VERANTWORTUNG

Willkommen auf Fairnetzt-Hochrhein,

Auf beiden Seiten der Rheingrenze gibt es viele Initiativen, Organisationen, Vereine und auch engagierte Einzelpersonen, welche sich für eine nachhaltige, lebenswerte Zukunft in unserer Region und darüber hinaus einsetzen.

Mit Fairnetzt-Hochrhein.de wollen wir eine Plattform bieten, welche auf lebendige und unkomplizierte Weise es Gruppen aus dem Landkreis Waldshut und aus den Kantonen Aargau und Schaffhausen ermöglicht, Veranstaltungen zu veröffentlichen und andererseits interessierte Menschen erfahren können, was wo stattfindet.

Wir wünschen Euch und uns allen
Ein Gutes Leben und Freude am Abenteuer der Mitgestaltung unserer eigenen Zukunft.

Das Redaktionsteam von Fairnetzt Hochrhein

Dritter Nachhaltigkeitsstammtisch in Dogern

Ziel der Treffen ist, miteinander und voneinander zu lernen, wie man sich in verschiedenen Alltagsbereichen nachhaltiger verhalten kann:
• Einkauf von Dingen des täglichen und langfristigen Bedarfs
• Essen
• Energie sparen und erzeugen
• Unterwegs sein und Reisen, Mobilität
• Informationsaustausch
• …………
Jede*r ist willkommen, sich mit seinen und ihren Fragen und Erfahrungen einzubringen.
Grundidee: wir sind alle in bestimmten Lebensbereichen „Expert*innen“ und können so andere mit unserem Wissen bereichern und bei der Umsetzung im Alltag unterstützen.
