Meet the coalition below

Why we exist

An industry that shapes the planet should hear from the people inheriting it.

Buildings and their materials carry an enormous footprint. Deconstruction and reuse keep that value in circulation instead of in a landfill. Our coalition was built to put young people at the center of that work, with real research, real partnerships, and a real voice in the movement.

A seat at the table

We secure young people a genuine voice alongside the established leaders setting the direction of sustainable building.

Champion deconstruction

We promote careful deconstruction and reuse over demolition, so that buildings give their materials a second life.

Connect the field

We link students and emerging professionals with USGBC, Build Reuse, reuse retailers, ESG professionals, and nonprofits.

Do the real research

Our members build secondary-market valuations for salvaged building materials that make charitable reuse possible.

Educate our peers

We use social media and community outreach to show our generation the everyday benefits of reuse and thoughtful building.

Bring fresh perspective

We carry next-generation thinking into an industry that has long needed younger eyes on its biggest questions.

What the coalition does

We carry the conversation in both directions.

The coalition brings sustainable building and the larger ESG conversation into the members' own spheres of influence, at their high schools and universities. In turn, the members bring back to us the issues that matter most to people their age.

Outreach and education

Beyond research, the coalition builds community. Members spend focused time each day finding, following, and engaging with the people and organizations moving reuse forward, growing an audience for sustainable building one conversation at a time.
