working with colleagues across the Agency
to ensure that environmental issues are taken into
account.
The Performance Review Report for 2006 (PRR
2006) highlighted the negative environmental impact
of non-optimum routes, and estimated that as many
as 4.7 million tonnes of CO2 are released unnecessarily
into the atmosphere each year by aircraft
which might have been able to fly more efficient
routes had they been made available. The adoption
of a flight-efficiency target was therefore advocated
by the Performance Review Commission (PRC),
specifically to promote more direct routes and prevent
needless CO2 emissions.
EUROCONTROL has launched a number of programmes
and developed a number of toolsets over
the years, which although focusing on the safe ex-

pansion of capacity are also designed to reduce the
environmental impact per flight. Specifically, these
are the DMEAN and Airport Operations Programmes.
Reducing taxi times at airports has the
potential to save many thousands of tonnes of fuel
and CO2 a year, as EUROCONTROL operational trials
have demonstrated. These build on the introduction,
in January 2002, of six additional flight
levels over continental Europe under the RVSM Programme,
which reduces CO2 emissions by almost 1
million tonnes every year. The Agency also plays a
key role in ensuring that environmental issues are
given high priority within the most important current
European ATM initiative, the Single European Sky
ATM Research (SESAR) Programme.
Dynamic Management of the
European Airspace Network
(DMEAN)
The DMEAN Framework Programme is a significant
step towards the Single European Sky, insofar as it
seeks to optimise the results of today’s technology
and procedures to absorb projected traffic between
now and 2010. Its set of short-term outcomes or
“quick wins” will ensure that improvements in efficiency,
and therefore environmental sustainability,
are achieved in the years leading up to the start of
SESAR deployment. The improvements in flight efficiency
brought about by DMEAN could save up to
120,000 tonnes of CO2 annually.
Continuous-descent
approaches
Work on Continuous-Descent Approach (CDA)
techniques continued throughout 2006. Flight trials
conducted by EUROCONTROL in collaboration with
airlines, air navigation service providers and airport
operators have proved that this concept greatly
reduces aircraft emissions, fuel consumption and
noise. Harmonised guidance material on CDAs
should be issued in mid-2007.
In the coming years, CDAs will be increasingly used
at times of heavy traffic load, thanks to more accurate
navigation (P-RNAV) and advanced controller
productivity tools (as combined in the TMA 2010+
initiative). In the medium term, it is possible that a
significant proportion of all flights landing in the
ECAC region will use CDA techniques. Fuel savings
of up to 825,000 tonnes and a reduction in emissions
by as much as 2.6 million tonnes annually, are
targets well worth aiming for.
PAGODA
EUROCONTROL’s own tool for providing environmental
performance indicators was launched for
beta-testing in December 2005. Originally designed
to estimate fuel burn and greenhouse gas emissions
in the pan-European ATM network, its capabilities
were extended to increase the scope of the performance
indicators it can calculate. Work was
therefore carried out to develop indicators for network
(flight) environmental efficiency which have underpinned
the Performance Review Commission’s
work in this area.
PAGODA’s fuel-burn and emissions estimates have
also provided stakeholders with a common set of
reference data on which to assess the European
Commission’s policy proposal to include aviation
emissions in the EU’s Emissions Trading Scheme.
The Agency continues to receive requests for data
support as progress is made towards the adoption
by the Council and Parliament of a commonly
agreed legislative proposal.

cooperation
The implementation of the Flexible Use of Airspace
(FUA) concept in Europe over a ten-year period will
reduce CO2 emissions by more than 300,000 tonnes
a year. The Organisation’s Environmental Policy and
Strategy is shared with military users through the Directorate
of Civil-Military ATM Coordination, which
raises awareness among military stakeholders of ongoing
