For tomorrow to be whole, we have to start with ha/f.




Nearly half of global emissions come from the built environment.

Each choice we make in this realm has an outsized impact on our shared future.

We established Ha/f to work with designers, builders, and policy makers to halve these emissions — this decade.

This isn’t about less.

It’s about rethinking what we build, how we build it, and why.

Ha/f blends design thinking with deep technical knowledge to deliver practical, scalable strategies.

Ha/f the emissions, ha/f the costs, in ha/f the time.

Ha/f is more.
