The aviation industry accounts for nearly five percent of global carbon emissions.
NATS, the main air navigation service provider in the United Kingdom, is seeking to reduce the carbon footprint of air travel by developing better navigation tools. Its award winning 3Di tool compares the trajectory and route of an aircraft, obtained from radar data, with an optimal profile that would minimize fuel burn and CO2. This enables an exact measurement of the effect of air traffic control instructions, requested cruise levels and direct point-to-point routes on fuel burn and carbon emissions.
By 2015, the 3Di tool is expected to reduce carbon emissions by 600,000 tons and deliver fuel savings of nearly $190 million.
