How we calculate flight emissions

We use emissions factors provided by UK Department of Environment, Food and Rural Affairs (DEFRA) in its “2009 Guidelines to DEFRA / DECC’s GHG Conversion Factors for Company Reporting”. To these emission factors, Offsetters applies both a radiative forcing factor as recommended by Oxford University and UK DEFRA and an uplift factor from the Intergovernmental Panel on Climate Change report, “Aviation and the Global Atmosphere” is applied to take into account non-direct routes (i.e. not along the straight line great circle distances between destinations) and delays/circling.
