Our results

Greenhouse gas emissions (44)

Our direct emissions of CO2e fell by 1% compared to 2010, due mainly to reduced activity in exploration and production operations in Argentina, caused by union conflicts in Santa Cruz (Argentina) and by replacing liquid fuels with gas fuels at the A Corua refinery.

This reduction in CO2e essentially reflects a reduction in CO2 of 2%, while methane has remained virtually unchanged. Additionally, N2O emissions verified under ISO 14064 standard criteria have been included for the first time in our measurement of direct emissions of CO2e, resulting in a lower reduction percentage than in previous years.

During 2011, Repsol extended the scope of its CO2 inventory verification under the ISO 14064 international standard, achieving the first certifications in Latin America in the Upstream business. These operations were in Margarita in Bolivia, the Block 16 operation in Ecuador and Barrancas in Argentina. The addition of these operations means that 75% of the inventory of direct CO2 emissions is currently certified under this standard.

Flared gas increased 16% due mainly to the implementation of the C-10 project at the Cartagena refinery and to stoppages in several compressors in exploration and production in Trinidad and Tobago.

Furthermore, thanks to the reduction actions implemented in the La Plata and Lujn de Cuyo Refineries in Argentina and in Block 16 in Ecuador, CO2 emissions associated with flared gas fell by 244.367 tCO2.

In addition to our direct emissions, we also annually report our indirect emissions of greenhouse gas, the following result from our activity but come from sources owned or controlled by third parties. In 2011:

  • Emissions from purchased electricity or steam amounted to 1.56 million metric tons of CO2 equivalent
  • Emissions associated with manufacturing and transporting hydrogen stood at 0.94 million metric tons of CO2 equivalent

Emissions from the fuels we market

Emissions from our customers' use of the fuels we market stood at 145.77 millions of metric tons of de CO2 (48) in 2011.

Energy consumption

In 2011, our total energy consumption fell by 2% due to the implementation of the C-10 project in the Cartagena Refinery during the 4th quarter.

Of the company's total energy consumption, 92.9% is direct and 7.1% indirect (resulting from purchased electricity or steam from third parties).

Distribution of biofuels

Repsol relies on a balanced market for obtaining and processing raw materials for biofuel production and takes the measures necessary to mitigate risks in our supply chain. The European Directive on promoting the use of energy from renewable sources defines sustainability criteria for biofuels. Its purpose, among others, is to protect land high in biodiversity value or with large carbon sinks. In Spain, Royal Decree 1597/2011 of November 4, regulates sustainability criteria and the national sustainability verification system, applicable as of January 1, 2013. The National Energy Commission (CNE) leads the specification of the operational aspects needed to ensure compliance with the Royal Decree; Repsol is an active participant in the working group set up for this purpose.

This European Directive delegates to the Commission the study and development of proposals and methodologies to measure emissions from carbon stock changes caused by indirect changes in land use. The European Parliament and Council must approve the measures to be adopted before December 31, 2012.

In undertaking its biofuel development and production projects, Repsol ensures full compliance with specified sustainability criteria.

In 2011, Repsol met its mandatory minimum annual targets for biofuels sales and/or consumption for transport in all the counties in which we operate. In 2011 in Spain, we distributed 843,000 tons of biodiesel, 242,000 tons of bioethanol and approximately 1,710 tons of hydrobiodiesel.

(46) 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, using criteria 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 exclude the emissions from those facilities.
