5 4. OPERATIONS LIMITS AND EXCLUSIONS The GHG considered in this report are: CO 2 SF 6 (Fugitive emissions expressed in CO 2 eq) CH 4 (Fugitive emissions expressed in CO 2 eq) IBERDROLA defines the scope of their direct and indirect emissions for operations within the limits of the organization. According to the UNE-EN-ISO 14064: 2012, the classification of GHG emissions is: Scope 1 - Direct GHG emissions Direct GHG emissions from sources owned or controlled by the Company. The following are included: Emissions from energy generation facilities (fuels consumption) Emissions from energy generation facilities burning biomass Emissions from no energy generation facilities (natural gas storages and sludge process) Emissions from methane (CH 4 ) leaks (natural gas storages and transport) Emissions from sulphur hexafluoride (SF 6 ) leaks in distribution networks Emissions from services equipment in buildings (fuels consumptions) Emissions from mobile sources related to business trips in company cars (reported Scope 2 - Indirect GHG emissions Indirect emissions are those deriving from the Company's activity, but generated by other organisations, and include the emissions from the generation of electricity acquired and consumed by the Company. These emissions are: Emissions associated with the consumption of auxiliary energy during stop in thermal, renewable and nuclear plants and pumping operations in hydro plants Emissions associated with the consumption of electricity in buildings Scope 3 - Other indirect emissions All other indirect emissions which are a result of the Company's activities but occur in sources that are not owned or controlled by the Company. These other emissions are: Exclusions: Emissions from mobile sources related to business trips in rental cars, owned cars, plane, train and boats Emissions associated with fuel transport Emissions associated with the distribution of energy from other generators Emissions associated with suppliers who receive and respond to GHG questionnaires Emissions associated with employee commuting This section contains the exclusions made by IBERDROLA in the GHG inventory. Emissions from mobile sources in generation plant (low representativeness < 5% in relation to the facility's total emissions) Emissions that represent difficulty to incorporate into corporate systems. Included in this groups are: o Emissions associated with employee transport in the Mexico Region o Emissions associated with fuel transport in Mexico, Brazil and US Regions

8 7. UNCERTAINTY AND MAXIMUM RELATIVE SIGNIFICANCE The estimated uncertainty of the emissions is a combination of the uncertainties in the emission factors and those of the corresponding activity data. The emission factors used to create the IBERDROLA GHG Inventory are extracted from official sources and are specific to each source category. The selection of these emission factors is aimed at minimizing uncertainty as far as possible. Unless clear evidence to the contrary is available, it is assumed that the probability density functions are normal. The uncertainty of the activity data used to create the IBERDROLA GHG Inventory is secured on the one hand, through self-regulation in the country who participates in the EU ETS (Emission Trading System), and for those who don t through the calibration of measuring equipment according to technical specifications or procedures for each facility. A maximum relative significance level has been established at 5% in relation to total emissions, except for those facilities which are subject to regulatory verification, in which case it will be 2 or 5% according to the requirements set forth in Decision 2007/589/CE. 8. BASE YEAR SELECITON IBERDROLA considers 2012 to be the historical GHG Inventory base year according to ISO :2006 Standard Greenhouse gases. Part 1: Specification with guidance at the organization level for quantification and reporting of greenhouse gas emissions and removals. The base year will be updated when any of the following aspects takes place: Changes in the operating limits. Major structural changes. Structural changes entail the transfer of ownership or control of operations of the GHG sources. Changes to the GHG quantification methodologies and/or improved accuracy of the emission factors that result in significant changes in the quantified emissions.

