Yes, ECO Delivery Air offers variants where customers can request a certain % of greenhouse gas (GHG) emissions reductions which will require less than 100% fossil fuel to be replaced by Sustainable Aviation Fuel (SAF). Following the book-and-claim concept, the physical replacement of fossil fuels with SAF is performed by our partner airlines. You can choose the % of greenhouse gas (GHG) emissions reductions starting from 1% and get at least 65% reductions by replacing 100% fossil fuels with SAF.
