The planet
Lower fuel consumption. Less emissions.

The less fuel burned the cleaner the atmosphere. Imagine saving up to 65 tons of CO2 - per aircraft per year! - as is the case with a narrow-body aircraft. Or up to 160 tons with a wide-body aircraft in regular service.

The calculations further back also show significant reductions of nitrogen oxides, hydrocarbons and carbon oxide.


Let's calculate!

Example Boeing 737NG
Can save:
65 tons CO2*
21 tons less fuel consumption*

Reduced emissions - per aircraft and year:
CO2                      65            ton
NOX              190            kg
HC                  35            kg
CO                460            kg

*Based on 3,000 flight hours per year. 200 kg less weight gives a fuel saving of 7 kg per flight hour with a 90% load factor, fuel efficiency factor of 3.5%. Source: www.luftfartsverket.se (Figures are approximate)


Example Airbus A330-200
Can save:
165 ton CO2*
52.5 tons less fuel consumption*

Reduced emissions - per aircraft and year:
CO2              165            ton
NOX             630             kg
HC                   1             kg
CO                 85             kg

*Based on 5,000 flight hours per year. 300 kg less weight gives a fuel saving of 10.5 kg per flight hour with a 90% load factor, fuel efficiency factor of 3.5%. Source: www.luftfartsverket.se (Figures are approximate)
  • Carbon dioxides (CO2). Contributes to the greenhouse effect that results in an increase of the earth's average surface temperature.
  • Nitrogen oxides (NOx). Contributes to acidification and over fertilization of land and water.
  • Hydrocarbons (HC). Ground-level ozone that is created by reaction with sunlight can harm vegetation and affect human health.
  • Carbon oxide (CO). Detrimental to human health.
