Heroal is one of the world's leading companies in the development, production and distribution of high-quality aluminum system solutions for the building envelope and interior, including win-dows, doors, facades, roller shutters and sun protection. With over 800 employees and two production sites, as well as a proud tradition of more than 140 years, heroal stands for in-novation and quality. The company has firmly anchored sustainable thinking and action in its DNA, and in the process wants to develop a better understanding of its own carbon footprint.

Heroal was looking for a digital and scalable solution for long-term use

Heroal already performed manual carbon accounting for Scope 1 & 2. For Scope 3 and the corresponding collection and analysis of CO₂-emissions along the entire value chain, heroal planned to implement a digital and resilient solution that could be con-tinuously built upon over the next years.

Main Needs

The Tanso software enables efficiency increases through information storage and automation

After Tanso was commissioned, a joint kickoff took place at the headquarters in Verl. Here, the data was reviewed and the structures that would lead to the successful creation of the carbon balance for heroal were discussed. Also, in the focus area of category 3.1 "Purchased Goods", suppliers were catogarized to set the basis for specific analyses. This reflects the basic approach of Tanso, which aims to build a well thought-out structure in the implementation year to ensure a repeatable process. By storing information and automating processes, this can save significant time in subsequent years.

Key Achievements

While the calculation of the company-wide carbon footprint still took 10 weeks in the first balance year, heroal's carbon footprint was successfully quantified in just five weeks in the second year. The time required was thus already reduced by 50% after the first year. With the help of detailed analyses at supplier, product group, and material group level, heroal gained a direct understanding of its carbon footprint.
