Scope 3 Emissions in Wire & Cable: Where Material Suppliers Can Make a Difference

For wire and cable manufacturers, Scope 3 emissions are not just a reporting challenge. Learn how recycled content, bio-based inputs, processing support, and material data can help reduce upstream impact without compromising performance.

For wire and cable manufacturers working to reduce greenhouse gas emissions, some of the most difficult emissions to address occur outside their own operations.

Scope 3 emissions extend across the value chain and can include the emissions associated with purchased materials and other upstream activities. That means the compounds used in wire and cable can become part of a manufacturer’s broader carbon footprint.

But in wire and cable, sustainability cannot override performance.

Cable constructions still have to meet demanding electrical, mechanical, flame, smoke, processing, regulatory, and certification requirements. In many applications, UL recognition and other qualification requirements significantly limit which material changes are practical.

That is why the Scope 3 conversation in wire and cable should not begin with the assumption that every cable needs a different polymer or a new “sustainable” compound.

It should begin with a more practical question:

"How can material suppliers help reduce the impact of the materials already required for the application?"

What Are Scope 3 Emissions in Wire and Cable Manufacturing?

Scope 3 emissions are indirect greenhouse gas emissions that occur across an organization’s value chain.

For cable manufacturers, upstream Scope 3 emissions can include emissions associated with purchased raw materials, compounds, components, transportation, and other goods and services required to manufacture cable.

That makes supplier performance relevant.

When a material supplier reduces the emissions intensity of its own operations, improves manufacturing efficiency, reduces waste, or provides better carbon-related information, those efforts can support customers working to better understand and manage the upstream impact of purchased materials.

Supplier Emissions Matter

One of the most direct ways a material supplier can contribute to a customer’s Scope 3 strategy is by reducing the emissions associated with its own manufacturing operations.

Teknor Apex continues to invest in reducing the environmental impact of our operations.

In our 2025 sustainability reporting, we reported a 28% reduction in Scope 1 and Scope 2 greenhouse gas intensity compared with the 2020 baseline.

Those reductions occur within our operations, but they are relevant to the broader value chain because the materials we manufacture become purchased inputs for our customers.

For cable manufacturers, that makes supplier decarbonization an important part of the Scope 3 discussion.

Material Efficiency Can Be Part of the Strategy

Scope 3 improvement is not only about changing what a compound is made from.

It can also involve using material more efficiently.

Cable engineers are continually balancing wall thickness, overall diameter, flexibility, mechanical performance, processing stability, flame and smoke requirements, cost, and qualification constraints.

In some applications, material development can help evaluate opportunities such as:

  • Reduced wall thickness
  • Smaller overall cable diameter
  • Improved dimensional consistency
  • More efficient material usage
  • Formulations better matched to the performance requirements of the cable

These opportunities are highly application-specific and must be validated at the cable level.

But when a construction can meet its requirements using less material, that can reduce the amount of compound required per finished cable and potentially lower the impact associated with material consumption.

Processing Efficiency and Scrap Reduction Matter Too

A material’s environmental impact does not end when it arrives at the cable plant.

How efficiently that material processes can also affect waste.

Extrusion instability, startup scrap, off-spec production, repeated trials, and processing problems can consume additional material, energy, and manufacturing time.

That is why processing support belongs in the sustainability discussion.

Teknor Apex works with cable manufacturers on material selection, custom formulation, troubleshooting, application development, testing, and processing support.

Depending on the application, that may include opportunities to:

  • Improve extrusion consistency
  • Reduce processing-related scrap
  • Address surface or dimensional issues
  • Optimize formulations for production requirements
  • Improve consistency at commercial line speeds
  • Reduce unnecessary trial-and-error during development and qualification

Sometimes the most practical sustainability improvement is not replacing the material.

It is helping the existing material and manufacturing process work more efficiently together.

Waste Reduction Starts Upstream Too

Reducing waste within the material supply chain is another part of lowering overall environmental impact.

Teknor Apex reported 77% of waste was diverted from landfills in our 2025 sustainability report.

Efforts like waste diversion, process optimization, and operational efficiency help reduce the environmental footprint associated with manufacturing the materials our customers purchase.

For cable manufacturers evaluating suppliers as part of broader Scope 3 strategies, operational sustainability performance can therefore be an important consideration alongside product performance, quality, supply reliability, and technical support.

Better Carbon Data Enables Better Decisions

Reducing Scope 3 emissions starts with understanding where they come from.

That requires better information throughout the supply chain.

The teams responsible for cable design, material selection, procurement, and sustainability reporting may increasingly need information related to:

  • Supplier greenhouse gas emissions
  • Material carbon footprint
  • Manufacturing location
  • Energy use and emissions intensity
  • Waste and operational performance
  • Traceability and supporting documentation

Better data makes it easier to identify where the greatest opportunities exist and where changes may have a meaningful impact.

It also helps engineering, procurement, and sustainability teams evaluate material decisions together rather than treating sustainability as a separate initiative.

Cable Performance and Qualification Remain Non-Negotiable

Any sustainability strategy for wire and cable has to recognize the technical realities of the industry.

Changing a compound can affect:

  • Flame and smoke performance
  • Electrical properties
  • Flexibility and toughness
  • Thermal performance
  • Weatherability
  • Chemical resistance
  • Dimensional stability
  • Extrusion behavior
  • Regulatory compliance
  • UL recognition and other certifications
  • Cable qualification

That means lower-impact material development has to happen within the boundaries of the application.

In some cases, those boundaries may allow significant material changes.

In others, the best opportunities may come from improving processing efficiency, reducing material usage, minimizing scrap, or working with suppliers that are reducing the impact of their own operations.

The right answer depends on the cable construction.

How Can Cable Manufacturers Start Addressing Scope 3 Through Materials?

“Reduce Scope 3 emissions” is a large objective. Evaluating a specific cable construction is much more actionable.

A practical starting point is to ask:

Electrical, mechanical, flame, smoke, regulatory, certification, processing, and durability requirements establish the boundaries for material selection.

Could wall thickness, overall diameter, process consistency, or material usage be optimized?

Are startup scrap, processing instability, repeated trials, or qualification challenges creating avoidable material loss?

Supplier emissions, energy efficiency, waste reduction, and operational sustainability all contribute to the footprint of purchased materials.

Better supplier and material data can help technical, procurement, and sustainability teams make more informed decisions and support Scope 3 reporting.

Start With the Cable Construction

There is no single solution for reducing Scope 3 emissions in wire and cable.

There is a specific cable construction, a set of performance requirements, a manufacturing process, and a sustainability objective.

  • Could the cable use material more efficiently?
  • Could processing improvements reduce scrap?
  • Could supplier emissions reductions lower the impact associated with purchased materials?
  • Could better data improve Scope 3 reporting and material decisions?

Those questions turn a broad sustainability target into a practical engineering and supply-chain discussion.

If reducing Scope 3 emissions is part of your strategy, bring Teknor Apex a wire or cable construction. Our material, application development, and processing teams can help identify where material efficiency, processing improvements, supplier performance, and better data may make a meaningful difference while keeping cable performance and qualification requirements at the center of the discussion.
