Aviation emissions are not on a trajectory consistent with Paris Climate Agreement goals.
We evaluate the extent to which fuel pathways—synthetic fuels from biomass, synthetic fuels …

Given the urgency to decarbonize global energy systems, governments and industry are
moving ahead with efforts to increase deployment of hydrogen technologies, infrastructure …

To meet ambitious climate targets, the aviation sector needs to neutralize CO2 emissions
and reduce non-CO2 climatic effects. Despite being responsible for approximately two-thirds …

The sustained growth of global aviation emissions has highlighted the urgent need for using
Sustainable Aviation Fuels (SAFs) to replace traditional aviation fuels to mitigate emissions …

Aviation NO x emissions have not only an impact on global climate by changing ozone and
methane levels but also contribute to deteriorate local air quality. In order to properly assess …

Hydrogen is quickly gaining attention as a “clean” fuel that can support a transition to a
decarbonized energy system. 5 Given the urgency to decarbonize global energy systems …

Steps to limit greenhouse gas emissions, including putting a “price” on emissions, can be
undertaken in a variety of ways, and these policies are associated with different terminology …

The effects of aviation on the Earth's atmosphere are mainly focused on greenhouse gases
emissions, since CO 2 and CH 4 emissions are an important part of climate change …

Assessing mitigation strategies for aviation is a critical issue for the aviation stakeholders,
while the debate continues on the most appropriate CO2-equivalence metrics to address …
