer) in a manner compliant with data privacy regulations. For tracking, Matomo uses temporary cookies – small text components that are saved in the user’s browser – to allow the RNE to perform an exact, however never personally attributable analysis of a given website visit. The legal basis for use of Matomo is Sect. 6 Para. 1 lit. f GDPR.

The user information Matomo collects via its cookies, including the user’s IP address, is stored temporarily on the Council’s server in anonymised form, where it is evaluated and subsequently deleted. It is not used for any other purpose and is not transferred to third parties.

In addition, Matomo respects your browser’s ‘Do Not Track’ option on this website, which you can activate in your browser to prevent the analysis of your website visit. If desired, the usage of cookies can also be prohibited entirely or on a case-by-case basis in the browser settings.

Below, you have the possibility to at any time prohibit the recording and analysis by Matomo of your visit to the website by simply clicking that you do not agree to the storing and usage of your visitor data. To do so, please remove the tick in the box next to the corresponding notice in the paragraph titled ‘Opt out’. In this case, a so-called opt-out cookie will be stored in your browser that prevents Matomo from gathering data on your visit. Please note that the opt-out cookie itself is also removed if you delete your browser’s cookies at some point in the future. If desired, the opt-out choice would need to be reactivated.

In the event that your browser’s ‘Do Not Track’ option is already activated, you will see a corresponding notice rather than the opt-out. There is then no need to opt out as your visit will not be subject to web analytics.

Use of Webalizer

The version of the Webalizer web statistics program we use does not collect its own data. Rather, it analyses data from the log files on the web server. The last three digits of IP addresses are truncated before they are used for the analysis of usage behaviour, making it impossible for your identity to be determined and preserving your anonymity as a user. The anonymised data records are stored on our web server and are analysed exclusively for internal statistical purposes. At no time is this data shared with any third parties.

Opt Out

Privacy Policy with respect to Social Media Plug-ins such as Facebook and Twitter

Social media plug-ins such as the Facebook or Twitter button usually result in the IP address of a visitor to a website immediately being recorded and their online activities being logged by these services. This is the case even if the website visitor does not click on a social media button. The social media buttons on this website feature a system similar to the recognised system Shariff to protect your data. This ensures that there is no direct contact with the chosen social media network until you actively click on a share button.

Changes to this privacy policy

We will update these guidelines from time to time in order to protect your personal data. You should review these guidelines occasionally in order to remain up to date regarding how we protect your data and how we are constantly improving the contents of our website. If we make significant changes to how we collect, use and/or share the personal data made available to us by you, we shall bring this to your attention by means of an unambiguous and clearly visible notice on the website. By using the website, you consent to the conditions of these guidelines regarding the protection of your personal data.

If you have any questions regarding this privacy policy, please contact the controller listed above.

Personal data shall only be collected if voluntarily submitted by you while registering to order informational materials, via the contact form or when using the Sustainability Code database. We use the data provided by you without your specific consent solely to satisfy your enquiry or process your order and in checks initiated by you in the process of generating the Sustainability Code declaration of conformity. No data shall be shared with any third parties without your consent.

The website uses SSL encryption (https) in accordance with Sect. 13 Para. 7 of Germany’s Telemedia Act (TMG). As such, data submitted to the server in a form (log-in, registration, project processing, etc.) is protected to the latest technological standards.

Planned data transmission to third countries

Data is generally not transmitted to third countries. Exceptions to this may arise as a result of a specific legal basis.

Privacy Policy with respect to personal data

Safeguarding personal data

All the available technical and organisational safety measures are applied to ensure that the personal data you provide us with is safeguarded from being accessed by unauthorised third parties. A limited number of employees of the RNE and of the agencies imug and com&on have access to your personal data.

We store your data on secure servers in Germany. Access to the servers is only afforded to a handful of authorised persons who are responsible for overseeing them technically. We take precautions to ensure that your personal data is secure. Your data is diligently protected from loss, destruction, falsification, manipulation and unauthorised access or disclosure.


The personal data collected for the Sustainability Code newsletter is used for newsletter processing purposes. Your data is not shared with any third parties. Your data is not processed or used for the purposes of advice, advertising or market research. Upon submitting your address, you will receive an email containing a link with which to confirm the authenticity of your address and your order. You may cancel your order at any time. If you cancel your subscription, your personal data will be deleted in full.

Use, storage and deletion of personal data

The data you enter into the Sustainability Code database when generating Sustainability Code declarations of conformity is stored on the com&on server and, prior to the declarations being published, is used by the Sustainability Code Office exclusively for communication purposes during the feedback process. This data is not accessible prior to its approval by the Sustainability Code Office and its general publication by the companies reporting in accordance with the Code. The data remains the property of the companies and organisations. Published declarations of conformity are made publicly accessible in the Sustainability Code database on the website

The data you provide during registration is used for the purposes of use of the website. You can be notified by email about information relevant to the website and to registration such as changes to the scope of the website or technical circumstances. The data collected on you is visible in the input mask during registration. Personal data includes your username and password (encrypted), your first name and surname, your email address and your consent to receiving activity information.

Your rights

You have the right to request information about the personal data stored about you, the right to have it amended if desired and the right to limit its processing or demand its deletion.

Insofar as there are no reasons necessitating contract data processing, you may at any time revoke the consent you previously granted to your personal data being stored in writing (e.g. by email or fax) with immediate effect. Your data shall be deleted without undue delay and at the latest within five working days.

The lawfulness of the processing of the data up until the time permission is revoked shall remain unaffected.

To revoke your consent, please send an email to: team(at)

Should you have any questions or complaints regarding this data privacy notice or the processing of your data, please contact the GIZ Data Protection Officer at the following email address: datenschutzbeauftragter(at)

You have the right to address your complaint to the relevant data protection authority. This is the Federal Commissioner for Data Protection and Freedom of Information (BfDI).
