Biogenic emissions: high
Web1.Introduction. Global CO 2 emissions from aviation amounted to 1.9% of the total green-house gas (GHG) emissions in 2024 (Ritchie, 2024).However, owing to the presence of the so-called high-altitude effect, aviation fuels create an additional global warming effect, and aviation is therefore responsible for 3.5% of the effective radiative forcing (Lee et al., … WebMar 31, 2024 · Biogenic Emission Sources. Biogenic emission sources are emissions that come from natural sources, and need to be accounted for in photochemical grid models, as most types are widespread and ubiquitous contributors to background air …
