A²ZERO Week
June 1 – 7, 2025
Join us for the 5th Annual A2ZERO Week, June 1-7 2025!
In June 2020, the City's plan to achieve a just transition to community-wide carbon neutrality, known as A2ZERO, was unanimously adopted by City Council. Each year, the Office of Sustainability and Innovations organizes A2ZERO Week to commemorate the passing of the plan and to celebrate the work done by the City and our many collaborators in the community.

ORGANIC INDIGO VAT DYE CLASS WITH THE MICHIGAN DYER
June 1, 2025 9:30 – 11:30 a.m. The Get Up Vintage
Indigo is an ancient dye plant containing indigotin, an incredible natural dye compound. When exposed to oxygen, indigotin transforms from green to blue, creating indigo's iconic deep blue color. An organic indigo vat uses organic sugars, like banana peels, to ferment the indigo and achieve the striking blue color. This differs from traditional indigo vats, which can produce harmful fumes. Our organic vat – simply indigo, banana peels, and water – is completely safe to touch and breathe.
Registration and guidelines: $50, attendees may bring 2 pieces of 100% natural fiber clothing or textiles for the dye vat included in the registration fee. Additional pieces can be added to your registration for $10 per piece (must purchase this add-on separately).
