NATS lays out sustainable aviation strategy
The report, which is the third Corporate Responsibility report since 2008, chronicles the progress NATS has made since becoming the first air traffic management company in the world to calculate CO2 emissions in its airspace and set a target to reduce air traffic related CO2 by an average 10% per flight by 2020. To focus the company further on this goal, NATS has recently introduced another world first — 3Di, an entirely new environmental performance metric which has taken NATS three years to develop.
3Di, the 3-Dimensional inefficiency score, is a flight efficiency metric which extends the existing European horizontal flight efficiency metric to include vertical elements. 3Di seeks to account for the benefits delivered as a result of air traffic controllers delivering continuous climb departures, cruise levels as requested by airspace users and continuous descents, as well as most direct point to point routeings.
Working with airline customers and the UK regulator, NATS has integrated 3Di into its performance analytics and, as of January 1, 2012, became the first ANSP to be financially incentivised on environmental performance.
Under the incentive regime, if NATS meets its targets it could be worth up to £120 million in fuel cost savings to airlines at today’s prices, or around 600,000 tonnes of CO2 over the next three years.
Richard Deakin (above), Chief Executive Officer, NATS, said: “Fuel burn has always been a major cost to airlines. With the introduction of aviation into the European Union Emissions Trading Scheme, emissions will now be an additional cost.
“NATS has led the way by developing and committing ourselves to 3Di, a financially incentivised environmental performance metric that will support the industry in reducing costs and reducing environmental impact.”
In addition to introducing the 3Di metric, the Corporate Responsibility report highlights the steps NATS has already taken towards making aviation sustainable, including:
- NATS has made more than 100 operational and procedural changes in air traffic flows in the Swanwick, Prestwick and Oceanic regions. These have saved an estimated 115,000 tonnes of CO2 emissions – a fuel saving worth £22m.
- In 2011 alone NATS delivered over 26 changes at Swanwick and Prestwick, enabling fuel savings of over 19,000 tonnes fuel, worth almost £13m and saving 60,000 tonnes of CO2 emissions.
- The UK-Ireland FAB – the first to be established under the Single European Sky initiative – has now been operational since July 2008 and is estimated to have enabled 48,000 tonnes fuel savings, that’s 152,000 tonnes CO2.
- A new generation of advanced controller support tools became fully operational at Swanwick in November 2011. iFACTS, based on Trajectory Prediction and Medium Term Conflict Detection, provides decision-making support and helps controllers manage their routine workload, allowing the controller to check better climb profiles so an aircraft reaches cruising levels sooner and with fewer step climbs.
- In 2011, NATS established local environment action plans for the 15 airport ATC units where NATS provides the air traffic control service. During 2012 NATS will complete the work to create a baseline figure for environmental performance at each airport unit and quantify, for the first time, the contribution the airport units collectively can make to NATS’ overall 10% CO2 reduction target.
NATS remains dedicated to supporting aviation by enabling tools and technologies to improve the environmental performance of traffic in UK airspace. It is working closely with partners in the industry, making progress towards minimising the environmental impact of air traffic management to enable the sustainable growth of the industry.
