Janneke Barten is a councillor in Haarlem and a campaigner for Fossil Free NL. She is also involved in the new economy, such as the donut economy and degrowth. She is interested in the translation of global themes (climate change, fair trade) to the local level. How can you use fewer raw materials at a local level, take steps towards a circular economy, or generate sustainable energy? She published the essay 'Change from the bottom up: our best chance' (in the collection: the ideal donut - over the boundaries of our economy) and the research 'degrowth in practice - local initiatives in Haarlem' (on the website ontgroei.nl).
