The airline hopes to introduce the greener fuel choice by 2021.“Adopting this advanced fuel will allow us to reduce CO2 emissions and meet the ambitious sustainable development goals that we have set for the airline,” ANA executive vice president Akihiko Miura said in a statement.ANA and other airlines around the world continue to look for ways to be more sustainable amid a growing backlash about CO2 emissions.
