Use advice for data set	Product Stage / A1 Raw materials: Martela has long partnerships with its suppliers and subcontractors, who buy raw materials to their products and components from their suppliers, respectively. Main suppliers are locating in Europe. Wood material is coming from sustainably cultivated forest (FSC, PEFC, etc) and fabrics can be chosen from our standard collection with Öko tex or EU ecolabel certificates. Recycled materials are taken to use based on availability and when they fulfill the technical requirements set for the end products. Materials are including the product package to our customers. Packages that are coming from suppliers are re-used in customer delivery phase (like pallets) or handled as waste in Manufacturing phase A3. Customer delivery package is disposed in Installation phase A5. Product Stage / A2 Transport: Transportation is calculated from suppliers location to our own factories in Nummela and Poland and between our factories when delivering components to final assembly phase in our logistics center in Nummela. Product Stage / A3 Manufacturing: Martela has two own factories for manufacturing these products. Poland factory is producing sewing and upholstery parts to chairs and screens. Production unit in Nummela make final assembly of the products based on customer orders. Nummela factory is using renewable electricity and heating energy. From factory waste 98% is recovered. Poland factory is in rental premises and cannot choose its used energy, so in calculation we are using Poland average factors.
Technical purpose of product or process	The Grip NxT stool is available with two height options and with or without upholstery. Without upholstery it can be hung on a tabletop without a separate hanger. Grip Nxt stool height 45 cm Base: painted grey, white, black or Inspiring Colours Felt glides Form-pressed seat in laminate

General comment on data set	Data quality: Specific data for the product composition are provided by the manufacturer. They represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on registered EPDs according to EN 15804, Ostfold Research databases, ecoinvent and other LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances.

¹This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
²The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
