In the picturesque Chiemgau region of Bavaria, a unique local currency known as the “Chiemgauer” is quietly making a significant impact, not just on the local economy but also on carbon emissions. What began over two decades ago as an economics classroom experiment has evolved into a sophisticated micro financial system that now actively promotes environmental sustainability.
From Classroom Project to Regional Staple
The Chiemgauer was launched in 2003 by Christian Gelleri, an economics teacher at a local high school, and his students. Their objective was to counteract the decline of local businesses facing competition from large shopping malls and national chains. The solution was to create a complementary currency designed to keep money circulating within the Chiemgau region. Initially printed by the students, the concept gained traction, and the Chiemgauer gradually transformed from a classroom idea into a functioning financial system.
Today, the association Gelleri still heads, Chiemgauer e.V., manages the currency. Approximately five million Chiemgauers are spent annually, with one Chiemgauer equivalent to one Euro. The banknotes, now professionally printed with anti-counterfeiting features, are a common sight in local bakeries and bookshops, with an estimated 10% to 15% of customers using them. While printing non-euro currencies can be a criminal offense in Germany, the Bundesbank tolerates the Chiemgauer due to its regional confinement and limited user base of around 4,200 individuals and 300 businesses.
Incentivizing Local Circulation and Environmental Action
The Chiemgauer’s operational mechanism is designed to encourage continuous local spending. To keep a Chiemgauer banknote valid, holders must purchase a small stamp every six months, with the cost varying by denomination. For instance, a stamp for a 10-Chiemgauer note costs about €0.30. After three years, the notes expire entirely. While private users cannot convert Chiemgauers back to Euros, businesses can, but they incur a 5% fee. This fee is then reinvested into the currency’s operations and distributed to local non-profit organizations.
The system fosters a circular economy within the region. As one organic food store owner explained, he uses his Chiemgauer earnings to purchase goods from local suppliers, ensuring the money continues to circulate. Similarly, a marketplace vendor uses her Chiemgauer earnings to pay her supplier for fresh ingredients, reinforcing the local economic loop.
A New Dimension: Cutting Carbon Emissions
In recent years, the Chiemgauer initiative has integrated a significant environmental component. Residents and businesses can now earn bonus Chiemgauers for adopting climate-friendly behaviors. These rewards, ranging from one to 200 Chiemgauers, are given for actions such as repairing clothing instead of buying new, utilizing car-sharing services, or insulating homes with natural materials.
Christian Gelleri pointed to a set of balcony solar panels that earned their owner 100 Chiemgauers, estimating that these panels will save 11 tons of carbon dioxide over 20 years. This climate bonus scheme operates as a mini emissions trading system, funded by contributions from local residents and businesses to a shared pool for offsetting emissions. For every ton of carbon offset through the fund, an additional nine tons are saved through the incentivized climate-friendly behaviors.
This innovative approach has inspired similar climate bonus schemes in four other German regions. Over the past four years, these initiatives have collectively saved 12,800 tons of CO2, an amount equivalent to the annual emissions of approximately 2,000 German cars, according to independent auditors TÜV Nord. This demonstrates how a localized financial tool can be leveraged to achieve broader environmental goals.
The Chiemgauer is part of a global trend of around 300 “complementary currencies” that operate alongside official national currencies. While most focus on boosting local economies and welfare, they often have the side effect of reducing transport emissions by shortening supply chains, as vendors increasingly purchase locally produced goods. As Ester Barinaga, a researcher at the University of Lund, noted, “Money can be designed. If money is created to reward pro-environmental behaviors, then you’re going to have more people behaving pro-environmentally.” While the Chiemgauer system has limitations, including a relatively small participation rate and potential regulatory scrutiny if it grows significantly, its success offers a compelling model for how local currencies can be intentionally designed to foster both economic resilience and environmental responsibility.
