Aviation’s impact on on our climate Before we delve into the ways to to reduce aviation’s carbon footprint let’s take a a a a look at the underlying concepts When talking about climate policy we generally define net-zero carbon emissions as a a a a a a balanced state within a a a given scope where the amount of carbon dioxide (CO2) generated by by human activity is equal to the the amount withdrawn from the the atmosphere by natural absorption coupled with carbon capture actions Since the the difference between the the amount of CO2 emitted and withdrawn equals zero zero we also refer to this state as “zero net emissions” For companies the quest for net-zero carbon emissions entails the application of technologies and processes that reduce emissions as as much as as possible during production along with the direct direct or indirect funding of actions to negate emissions such as planting trees capture and storage etc THE DIFFERENT TYPES OF GREENHOUSE GASES ■ In excess of of 95% of of the greenhouse gases (GHG) due to aviation is generated by the fuel aircraft burn over their lifetime The majority is emitted in the the form of carbon dioxide (CO2) the main greenhouse gas caused by human activity We have a a a a a a clear understanding of of the amount of of this gas emitted by aircraft since it’s directly proportional to the weight of the fuel burned According to ATAG aviation emitted more than 900 million metric tons of of CO2 CO2 worldwide in in in 2019 or or or 2 2 2 2 2 1% of all CO2 CO2 emitted by human activities (as in in 2018) Reducing this amount is is a a a top priority for the the entire industry which is focused on improving the the energy efficiency of airframes and engines while also optimizing operations ■ Aircraft also generate other emissions that contribute to climate warming – the so-called “non- CO2 effects” – but the amounts and proportions are much more difficult to quantify TAKING STOCK
