What’s are the CO2e emissions of Silk?
The carbon footprint of silk ranges from 221.7 kg CO2e per kg (average) to 238.2 kg CO2e per kg (median), making CO2 emissions from silk notably high. These greenhouse gas emissions from silk production are primarily driven by energy-intensive sericulture practices, mulberry cultivation, and the resource-demanding reeling and processing stages.
- Average footprint per kg: 221.7 kgCO2e
- Median footprint per kg: 238.2 kgCO2e
Emissions by Process Step in Silk Production
The footprint of Silk includes emissions from multiple processing stages. The following process steps were identified as carbon hotspots for Silk production:
- Raw Materials And Yarn Formation: 88.6%
- Textile Formation: 5.7%
- Preparation: 1.9%
How Does Silk Compare to Alternatives?
Organic silk production generates 215.5 kg CO2e per kg of material, representing a 2.8% reduction in greenhouse gas emissions compared to conventional production at 221.7 kg CO2e per kg.
- Virgin Silk per kg: 221.7 kgCO2e
- Organic Silk per kg: 215.5 kgCO2e
Silk Water Consumption
Silk water consumption averages 1253.0 m3 per kg for conventional production, while the water footprint Silk per kg drops to 1174.7 m3 for organic methods, demonstrating reduced water usage Silk through sustainable farming practices.
- Average water use per kg: 1253.0 m3
- Median water use per kg: 1288.8 m3

Case study
"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."

Case study
"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."
Strategy & Sustainability at La Sportiva
Case study
"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."

Case study
"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."
Senior Sustainability Manager, The Northface
Case study
"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."
Sustainability at Allbirds
Case study
"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."
