This study presents an environmental damage analysis of GE90 engine series for take-off, climb-out, approaching and cruise phases to evaluate the emission rates, the global warming potentials (GWP), the global warming potential index (GWPI), the environmental impact (EI), the environmental impact index (EII), the environmental damage cost (EDC) and the environmental damage cost index of exhaust gases emitted from GE90 turbofan engines via standard dual annular combustor (SDAC) and low emission dual annular combustor (LEDAC). The GE90-76B engine has the maximum exhaust emission rate by 3.694 kg/h for SDAC usage. The GE90-92B engine has the maximum NOX emission rate by 755.40 kg/h for SDAC usage and 707.40 kg/h for LEDAC usage. The results can be used by airlines, countries, or companies that use GE90 engine series.
