Architects have slashed carbon equal to planting near-200,000 trees so far. The Challenge gives architectural practices the tools to model and improve whole‑of‑life carbon for low‑ to medium‑density homes up to 3 storeys — from new houses to ‘alts+adds’, duplexes, multi‑unit projects and more.
Our mission
Our goal: save carbon equal to 1 million trees planted and we want every state and territory as we push toward net‑zero whole‑of‑life carbon residential targets.
Share this with your architectural community so they can take the Challenge and secure your Chapter’s place in this flagship national initiative.
National visibility, benchmarking and promotion
Every project contributes to a national carbon benchmark that will power the Australian Institute of Architects’ advocacy, research, and promotion.
Your local architects’ work may be shortlisted for the national publication and exhibition launch showcased at the 2026 National Architecture Conference — a huge platform for design leadership.
