You may deactivate the cookies you have agreed to at any time, free of charge, using the deactivation methods referred to below.

2. Definitions

Cookies contains information about how you browse the Site while using your device (PC, tablet, smartphone, etc.). They are used to send information to your browser and allow the browser to send back information to the Site (such as a session login ID or your language preferences).

Only the creator of a cookie can access or modify the information in it.

You are hereby informed that cookies may be stored on your device when you visit the Site.

3. Purposes of the cookies

The cookies are used on the Site for various purposes, such as to facilitate your browsing, to offer you customised content, or to compile Site visit statistics.

The Site uses browsing cookies that are essential for using the Site. Their exclusive purpose is to enable technical management of the network and ensure or facilitate electronic communications (detect login errors, identify connection points, etc.).

The Site uses preference cookies to offer you browsing capabilities according to your profile (companies, communities/institutional/journalist) and to allow you to access the Site content more easily. The preference cookies also allow content to be stored as favourites on some of our sites.

The Site also uses authentication cookies, which are essential to allowing you to access your personal space from different sites.

Finally, the Site also uses performance cookies in order to:

  • analyse Site traffic and use so that we can:
  • continually improve your browsing experience, with the end goal of providing you with a Site that is ever-more user-friendly;
  • perform statistical studies;
  • memorise your browser’s display preferences (preferred language, display settings, operating system, etc.) and to adapt the Site layout when you visit it, depending on the hardware and software used by your device to view and browse the Site;
  • implement security measures;
  • to improve the performance of the advertisements displayed on the Site;

4. What cookies are used on the Site?

The cookies used on the Site include:

  • ADEME cookies;
  • third-party cookies restrictively chosen by ADEME in order to achieve specific objectives.

ADEME uses third-party services to allow to provide certain Site features so that you can share Site content with other people, allow others to see what pages you have viewed, or to share your opinion on some of our Site content.

These features include social media share buttons (Twitter, YouTube, etc.).

These features rely on third-party cookies, which are placed directly by the social media networks and any other third-party providers that may be involved.

The social network may identify you through the share button, even if you did not use it when browsing our Site. This type of application button may allow the social network in question to track your browsing habits on our Site simply due to the fact that your social media account was activated on your browser (you were logged in to an open session) while you browsed on our Site.

We have no control over the processes used by social networks to collect information on your browsing habits on our Site and on the personal data in their possession. We recommend that you read the terms of use of your data on these social networks to understand the purposes of their use, including any advertising purposes, and the browsing information that may be collected via these application buttons. You should ensure that the terms of use of these social networks allow you to control and restrict the use of your personal data by these social networks, in particular by adjusting your user account settings on these sites.

5. Sharing your device with other people

If your device is used by other people, and whenever a device has multiple browsers, we cannot guarantee that the services and advertisements intended for your device will match your own browsing habits on the device and not those of another user of the same device.

You are solely responsible for any decision to share your device with other people and to allow others to adjust your cookies settings in your browser.

6. Consent

The first time you visit the Site, you will be asked to accept or block the use of certain cookies.

If you do not want cookies to be installed or read on your device, a refusal cookie will be placed on your device so that ADEME can record the information that you do not consent to the use of cookies.  If you delete the refusal cookie, you will no longer be recognised as having refused the use of cookies.

Similarly, when you accept the use of cookies, a consent cookie will be installed.

Consent or refusal cookies must stay on your device. You can adjust your preferences at any time directly on the Site by clicking “Cookie Preferences” at the bottom of the page.

Therefore, if you delete or deactivate all the cookies on your device or if you change devices, we will no longer be able to identify you as having selected this option.

A module allows you to select which cookies you want to allow and which you want to block on the Site.

You can access the module and adjust your preferences by clicking “Cookies Preferences” in the footer of the Site.
