This website is owned and operated by the Climate Science Legal Defense Fund (CSLDF), a 501(c)(3) non-profit organization headquartered in New York, New York. For the purposes of this online privacy policy (the “Privacy Policy”), the “CSLDF Site” is the website whose home page is located at

CSLDF is committed to protecting the personal information that you provide and entrust to us when using the CSLDF Site. This Privacy Policy describes how we treat all user data collected by CSLDF during your visit to the CSLDF Site, both technical data that is automatically collected and voluntarily submitted data. CSLDF may occasionally update this Privacy Policy. Any information that you submit after a change has been posted will be subject to the new provisions.

User Data We Collect

We collect two types of user data: (1) technical data that is automatically collected from all visitors to the CSLDF Site (“Automatically Collected Data”); and (2) data that you voluntarily submit to us (described below under “Voluntarily Submitted Data”).

Automatically Collected Data. We automatically collect and store Internet Protocol (“IP”) addresses and domain names of the originating visitor’s computer on our server and may know some information you have previously provided through cookies. (See the section on “Cookies” below for more information.) We also track the number and frequency of hits per page, as well as length of website visit, using IP addresses and/or session cookies. In addition, if you come to the CSLDF Site from a website link, we may also identify the source of that link.

Voluntarily Submitted Data. We may collect and store Voluntarily Submitted Data, including personal data, that you voluntarily provide, such as your name and postal address, phone number, e-mail address, and similar information, and transactional information, such as giving and action-taking history, when you participate in certain activities on the CSLDF Site, including (but not limited to) when you:

  • Make a contribution to support CSLDF;
  • Sign up for our CSLDF newsletter;
  • Send correspondence or place a call through the CSLDF Site;
  • Register online for an event;
  • Post a blog comment;
  • Participate in a CSLDF online petition or survey;
  • Follow CSLDF on Facebook or Twitter; or
  • Participate in any activity that requires your Voluntarily Submitted Data.

Other Collected Data. We also may collect data concerning your use of the CSLDF Site or interest in CSLDF communications such as by using an embedded image in an email in order to track whether you open our email communications and using a URL contained in an email we send to you that enables us to identify that you have taken an action using a webpage. We may use this data for a number of reasons, including taking account of your interests in our work so that you do not have to miss the opportunity for us to inform you about, and offer you the chance to take action concerning, the CSLDF issues you care about most, and in order to simplify the process of your signing petitions and filling out surveys.


We collect some data through the use of cookies. Cookies are alphanumeric identifiers that are transferred to your browser on your computer or device and either stored permanently for future access by the transferor (“Long-term Cookies”) or temporarily to facilitate the transferor’s website analysis and functionality (“Short-term Cookies”) or that are transferred temporarily to your computer’s Random Access Memory (“Session Cookies”).

We may transfer a Long-term Cookie in circumstances in which you are notified prior to the cookie being stored. For example, when you select a “remember” option on the CSLDF Site, a Long-term Cookie will be stored on your browser on your computer or device solely for the purpose of automatically filling in the information you have asked to be remembered.

We may use Session Cookies whenever you visit the CSLDF Site for our website traffic analytics application. Session Cookies last only as long as long as your browser session. They expire when you close your browser and are not permanently stored on your computer or device. We also use Session Cookies in e-mails to our Mailing List.

Some of our website analysis and functionality, such as maps and videos, are provided through third-party functionality and require the use of Short-term Cookies. Some elective, third-party media functionality on the CSLDF Site may also use Cookies. Please see the “Third Parties—Third-Party Functionality” section below.

How We Use the Data We Collect

In addition to the uses described above, we use Automatically Collected Data to identify the source outside the CSLDF site of user traffic (for example, or so that we can evaluate what content is persuading web users to become involved in CSLDF’s work. We use Automatically Collected Data, including IP addresses and/or session or short-term cookies, that indicates which sections of CSLDF Site are most visited so that we can perform website traffic analysis, evaluate the popularity of our different web pages and continue to improve the CSLDF Site. In order to learn which CSLDF website content inspired you to undertake action, we also use the Automatically Collected Data we gather just prior to and in connection with your submission of Voluntarily Submitted Data by joining or contributing to CSLDF or taking action on any CSLDF webpage. Automatically Collected Data also may be associated with the Voluntarily Submitted Data you provide to us to detect security intrusions or certain unlawful activity.

We use your Voluntarily Submitted Data for various purposes:

  • To fulfill the request for which you specifically provided the data, including sharing the data with its intended recipient (for example, delivering a petition from you to the recipient of the petition);
  • To analyze actions taken through our website so that we can learn which issues prompt you to become involved in the fight to protect the scientific endeavor;
  • To periodically communicate with you concerning CSLDF matters, such as delivering to you information and updates on our activities, unless you opt out of receiving such information and updates;
  • To indicate you as the author of any comment you post, including on the CSLDF Site blog, when you opt to identify yourself as the author or when posting such comment requires such identification, and to display any personally identifying or other information you voluntarily include in such comments;
  • To confirm your registration to a CSLDF event;
  • To offer you ways to support CSLDF, including requests for contributions if you have not opted out of receiving such communications;
  • To confirm your contribution to CSLDF;
  • To respond to an inquiry or feedback you have made to CSLDF; and
  • To follow up with you with an email specific to an activity you have participated in or intend to participate in.


