by the Argentine government to nationalize its oil and gas production. Results however show that the move to nationalize actually hurt oil production in Argentina. Compared to the oil production in 2011, YPF's oil production in 2012 fell by 8%, according to data from Argentina's Department of Energy. Repsol had the backing of the EU and the US, and both powers condemned Argentina's move as expropriation. President Fernández claimed that the state would seize 51% of YPF. In June 2013, Repsol rejected a $5 billion proposal from Argentina to compensate for the 2012 expropriation. The proposal also would have given Repsol drilling rights to 6.4% of the massive Vaca Muerta shale-gas field. The board of Repsol unanimously rejected this offer, as it would have caused them to drop a $10.5 billion lawsuit that was in progress against the Argentine government. Repsol at the time owned 6.4% of YPF. On 25 February 2014, the Repsol board announced it had accepted a settlement offer from the Argentine government of an issue of Argentine bonds valued at $5 billion. The deal concluded after three months of negotiations in Buenos Aires was subject to shareholder approval. The agreement ended two years of legal wrangling and the potential for a long drawn-out legal battle. Repsol Chairman Antonio Brufau described the "friendly" settlement as "extremely positive." Environmental record In 2011 Repsol built the world's first service station certified by BREEAM, "the leading international method for evaluating and certifying building sustainability". The construction of the station was completed under green architecture parameters, utilizing multiple recycled materials. The publication Newsweek selected Repsol as the most environmentally respectful energy company of 2012. However, recent reports of Repsol drilling in the indigenous lands of the Peruvian Amazon display a disregard for the environment. According to an Environmental Impact Assessment, Repsol's exploration of the rainforest will involve drilling at least 21 wells. Although Repsol denies it, 20 of the 21 wells fall within the land of indigenous people, who are very vulnerable to any sort of contact with foreigners. In 2016, Repsol ranked as being among the 12th best of 92 oil, gas, and mining companies on indigenous rights in the Arctic. In 2021, Repsol was ranked no. 9 in the Arctic Environmental Responsibility Index (AERI) that covers 120 oil, gas, and mining companies involved in resource extraction north of the Arctic Circle.
