Carbon Curator turns a material takeoff into an embodied-carbon report in real time. Type quantities into the index below and watch total carbon, water, energy and hotspots update as you build.
The material table is the core of the platform. Search, filter by category, and type a quantity directly into any row — carbon, water and energy totals update live, and the row is highlighted the moment it holds a quantity.

A material-level and category-level breakdown of every quantity you've entered, generated live from the table above.
Ranked by absolute contribution to total embodied carbon — review these first when looking for reduction opportunities.
The same entered quantities, priced against both calculation bases — useful for sensitivity-checking a design-stage estimate.
A design-stage decision-support summary assembled automatically from your project data.
Every figure on this page is built from the same three-step calculation, run live for every row in the material index.
Type how much of a material your design uses — kilograms of cement, cubic metres of concrete, square metres of glazing, or any of the other units in the index.
Each material carries a South Asian and an international kg CO₂e-per-unit factor, drawn from ICE, ICMD and regional LCA studies. The calculator multiplies your quantity by whichever basis you've selected.
Every row's carbon, water and energy total is added together in real time to produce the project's total embodied carbon, intensity per m², and hotspot ranking.
This prototype uses a transparent benchmark-index approach covering materials spanning cement & concrete, masonry, earthwork/aggregate, structural metals, timber & engineered boards, glass, finishes & flooring, boards & ceilings, insulation, façade & roofing, plumbing & sanitary, electrical, HVAC & mechanical, external works, and admixtures & chemicals — enough breadth for both residential (house) and commercial building projects. South Asian values are intended as design-stage regional proxies, while international values are benchmark coefficients. Manufacturer-specific EPDs should replace generic values whenever available.
Carbon: Quantity × selected embodied-carbon factor, calculated live for every row as you type. For the supplied ranges, the calculator uses the midpoint as the benchmark factor while preserving the original range in the reference documentation.
Water: Quantity × an embodied/manufacturing-water benchmark (L/unit), modelled from category-level water-to-carbon intensity ratios drawn from typical construction-material patterns. It represents production-stage water use, not the building's operational/potable water demand. Energy: Quantity × an embodied-energy benchmark (MJ/unit), modelled the same way from category-level energy-to-carbon ratios.
Material-level factors vary with manufacturing technology, recycled content, electricity mix, transport, specification and system boundary. Water should not be interpreted as a universal global water-scarcity impact unless the source explicitly reports a water-scarcity method.
Sources to validate against: ICE Database, India Construction Materials Database (ICMD), manufacturer Environmental Product Declarations (EPDs), and Pakistan-specific peer-reviewed LCA studies. The water and energy benchmarks in particular are indicative and should be replaced by product-specific EPD data before use in procurement-grade reporting.
