Your California Privacy Rights

Residents of the State of California have the right to request a list of all third parties to which a company conducting business in California has disclosed personal information during the preceding year for direct marketing purposes. In turn, businesses (including the Sierra Club), must respond to such requests unless they have a comprehensive privacy policy that gives residents an Opt-out or Opt-in choice for use of their personal information by third parties for their direct marketing purposes and a cost-free means to exercise that right. This Privacy Policy is intended to provide you a comprehensive overview of how we collect, use and share your information.

Exercising Your CCPA Rights

If you are a California resident, you may exercise your rights or authorize another person to act on your behalf by sending an email to

Please note that we may need to verify your identity before we can fulfill your request. Because we maintain limited personal information about consumers, generally consisting of email marketing subscription information, we will generally verify your identity using your email address.  We will respond to requests using the email address that is associated with the information we maintain.

Links to Other Sites

Our Site may contain links to other sites. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by us. Therefore, we strongly advise you to review the Privacy Policy of these websites. We have no control over, and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.

Data Security

We have used technical and organizational security measures designed to secure your personal information from manipulation, loss, destruction or from being accessed by unauthorized persons. All information you provide to us is stored on our secure servers behind firewalls. The security measures are continually improved and adapted in accordance with the latest technology.

However, data provided that is unencrypted could potentially be viewed by third parties. The secure transmission of information via the Internet (e.g. by email) cannot be guaranteed. Sensitive data should therefore either not be transmitted at all or only via a secure connection (SSL).

Any transmission of personal information is at your own risk. If you access pages and files and are then asked to enter personal data, please note that the transmission of such data via the Internet may not be secure and it may therefore be accessed and manipulated by unauthorized persons.

If a data leak or breach is suspected, all incidents need to be recorded and actioned with a preventative measure within 72 hours. The incident will be escalated internally within our Data Committee and action and remedy will be taken afterwards.

Changes to this Privacy Policy

We may update our Privacy Policy from time to time. Thus, we advise you to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page. These changes are effective immediately, after they are posted on this page.
