Do any of these apply to you?
✅Low hanging fruit makes my mouth water.
✅I think I'm contrail curious.
✅I'm just looking for a short-term fix.

If so, join this @theicct.org webinar about our new aviation decarbonization study covering contrails.

Vought told House Republicans the layoffs will be "consequential."

At that point, the cooling effects of cutting SLCPs are overpowered by accumulating atmospheric CO2 (Fig 16). This illustrates the value of an aviation Full Breakthrough that uses near-term SLCP cuts to buy time to mature new technologies to reduce GHGs. (END) theicct.org/publication/...

Dan Rutherford @rutherdan.bsky.social · 12d

One might ask: if the SLCP Forward scenario holds aviation's share of WB2D warming constant through 2050 without additional CO2 controls, why do we say that net-zero CO2 is still necessary? The answer: we still care about the Earth after 2050!/

1

Dan Rutherford @rutherdan.bsky.social · 12d

The Full Breakthrough scenario combines these two scenarios and cuts aviation's share of warming in half (2%) under 1.7°C and holds it constant (4%) even under the very challenging 1.5°C scenario. Not too shabby for a "hard to abate" sector!/

Dan Rutherford @rutherdan.bsky.social · 12d

The SLCP Forward scenario, which forgoes additional CO2 reduction in favor of aggressive cuts in SLCPs, cuts that down to its historical share (4%)./

1

Dan Rutherford @rutherdan.bsky.social · 12d

In contrast, the GHG Forward scenario applies maximum feasible reductions in CO₂ through sustainable aviation fuels (SAF), zero-emission planes, and improved fuel efficiency to reduce that share to 9%. Still, more than a doubling of aviation's historical share./

Dan Rutherford @rutherdan.bsky.social · 12d

Table 12 compares aviation’s projected warming from 2025 to 2050 under different scenarios and how much of the remaining global temperature budget each would consume. Our Current Commitments scenario envisions a quadrupling (to 15%) of aviation's share of 1.7C temperature budget./

1 1

Dan Rutherford @rutherdan.bsky.social · 12d

We estimate that airlines contributed about 0.058°C in 2025, or 4% of anthropogenic warming. Let's take that 4% as a ceiling for future warming, on the assumption that airlines shouldn't increase their share of emissions over time./

Dan Rutherford @rutherdan.bsky.social · 12d

Recall that the Paris Agreement aims to keep global warming well below 2°C (WB2D, modeled here as 1.7°C), with efforts to limit it to 1.5°C. With only about 0.34°C of the 1.7°C budget left for all sectors, there's not much room to spare./ essd.copernicus.org/articles/17/...

Our recent @theicct.org net zero aviation roadmap concludes that a 2050 net-zero CO₂ target is necessary, but not sufficient, to align aviation with the Paris Agreement. Additional measures to address short-lived climate pollutants (SLCPs), especially contrail-cirrus, are also needed. But why? (🧵)

Contrail formation is driven by naphthalene content, which is zero for SAFs. So, while the GHG intensity varies widely by feedstock, we don’t expect contrail properties to vary between different SAF blends.

Dan Rutherford @rutherdan.bsky.social · 13d

So SAFs provide both short and long-term climate benefits, albeit at a high cost compared to alternatives like hydrotreating fossil jet fuel. All this and more in the full report. (END)

To comply with the Paris agreement, aviation decarbonization strategies need to include controls on short-lived climate pollutants to complement greenhouse gas mitigation.
