“Credits in the current market might represent anywhere from 10 years of carbon storage to, you know, maybe a couple of decades or at the very, very high end. In forests, but on soils, a hundred years. So you're talking about a really different time scale than the emissions you're trying to offset.”

Chay: Soil carbon protocols broadly lack measurement, permanence, and additionality
“We did a really interesting review of all of the protocols, so all of the crediting rules that are currently used to issue credits to soil carbon in collaboration with Jane Zelikova, and basically, you know, you have these PDF documents that, maybe you have mu…”
Chay: Treating uncalibrated models like sampled soil creates a race to the bottom
“If you're in a market and everything looks like a ton, so I could take any of these approaches and get tons that I can sell, and they look the same in the market you really result in a race to the bottom. It's way easier to not sample anything and get some ton…”
Chay: California depleted its 100-year forest carbon wildfire buffer in 10 years
“Yeah, it's not all the way gone, but we've, we have used up all of the credits that were meant to protect against forest fires for the next 100 years in the first 10 years of the program.”
Chay: Soil carbon additionality screens function primarily as box-checking exercises
“Across the board, you see additionality screens that, in my opinion, look a lot more like box checking exercises and a lot less like, kind of, a rigorous questioning around how these dollars enable new practices.”
Chay: Ton-year accounting fails to reflect the physical reality of temporary storage
“There are different methods, but I would lead by saying, I really don't think we should do it. I don't think tenure accounting represents the physicality of temporary carbon storage in a meaningful way.”
