New Delhi: Every two minutes a plane flies over the 13th century Qutab Minar, a fact that is giving Archaeological Survey of India (ASI) officials sleepless nights. They are worried that the vibrations from the aircraft could affect the foundation of the monument, one of the tallest in the world and which is located in a seismic zone.

Biofuels could be used to replace jet fuel in less than five years following recent tests by plane-maker Boeing, while the industry says it is putting billions of dollars into improving its environmental impact.

But ACI Europe's scheme did not set a deadline for airports to become carbon neutral -- largely by cutting emissions from ground transport, boosting renewable energy and reducing the energy consumption of buildings.

London, June 8: A new study has suggested that greenhouse gas emissions generated by trains are much more higher than those produced by an airplane.

Shipping and airlines could be tapped for money to help poor nations tackle and adapt to climate change, according to draft proposals to be presented to European finance ministers on Tuesday.

Greenhouse gas emissions from the two sectors are expected to be addressed at a United Nations meeting in Copenhagen in December to find a new global deal on fighting climate change.

SAS pilots and ground controllers in Stockholm have for years tested a new way of landing their aircraft that not only saves fuel but gives a more comfortable descent. With the "green approach," pilots take the shortest possible flight path between takeoff and landing. When they are ready to descend, they glide smoothly from cruising altitude all the way to the runway with engines idling.

Green initiatives in the air and on the ground can make a big difference in reducing an airline's environmental impact
