BuildGreen and CarbonTool are two brands under one roof, working at the intersection of technology and sustainability to transform how buildings and organisations measure, manage, and reduce their environmental impact.

BuildGreen is a building lifecycle data platform. We help design teams, developers, and asset managers achieve green building certifications (BREEAM, LEED, WELL, EU Taxonomy) through structured data and intelligent workflows. Our platform turns the assessment process into a permanent, queryable performance database for every building we touch.

CarbonTool is a corporate sustainability reporting platform. We help organisations calculate their carbon footprint across all GHG Protocol scopes, set science-based targets, and produce CSRD-compliant sustainability reports — powered by a comprehensive emission factor database and automated data processing.

Both platforms share a single engineering team and backend infrastructure. You will work on software that directly contributes to decarbonising the built environment — a sector responsible for nearly 40% of global carbon emissions.
