2 In order to know the Greenhouse Gas emissions associated with the manufacturing of supplied products, a Format for requesting data from suppliers has been prepared. We here-below provide a practical example for filling in said questionnaire. Company data: Industria Ejemplo S.A. Dedicated to cable manufacturing. Its annual production is 15,000 tons including all types of cables. It has a factory in Zaragoza. Its annual electricity consumption is approximately 1,200,000 kw/h. It utilizes 12,000 liters of gasoil/year. Let s assume that Inabensa places the following order: 3000 meter RVFV-K 1x meter H07V-K 1x 35 Industria Ejemplo S.A shall fill in 2 formularies, one for each product. H07V-K 1x35 RVFV-K 1x ,211 Industria Ejemplo S.A. Spain 400 0,546 Industria Ejemplo S.A. Spain 3000

3 In the first section of the formulary the total emissions of greenhouse gases generated in manufacturing the supplied quantity of the product the formulary refers to is requested. This information must be backed by the document that demonstrates the validity of said information. These documents are usually an analysis of the product lifecycle (APLC), product environmental statements (PES) etc. We indicate you some links where you can find information related to the calculation of GHG emissions: -Environmental products declarations: -European Platform for Life Cycle Analysis:: -Databases with emission factors for the calculation of lifecycle analysis of products

4 2.1. Product composition In this section we are going to breakdown the supplied product into its 3 or 4 main raw materials, grouping into a single raw material whenever necessary. Steel Plastic Copper - Select the raw materials that appear in the display box of the formulary. - In the event of the exact raw material not being found, indicate that which is closest and specify the same in the observations section. - In the event of the quantity of recycled material not being known, consider the lower percentage It doesnt know the quantity of recycled material

5 2.1. Emissions associated with the extraction and/or production Once the product s raw materials have been identified the emissions associated with the extraction and/or production of the same must be calculated. In the following link a list of the tools that conduct the analysis of the lifecycle of products is shown, where the emissions associated with the extraction and production of each one of the raw materials can be obtained, as can the emissions associated with product manufacturing. -Databases with emission factors for the calculation of lifecycle analysis of products 0,315 0,568 0,792

6 2.2. Fuel consumption Forklifts and other machinery are utilized to transport the raw materials and semi-elaborated product inside the factory, and these consume gasoil for this purpose. The percentage attributable to the quantity of product supplied under the order must be known. In the event of said percentage not being known, we will utilize a type ratio: There are more examples of ratios in the formulary instructions page. % = 3000 m x kg/m x 1/1000 t/kg x100;% t = Machinery Forklifts Diesel oil (l) Installation Boiler Coal others (kg) This case will also be applicable to fuel consumption in facilities such as heating, furnaces, boilers and calculation of the associated attributable percentage shall be done in like manner.

7 2.2. Emissions for combustion N CO 2 O 2 CH4 Stationary combustion CO 2 CH 4 N 2 O Mobile combustion The greenhouse gases resulting from the combustion process are Carbon Dioxide (CO 2 ), and to a lesser extent Methane (CH 4 ) and Nitrous Oxide (N 2 O). The calculation of the emissions for each gas is based on the following expression Gas i Emissions = Activity data x Emission factor gas i Fuel consumption x Net calorific value - Fuel consumption: Quantity of fuel consumed in the year referred to. - Net calorific value: This information may be obtained from the following sources which are revised annually and, therefore, the values can vary from one year to another: - IPCC Guidelines: (Volume 2, Introduction, Page 19). - Emission factors obtained from the latest national inventory presented to the secretary for the United Nations Framework Convention on Climate Change: - Net calorific value provided by the fuel supplier. In our example we will utilize the net calorific value obtained from the IPCC guidelines and the unit in which the consumption is given will have to be taken into account to obtain the activity data in TJ: AD = l x 43 TJ/Gg x 1/10 6 Gg/kg x 0.833kg/l AD = TJ

8 2.2. Emissions for combustion To fill in the emissions for combustion in section 4 of the formulary, the emissions for each gas for which we are making the calculation utilizing the following expressions must be known: - CO 2 Emission (for combustion) = DA x CO 2 Emission factor - CH 4 Emission (for combustion) = DA x CH 4 Emission factor - N 2 O Emission (forcombustion)= DA x N 2 O Emission factor Emission factors: The emission factor data may be obtained from the following sources: - Specific emission factors obtained by analytic calculation. - Values by defect obtained from bibliographical sources of reference, such as the IPCC Guidelines. Select in function of the fuel type (stationary or mobile). Select one or the other. - Emission factors obtained from the latest national inventory presented to the secretary for the United Nations Framework Convention on Climate Change. ns/items/4303.php Select the inventory of the country of origin, and find the emission factors by facility type.

