Standards and methods for saving carbon dioxide

Sustainability is one of the main topics for Catena-X, thus one use case is dedicated to greenhouse gas emissions. Through software apps and the associated regulations, Catena-X aims to help improve carbon levels across vehicle manufacturing and the supply chain.

Real carbon data

Climate neutrality is on everybody’s lips. Global warming must be limited to well below 2°C. Industry must also make its contribution: carbon emissions must be drastically reduced over the entire product lifecycles.

One approach is the transformation towards alternative drives such as electric, hydrogen or natural gas. Another is the reduction of emissions arising from the production of components and vehicles – right through to their disposal or recycling. Then existing processes and structures also offer potentials for improvement.

As a rule, companies calculate their carbon footprint on the basis of measurements, past experience and assumptions. The industry average is often used for individual products and summed up over the added value. No uniform procedure is defined, while the respective depth of detail varies in complexity. There is no data available to record an entire product lifecycle that reflects the real processes and location factors over the supply chain.

Catena-X wants to change all that. 

Standardised measurements along the value chain are aimed at documenting real carbon data and making it comparable within the automotive industry.



Carbon footprint rules

A uniform methodology that specifies existing standards and procedures is needed to record and compare carbon data. Catena-X describes this in a carbon-specific set of rules, the “Catena-X Product Carbon Footprint Rulebook.” 

All the contents have been developed with stakeholders from technology, industry and associations. Here, the partner is WBCSD, the World Business Council for Sustainable Development, a worldwide business and sustainable development organisation.

Documentation via software apps

By 2023, Catena-X plans to complete the first software apps to enable the precise calculation of carbon emissions from several tiers via the main supplier Tier-1 to the car manufacturer (OEM). An application that is explicitly aimed at SMEs is also being prepared. Registered users will be able to see the most important carbon data in the product range overview. They are also notified of any need for action.

The parts list allows the administration of several suppliers per product and shows the data sources of the actual lifecycle assessment. Information on material origin, specifications and other topics will follow.
