Environmental sustainability of the aviation industry has received increased public attention over the past years. Rightfully so: commercial aviation emissions account for about ~2% of global CO₂ emissions and about ~12% of total transport emissions [Source]. This does not account for non-CO₂ emissions, which further contribute towards global warming. Therefore, it is the aviation industry’s clear goal to reduce per-passenger/ per-seat as well as total emissions drastically over the coming decades.

A solid emission data base is an essential first step on the path to emission reduction. Thus, we have built a product that helps our customers towards this goal: Skailark’s Airline Sustainability product is the go-to source to measure and benchmark current emissions but also to model future efficiency measures.

Our airline CO₂ emissions index monitors monthly developments of global airlines’ emissions, available publicly and accessible for free. The index displays the CO₂ emissions per available seat kilometer (ASK) by month, normalized against values in January 2019. By selecting the 100% seat density option, CO₂ emissions are benchmarked assuming all aircraft were flying with maximum allowed economy seat density (exist seat limit). Furthermore, the index also monitors total airlines’ emissions.
