Your carbon footprint More and more companies want to reduce in order to counteract climate change with various climate protection measures. In this way, tons and tons of dangerous greenhouse gases can be saved. We present you here product and process solutions, with which CO2-Let emissions be reduced for a sustainable, climate-neutral industry.

Igus plain bearings CO2 footprint



CO2 Calculate footprint – who, how, what?

The CO2-Footprint advances under the CSR policy increasingly in the focus of medium-sized companies. In 2024, companies with more than 500 employees must include environmental indicators in the calculation of their 2023 annual reports and also request the indicators from their suppliers. From January 2025, this regulation will already apply to companies with more than 250 employees. But how is the CO2-Footprint actually calculated?

World's first urban bike made from recycled plastic

International standards like that Greenhouse Gas Protocol and the ISO 14064 standard are applicable here. Key figures such as the purchased energy consumed in the form of electricity, heat or cold, the company's own vehicle fleet, and the CO produced on business trips are included as factors2 emissions or purchased products and services. In the following, we present ways of expanding your “climate protection horizon”:

CO2 Gasket footprint down to the gram

07.02.2023 | As a manufacturer of low-friction seals Freudenberg Sealing Technologies live up to their responsibility for climate protection. To this end, the company has developed a method that can be used to determine the CO2 footprint from the manufacture of seals and other components.

How many grams of CO2 are in a seal? And how can already in the construction phase of a component Greenhouse gas balance from production minimize? To answer these questions seriously, Dr. Meike Rinnbauer and Volker Schroiff at Freudenberg Sealing Technologies. For two years they have been working on a way to precisely determine the carbon footprint of their products. Two factors significantly influence the emission balance of a component: the material and the manufacturing process of the seal. The influence of transport, on the other hand, is smaller by orders of magnitude and can therefore initially be ignored.

Reading tip: Measurement technology for hydrogen production 

For determining the greenhouse gas balance of Materials Freudenberg has its own GreenIndex developed. In addition to the climate-relevant emissions, other environmental properties of chemical substances should also be taken into account in order to be able to compare and evaluate materials and processes internally. "We try to avoid toxic precursors as far as possible in order to ensure the occupational safety of our employees and also to take other environmental influences into account," says dr Rinnbauer. Since modern seals often consist of material mixtures, all individual components are taken into account in order not to set any false incentives for the selection of certain materials.

Determination of greenhouse gas potential

To determine the greenhouse gas potential, eng. Global warming potential (GWP), individual material components, Freudenberg Sealing Technologies uses an expert database. This meets the ISO standard 14044 for life cycle assessments. Mean and location-independent GWP values ​​are used for each individual material, regardless of its specific origin. In the future, the experts expect that manufacturer and location-specific parameters will be available along the entire supply chain. "This would also allow us to select material suppliers not only on the basis of costs, quality and availability, but also on the basis of sustainability criteria," says Dr. Rinnbauer. The sum of all GWPs weighted according to material proportions ultimately results in the overall GWP of a seal.

At the same time, the harmfulness of individual material components is checked using the company's own occupational health and safety guidelines and the European Reach chemicals regulation. Depending on the harmfulness class, a penalty factor assigned, ranging from 1 (harmless) to 2 (persistent). The worst individual value determines the factor by which the overall GWP is multiplied. The resulting dimensionless value can then be assigned to a certain sustainability class of the Green Index for the sealing material. The determined index values ​​are then available to the developers in a company-wide materials database.

Example fluororubber materials 

Based on two fluororubber materials (FKM) for industrial seals, the effect resulting from the weighting process is to be presented: The first mixture does not contain any harmful material components and has a greenhouse gas potential of 9,4 kilos of CO2 / kilo of material. The second mixture generates 8,0 kilos of CO2 / kilo of material. However, the mixture contains a hazardous substance that leads to the classification "unsustainable" in the Green Index. Because the lower sustainability is taken into account with a penalty of 1,66, the first mixture performs better in the overall balance.

An example of a polyolefin based seal for fuel cells also shows that a material can also be very sustainable if it contains a persistent catalyst with a low content of 0,08%. How and to what extent sustainability factors should be taken into account beyond the GWP has not yet been finally decided at Freudenberg Sealing Technologies either. "It is important that we do not optimize one-dimensionally," explains Dr. Rinnbauer. "When selecting the material, we also take service life and wear resistance into account, which influence the ecological balance of our customers."

Die for the manufacture of seals expended energy naturally also leads to CO2 emissions if the production plants are not completely supplied by greenhouse gas-neutral sources. The big challenge is to correctly allocate the CO2 emissions that are incurred for this. It is therefore important to know how much energy is actually consumed in individual process steps in relation to weight, volume or surface area.

