The sectors are labelled as follows:
energyprod - SNAP 01 (Combustion in Energy Production and Transformation)
domcom - SNAP 02 (Combustion in Commercial, Institutional, Residential and Agriculture)
indcom - SNAP 03 (Combustion in Industry)
indproc - SNAP 04 (Production Processes)
offshore - SNAP 05 (Extraction and Distribution of Fossil Fuels)
