Steel manufacturers ArcelorMittal and Tata Steel and cement maker LaFarge were the three companies with the most freely allocated surplus EU carbon allowance for 2012.
RWE emitted 157 metric tons of CO2, followed by Vattenfall with 92 MtCO2 and E.On with 90 MtCO2. The three companies also had the largest shortfall of surplus carbon allowance.
Carbon Data, a market research firm, takes into account all the companies in which the groups have stakes and its rankings report came after announcements of verified emissions reports for 2012.
ArcelorMittal, the world’s biggest steel maker, continues to dominate the surplus allowance ranking with a surplus of 37 million EU allowances in 2012. At the current EU allowance price of €3.9 ($5.17), this surplus represents a selling value of €145 million ($192.05 million).
Tata Steel, which owns Corus, had a surplus of 19 million EU allowances, and LaFarge had a 12 million EU allowance surplus.
E.On surrendered the largest amount of certified emissions reductions, at 27 million, to the EU member states, followed by Enel at 16.5 million and GDF-Suze at 8.5 million.
The companies that topped the list of those that surrendered the most emission reduction units for 2012 compliance include RWE (15 million), CEZ (12.5 million) and E.On (11 million).
Among airlines operating in the EU, Ryan Air topped the list of carbon emitters, followed by Lufthansa and EasyJet. A total of 775 airlines are included in the emissions trading scheme.
Earlier this week, the International Air Transport Association, which represents 85 percent of the world’s airline traffic, adopted a resolution calling for a single, industry-wide market-based measure to manage and offset emissions.
