On 5-6 February 2026, the Impact Finance Forum brought together emerging fund managers, investors, and ecosystem builders in Luxembourg. Organised by Accelerating Impact — the team behind the International Climate Finance Accelerator (ICFA) and International Social Finance Accelerator (ISFA) — the forum is a key gathering for the European impact finance community.
This year’s edition focused on moving from narrative to implementation, with sessions on biodiversity finance, AI for good, and the role of SDGs in private markets. Tau20’s Dr. Mirko Hirschmann, a postdoc at University of Luxembourg, led a hands-on workshop on GHG impact measurement, designed specifically for emerging fund managers. Participants worked through four live cases:
- CAURUS Technologies — ultra-efficient aerial firefighting
- WEO — satellite-powered AI insights for climate-resilient cities
- Coffeefrom — bioplastics and tableware made from coffee grounds
- Zubi — an impact VC portfolio
For each case, the group identified GHG benchmarks, sized market potential, and selected measurement methods — then drafted a one-year impact measurement plan using AI tools.
“Inspiring to see in which diverse areas impact investors engage and to learn how impact assessment approaches vary in scope and depth.”

Impact measurement remains an ongoing challenge across the sector — alongside fundraising and LP alignment. This is exactly why Tau20 is committed to supporting both impact founders and investors: giving founders investor-grade evidence, and giving fund managers a standardised signal they can trust. Sessions like this one are part of how we build that shared language across the ecosystem.
