Independent SAF & Scope 3 Advisory


Joulec delivers expertise on sustainable aviation fuel (SAF) and environmental attribute markets, built from experience creating a SAF certificate programme within an airline.

Why SAF Is Important

SAF is the key lever for decarbonising air travel. It is safe to use in existing aircraft and can deliver emissions reductions of more than 80% across the full lifecycle. Corporates can claim the Scope 3 reductions using book-and-claim and SAF certificates.

“I spent over two years inside an airline’s SAF programme. I assessed sustainability credentials, negotiated contracts with major corporates, and built an auditable SAF certificate system. Now I help others do the same. ”
— Isobel Campbell, Founder & Principal Advisor
