HENN Launches CarbonBudget, a Free Tool for Calculating Project-Specific CO2 Emissions
HENN has introduced CarbonBudget, a complimentary digital resource designed for calculating CO2 budgets tailored to specific building projects, accessible at carbonbudget.eu. This tool assists designers in determining whether their projects in Europe meet the Paris Agreement's 1.5°C goal. With the construction sector responsible for roughly one-third of global CO2 emissions, users can enter details such as location, year of completion, and building size to evaluate emissions compatibility. It also visualizes current life cycle assessment (LCA) data and features a Calculating Climate Cost option based on information from the German Federal Environment Agency. Created by HENN's sustainability team, this tool supports architects, engineers, and policymakers in grasping climate limits. Antonia Piñeiro published it on October 07, 2026.
