[A] Greenhouse gas emissions comprise carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride. The data are calculated using locally regulated methods where they exist. Where there is no locally regulated method, the data are calculated using the 2009 API Compendium, which is the recognised industry standard under the GHG Protocol Corporate Accounting and Reporting Standard. There are inherent limitations to the accuracy of such data. Oil and gas industry guidelines (IPIECA/API/IOGP) indicate that a number of sources of uncertainty can contribute to the overall uncertainty of a corporate emissions inventory.

[B] Nigeria includes SPDC onshore operations (1.2 million tonnes flared in 2014) and SNEPCo offshore operations (0.01 million tonnes flared in 2014).

[C] Flaring from the Majnoon field in Iraq and from Malaysia amounted to 1.4 and 0.4 million tonnes of hydrocarbons respectively in 2014.  

[D] Since 2012 data is prepared in accordance with IPIECA/API/IOGP guidance 2010. Data for prior years is not directly comparable.

[E] The data includes mining and upgrading operations. It does not include in-situ production.

[F] Data is indexed to 2002, based on Solomon Associates Energy Intensity Index 2006 methodology.

[G] All spill volumes and numbers are for spills over 100 kilograms. 

[H]As of the end of March 2015, there was one spill under investigation in Nigeria that may result in adjustments, which took place prior to 2014.

[I] All sabotage- and theft-related spills have occurred in Nigeria except in 2007 (0.7 thousand tonnes outside Nigeria) and 2006 (0.6 thousand tonnes outside Nigeria).

[J] Nigeria includes SPDC onshore operations and SNEPCo offshore operations. A single spill at the Bonga field offshore Nigeria amounted to 4.8 thousand tonnes in 2011.

[K] The numbers of operational spills reported for 2005 contain a small number of hurricane spills.

[L] Nigeria includes SPDC onshore operations (37 operational spills in 2014) and SNEPCo offshore operations (1 operational spill in 2014). 

[M] In 2014, we sent waste offsite for recycling or reuse, or sold over 500 thousand tonnes of material that would otherwise have been disposed of as waste.
