What share of global CO₂ emissions come from aviation?
Non-CO 2 climate impacts mean aviation accounts for around 4% of global warming to date. While aviation accounts for around 2.5% of global CO 2 emissions, its overall contribution to climate change is higher.. Along with emitting CO 2 from burning fuel, planes also affect the concentration of other atmospheric gases and pollutants. They generate a short-term increase …
