Carbon Footprint of Insoles

This page provides an in-depth analysis of the carbon footprint of insoles, a critical component in footwear design. Leveraging detailed emissions data, we identify hotspots, patterns, and opportunities to enhance sustainability for insole manufacturing.

What's the Carbon Footprint of Insoles?

What's the Carbon Footprint of Insoles?

On average, a single insole has a carbon footprint of 0.74 kg CO₂e. This value represents the greenhouse gas emissions associated with the production of 212 insoles, with an average mass of 47.08 g per insole. The emissions range from 0.46 to 1.17 kg CO₂e across the product line.
  • Minimum footprint: 0.46 kg CO2e
  • Median footprint: 0.72 kg CO2e
  • Maximum footprint: 1.17 kg CO2e

Carbon Emissions by Process Step in Insoles Production

Each insole's footprint includes emissions from multiple manufacturing stages. The following process steps were identified as carbon hotspots for insoles:
  • Raw Materials 0.10 kg CO₂e
  • Mixing and Preparation 0.03 kg CO₂e
  • Molding and Curing 0.03 kg CO₂e

Key Insights from the Environmental Data on Insoles

Raw Materials Emissions Hotspot

The raw materials phase is the largest contributor to insoles' carbon footprint at 0.10 kg CO₂e per pair. Improving material sourcing and efficiency could reduce this impact.

Manufacturing Process Optimization

Mixing, preparation, molding, and curing collectively account for 0.06 kg CO₂e emissions per insole. Enhancing process efficiency presents an opportunity for footprint reduction.

Lightweight Product Design

With an average mass of only 47.08 g, insoles have a relatively low emissions intensity compared to other footwear components. Maintaining a lightweight design is environmentally advantageous.

Emissions Variability Across Product Line

The emissions range of 0.46 - 1.17 kg CO₂e suggests variability across the insole product line. Understanding drivers of this variation could identify improvement areas.

"Shoes can consist of up to 1500 components. Before Carbonfact, we asked our developers to weigh every single piece but such a manual approach is not scalable. Carbonfact helped us  in deriving rules to overcome data gaps by creating accurate assumptions."

"With Carbonfact we can do full product LCAs on all of our products. Thanks to measuring things early on, we can simulate how a new product is going to have a different impact compared to the current version. For example, one of our new products is expected to decrease its footprint by a fourth just by designing it differently."

"We needed a solution that could handle the complexities of the apparel supply chain, provide year-to-date insights, and support with detailed scenario analyses for our supply chain. For us Carbonfact is not just a Carbon Management Software, but an extension of our sustainability team."

"What's really special about Carbonfact is the way that it can work alongside the VF brands to help identify where there are gaps in our product impact data. But also helping us bridge towards improving that data. So it's much more of a partner to solve the challenges we have."

"The Explorer is, for sure, my favorite feature. I love the ability to look at the breakdown of the carbon footprint per product line, for processes or on a material basis. That's so dynamic that we're able to leverage it in different ways depending on the projects that we're working on or the teams that we're engaging with."

"Carbonfact's offerings, particularly its product-level focus for footwear and apparel, ensures we can both measure our carbon footprint and actively find ways to reduce it. Carbonfact has been instrumental in helping us model different scenarios and make informed decisions that align with our sustainability goals."

"We have moved from spend-based carbon accounting into Carbonfact to prioritize primary data and get more accurate calculations. The main reason for us to choose Carbonfact is that we now not only get our company's total carbon footprint but also break it down for each of our products."
