Promoting a
low carbon strategy

In 2011 we have revised and updated our carbon strategy, the aim of which is to promote initiatives that ensure the sustainable supply of energy, energy efficiency and the development of non-fossil energies

We have exceeded our annual emissions reduction target in tons of CO2 eq, achieving over 85% of the 2005-2013 strategic objective.

Our data

In general, we report all of the environmental indicators of the companies in which Repsol has a majority participation and/or operating responsibility are included, on the basis of operational control. We also report direct greenhouse gas emissions arising from operations in which we are shareholders, wherein our reported emissions are calculated in accordance with Repsol's shareholding percentage in the relevant companies (a). We also give information on the indirect emissions associated with the purchase of electricity and steam (b), indirect emissions associated with the purchase of hydrogen (c), and on those deriving from customers' use of our products (d).

For our greenhouse gas reporting, we follow the industry guidelines drawn up by the American Petroleum Institute (API), the International Petroleum Industry Environmental Conservation Association (IPIECA) and the International Association of Oil & Gas Producers (OGP).

(35) Data on emissions from mobile sources is limited to those associated with transport.
(36) Data on fugitive and vented gas emissions is limited to that obtained from direct measurements or mass balance methods.
(37) Data from 2011 include for the first time N2O verified under the ISO 14064 standard
(38) In order to establish common bases for comparison over time, making it possible to determine the evolution of greenhouse gas emissions, the previous year's emissions have been adjusted in line with changes in the company's asset structure. The baseline change criteria are included in the oil industry guidelines for greenhouse gas reporting (API/IPIECA/OGP). In late 2010 we sold our exploration and production activities at Bermeo in Spain; therefore the inventories for 2011 and the two previous years have been adjusted to remove the emissions from the facilities sold.
(39) Data calculated based on CO2e from direct emissions (2011 data includes N2O emissions verified under the ISO 14064 international standard) and indirect CO2 emissions associated with the purchase of electricity and steam.
(40) Data on 2011 includes 1.44 million tons of natural gas consumed (1.39 million in 2010 and 1.37 million in 2009).
(41) In Spain, an additional 1710 t of HVO (Hydrogenated Vegetable Oil) were marketed.
