Why is aviation bad for the environment?
Introduction. Aircraft emit a range of greenhouse gases throughout the different stages of flight. Aircraft are unique in that they emit gases directly into the higher levels of the atmosphere. Research suggests that gases can have different effects when emitted at this altitude relative to emission at ground level..
Will aviation be responsible for 22% of carbon emissions by 2050?
If aviation were unmitigated, it could be responsible for 22% of global emissions by 2050. While the current path will see global temperatures rise 2.4\xb0C, this net-zero roadmap would get the industry back on track to deliver on a 1.5\xb0C target..

Aviation carbon emissions
Type of fuel which have no net greenhouse gas emissions
Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO2) as a feedstock. Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels, which are made by chemically hydrogenating carbon dioxide, and biofuels, which are produced using natural CO2-consuming processes like photosynthesis.
Carbon emission trading
An approach to limit climate change by creating a market with limited allowances for CO2 emissions
Carbon emission trading (also called emission trading scheme (ETS) or cap and trade) is a type of emission trading scheme designed for carbon dioxide (CO2) and other greenhouse gases (GHG). It is a form of carbon pricing. Its purpose is to limit climate change by creating a market with limited allowances for emissions. This can lower competitiveness of fossil fuels and accelerate investments into low carbon sources of energy such as wind power and photovoltaics. Fossil fuels are the main driver for climate change. They account for 89% of all CO2 emissions and 68% of all GHG emissions.
The carbon footprint (or greenhouse gas footprint) serves as
Concept to quantify greenhouse gas emissions from activities or products
The carbon footprint (or greenhouse gas footprint) serves as an indicator to compare the total amount of greenhouse gases emitted from an activity, product, company or country. Carbon footprints are usually reported in tons of emissions (CO2-equivalent) per unit of comparison; such as per year, person, kg protein, km travelled and alike. For a product, its carbon footprint includes the emissions for the entire life cycle from the production along the supply chain to its final consumption and disposal. Similarly for an organization, its carbon footprint includes the direct as well as the indirect emissions caused by the organization (called Scope 1, 2 and 3 in the Greenhouse Gas Protocol that is used for carbon accounting of organizations). Several methodologies and online tools exist to calculate the carbon footprint, depending on whether the focus is on a country, organization, product or individual person. For example, the carbon footprint of a product could help consumers decide which product to buy if they want to be climate aware. In the context of climate change mitigation activities, the carbon footprint can help distinguish those economic activities with a high footprint from those with a low footprint. In other words, the carbon footprint concept allows everyone to make comparisons between the climate-relevant impacts of individuals, products, companies, countries. In doing so, it helps to devise strategies and priorities for reducing the carbon footprint.
Carbon offsets and credits
Carbon dioxide reduction scheme
A carbon offset is a reduction or removal of emissions of carbon dioxide or other greenhouse gases made in order to compensate for emissions made elsewhere. A carbon credit or offset credit is a transferrable financial instrument (i.e. a derivative of an underlying commodity) certified by governments or independent certification bodies to represent an emission reduction that can then be bought or sold. Both offsets and credits are measured in tonnes of carbon dioxide-equivalent (CO2e). One carbon offset or credit represents the reduction or removal of one ton of carbon dioxide or its equivalent in other greenhouse gases.
