From construction budget to environmental model: AI to decarbonize infrastructure from the design stage

Turn construction budgets into AI-powered carbon intelligence to measure, compare and reduce embodied carbon from the design stage, before construction begins and key decisions are locked in.

Before the first pour, many of the project's most consequential carbon choices have already been made. Materials, structural solutions, construction processes and supply origins are set during design, yet carbon assessment often arrives only when the design is mature and meaningful change is harder.

WHY THIS "CARBON TOOL" CHALLENGE?

The budget already knows the project. The environmental model often arrives too late.

Construction budgets can contain thousands of items described in free text, while environmental information is spread across different databases and formats. Matching each item to the right emission factor can take weeks of specialist work. Teams need that insight earlier, while they can still compare materials, suppliers, structural solutions and transport distances.

Key benefits

Make carbon a design variable, not a late-stage report.

Measure while decisions are still open

Calculate embodied carbon from the construction budget at design stage, before construction begins.

See where impact is concentrated

Move from the full project to chapters, work units, materials and equipment across lifecycle stages A1-A5.

Compare cost and carbon together

Test alternatives for materials, suppliers, structural solutions and transport distances before committing.

Keep every decision traceable

Retain the environmental source, date, unit conversion, AI confidence score and validation history behind each carbon value.

How NTT DATA helps

01

Budget ingestion and model reconstruction

Carbon Tool imports BC3 or Excel budgets, rebuilds the project hierarchy and converts the economic model into an environmental model without starting again.

02

AI-assisted environmental matching

Semantic matching, contextual analysis, unit conversion and confidence scoring connect free-text construction items with relevant environmental factors. Engineers validate or adjust the recommendations.

03

Carbon hotspot analysis

The tool calculates emissions from the project level down to individual materials and equipment, helping teams locate the elements with the greatest impact across A1-A5.

Modern infrastructure designed with carbon impact in mind, illustrating how sustainability can be integrated into early engineering decisions.

04

Scenario comparison before commitment

Teams can compare cost and carbon as design choices change, turning sustainability into an active design variable rather than a retrospective reporting exercise.

05

Traceable decisions and reporting

Each result retains its environmental source, date, unit conversion, AI confidence score and validation history, supporting reproducible assessment, procurement and sustainability reporting.

Proven impact

Earlier insight. Faster assessment. Decisions teams can defend

Carbon Tool has been developed through collaboration between 3 international companies, combining infrastructure expertise, sustainability knowledge and advanced technology.

Results that matter

From carbon reporting to decision-making

Unlike the traditional approach, where the carbon footprint is assessed after many key decisions have already been made, Carbon Tool enables teams to calculate it from the design stage. This makes carbon a decision variable before construction begins, when changing materials, solutions or processes is still viable.

Weeks to hours

Accelerate carbon-footprint calculations that traditionally require weeks of specialist work.

+1,500 hours per year

Release technical capacity from repetitive environmental matching and recalculation tasks.

A1-A5 integrated into design

Integrate lifecycle carbon assessment directly into infrastructure design.

Cost and carbon in one decision

Compare economic and environmental performance within the same decision-making process.

Design lower-carbon infrastructure while you can still change the design.

Start the conversation that turns existing project information into earlier, traceable carbon decisions.
