Notes:
1) (A)= advance data. 
 2) The HFC category includes HFC-PFC mixtures. 
 3) For the aggregation of gases by environmental problem, the mass of the corresponding gas is multiplied by an established calculation factor: for GHGs by Working Group 1 to the Fifth Assessment Report of the IPCC (AR5) and for GAC and PRO3 by the Agency European Environment Agency (EEA) and Eurostat.
