RTE has taken a proactive approach since 2008, carrying out a greenhouse gas balance for the fourth year in succession. The inventory was carriedout according to the carbon balance method, which is compatible with the regulatory greenhouse gas balance made compulsory in 2012 for French companies with more than500employees. In accordance with regulations, the next inventory will be conducted in 2015, on the basis of operations in 2014. 3. Explanation of the difference between 2011 and2012: a 36m 3oil leak occurred on the underground Anglo-French IFA 2000 link in 2012.84
