Climate Tech Open Call 2026
Open challenge · Hosted by GreenSeal Ventures. Scalable solutions to cut Scope-3 emissions across global supply chains.
About this open call
The brief
GreenSeal Ventures is sourcing scalable solutions that measurably cut Scope-3 emissions — the indirect carbon hidden across global supply chains. They want ideas that work across many suppliers and shipping lanes, not one-off optimisations, and that can show impact within a single pilot.
What they're looking for
Working products and prototypes that measure, attribute, or reduce supply-chain emissions: supplier scoring, smarter sourcing, modal shift, load consolidation, or emissions data that procurement teams can act on. Bonus points for solutions that plug into existing logistics and ERP systems without slowing delivery.
Problem statements
Scope-3 visibility
Most emissions sit in the supply chain, yet few buyers can measure them per supplier or lane. We need data procurement can actually act on.
Impact at scale
Point optimisations don't move the number. Solutions must work across many suppliers and shipping lanes — and show measurable impact within one pilot.