In some instances when you voluntarily take an action that uses email functionality, you will be alerted immediately following taking that action that you have opted in to receiving further email communications unless you opt out of receiving such communications by unsubscribing.

The CSLDF Site is hosted by servers in the United States. Accordingly, if you are located outside of the United States, the Voluntarily Submitted Data you provide to us will be transferred to the United States. By submitting your Voluntarily Submitted Data, you consent to its transfer and storage in the United States and its use in accordance with the purposes for which it was originally collected.

We may also from time to time combine your Voluntarily Submitted Data with some publicly available data collected from third parties to improve our services to you and for our own internal marketing, communications, and fundraising purposes.

Third Parties

Third Party Sharing. Generally, we do not share Automatically Submitted Data, Voluntarily Submitted Data or Other Collected Data with third parties. However, we do share such data with those third-party service providers who fulfill your orders or transactions, contact you on our behalf, or facilitate some other aspect of CSLDF activities, services or products, including those third-party service providers who collect, process, store and transmit information we collect on this website on our behalf and those third-party service providers we use to assist us in our fundraising and communications efforts. These service providers have access to your Voluntarily Submitted Data solely for the purpose of providing these services to us on our behalf, and they are contractually prohibited from sharing your Automatically Submitted Data and Voluntarily Submitted Data with other third parties other than subcontractors assisting them in their providing these services to us who also are contractually prohibited from sharing your Automatically Submitted Data and Voluntarily Submitted Data with any other third parties.

We may disclose and use Voluntarily Submitted Data regardless in special circumstances when it is necessary to enforce our User Agreement or this Privacy Policy, or when we, under what we hope to be extraordinary and infrequent circumstances, in good faith, truly believe that the law requires us to disclose your Voluntarily Submitted Data to third parties.

Except as described in this Privacy Policy, we will not share your Voluntarily Submitted Data with any third party unless we first notify you and offer you an appropriate choice to consent to such further use, for example, through an opt-out or opt-in request.

Third-Party Functionality. As discussed in the preceding section, to support certain functions carried out on the CSLDF Site, CSLDF uses third-party service providers. In limited instances with respect to specific optional functions on the CSDLF Site, these third parties may have data collection, use or security procedures that differ from the practices outlined in this Privacy Policy and that may impact users of those optional functions. For example, a third-party service provider may allow us to stream videos through the CSLDF Site on an embedded video player (e.g., the YouTube embedded player) and, by viewing that video on the CSLDF Site, you are actually accessing that service provider’s website and subject to its data collection, use or security procedures. This third party may, for example, transfer a Long-term Cookie to your computer when you use this functionality. Please make sure that you review that third party’s procedures prior to using that optional functionality. In cases where it is not clear that you are using a third party’s functionality (i.e., it is not branded as the functionality of a third party), we will notify you that your use of the functionality is subject to a third party’s data collection, use and security procedures and identify that third party.

Internet Transmission. It is important to note that standard email sent across the internet is unencrypted. Emails that leave the CSLDF system or are sent to the CSLDF from outside the CSLDF system – including the information in those emails and the email addresses – are not necessarily secure.

With your consent, such as when you send emails to or receive emails from CSLDF personnel or you decide to use any CSLDF website email functionality, including engaging in our advocacy communications via email, the information transmitted in those communications, including your email address, will be transmitted across the internet in an unencrypted manner.


In furtherance of its mission, CSLDF forms, works with and joins coalitions of organizations and individuals collectively working on issues related to CSLDF’s missions (“Coalitions”). CSLDF does not share Voluntarily Submitted Data you submit to the CSLDF Site with those Coalitions unless you have opted in to doing so, including by submitting Voluntarily Submitted Data to the Coalition through the CSLDF Site or by taking an action on the CSLDF Site that is specifically designated as an action of the Coalition (unless it states on the website page where you take such action that Voluntarily Submitted Data will not be shared with the Coalition). Once you have opted in to doing so (or have voluntarily submitted information to a Coalition in any manner other than through the CSLDF Site), that information is information you are submitting to the Coalition itself. Unless specifically stated otherwise on the CSLDF Site with respect to a Coalition action or a collection mechanism for a Coalition, this Privacy Policy does not address the treatment of personal information, including Voluntarily Submitted Data, that is submitted to a Coalition. Please contact the Coalition or review the privacy statement on the Coalition’s website, if it has one, to learn about the treatment of the information you provide to a Coalition.

Your Ability to Choose

When you provide us with your Voluntarily Submitted Data on the CSLDF Site, you can let us know that you do not wish to receive our email communications by unsubscribing to email communications, by un-checking or not checking the subscription request box on the form you are completing, by unsubscribing from further email communications of a specific type following receipt of an email of that type, by using our contact us page, or by contacting us via postal mail sent to Webmaster, Climate Science Legal Defense Fund, 435 W. 116th St., Rm. 527, New York, NY 10027.


We do not knowingly collect information from children under the age of 13.


The Voluntarily Submitted Data we collect about you is stored on a secure, password protected server and only authorized personnel have access to your information. We use industry-standard encryption technologies with respect to the receipt and transfer of Voluntarily Submitted Data you submit to us on the CSLDF Site and only authorized personnel have access to your information. Nevertheless, despite our best efforts, no transmission over the Internet and no data storage method can be guaranteed to be 100% secure.
