TRACE YOUR PRODUCTS
K Group is constantly striving to improve the transparency of its purchasing chains. On this website, our customers can find out more about where the products they purchase from K Group stores come from.
Where do mywear t-shirts, Pirkka and K-Menu tuna products, Pirkka Fairtrade roses, and PROF Timber sold in our stores come from? We want to increase the transparency of our purchasing chains by providing information on the origin of our products and their journey to our stores. Choose a product to find out more.
Sourcing is guided by Kesko’s timber and paper policy. Kesko’s target is that by the end of 2028, 100% of Kesko’s own brand timber and paper products will be certified or made from recycled materials and/or materials of verified origin.

The certification includes requirements aimed at supporting forest biodiversity, regeneration capacity and vitality, while taking into account the ecological, economic and social impacts of forests.

Read moreThe origin of K-Rauta’s PROF Timber products is always traceable. The K-Rauta stores purchase a great deal of wood that has been felled and processed in their local areas, meaning that the costs and the carbon dioxide and particle emissions arising from transport are moderate.
Reducing waste is an integral part of the PROF Timber concept in the purchasing chain from the forest to the end customer. In 2025, we proceeded towards the goal and reduced waste by some 134,000 logs. If put in a line, these logs would stretch some 717 kilometres. Waste is reduced through packaging development and by selling products at fixed lengths, enabling the customer to buy timber at a length that best suits them.


Growing trees store carbon from the atmosphere. When a tree is felled and used as a building material, its life continues as carbon storage. The carbon stored in wood will not be released until the wood is burned. Even then, no more carbon dioxide will be released into the atmosphere than was stored in the tree during its growth.
PROF Timber comes from certified Finnish forests. From the forest, the wood is transported to be processed at sawmills, where it is sawn, dried and sorted. From the sawmills, the timber is transported either to be further processed or to be sold at K-Rauta stores. The by-products of sawing are reused.
PEFC is an international forest certification system whose aim is to promote sustainable forestry worldwide. PEFC certification for the origin of wood includes requirements for forest management and use and the monitoring of wood raw material and timber in the supply chain. More than 50% of certified forests globally have been certified in line with the PEFC system. Around 90% of Finnish commercial forests have a PEFC certification.

PEFC certification sets criteria for forest management, covering themes such as:
- Ensuring the quality of forest management work
- Ensuring the health of trees
- Harvesting fuelwood
- Taking good care of seedling stands
- Protecting ecologically important forest areas
- Maintaining biodiversity and leaving retention trees and decaying wood in felling areas
- Ensuring the high quality of groundwater, natural waterways and small bodies of water
- Maintaining the carbon sink created by the trees in forests
- Ensuring employees’ competence, well-being at work and safety
- Promoting children and young people’s forest knowledge and relationship with nature
- Ensuring the recreational use of forests
- Respecting the rights and livelihoods of indigenous peoples
A PEFC label on product packaging means that each company that has processed the timber has a PEFC monitoring system for the origin of wood. It enables the company manufacturing or using wood products to reliably ensure that the product contains wood sourced from certified forests. Independent auditors regularly monitor to ensure that the origin of the wood raw material is traceable.
