Our ambition to make the world a happier and more colorful place is not sustainable unless we are. It’s time for the fashion industry to change, and we have a part to play.
We are committed to constantly making improvements towards better sustainability in every aspect of what we do. This planet is a pretty great place after all, let’s keep it that way.
These are our main sustainability goals.
)
As of the first quarter of 2025, Happy Socks now exclusively uses more sustainably sourced cotton.
Our first goal focuses on cotton since it is the main material that we use, due to its great qualities and durability. Unfortunately, completely sustainable cotton doesn’t exist, but there are more sustainable cotton options. The cotton considered to be more sustainable has a certification such as certified organic cotton (OCS) and recycled cotton (RCS), or cotton with the Better Cotton trademark.
)
For us that means materials that are secured by a recognized reliable third party through certifications and trademarks.
In FY 2024/25, 61% of the material that we used were recycled or more sustainably sourced, a number that grows by the year, and that we aim to keep growing until we reach 100%!
Right now we use OCS-certified organic cotton, Better Cotton*, Tencel™ Modal, RCS-certified recycled polyamide, RCS-certified recycled polyester and RWS-certified wool. We’re constantly on the lookout for new, sustainable materials to use in our products!
*Percentage Better Cotton from total amount of conventional cotton, calculated from the volume of cotton lint according to BCI standard calculation methods.
)
This goal focuses on all types of emissions, be it from material production, manufacturing socks, transports, marketing products, retail stores and so on.
As it stands, we are well on track and have already seen significant reductions. We are continuously improving our way of measuring and working.
Renewable energy
Renewable energy is key for lowering our emissions. The vast majority of greenhouse gas emissions from all sectors come from the burning of fossil fuels, such as coal, oil, and natural gas.
In 2024, we used 49% renewable energy in our production, while 36% of the energy in our retail stores and offices were renewable. We are committed to the goal of having all our energy be renewable before 2030.
*Compared to the starting year 2020.
Why “more”? Because there are no sustainable materials, only better or worse, and we keep searching for the best options for our products.

Organic Cotton
Since 2018, our kids’ range has been made from organic cotton. Some of our adult styles are made from organic cotton too, such as our classic collection, solid socks and most of our collaborations.
Better Cotton
We joined Better Cotton in 2021. Together, we are committed to improving cotton farming practices globally. The percentage of Better Cotton in our socks is increasing every year. Read more about our work and the percentage of Better Cotton in our Impact Report.
Recycled Cotton
Old is the new new! Curiosity is at our core, and we keep testing new ways of working. In 2023, we introduced our first gift set containing socks made from a recycled cotton blend.
)
TENCEL™ Modal
In 2022, we introduced a new material to our socks: TENCEL™ Modal. It’s made from wood converted into a fiber by dissolving it in a nontoxic solvent and then spinning it into yarn. Compared to conventional cotton, TENCEL™ Modal has a lower environmental impact because it requires less water and energy to produce and the solvent is recycled and reused, resulting in minimal waste and emissions.
)
Recycled Polyamide
All our kids’ socks are made from both organic cotton and recycled polyamide: a light and durable material that has been diverted from becoming waste and given a second life.
Recycled Polyester
We also use some recycled polyester, which is a similarly light and durable material that requires less energy to produce and with lower CO2 emissions, compared to virgin polyester.
)
We’ve removed plastic windows from gift sets, and mailer bags are now made from recycled plastic.
In 2020, we removed plastic hooks from the kids’ range and in 2023 we removed them altogether, to be replaced by a new paper hook on the label instead. That’s a lot less plastic.

We are on track
We have set ourselves some ambitious goals when it comes to transforming our business to be more sustainable. The good news is that we are on track to reaching these goals. Every increase in the percentage of recycled or sustainably sourced materials helps us towards becoming a more responsible company. In 2024/25 we made progress on that journey. While each of these changes in itself is relatively small, together they help us maintain our momentum towards sustainability.
Cutting our emissions in half
We set the goal to reduce our carbon emissions by 50% before 2030*. Since 2023, Happy Socks has been part of Science Based Targets initiative (SBTi) and has therefore made a promise to have targets that are in line with the latest climate science and ambitious enough to limit global warming to no more than 1.5°C above pre-industrial levels.

Carbon footprints for all our products
In 2023, we teamed up with Carbonfact and began calculating the carbon footprints for all our products. This means that we have improved our emissions-calculation measuring method, and have moved from spend-based emissions calculations to action-based emissions calculations. We have also increased the scope and are now calculating the total footprint of all our products with the help of the Carbonfact LCA (life cycle assessment) method.
We continue to reduce our use of plastic
We are continuously working toward using less plastic. In 2020, all plastic hooks were removed from the kids’ range, in 2021 the plastic windows were removed from our gift sets, in 2022 we removed the plastic hooks for Hysteria, and in 2023, we removed all plastic hooks from all of our labels, and instead integrated a paper hook into the label. An ostensibly small amount per sock, but a lot less plastic in total!
Care for your socks properly and they'll last longer.
)
While we carry a big onus and responsibility towards our planet, don’t forget that you, too, can make a difference. Something so small as caring for your socks and making them last longer is a great step towards a more sustainable society.
Looking after your socks with care is the key to making them last longer!
More time with your Happy Socks equals less overconsumption, which in turn means more energy saved! It’s a win-win.

Taking responsibility
Although Happy Socks does not own any factories, we take responsibility to ensure the factories we work with are secure, safe and offer fair working conditions. That is why we only work with suppliers who agree to sign our Code of Conduct, a clarification of our requirements for environmental and social equity.
Since 2021, all our factories are evaluated through Amfori* BSCI for social compliance and encouraged to submit an BEPI self assessment for environmental compliance, which gives us the opportunity to monitor and evaluate the supply chain performance from both social and environmental aspects. Amfori also supports us with third-party auditing.
In 2023, we partnered up with Carbonfact that provides us with data on the footprint of all our products through Life Cycle Assessments; this goes for all of our socks, from cradle to grave.
*Amfori is an initiative aimed at improving working conditions in the global supply chain.
