The terms transition town, transition initiative and transition model refer to grassroot community projects that aim to increase self-sufficiency to reduce the potential effects of peak oil,climate destruction, and economic instability. The Transition Network, founded in 2006, inspired the creation of many of the projects. A number of the groups have officially registered with the organisation. The first initiative to use the name was Transition Town Totnes, located in the United Kingdom. Transition initiatives have been started in locations around the world, with many located in the United Kingdom, Europe, North America and Australia.
The term, "transition town" was coined by Louise Rooney and Catherine Dunne.
The transition model can be applied to different types of places where people live, such as villages, regions, islands and towns. The generic term is "transition initiative", which includes transition neighborhoods, communities, and cities, although "transition town" is in common usage.
In 2004, permaculture designer Rob Hopkins set his students at Kinsale Further Education College the task of applying permaculture principles to the concept of peak oil. The output of this student project was the ‘Kinsale Energy Descent Action Plan'.
This looked at across-the-board creative adaptations in the realms of energy production, health, education, economy and agriculture as a "road map" to a sustainable future for the town. Two of his students, Louise Rooney and Catherine Dunne, developed the Transition towns concept. They then presented their ideas to Kinsale Town Council. The councilors decided to adopt the plan and work towards energy independence.
Hopkins moved to his hometown of Totnes, England, where he and Naresh Giangrande developed these concepts into the transition model. In 2006 Transition Town Totnes become the first Transition initiative.
Between late 2006 and early 2007 the Transition Network was founded as a UK charity by British permaculture educator Rob Hopkins. It trains and supports people involved with Transition initiatives. It disseminates the concepts of transition towns.
In 2008 the number of communities involved in the project had increased with many localities in the process of becoming "official" Transition towns.
