What you can do
Who's doing it?
Flying is carbon intensive. The combustion of jet fuel releases a lot of carbon emissions. Per-passenger, a single long haul flight can generate more emissions than many people in the world produce in an entire year.
The impact of reducing your air travel depends heavily on how often you fly. If you are a frequent flyer, reducing the amount you fly will almost certainly be the most impactful way you can help fight climate change. For someone who takes one return long haul flight a year, or two return short haul flights, a year of not flying will prevent around 1 tonne of CO2 emissions. See impact calculations.

Facts and further information
A return flight from London to New York generates around 1 tonne of carbon dioxide per passenger - around 10% of the average British person's annual carbon footprint .
It's estimated that only 5%-10% of the world's population fly each year .

Ask the Flying group
There is very little data available on average miles flown per year. The amount that people fly each year varies considerably.
Given the high emissions of a flight, the important thing to remember is - if you fly, reducing the amount you fly is a high impact way of taking action.
For the purposes of this impact assessment we have assumed that a person takes one return long haul flight or two return short haul flights a year. The distance travelled in this assessment is 7,000 miles a year, equivalent to a return flight from London to New York.
Individual CO2 emissions from a return flight from London to New York in economy class  = 986kg = 1 tonne of CO2
By avoiding taking this flight or by double offsetting the emissions, the associated emissions are assumed to be reduced to nil.
The impact therefore of taking no more than one flight a year and double offsetting the emissions when taking that flight can be estimated as preventing 1 tonne of CO2 emissions.