9 9. QUANTIFICATION METHODOLOGIES 9.1 Direct Emissions Direct emissions from power generation facilities (fuel consumption) The direct emissions associated with power generation are the CO 2 emissions produced from fossil combustion processes in power generation facilities: Thermal power generation (fuel-oil, carbon), Combined Heat and Power (CHP), Co-generation, thermosolar facilities, oil and nuclear power plants. Quantification methodology is based on activity data (based on fuel consumption) and on the emission factors (whether they are calculated or obtained from official sources) Emissions from biomass facilities These CO 2 emissions are produced by combustion of biomass. The calculation of emissions associated with biomass plants are based on activity data (fuel consumption) and emission factors from official sources. In 2014 there were no emissions in this category Emissions from no energy generation facilities (gas storage and drying of sludge) These CO 2 emissions are produced by thermal drying process in Daldowie plant in Scotland, UK, and in the gas plants at Hatfield, UK, and Enstor, USA Emissions from methane (CH 4 ) leaks in natural gas transport To calculate the leakages of CH 4 emissions produced in the transport of natural gas, it is used the Factor of Global Warming Potential published by the Intergovernmental Panel on Climate Change (IPCC) for a horizon of 100 years Emissions from sulphur hexafluoride (SF 6 ) leaks in distribution networks To calculate the leaks of SF 6 in distribution networks it is used the Factor of Global Warming Potential published by the Intergovernmental Panel on Climate Change (IPCC) for a horizon of Emissions from facilities that provide services to buildings (fuel consumption, Diesel, Natural Gas and LPG) The quantification methodology is based on activity data (different fuel consumption) and emission factors obtained from official sources for such fuels (diesel oil and natural gas) Emissions from combustion associated with employees' road translation with fleet vehicles The quantification methodology used for the calculation of direct emissions is based on activity data (fuel consumption or kilometers traveled) by the emission factor obtained from specific official sources. 9.2 Indirect GHG emissions The indirect emissions are: Emissions associated with the consumption of auxiliary energy during stop in thermal, renewable and nuclear plants and pumping operations in hydro plants Emissions associated with the consumption of energy in buildings To calculate indirect emissions the generation mix emission factor of each country is used. Data sources: CO2 Emissions per kwh from Electricity and Heat Generation from the report CO 2 EMISSIONS FROM FUEL COMBUSTION 2015 Edition from the International Energy Agency. Emission Factors For Spain, emission factor is taken from the document "Observatory of electricity. Year 2015.

10 9.3 Other indirect emissions To calculate the CO 2 eq emissions the generation mix emission factor of each country is used Emissions associated with employee transport for business (rental and private cars, airplane, rail and ferry) In order to calculate emissions associated with employee transport by different means of transport (car, air travel and rail), we apply the most specific emission factors from DEFRA Greenhouse Gas Conversion Factor Repository, data for Emissions associated with fuel transport In order to calculate emissions associated with fuel transport (coal and uranium) to generating plants by different means of transport (car, air travel and rail) emission factors from DEFRA Greenhouse Gas Conversion Factor Repository, data for Emissions associated with the distribution of energy from other generators To calculate the emissions, the generation mix emission factor of each country is used. Data sources: CO2 Emissions per kwh from Electricity and Heat Generation of the inform CO2 EMISSIONS FROM FUEL COMBUSTION 2015 Edition International Energy Agency. Emission Factors For Spain, emission factor is taken from the document "Observatory of electricity. Year Emissions associated with suppliers who receive and responded to GHG questionnaires During the year 2015, the VI Campaign to raise awareness and measurement of greenhouse gases suppliers was developed, and questionnaires were sent to the Group's suppliers in Spain, UK USA and Mexico. An specific questionnaire and helpful information and support on the issue were sent to more than 1000 suppliers worldwide. From the responses obtained from the questionnaires, IBERDROLA considers as own those emissions proportional to turnover of the supplier to IBERDROLA compared with the total turnover of the supplier Emissions associated with employee commuting During 2015, the VCampaign to raise awareness and measurement of greenhouse gases emissions in employee commuting has been developed. For this purpose, a questionnaire was sent to all employees from IBERDROLA s Group, so that they could calculate their emissions using an emissions calculator tool. Approximately 5% of the employees have answered the questionnaire and this data have been incorporated into IBERDROLA s GHG emissions inventory. Date of completion of the Report 13/04/2016
