Measure embodied carbon in minutes

Australia's first comprehensive embodied carbon calculator for civil infrastructure. Built by Chartered Engineers for projects big and small.

Get started

Powering sustainable infrastructure

  • Screenshot of a construction project's pavement layer specifications, showing a table with layers, materials, dimensions, volume, mass, and environmental impact data.

    Measure lifecycle carbon

    Our calculation engine covers the entire embodied carbon lifecycle, modules A to D. Understand the emissions you control, built on a foundation of trusted, Australian data.

  • A digital screenshot of a web page containing a 'Scenario Comparison' with dropdown menus for selecting options, and a 'Bar Chart' comparing embodied carbon emissions (kg CO2e) across construction categories for two scenarios, labeled 'Option T' and 'Option 3'.

    Model reduction scenarios

    Apply intensity benchmarks and set carbon reduction targets. Our scenario modelling allows you to seamlessly test and compare design choices.

  • Screenshot of a report page showing an AI summary and chart with project embodied carbon data, including categories like pavement, utilities, miscellaneous, earthworks, and construction.

    Generate narratives with AI

    Facilitate better decision-making with integrated reporting and analysis. Our AI Assistant provides helpful summaries, checks data inputs, and assists in generating a clear narrative.

Your data, your way

Default Data

Get started instantly with a pre-populated library of Australian-specific emission factors from sources like NABERS and AusLCI.

A carbon tool for all stakeholders

Get started

  • Instantly import your entire project from Civil Site Design. Rapidly compare design options such as pavement materials or pipe types to identify the lowest-carbon solution.

  • Move beyond tools designed for buildings. Use the purpose-built WC3 to generate reports for infrastructure and open space projects.

  • Use WC3 analysis and scenario modelling to demonstrate the value of nature-based solutions to your clients.

  • Set, track, and verify embodied carbon targets across your portfolio. Use a standardised framework to accurately measure your Scope 3 emissions.

Frequently asked questions

  • WC3 is Australia’s first purpose-built, comprehensive embodied carbon calculator for civil infrastructure. Officially recognised on the IS Council’s ISupply directory, WC3 allows you to quantify emodied carbon aligned with EN 17472 and the TfNSW Carbon Databook.

  • WC3 models the complete Cradle-to-Grave lifecycle carbon footprint of your infrastructure asset, with a focus on Upfront carbon - the emissions we can control now.

  • Yes. WC3 is registered with the Infrastructure Sustainability Council, and provides the data required to target IS Rating credits such as Rso-6, Ene-1, and Mat-1. WC3’s calculation engine, data hierarchies, and system boundaries are also aligned with the Decarbonising Infrastructure Delivery Policy and Technical Guidance published by Infrastructure NSW.
