We finally launched the Practitioner’s Guide 1.0 for “The Milestone Concept” – a simple, progress-based framework – scientifically vetted – to make decarbonization visible, credible, and useful for strategy and finance.

Developed by impact the scientifically vetted Milestone Concept cuts through reporting complexity by focusing on what’s actually happening now, not distant, assumption-heavy targets.

HOW IT WORKS

• Built on just two readily available data points
• Lower reporting burden, higher comparability
• Designed to tackle greenwashing by showing incremental progress
• Supports airlines, lessors, lenders & investors with a shared view of transition progress

Whether through fleet renewal, SAF uptake, or other levers, this approach turns operational steps into clear, decision-useful metrics – without recalibrating long-term pathways every year.

The guide is live now and will evolve as the industry does, incorporating new themes like non-CO₂ effects and removals.
