Website cookies

This website does not use tracking cookies such as Google Universal Analytics, because we believe that users should have an easy way to avoid web-based surveillance. This is the reason you do not see a pop-up or other request to accept cookies.

The subscription form for our newsletter has a ‘necessary’ cookie so it can pass details to the third-party server that processes the information you provide. This is a technical requirement of the standard technology we use and does not require consent.


Uncharted is our editorial of ideas on sustainable business. We send articles and other insights that we believe are of value to senior managers in business. We may occasionally invite readers to complete a survey or highlight how our work supports an idea, but we do not treat Uncharted as a sales channel.

We use a service called EmailOctopus to collect your e-mail address and to send out the messages via Amazon’s Simple E-mail Service (SES). We will not sell or give your e-mail address to a third party. You may unsubscribe from the newsletter by clicking on the link included in every e-mail. You may also ask us to take you off the list and delete any data related to you.

Amazon SES gathers statistics on e-mail opens, bounces, etc. We can sometimes tell when a reader clicks a link, for example. SES is less intrusive than other platforms used for e-mail distribution, and Amazon is rigorous in removing spammers.

GDPR Article 17

Article 17 of the GDPR standard sets out a right to erasure, popularly known as the ‘right to be forgotten’. You may contact us at any time to ask that we remove your data from e-mail or other systems.

Rights and distribution

Unless stated otherwise, rights to all content on this web site are owned by the Company and may not be re-distributed without express and prior permission. You may link to any page. However, at our discretion we may ask that links be removed where we believe the association to be harmful to the interests of the Company and / or its clients or partners.
