Ulrike Ziegler explains how Sustainable Aviation Intelligence is helping Impact on the path to Net Zero.

Impact on Sustainable Aviation e.V. is a non-profit association supported by more than 30 leading aviation lenders, aircraft lessors and industry stakeholders, working to accelerate aviation’s transition to a more sustainable future.
Led by Ulrike Ziegler, Impact brings together airlines, lessors, banks and wider aviation finance participants to build knowledge, foster industry dialogue and support more transparent, standardised approaches to emissions reporting.
Its work is focused on helping the aviation finance community better understand the complexity of aviation’s transition, make informed capital allocation decisions and assess the role of sustainable finance tools, including sustainability-linked loans, bonds, SAF, fleet renewal and carbon removal.
Sustainable aviation is a fast-moving and highly complex space. For Impact, staying informed means tracking developments across regulation, sustainable finance, SAF, emissions reporting, airline transition strategies and emerging market standards.
With a large member base and a small internal team, Impact needed a reliable way to stay on top of developments without having to monitor multiple fragmented sources.
Key challenges included:
As Ulrike explains:
“That was the big challenge, going to that one source that has all the right data.”
Impact uses SAVi: Sustainable Aviation Intelligence as a central source of sustainability intelligence for aviation finance.
SAVi helps Ulrike and the Impact team stay informed on weekly developments, access executive summaries, follow key market updates and identify the issues that require closer attention.
“If I’m not able to follow up on news throughout the week, I look at SAVi and I get all the relevant information. I get the insights.”
The SAVi Five newsletter is particularly valuable, providing weekly takeaways, links to relevant materials and concise analysis of the most important developments across sustainable aviation.
Impact also uses SAVi to track sustainability-linked finance activity, including loans, bonds, key participants and the KPIs being used in transactions. This supports Impact’s work in educating members on how sustainable finance products are
developing and where gaps or inconsistencies remain.
“Every time I talk on the development of sustainability-linked loan products or bond products, I would always refer back to SAVi because it has all the information that I need.”
By using SAVi, Impact is able to access trusted, aviation-specific sustainability intelligence from one reliable source, saving time while strengthening the quality of insight it can bring to members.
Key areas of value include:
For Impact, SAVi provides both the breadth and depth needed to stay informed in a fast-moving sector.
“How many sources do you want to tap? You want to have the one that’s reliable, that’s to the point, and that’s always really on top of things.”
“SAVi is my go-to source. It’s reliable, trustworthy, and on top of things — the one source you need.”
