Regional Targets and Savings of CO2
To date implementation of infrastructure improvements will produce a CO2 savings of 2.12 million tonnes per year, saving USD $297 million in direct fuel costs at today’s price. 
IATA has identified 121 en-route and 40 airport improvements for implementation in 2009 based on Performance- Based Navigation (PBN) and Continuous Descent Approach (CDA).
IATA Report on Airline Requirements for Air Traffic Services
IATA's User Requirements for Air Traffic Services (pdf) offers guidance to Air Navigation Service Providers (ANSPs), states, vendors and funding organizations on airline infrastructure requirements for air traffic services between now and 2020.
This report considers technologies that are widely available or under consideration to provide Communications, Navigation and Surveillance (CNS) for Air Traffic Management (ATM).
Performance-Based Navigation (PBN)
The Global Performance-Based Navigation Task Force (GPBN/TF) was jointly formed in December 2009 by IATA and ICAO, with the purpose of supporting the global implementation of PBN. It compliments the global and regional structures in place with additional tools and enablers to expedite the global rollout of PBN. Subgroups focus on the development and promotion of additional material the education of expert teams to help states and airlines with the implementation of PBN.
The first edition of Waypoint, the official newsletter of the Global PBN TF, was released in May 2009. Airlines that wish to contribute an article on PBN should contact IATA at infrastructure@iata.org.
Continuous Descent Approach (CDA)
Continuous Descent Operations - whether it’s called continuous descent arrivals, continuous descent approaches, optimized profile descents, or tailored arrivals, is an important area for cost savings. It has taken a high profile with air navigation service providers as a short-term goal for fuel savings.
Continuous Descent Arrivals (CDA’s) save an average 150-600 kg CO2 per arrival. Eurocontrol estimates that if 20% of European airports were to implement CDAs, the annual CO2 reduction would be approximately 400,000 tonnes per year. ICAO is currently developing guidance material on CDAs, to be available later this year.
In the Flight Efficiency Plan (pdf) IATA and Eurocontrol have identified 100 airports to implement CDAs at a rate of about 20 airports per year. Including Europe, 29 airports have been identified worldwide for CDAs in 2009. A European Joint Industry CDA Action Plan was finalised March 2009, which outlines agreed actions to implement CDA’s at 100 airports in Europe by 2013 at a rate of about 20 airports a year. This will offer an early opportunity to save over 150,000 tonnes of fuel per year in European airspace.
