aviation

“Steel is like eight percent of global carbon emissions. It's three times aviation.”

“Add on the additional warming impacts of aircraft contrails, and estimates are that aviation contributes ultimately something like three and a half percent of total anthropogenic warming.”

“So aviation represents somewhere in the range of two to three percent of global greenhouse gas emissions. If it were a country, its emissions would rank around sixth in the world, somewhere between Japan and Germany.”

“In 2050, the amount of electricity that would be required to decarbonize aviation is the entire renewable energy production today. So all of the energy, renewable energy that is produced today could be used up in aviation alone.”

“So this is like aviation, but harder because there's not as much money.”

“Steel, aluminum, cement, chemicals, aviation, shipping, and trucking. Add them up, and they represent about a third of global greenhouse gas emissions, and they're the sectors where the existing, fully commercialized, mature, and ready-to-deploy technology wil…”

“And I think it is going to continue to be the case that Jet A is going to be the winner, and synthetic fuels of all stripes still have to make Jet A.”

“And so I think most people who've taken a serious look at aviation and even considering major step changes in battery density, let's say a three times improvement in density, From where we are today, there's just a vanishingly small share of total flight miles…”

“In aviation beyond short haul, I actually think it seems pretty clear the path we're headed down, which is a path of blending, of largely biosaf, followed eventually by drop in fuels, probably e-fuels someday in the future.”

“I think, you know, the future of maritime, it's not going to be single fuel. So we're not going to, for example, move into one single fuel. I think, you know, as a contrast to aviation, where I think there's a convergence that we need sustainable aviation fuel…”

“Refrigerants are, in aggregate, actually a huge source of global greenhouse gas emissions from a climate impact standpoint. They are roughly on par with aviation, which is big.”
