Consolidated discussion of life cycle assessment on algae based aviation fuel in combustion emissions on the basis of engine type and related aircraft was conducted by comparing with conventional jet fuel. Using the GREET （the greenhouse gases

regulated emissions

and energy use in transportation） model

passenger aircrafts were divided into six classes including single aisle

small twin aisle

large twin aisle

large quad

regional jet

and business jet. Each aircraft class was characterized by its average payload

potential flight range

and fuel consumption and emissions during landing

takeoff

taxiing

climbing referred to in the database of NASA-AAFEX

EASA

and CAAC. Also the emissions and energy input were discussed. The pump-to-wheel stage of algae based jet fuel in large twin aisle aircraft shows the least amount of greenhouse gases emission at 0.2351g/(kg·km) because larger aircraft has lower greenhouse gases emissions values than smaller aircraft due to higher engine efficiency and higher payload

however single aisle aircraft appears to be more sensitive to greenhouse gases emission in flight range than larger aircraft due to higher contribution of landing and takeoff.
