Voices from the Summit
“We have so many brilliant people and companies entering the space, and wanting to build this new market. The best thing we can do is to collaborate. Let's build it together.”
— Joona Kunnas, Puro.earth
“We're in quite a paradox. We know we need to scale the market. We want to scale the market with only high quality credits that deserve to be fungible in the market, but we also have created a bit of paralysis.”
— Lizzie Aldrich, Anew
“Every single person here, every single organization that you're a part of needs to be thinking about, how are we going to scale this a lot faster? Because the status quo is not good enough”
— Paul Gambill, Former CEO, Nori
“We massively over optimized around permanence. ... we should have been optimizing on measurability and cost and deliverability and these other benefits. ... It feels like the narrative is kind of coming back to common sense and reality.”
— Jason Aramburu, CEO, Applied Carbon
“I think we're really missing the emergency mindset. And one of the things that everybody in this room should be thinking of is how to get a person with that emergency mindset on your team.”
— Michelle Cobb, Terraformation

1. Sustainable Biomass Sourcing
We source wood from trees killed by wildfire at the location of our projects. This prevents emissions, reduces fire risk, and funds forest recovery.
