1 STUDY CASE OF CARBON FOOTPRINT CALCULATION IN THE FOREST SECTOR Maderas Siero S.A. Susana Martínez

2 Index -SIERO GROUP -History and actuality -Activity -Company Philosophy -Our motivation to calculate the Carbon footprint -Our carbon footprint calculation -Our products -Project stages -Definition of process map -Scope establishment -Data compilation -Calculation process -Reduction plan -Following steps -Wood as material -Conclusions

3 SIERO GROUP Family company established on 1985 and located in Asturias (North Spain) Biggest group specialist in Sweet chestnut wood in Europe Company oriented to innovation and continuos improvement Social y enviromental responsible: FSC and PEFC forest certification for own forest FSC and PEFC Chain of Custody Certification

4 SIERO GROUP : Activity MADERAS SIERO (1st transformation) Forest management and exploitation Sweet Chestnut sawmill (lumber and massif beams) Hardwoods trading Poles and fencing Firewood and chips (biomass) SIERO LAM (2nd transformation) Manufacturing and distribution of: Laminated products (panels, scantling and glulam beams) Solid flooring, cladding and decking Other complements: frieze, sandwich panel

5 Integral control of the process from the forest to the final products our sostenibility as a company depends on the environment conservation, frame work of our activity Forest Certification fsc Chain of Custody CdC fsc

6 Our motivation to calculate the carbon footprint Internal Strategy Analysis situation Indicators for decision making Sustainable development model Resource optimization External Strategy Reinforce our brand image Communicate Satisfy clients needs Introduction to voluntary markets with emission requirements Access to the public green procurement

7 Calculation of our footprint Methodology: PAS2050 (BSI), the most complete and operational Choice of the product: Chestnut planks (the more complex product in the sawmill) Period of study (baseline): 2011

8 Chestnut Sawmill Which are our products? Massif beams and ceiling joist (custom) Planks and boards: 27, 30, 40, 50 y 75mm Hardwoods Importer and trader Fencing : poles, post and stakes Firewood: in oak, beech and chestnut

9 Phases of the project Definition of the Process Map Define the Scope Identify the stages of the process related to production, raw material and define the functional unit Once defined the functional unit we should delimit the scope of the project Data Collection Data related to the activity (primary or secondary) Calculation Process Sum of materials, energy and waste along the life of all the activities in the cycle life of the product, multiply buy its emission factor

10 Process template of a chestnut plank FOREST MANAGEMENT LOGS TRANSPORT TO THE SAWMILL FOREST EXPLOITATION SAWING LUMBER AUTHOMATIC STACKING AIR DRY KILN DRY Functional unit: 1 m 3 planks (commercial unit more use in this kind of product) WOOD EDGING (MULTIPLE RIP SAW) WOOD SURFACING WOOD OPTIMIZATION WOOD CLASIFICATION

11 Definition of the Process Map Raw materials Manufacturing Distribution Fuels consumption Chestnut wood Pine wood Packaging Natural gas Fuels consumption Transport Forestry Process: - Sawing - Air drying - Wood drier - Edging, planing, optimized and classified --Storage Fuels consumption Electricity consumption Transport Fuels consumption Transport Cogeneration Raw materials production Transport Stages Emissions sources Waste treatment Biomass boiler Heat production Natural gas consumption Electricity production Sale

12 Definition of the Scope We have considered the emissions originated by direct sources, the indirect sources from energy, and a part of emissions derived of the supply chain. That is, from the logs extraction in the forest to the selling of the planks, without considering its final use ( cradle to gate ). The impact of the emissions derived from the life cycle of the selected product was considered as a period of 100 years since the manufacturing of the product.

13 Data collection Todos los datos empleados han sido primarios Input and Output of raw material Quantity and composition of inputs and outputs in each stage of the project: Input raw materials Output products Sub-products Waste Used energy GEI emissions Distribution &Transport Type, resources and quantity of the energy consumption: electricity, fossil fuels, Type and quantity of direct emissions GEI Type of vehicles, average driving distance, staffing percentage of the vechicles,.

14 Calculation process: assiment of loads

15 Calculation process: Numbers Forest Explotaition: CO 2 e Emissions = Fuel consumption (litres) x emission factor (CO 2, CH 4 y N 2 O) = 31,2 kgco 2 e Transport: CO 2 e Emissions = Distance x Fuel consumption (litres) x emission factor (CO 2, CH 4 y N 2 O) = 59,7 kgco 2 e Aserradero Electricity consumption for functional unit (1m 3 planks) = 292,86 kgco 2 e 300,0 KgCO 2e 250,0 2,0 1,5 1,0 0,5 0,0 Pala cargadora Sierra Robot apilador Secadero Canteadora Cepilladora Optimizadora Almacenaje

16 Calculation process: Results Local lumber: 387,76 CO 2 e Lumber imported from France: 640 kg CO 2 e Lumber imported from Finland: kg CO 2 e

17 Reduction planning Reducing emission derived from fuels Reducing the kiln dry time Renewable energies Compensatio n: forest certified fsc

18 Following steps Calcultation of Corporative Carbon footprint Carbon footprint Certification Findings Publication and y communication to clients

19 CONCLUSIONS Improves your company image and the Corporate social responsibility. Increasing of the competitiveness, as it shows distinction comparing with other companies. Allow us to introduce to new markets where they are already demanding this kind of information, as France and the UK. Advantages as government supplier in the more and more promote GREEN PUBLIC PROCUREMENT It prepare us for possible mandatory legal requirements in the future The carbon footprint (HC) quantifies the amount and the origin of the Greenhouse Gas emission Allowances (GEIs), that allow us to analyse the main activities causing such gases.
