In 2008, Telefónica's carbon footprint was 1,818 thousand tonnes of CO2. This figure was calculated using a methodology based on the Greenhouse Gas Protocol and ISO 14064, and includes Scope 1 (direct), 2 (indirect) and 3 (other indirect) emissions.
Telefónica knows the level of its greenhouse gas (GHG) emissions, which are classified into three groups:
Since 2007 Telefónica has been using an in-house methodology based on the Greenhouse Gas Protocol and ISO 14064, which is applied throughout the Company, to calculate its GHG emissions.
Thus, Telefónica's carbon footprint for 2008 has been calculated at 1,818 thousand tonnes of CO2.

The tables below provide a detailed breakdown of Telefónica's energy consumption and the CO2 emissions associated with this energy consumption and the fuel used in employee business travel in 2008.

| 1. | This change is the result of reduced natural gas consumption in the operations of Telefónica Europe in the United Kingdom |
| 2. | The reduction in consumption in office buildings was achieved on the back of optimised consumption and shared accounting with mixed-use fixed network buildings |
| 3. | Electricity consumption in office buildings and in fixed networkd is subject to significant variations because in mixed-use fixed network buildings energy accounting is shared. The breakdown of these consumption data by country is in most cases based on estimates that are due to be fine-tuned in 2009. |
| 4. | Includes consumption of liquid fuel, gas fuel, petrol and bioethanol. Does not include natural gas. The reduction in consumption could be due to the outsourcing of operational and logistical services, or else to a lack of data. |

| 4. | The reduction in electricity consumption is due to the optimisation of electricity consumption in the network. However, emissions are higher due to the change in the emission factor for Spain from 2007 to 2008. There has been a significant decline in total electricity consumption at base stations. This may be due to the increase in own electricity generation using generators. It could also be a result of optimising electricity consumption and rolling out energy efficiency initiatives |

| 1. | This corresponds to total natural gas consumption for air conditioning and electricity generation in office buildings and networks. There has been a significant reduction in the UK |
| 2. | Fuel consumption has increased because in 2008 the figure includes consumption of fuel for heating and air conditioning in office buildings, which was not included in 2007. |
