Economic and Market-Based Measures
Economic and market-based measures are policy tools
designed to achieve environmental goals at a lower cost and
in a more flexible manner than traditional regulatory measures.
ICAO has been developing various policies, guidance material
and studies on this subject, including:
Guidance on the Use
direct terminal access and reduce congestion. These are
detailed in the following ICAO Manuals:
Airport Planning Manual
(Doc 9184);
Aerodrome Design Manual
(Doc 9157);
Airport Air
Quality Manual
(Doc 9889).
More Efficient Operations
Emissions reductions may be achieved in the short term and
with minimum investment through improved aircraft operations
and management. Improvements can be introduced to pre-flight
procedures (
centre of gravity, take-off mass, flight planning,
taxiing, APU), as well as in-flight procedures (
take-off and
climb, cruise, descent, holding and approach), and post-flight
maintenance procedures (
airframe and engine maintenance

State Action Plans To Reduce Aviation CO
More Efficient Operations, best practices in
operations – United Arab Emirates Action Plan
“In 2011, Etihad Airways, embarked on a programme to replace
3,000 containers from the original aluminium containers with
environmentally friendly lightweight versions. It is estimated that
the implementation of the new containers will cut emissions by
approximately 5,000 tons in 2012.
Emirates had replaced 40% of the heavier aluminium unit load
device (ULDs) with lightweight units, saving 23 kilograms over the
aluminiummodel. Over the 2011 to 2012 reporting year, using
the lightweight ULDs saved 4,207 tonnes of fuel and almost
19,000 tonnes of CO
emissions. When complete in 2013,
the full upgrade will save Emirates 14,475 tonnes of fuel and
45,595 tonnes of CO
emissions per year (based on 2011
to 2012 fleet size).”
More Efficient Operations Measures –
Canada Action Plan
“Reducing GHG Emissions at the Gate and on the Ground—
Airlines and airports are working together to reduce emissions
fromAPUs and ground support equipment (such as baggage
tugs and tractors). For example, in Canada, airports are
pursuing opportunities to supply their loading gates with
preconditioned air, which helps to minimize the use of APUs.
Taxi Operations: The Canadian aviation industry (airports,
airlines, and NAV CANADA) will continue to work together
to reduce GHG emissions by reducing airport aircraft ground
emissions through improved taxi and queuing procedures.
The CAC, NACC and NAV CANADA will establish an average
baseline for taxi times at the four major airports (Vancouver,
Calgary, Toronto, and Montreal).”

More Efficient Operations –
Tanzania Action Plan
• “The mitigation measure adopted by the State at current
capacity is operational. The measure involves the
implementation of several sub-measures, concurrently.
The measure which has been adopted contains the
following sub-measures: Arrivals Management, Taxiing
Management, Reduced Vertical Separation Minima,
and Departure Management.
• It has been estimated that when the total implementation
of the measure is achieved, there will be an annual
savings in fuel burn and CO
emissions of 34.4% for
total fuel burn and emissions and savings of 17.2% for
international fuel burn and emissions. It is estimated that
total benefits of the measures will be achieved by 2050.
The implementation process started in 2001, and
the realization of the benefits started to be accrued
from 2005.”
ATM and Infrastructure Use Measures –
Jamaica and Trinidad and Tobago Action Plan (for
the KINGSTON FIR and PIARCO FIR respectively)
By using the IFSET tool, Jamaica and Trinidad and Tobago’s
State Action Plans showcase the fuel efficiency within
PIARCO FIR and the Kingston FIR.
“Based on the IFSET estimations for Sangster International
Airport, and by Jamaica using the CDO, the fuel savings are
estimated to be 21.5% and 44,415 kg of CO
each month.
RNAV routes used in the PIARCO FIR reduced mileage and
reduced fuel emissionsexample: 2% and 5% fuel savings
(based on the selected for RNAV route) and a reduction of
of 334 and 550 kg (based on the selected RNAV route).”
