Environmental targets

NATS, the UK’s major provider of air traffic services and essentially a partnership between the Government and the UK airlines, has released the second quarter of performance data for its world-first environmental flight efficiency metric.
Known as 3Di, the tool is designed to deliver 600,000 tonnes of CO2 savings over the next three years – the equivalent to 10,000 flights from London to New York.  Not only will this help airlines to improve their environmental performance, it will also save them up to £120m at today’s fuel prices.
During its first six months in operation – from January to June – 3Di has achieved an indexed score of 24, as based on the scale set by the Civil Aviation Authority (CAA).  Scores run from 0, which represents zero inefficiency to over 100, with most flights typically in the range between 15 and 35.  This means NATS is on course to deliver expected fuel and emissions savings, despite a seasonal increase in air traffic.
3Di has been developed by NATS to help air traffic controllers route aircraft as close to the environmental optimum as possible by accurately measuring the efficiency of each flight in UK airspace. www.nats.co.uk