Based on the company's core processes, a team at the headquarters in Weinheim examined the specific energy consumption and other environmentally relevant parameters such as the amount of technical waste (engineered waste) consisting of processed material. The four core processes examined include material mixing, shaping, coating and post-heating. In terms of material weight, mixing turned out to be about as energy-intensive as shaping and vulcanization. "But we were particularly surprised that reheating consumes almost as much energy as shaping and vulcanization," says Volker Schroiff.

Simmerring and housing part as sample products

To launch the team, the results were transferred to two sample products: a Simmerring FK extension and a housing part polyamide 6.6 with a functional coating for electromagnetic shielding. There were clear differences: in the case of the Simmerring, shaping and vulcanization account for around half of the entire production-related energy consumption. CO 2 emissions could be reduced by a third with an optimized molding process without post-processing. In the case of the housing part, the plastic production requires a significantly higher proportion of around 40% energy, around a tenth is caused by the coating. In the production of polyamide components, too, a significant proportion of the total emissions are attributable to the material and possibly the technical waste.

Overall it shows a clear trend: "The avoidance of waste during production is the greatest lever for manufacturing components in a more climate-friendly manner, as long as we at least still use fossil energy," explains Mr. Schroiff. "Freudenberg Sealing Technologies is already consistently using waste-avoiding production technology. Just by using cold runner injection molding with valve gate, the company already saves around 70 t of waste and emits 600 t less carbon dioxide every year.

Great interest in CO2-Footprint tracking

10.01.2023/XNUMX/XNUMX | the Ecospeed AG can look back on a very good financial year and is planning further growth for 2023. This development is fueled by the industrial business. Very many, especially medium-sized companies are looking for solutions to reduce the CO2-Determine the footprint of your products and processes. 

Ecospeed is owner-managed, has been in business for twenty years and has now reached a critical mass with over 2000 customers that is responsible for Future security stands. The sudden increase in demand here did not come as a complete surprise.

“On January 1, 2024, the scope of the will be extended in the EU CSR policy to companies with more than 500 employees," comments Christoph Hartmann, founder and managing director of Ecospeed AG. "Companies must include environmental indicators in their annual reports for the year 2023 and also request these indicators from their suppliers. A year later, from January 2025, this also applies to companies with 250 or more employees. This means that the industry must deal with this topic. For this task, we offer proven and easy-to-use software for determining the key figures for the CO2-Footprint."

For this reason, the view of the new financial year is consistently positive: “We plan with you at least a hundred new customers from the industry and primarily have in mind medium-sized companies with around 200 to 2000 employees who precisely and easily measure their CO2-Footprint or want to determine the product carbon footprint.”

Ecospeed already has 20 years experience in the field of CO2-Emissions related to climate protection. The company started with applications for buildings and municipalities, before later adding industry. This applies to the product-related calculation of CO2-Footprint and for the emissions of the whole company (Corporate Carbon Footprint / CCF), ie for the CO2Footprint.

The software is according to the standard eco scout certified, which leading German companies such as VW, SAP and TÜV Rheinland have developed in cooperation with the German Federal Ministry for the Environment (BMU), the Federal Environment Agency (UBA) and the Federal Office for the Environment (BAFU) of Switzerland. The software for determining the CO2 footprint is up to date and is constantly being updated. "Of course we also feel the shortage of skilled workers in the IT industry, but we have committed developers in-house and a dense network of certified specialist consultants," reports Mr. Hartmann.

What is meant by a CO?2 Footprint?

The CO2-Footprint is an important tool for sustainable companies to assess their impact on climate change. As a central component of the eco or CO2 balance and reporting on sustainability, the CO2-Footprint, in which areas the most greenhouse gases are released and where the greatest potential for reducing the carbon footprint lies. The CO2 footprint is the result of the calculated emissions that arise through entrepreneurial activity in the business and production processes as well as through the manufactured products themselves.

How can I get my CO2 Calculate footprint?

For your carbon footprint to calculate, you can use various online tools, often referred to as "CO 2 calculator" or "CO calculator". These carbon calculators assess your carbon footprint or carbon footprint based on various aspects of life including energy use, dietary habits, modes of transport and more.

They usually give the result as CO 2 equivalent aus, a measure that takes all different types of greenhouse gas emissions into account and relates them to the effect of CO2. This helps to quantify CO 2 emissions and CO emissions. Some of these tools also offer tips on how to reduce your footprint. The statement that can be drawn from these calculations is a quantified value that represents your personal commitment to climate protection.
