Petra Carbon Index helps organisations understand the embodied carbon associated with construction projects before detailed carbon assessments are available.
Using project cost, building type and construction information, Petra Carbon Index generates an embodied carbon estimate based on extensive real-project datasets.
Verified by Slattery, Petra Carbon Index is continually refined to reflect current market conditions, construction typologies and material trends. The tool provides a consistent and defensible basis for early-stage planning, comparative analysis and Scope 3 reporting across commercial building portfolios.
