sustainabilityOur commitment to mould making and mechanical engineering

With Siegfried Hofmann GmbH, you have a partner for tool and machine solutions with a view to a sustainable future. We are actively committed to sustainable practices to both protect the environment and provide added value to our customers.

Our ongoing sustainability measures and certifications reflect our commitment to environmentally friendly processes and efficiency improvements: From utilising energy efficient manufacturing technologies to complying with international environmental standards.

Carbon Footprint Calculation for Your Tools

Sustainability matters – and it can be quantified. At your request, we can calculate the carbon footprint of your new tool.

The calculation is based on the
Greenhouse Gas Protocol (GHG),
an internationally established standard for assessing greenhouse gas emissions.
The result: a transparent and traceable carbon footprint
with clearly stated assumptions and system boundaries.

  • Materials, purchased parts & external services: We use a spend-based calculation with emission factors from the Climatiq database rather than relying solely on weight or quantity.
  • Production: We allocate energy consumption based on the actual machine hours worked. The calculation takes into account our use of 100% renewable electricity since 2024 in accordance with the stated accounting method.
  • Transportation: We calculate the emissions from actual transportation activities using emission factors from the Climatiq database and taking the tool weight into account.
  • End of life: A tool consists of approximately 98% steel – a material with well-established recycling processes. The assumptions regarding end-of-life treatment are clearly stated in the calculation.