9 2.2. Emissions for combustion For our example, we are going to utilize the data from the IPCC Guidelines. In this case we select mobile combustion as the combustion occurs in forklifts and we look up the CO 2, CH 4 and N 2 O emission factors for the fuel utilized diesel in this case. These Guidelines are modified annually and can therefore vary from one year to another. Emissions for combustion = AD x EF Therefore:: CO 2 Emission = TJ x kg CO 2 /TJ = kg CO 2 CH 4 Emission = TJ x 3.9 kg CH 4 /TJ = kg CH 4 N 2 O Emission = TJ x 3.9 kg N 2 O/TJ = kg N 2 O We can easily fill in section 4 of the formulary: * *

10 2.3. Electrical / heat energy consumption Industria Ejemplo S.A. consumes 1,200,000 kwh of electric energy per year. Of this quantity, it is estimated that the percentage of electricity associated with the quantity of supplied product is: % = 3000 m x kg/m x 1/1000 t/kg t x100;% = Industria Ejemplo S.A does not consume steam and, therefore, will not have emissions associated with thermal energy Electrical / heat energy consumption total emissions Calculation of the GHG emissions derived from electricity consumption or other forms of purchased energy is based on the following expression: Emission for energy consumption = Activity data x Emission factor. Activity data (AD): It is the amount of consumed electricity or energy, expressed in kw/h.

11 2.3 Electrical / heat energy consumption total emissions Emission factor (EF): It represents the unitary emissions for electricity or other forms of energy generated in kg of CO 2 equivalent/kw/h. This emission factor can be obtained from: - Utilization of emission factors obtained directly from the electricity bill. - Utilization of emission factors provided by energy regulating bodies (for example, the NEC in Spain). - Utilization of an average emission factor for country or region. These values can be obtained via: (Indirect CO2 emissions from Purchased Electricity, Heat, or Steam). This information varies annually. Electrical energy consumption emissions. In our case, we are going to utilize the average emission factor for country. We look up Spain as the factory of Industrias Ejemplo S.A. is located in Zaragoza and we then calculate the emissions as follows: : kwh x 394 g CO 2 /kwh x 1/10 3 g/kg = We can easily fill in section 4 of the formulary: kg CO

12 3. Transport of raw materials and distribution of the finished product Fill in the sections that refer to the country of origin of the raw materials that make up the product and the approximate average distance from origin to the factory. Also select the main means of transport utilized to transport said materials. Copper Steel Plastics Steel 0% recycled Italy 1099 Marítime Copper 40% recycled Germany 1510 Terrestrial - road Plastics - PVC Turkey 2572 Complete the transport of the finished product with the average distances to Inabensa 809 Terrestrial - road

13 Emissions associated with transportation of raw material and of the finished product. Calculation of the emissions relating to transportation of the product s raw materials is done by utilizing the same expression as up until now: CO 2 Emissions = Activity data x Emission factor transported merchandize (t) x Distance travelled (km) To know the emissions associated with transportation of the raw materials we would have to calculate the emissions associated with transportation of each material making up the product and add them up. In our case of the cable, it would be: Emissions associated with transportation of raw material = E transp Plastic + E transp Steel + E transp Copper. As an example, we will here-below see how to calculate the emissions associated with transportation of the Plastic material of RVFV-K 1x6 cable. Dato de actividad = (0.546 kg/m x 3000 m x 60/100x 1/1000) x (2572 km) = t km transported Plastic (t) Distance travelled (km) Plastic RVFV-K 1X6 Cable - Unitary weight of the product: kg/m - Total quantity supplied: 3000m - Percentage of Plastic in the product:: 60% - Distance travelled from Turkey: 2572 km - Mean of transport: Aerial

14 The emission factors may be obtained from the Greenhouse Gas Protocol website, where a series of tools containing Greenhouse Gas calculation sheets and step by step guidelines for utilizing the same are available. We select the sheet CO2 emissions from transport or mobile sources and look up the emission factor for air transportation in tons per kilometer, taking the fact that the trip is over 1,600 km. into account. CO 2 Emissions associated with transported plastic = t km x 0.57 kg CO 2 /t km = kg CO 2 We can easily fill in section 4 of the formulary: Steel emissions + Copper emissions

15 Emissions associated with transportation of raw material and of the finished product. We operate in like manner to calculate the transportation of the finished product from the factory to Inabensa s facilities, taking the fact that the transported merchandize is the total weight of the supplied product in tons into account. CO 2 Emissions = Activity data x Emission factor transported merchandize (t) x Distance travelled (km) Activity data = (0.546 kg/m x 3000 m x 1/1000) x (809 km) = t km Finished product (t) Distance travelled (km) We take the emission factor from the aforementioned table while taking the fact that transport is by road into account. CO 2 Emissions associated with the finished product = t km x kg CO 2 /t km = kg CO Steel emissions + Copper emissions 0.954

16 4. Other GHG direct emissions different than those resulting from combustion This section will have to be filled in when any process in the manufacturing of the supplied product is carried out, apart from combustion, in which the greenhouse gases indicated in the formulary instructions are emitted. For example, industrial aluminum degasification processes, siderurgic processes for fusion of magnesium and its alloys, and plasma processes in the electronics industry generate SF6 emissions. This section of the formulary shall be filled in by indicating the process, the emitted gas, the quantity in tons, and the percentage attributable in function of the quantity of supplied product. As an example: aluminum degasification processes
