Report on operations

In 2013, the Free Route Italy, project which is still underway, introduced new,
practically direct routings of primary interest, and used for overflight air traffic at
altitudes above FL365 (36,500 ft.), at night, on holidays, and on weekends. In January
2015 the volume of air space in question was increased by lowering the lower
limit to FL315 (31,500 ft.) thereby increasing the flight levels to which more direct
trajectories can be taken.
In addition to the Free Route Italy project, it was possible to add other new more
efficient routes, in some cases thanks to the completion of the first phase of the
JSF project which enabled the reclassification of conditional routes in the area
over the Ionian Sea and a more flexible use of military areas. Moreover, there were
improvements in route availability in terms of better flight profiles.
As a consequence of the implementation of the initiatives mentioned above, good
results were registered in 2015 following on from the good results of 2014. From an
estimate of planned savings carried out with respect to the implementation of these
initiatives and the traffic that was handled, it transpires that horizontal routing has
potentially improved by 1,404,400 nautical miles which corresponds to an estimated
reduction of overall fuel consumption of 8,189 thousand tons and consequently a
reduction in CO2 emissions of 25,795 thousand tons.
The Free Route Italy project had an assessment made of the provisions that were
completed in the first phase with respect to the traffic handled in 2015. This type of
traffic is estimated to save 120,000 nautical miles, 731 thousand tons of fuel and
reduce CO2 emissions by 2,302 thousand tons.

Green Policy in Facilities

In line with the green policies launched in recent years, ENAV is committed to reducing
energy consumption and to lowering greenhouse gas emissions by utilizing plants
for self-generation of energy from renewable sources. Moreover, in compliance with
Legislative Decree 102/2014, ENAV carried out a company-wide energy diagnosis to
gather detailed knowledge on the use and consumption of energy in the Company’s
systems and installations. This was done for the purpose of identifying and activating
a process that leads to energy saving by singling out those activities with low energy
efficiency in order to manage and/or modify them and to assess any possible saving
that can be achieved.
Overall, ENAV consumes the equivalent of approximately 11,816 tons of oil per
annum, of which 10,370 (88%) in the form of electric energy (55.5 GWh per
annum). The top 25 most energy consuming sites account for more than 80% of the
overall consumption. Equivalent CO2 emissions amount to approximately 22,900
tons of CO2 per annum, taking into account the contribution of renewable sources
in calculating the average conventional emissions factor of the national grid (Italy).
The energy diagnosis made in 2015 on a cluster of 11 representative sites, including
2 Control Centres, 7 Airport Centres, 1 RADAR site and the central premises which
account for approximately 45% of the overall Company energy consumption,
indicated that there are interesting prospects for reducing consumption through
