Таблица:
Energy consumption: 5.22 billion ton EOC

Вообще опыт подсказывает мне, что речь идет об эквиваленте энергопотребления в виде нефти, угля и т.п. и О означает oil, что-то типа E Oil Consumption ...

For materials, processes and products the environmental notes are intended to supply the reader with the very basic environmental information in relation to toxicity and occupational health hazards. To support a very simple LCA (life cycle assessment) the energy consumption is indicated as the equivalent oil consumption (1 kg of oil equals 45 MJ of energy). NOTE: Energy figures should not be compared between materials, but used for estimating total energy consumption for a product from cradle to grave!
