New LaGuardia to reduce emissions from taxiing

New York's redeveloped LaGuardia airport is to cut emissions by reducing aircraft taxiing times.

The current airport is being demolished and rebuilt, with one linked building replacing its disconnected terminals.

Three winning designs submitted in a worldwide competition are being combined for the project, with work due to start next year and complete in 2020 under the auspices of lead architect HOK.

A key feature of the remodelled hub will be raised pedestrian bridges, linking gates to the terminal, that are high enough for aircraft to pass under.

The innovation will help create around 3.2 kilometres of new taxiway space at the airport, leading to reduced fuel wastage.

"This allows for a more efficient circulation of aircraft and reduced taxi-in and taxi-out times, which will yield shorter and fewer gate delays a dramatic difference from today's LaGuardia," said a spokesperson for the office of New York Governor Andrew Cuomo.

"In addition, this change will produce overall reduction in carbon emissions from idling aircraft."
