Who we are

Our website address is:

We are a Consortium of organizations led by the Potsdam Institute for Climate Impact Research

This website has been created by Chatham House, the Royal Institute of International Affairs,  an independent policy institute based in London. Our mission is to help build a sustainably secure, prosperous and just world.

Chatham House is comprised of both a charity and a trading company. In this policy wherever you see the words ‘we’, ‘us’ or ‘our’, it refers to both our charity and/or our trading company.

Our trading company is wholly owned and controlled by our charity. Any information we collect may be used by both our entities. Our trading company exists as a separate legal entity so that we can hold our conferences and provide some limited consulting services.

  • Chatham House (The Royal Institute of International Affairs), registered charity no. 208223. Our main trading address is 10 St James’s Square, London SW1Y 4LE. Our VAT number is 653 2181 53.
  • Chatham House Enterprises Limited, registered company no. 2979061. Our main trading address is 10 St James’s Square, London SW1Y 4LE. Our VAT number is 653 2181 53.

Both our charity and our trading company are registered as data controllers with the Information Commissioners’ Office under the Data Protection Act 1998:

  • Chatham House Enterprises Limited: registration number Z1808673.

We take great care to comply with the requirements of the UK Data Protection Act 2018 (“The Act”), the Privacy and Electronic Communications Regulation 2003 and the General Data Protection Regulation 2018, all relating to the personal information you supply to us.

Who we share your data with

We may share your personal information to any member of the Chatham House group, which means our subsidiaries, our ultimate holding company and its subsidiaries, as defined in section 736 of the UK Companies Act 1985.

We may also share your Personal Information with third parties in the following circumstances:

  • In the event that we sell or buy any business or assets, in which case we may disclose your Personal Data to the prospective seller or buyer of such business or assets. In that event, we will attempt to notify you prior to the event and offer you the chance to cease use of the Services and remove your information from our database where we are able to contact you and you require its deletion. In any event, we will endeavour to ensure that your rights and freedoms in respect of the processing of your personal data are adequately and appropriately protected
  • If we or substantially all of our assets are acquired by a third party, in which case Personal Data held by us about you will be one of the transferred assets
  • If we are under a duty to disclose or share your personal data in order to comply with any legal obligation, or in order to enforce or apply our terms of use and other agreements; or to protect the rights, property, or safety of Chatham House (The Royal Institute of International Affairs), our customers, or others. This includes exchanging information with other companies and organisations for the purposes of terrorism, fraud protection and credit risk reduction
  • When acting as agents and data processors carrying out work on our behalf such as fulfilment companies, event partners or program funders. Where we enter into a relationship with an external party, any such arrangements will be subject to a formal agreement between Chatham House and that organization to protect the security of your data
  • When working with partners to deliver an online or physical event, registration details may be shared with event partners for the purposes of monitoring attendance.

The Purposes of transfer of your Data (save in the case of Sensitive Data, where we will have obtained your specific consent to do so for one or more of the Purposes) are lawful because it is necessary for us to hold and use your Personal Data so that we can perform our obligations under the contract we have entered into with you for the Purpose(s).

In the event of any of the above scenarios occurring, we will endeavour to ensure that your rights and freedoms in respect of the processing of your personal data are adequately and appropriately protected.

We will not sell your data to any third party.

How long we retain your data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognise and approve any follow-up comments automatically instead of holding them in a moderation queue.

For users that register on our website (if any), we also store the personal information they provide in their user profile. All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

What rights you have over your data

Our Site may, from time to time, contain links to and from external websites. If you follow a link to any of these websites, please note that these websites have their own privacy policies and that we do not accept any responsibility or liability for these policies. Please check these policies before you submit any personal data to these websites.

If you have an account on this site, or have left comments, you can request to receive an exported file of the personal data we hold about you, including any data you have provided to us. You can also request that we erase any personal data we hold about you. This does not include any data we are obliged to keep for administrative, legal, or security purposes.

You have the right to request a copy of your Personal Data by making a ‘subject access request’ under The Act and to have any inaccuracies corrected.

You also have the following rights:

  • to request us to erase your Personal Data
  • to request us to restrict our processing of your Personal Data
  • to object to the way in which we are dealing with and processing your Personal Information.

Should you wish to exercise these rights, we will require you to prove your identity with two pieces of approved identification. Please address requests to the Data Protection Officer, Chatham House, 10 St James’s Square, London SW1Y 4LE and we will respond within thirty days of receipt of your written request and confirmed ID.

Alternatively, you can log a request directly using our online Chatham House Subject Access Request Form

Please provide as much information as possible about the nature of your contact with us to help us locate your records.

To exercise any of these rights, you should contact our Data Protection Officer at the above address.

If you are not happy about the way in which we have processed or dealt with your information, you can complain to the Information Commissioner’s Office (ICO). You have the right to complain to the Information Commissioner’s Office if you think there is a problem with the way we handle your data.

Where we send your data

Visitor comments may be checked through an automated spam detection service.

We aim to ensure that there are appropriate physical, technical and managerial controls in place to protect your Data. Within Chatham House offices, all of our staff receive training on handling data security.

Where we use external companies to collect or process data on our behalf, your Data may be transferred to, and stored at, a destination outside the European Economic Area (“EEA“). It may also be processed by staff operating outside the EEA who work for us or for one of our suppliers. Such staff may be engaged in, among other things, the provision of support services.

The purpose for such transfers can be a combination of a number of things: the costs of data storage may be lower in countries based outside the EEA; our support teams may be based there (again, usually for reasons of cost; or one of our subsidiary companies which deal with your Data may be based outside of the EEA.

However, we will meet our obligations under the legislation by ensuring that the information has the same protection as if it were being held within the EEA because our hosting company either benefits from the Privacy Shield or has entered into model EU clauses with any sub-processor it uses and based outside the EEA or has established a set of binding corporate rules with its foreign subsidiaries who are based outside the EEA or the Information Commissioner has made a positive finding of adequacy in relation to the territory in which the sub-processor is based and to which your Data may be transferred .

We will take all steps reasonably necessary to ensure that your Data is treated securely as we do and in accordance with this privacy policy.
