Prospect Research

In order to better target our fundraising approaches, we may use data from publically available and respected, third-party sources to assess your charitable interests and whether you may be inclined to donate towards Client Earth. This will help us to use our resources more effectively and ensures that you will not receive unwanted donation requests from us. The kinds of information that we may collect could be employment history, published biographic information, media coverage, previous charitable contributions, hobbies/interests, information associated with your postcode, estimate of age, earnings/assets/net worth etc. And this information will come from publically available sources such as social networks, subscription services, news archives, public databases (e.g., Companies House, property registers and the Charity Commission) as well as respected, third party sources.

Wealth Screening

Wealth screening is where we utilise information provided by yourself and third parties to help better understand your giving capacity and whether you may be interested in providing Client Earth with additional support. We can then tailor any additional fundraising approaches to your specific circumstances and ways in which you can support us. This will help us to reduce the amount of irrelevant approaches to yourself and make our operations more cost effective. To ensure accuracy, we will only wealth screen individuals who donate around £500 a year as this is usually an indicator of greater giving capacity. The information we may use to assess your wealth could include your parliamentary constituency, an estimate of your age, an estimate of the size and composition of your household, information about your interests and hobbies, net worth/ assets, stock/property portfolio etc.

Network mapping

We are grateful for the opportunity to work with individuals, trusts, foundations and companies that can support Client Earth work through introductions to networks and higher-level contributions (usually around £10,000 or more). We utilise network mapping to identify individuals who may also be able to give at the level of our current high-level supporters, who may be willing to develop mutually beneficial relationships and could be approached through our networks. We may also combine information that our networks have provided about you with other information that can be found through publicly available information. Examples of information we could be looking for includes employment history, shareholdings, published biographic information, employment and earnings, philanthropic interests and networks, charitable giving history and motivations and relevant media coverage etc. These will be collected via sources as outlined in the prospect research section above.

Pixel tags

A pixel tag is an invisible tag placed on certain pages of a website, which enables cookies to be downloaded to your browser. Pixel tags register when a particular computer and/or mobile device visits a particular page, allowing a particular user to be identified across various sites, and for targeted adverts to be served to that user across the various websites he/she visits.

Controlling pixel tags: Pixel tags are not stored on your computer or mobile device. If you disable cookies, the pixel tag will only detect an anonymous website visit.

Facebook pixel code: Facebook pixel code is a tracking pixel which matches users anonymously with their Facebook ID, enabling re-marketing, analysis, and reporting of our advertising campaigns. For details on these cookies, please view the Facebook Cookie Policy provided at:

Hashed lists, social media and web advertising

We may share your personal data for the purpose of targeted marketing for our campaigning and fundraising activities through Facebook advertising so that they can determine whether you are a registered account holder with them. Our adverts may then appear when you access Facebook. We may also share your personal data as part of an exclusion list for our ad campaigns, which helps us target new people for ClientEarth, rather than targeting people who have already engaged with us.

When sharing information with Facebook we will upload “hashed” personal information to Facebook Ads Manager.  Facebook then matches the hashed personal data with Facebook profiles on in their database, which will create a Lookalike audience. The process of “hashing” is commonly used in digital advertising to convert directly identifiable personal data to pseudonymous personal data for the purposes of security and privacy during data transfer. The hashed data that we share with social media platforms is deleted after between 15 mins and a few hours (subject to database size) and not used for any other purpose.

We may also use social media platform advertising tools to build audiences matching particular characteristics to serve our advertising campaigns. For example, we might target people who have shown an interest in climate change or deforestation. This targeting is based on pages and/or posts people have previously engaged with on the platform. These tools allow us to inspire new people to engage with our work, and help us spread awareness about the issues facing our planet.

If you wish to prevent this use of your data then you can adjust your settings via the social media site (

The data we send could include your name, email address, telephone number and postal address.

Please note that we may share your personal data in a similar way with other social media platforms without further notification provided we assess any new online platform as having similar functioning to Facebook as well as having the required privacy standards and protocols in place to handle this data. Where the functioning of the new social media platforms or the privacy standards and protocols in place are not sufficiently similar we will notify you of any changes to our privacy policy in this respect.

Using online platforms in this way is the most efficient way for us to reach more people who are likely to take an interest in our work, meaning we use our funds most effectively.

Other Third Party Cookies

We have also included a number of features, which allow our users to share some of our content via Facebook. This does not set a cookie by itself, but if one is present it will read it. Another service we use is provided through MailChimp, which helps us to design email newsletters, share them on social networks and integrate with our other services. ClientEarth doesn’t have direct access to those cookies and the use of those third-party cookies is governed solely by the respective service provider’s Privacy statement.

Storage Time: The cookies are stored for a period of two years unless you clear their cache and the cookies themselves.

Your Individual Rights

You have several individual rights in relation to your personal data that we collect, which we are committed to respecting. In particular, you have the right to:

  • Request a copy of your personal information
  • Request any inaccuracies in your personal information be corrected
  • You may also ask to object or restrict the processing of your personal data and have your personal information erased, where appropriate.

Additionally, where we collect your personal details for sending you newsletters, campaigns or updates related to our work, or requests for donations, you have the right at any time to notify us that you no longer want to receive this information.
