What exactly is a Realm and how do I exchange it?

  • The Realm is a Complementary Community Currency that is created whenever members of this community convert their national currency at a rate of 1 Realm to £1.
  • When a member creates Realms they are creating an opportunity for the community as a whole. The number of times a Realm can be exchanged for trades is unlimited but it can never be spent outside the locality.This means that the local economy is boosted by keeping money circulating locally.
  • The BioCharCoin is a Complementary Eco Currency that is created whenever members of this community choose to convert their national currency at a rate of 1 BioCharCoin to 1 Kg BioChar. The price of this is currently £1 per Kg but is defined as the current retail price per kg when purchased in quantities of 1 metric Tonne.
  • The Realm is used alongside the BioCharCoin to exchange goods and services between members. Each member is free to choose for themselves the relative percentage of Realms and BioCharCoins that are acceptable for each transaction.
  • Every £ that is converted to BioCharCoins is spent on providing members with opportunities to reduce their carbon emissions. A range of products is available for purchase with BioCharCoins such as GroChar Soil Improver, Seed Compost, All Purpose Compost and Fertiliser. This enables all members of the Realm Exchange to participate in the challenge to make Lancaster District Carbon Neutral for a sustainable and prosperous future.


The Realm Exchange is a financial service provided by Banking on Carbon Ltd and assisted by Transition City Lancaster Volunteers that has been set up to provide support to the idea of a more localised economy inspired by the Transition Towns Movement.
