Should building projects be required to report and limit their total CO2 emissions?
Architecture firm HENN released CarbonBudget, a free digital tool that determines if individual European building projects remain within the 1.5°C global warming limit. The platform enables users to convert abstract climate thresholds into quantifiable project data.
Why it matters
The tool addresses the construction sector's significant environmental footprint by offering a practical method to audit emissions against specific CO2 budgets. This allows operators to align development projects with climate targets while accounting for societal follow-on costs.
The tool relies on data from the Science Based Targets initiative and the Carbon Risk Real Estate Monitor to measure performance against the 1.5°C global warming target. It further incorporates figures from the German Federal Environment Agency to calculate societal follow-on costs.
The players
HENN
An architecture and design firm that develops large-scale international building projects and research-based planning software.
The details
Users input project-specific variables, including geographic location, building area, and completion year, into the software. The system then performs a life cycle assessment, comparing the project's projected CO2 output against an allocated budget to determine environmental feasibility.

October 7, 2026: HENN launched the CarbonBudget tool.
Market Landscape
This tool follows a growing industry pattern of translating the 1.5°C Paris Agreement target into site-specific architectural requirements. It signals a move toward standardizing emissions accounting across the European construction sector.
Architecture and development firms should integrate these CO2 budget calculations into early-stage planning to manage long-term climate risk and social cost projections. Operators can access the software at the official CarbonBudget tool access portal.
The takeaway
The construction industry is shifting toward data-driven emissions management to stay within globally recognized climate boundaries. Designers should monitor how these budget-based metrics influence client demand for sustainable building materials and energy-efficient designs.
