The heavier an aircraft, the more fuel it consumes. Cargo and baggage constitute a large portion of an aircraft’s weight. For each reduction of 1 kg (2.2 lbs) per passenger, an aircraft can save 9,000 gallons of fuel annually. Each individual traveler can make a big difference in fuel consumption by packing lightly. The cumulative weight reduction will reduce the total loaded weight of the aircraft and enhance fuel economy, which in turn means fewer CO2 emissions. Packing tips can be found in many sites online. For example, see the packing tips from the American Society of Travel Agents.
