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 transit​ion 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, 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).

Liberated Land Use: Power In The People
June 5, 12 - 1p.m., Virtual
Welcome to Liberated Land Use, where we're imagining a future in which land is not a tool of exclusion, extraction, or inequity, but a partner in justice, belonging, and abundance. Rooted in antiracism, pro-Black and Indigenous principles, and a Just Transition framework, we're making room for transformational change, emboldening you to reclaim the policies and practices that shape your neighborhood, your city, and your life.

In this session, we turn to the question of power inside out, not just asking who holds it or how to get it, but exploring how our relationships with power are formed, fractured, and reimagined. Together, we'll trace the stories we've inherited about power. Stories of control, separation, and scarcity - and compost them into new possibilities rooted in equity, collective care, and shared stewardship. This session invites us to ask: How has power shaped us, and how might we reshape our relationship with it? What does healing look like when it comes to power? How might planning become a practice of collective care rather than a tool of control?
