American EPA methods for calculating aircraft emissions. See Chapter 5 particularly.

Danish government report on emissions.

LTO

• Figures for LTO ( Landing Take-Off Cycle) emissions
• More LTO emissions data

Existing calculators

• Those Swedes are at it again SAS allow passengers to calculate their emissions.
• A site full of flight induced emissions data including a calculator ( limited to B747 ).
• Carbon Neutral from Australia, with figures showing the amount of trees to be planted to offset air travel.
• just what I hope to do.
• C02 Equivalents from IETA
• Edinburgh Carbon management
• plan vivocertifying carbon credits

The reason for the request is that I'm hoping to create a web-site which will let people know the environmental impact of flying on commercial flights. Not as a doom and gloom merchant but just so that people are informed.

The idea is to start with all European airports and for the main short-medium haul aircraft, i.e. B737, A320 etc show the total emissions in their CO2 equivalent ( a standard measure ), not specifically the CO2 emissions. This is not for private pilots. I hope that people would appreciate knowing that a weekend trip from London to paris for a couple is the equivalent of driving 2000 km extra in their car per year or something like, that, allowing people to judge themselves the impact of their transport choices and then act accordingly.

I've seen LTO ( landing-Takeoff ) figures put out by airports but don't know enough yet to extrapolate these to be used in my calculations.

The assumptions are:

1. Each flight has 1 LTO cycle involving the 30 km at either end of the flight. 2. Each flight has a cruise part, this distance can be worked out relatively easily. 3. Each aircraft has specs like passenger capacity 4. Each airline produces figures for Load Factor, i.e. % of seats filled on average.

I have 3 and 4 but am missing 1 and 2.

References

1. Number of passengers based on manufacturers specs. Where multiple figures are given due to different configurations, e.g. No first class, single class only, an average figure is taken.
2. PLF-Passenger Load Factor = the ratio of passengers to seats available, i.e. how full is the average flight. For Ryanair/Easyjet ~= 80%, otherwise from 70-80% across the inductry so 75% used in calculation. See IATA for stats concerning this.
