Short answers on embodied carbon, building energy and carbon rules in construction and real estate. To see them worked out with your project data, book a demo.
Carbonova brings construction site emissions (diesel, generators and power), purchased material quantities and EPDs, and the energy use of operating buildings into CarbonOS, a platform of AI agents. It calculates embodied and operational carbon per project and per asset, compares material and retrofit options by their effect on cost and CO₂, and produces reports with an audit trail back to the invoice or the meter.
They come from two places: operational carbon, from the energy used to heat, cool, light and run buildings, and embodied carbon, from materials, transport and construction work. Together, buildings and construction account for 34% of global CO₂ emissions, and the sector depends on materials such as cement and steel that are responsible for 18% of global emissions (UNEP, 2025). That is why material choices matter as much as building efficiency.
Large companies report under AASB S2, which requires Scope 1, 2 and 3 emissions; Group 2 entities started with reporting periods beginning on or after 1 July 2026, and Scope 3 is where purchased cement and steel sit. On the supply side, cement and steel plants that emit more than 100,000 tCO₂e a year are covered by the Safeguard Mechanism, whose baselines fall by 4.9% a year to 30 June 2030.
Yes. Under the Building Energy Efficiency Disclosure Act 2010, anyone offering office space of 1,000 m² or more for sale, lease or sublease needs a current Building Energy Efficiency Certificate, and its NABERS Energy star rating must appear in the advertising; civil penalties apply for breaches. Because buyers and tenants see the rating before they sign, Carbonova tracks each building’s energy and emissions from meter data and ranks the upgrades that improve them most per dollar.
The supply chain agent collects supplier EPDs and data, and the planning agent compares options for each project, such as blended cements or scrap-based electric arc furnace steel, by cost and CO₂ avoided. The gap can be large: on global average, scrap-based electric arc furnace steel emits 0.69 tCO₂ per tonne, against 2.34 for the blast furnace route (worldsteel, 2025).
Yes. CarbonOS reads purchase and invoice data from ERP systems such as SAP or Oracle, plus energy meters and IoT data from sites and buildings, and keeps for every value the lineage to its source document, a versioned emission factor and a change history, in line with the ISO 14064-3 verification standard. The same dataset serves regulatory filings, ISSB-aligned disclosures, green finance and requests from investors, tenants and customers.
