This Roadmap Summary, published in November 2025 as version 1.1, represents the first step among many DBI efforts – including workshops, conferences, and ongoing research – to guide Australia’s building industry decarbonisation.

The document analyses global and Australian emissions trends, noting buildings’ 42 per cent share of worldwide greenhouse gases in 2022, with embodied carbon rising amid delays in net-zero timelines (e.g., 1.5°C pathway to 2076 globally, 2063 in Australia). It proposes a three-phase strategy: operational net-zero by 2030 via electrification and retrofits; embodied carbon cuts of 40 per cent by 2030 and zero by 2040 through material innovation; and full lifecycle neutrality by 2050 with carbon-negative systems. For Australia, it urges accelerated targets (43 per cent reduction by 2030, 62-70 per cent by 2035 from 2005 levels), backed by $80-160 billion in investments, while warning of carbon budget exhaustion by 2028 and emphasising four pillars: clean energy, industrial change, natural sinks, and built environment upgrades.
