Treading More Lightly 

We are pioneering the use of bio-based, bio-circular materials to transform plant-based waste into shoes that have all the comfort you expect from Crocs. In 2025, we achieved 25% bio-circular materials within our Classic Clogs.* 100% of the bio-circular material sourced for our use in our Classic Clog is certified as ISCC PLUS (mass balance approach). We are continuing to evaluate how bio-circular and other alternative materials can help lower the carbon footprint of our most iconic style (see more below)!

*We source repurposed bio-based waste from other industries to produce bio-circular materials. In 2025, Classic Clogs contained at least 25% bio-circular content, calculated on an annual average (January 2025 - December 2025) using a mass balance approach as certified by ISCC PLUS.

Our simple approach to design and materials means that our most iconic shoe, the Classic Clog already has a low carbon footprint. In 2021 we calculated the carbon footprint of a pair of Classic Clogs as 2.56kg CO2e, using the most conservative material emissions factors at the time*. This is significantly lower than many other shoes. For context, MIT researchers calculate the average footprint for a pair of shoes as 14kg CO2e, according to this study.

Now we're driving it down even further. Our most recent carbon footprint analysis in 2024 established a footprint of 1.92kg CO2e for our Classic Clogs, which is a reduction of 25% from our 2021 baseline^. And we’re not stopping there; we’re working towards a 50% reduction in the carbon footprint of our Classic Clog by 2030.

*Using the Higg Product Module 1.0, these calculations used industry recognized sample sizes, were conducted internally, and represent a cradle-to-grave impact.

^Verified by a third-party Product Carbon Footprint (PCF) conducted by SGS environmental consultancy using primary data from fiscal year 2024, which included the use of 25% repurposed plant-based content in our Croslite™ material.

We ship to our fans all over the world and are making strides to reduce our environmental impact.


The majority of our shoes are packaged in a product polybag, which has an 85% lower carbon footprint than a shoe box.* As of early 2025, all of our primary polybags are now made with 100% recycled content!** 

*This comparative metric was made against a shoebox containing 85% recycled cardboard, 15% market mix cardboard, and weighing 180 grams and calculated using the Higg Materials Sustainability Index (Higg MSI at higg.org) V3.7 developed by the Sustainable Apparel Coalition, a cradle-to-gate material assessment tool that calculates environmental impacts of materials. The calculation was completed in 2024 by Crocs, Inc. and is not verified by a third party.
