About Project Nahoonai

Project Nahoonai is Cielo’s flagship commercial-scale SAF project under development in Prince George, British Columbia. The project converts sustainable forestry residues and waste woody materials into a high-value, low-carbon aviation fuel. Project Nahoonai is being designed with integrated carbon capture and storage (“CCS”), capturing the biogenic CO₂ generated during the conversion process and permanently storing it, resulting in a carbon-negative SAF product positioned as a compliance fuel under British Columbia’s Low Carbon Fuel Standard and Canada’s Clean Fuel Regulations. Under the LCFS and CFR, each tonne of CO₂ captured and permanently stored generates additional credit value, materially strengthening the project’s economics relative to conventional SAF pathways.

Project Nahoonai is a majority Indigenous-owned initiative, developed in partnership with Tano T’enneh Enterprises, the economic development arm of the Lheidli T’enneh First Nation, on whose traditional territory the project is being advanced. The name Nahoonai is a Dakelh word selected in consultation with and approved by the Lheidli T’enneh First Nation.
