WHY IT EXISTS

Why This Tool Exists

The Problem

Construction teams manage cost and carbon separately, making it difficult to optimize for both sustainability and budget. Manual carbon tracking adds hours of additional work, and teams lack visibility into the embodied carbon impact of design and material choices.

The Solution

Sterling integrates cost estimating and carbon accounting in a single platform, aligning budget with carbon footprint through shared resources and pricing data. Teams can quickly identify lower-carbon material alternatives and track ESG compliance throughout the project lifecycle.
