Happy Socks uses materials such as cotton, polyamide, elastane, and Tencel in their products. They have made a commitment to use more recycled or sustainable sourced materials over time, having increased the percentage of these ethical materials to 41% (from 12%) by 2023. They claim to have created a sustainability logo that indicates 60% recycled or sustainably sourced material content within a particular product (aiming for 70% by 2024), however this logo was nowhere to be found on the website.
26% of all cotton used was organic cotton, 70% of whose suppliers are certified according to the Organic Content Standard (OCS), certifications for the rest are not stated. 11% of all cotton was part of the Better Cotton Initiative (BCI). Their kids’ collection has also been made in organic cotton since 2018, blended with polyamide and elastane. They also use recycled polyester and polyamide, such as for their swim shorts line. However, only 30% of the recycled products’ suppliers are Recycled Claim Standard (RCS) certified, and the other 70% have other certifications for which the names are not specified. They claim to, however, require all sustainably sourced materials to be certified through a 3rd party when possible.
They also use Tencel in some products, which is a naturally sourced fibre that is Forest Stewardship Council (FSC) certified, ensuring better management of forests. However, there is very little of this material used in their overall product range.
They are also working on a Material guideline, which once implemented should help them increase the share of sustainable materials each year.
The Restricted Substances List (RSL) list they work with also ensures better ecosystem health, and they also require their suppliers to commit to the regulations set in REACH and to be Oeko-Tex Standard 100 certified; they have claimed to reach 100% of their goods suppliers being certified and strive to maintain this number, and have provided COSH! with proof.
In 2021 Happy Socks calculated and published its data on emissions through their partner Normative. They follow the Greenhouse Gas Protocol’s classification and divide their emissions into 3 scopes – 1 being direct emissions from owned/controlled resources, 2 being indirect emissions from energy purchased and used, and 3 including all other indirect emissions. This brand has joined Amfori BEPI (Business Environmental Performance Initiative), a business association providing tools for members to improve environmental performance in global supply chains. This tool allows them to collect data on 11 environmental performance areas, which helps them calculate their Scope 3 emissions.
During 2021, their total GHG emissions were approximately 14.8K tonnes of CO2, scope 3 emissions contributing the most with 99%. These emissions were mainly caused by purchased goods and services, and upstream transport and distribution. These emissions have decreased by 3.4% compared to 2020, however they are still refining their calculations and improving accuracy of the emissions calculations.
