In this episode of the Marex Market Pulse podcast, we explore one of the most urgent shifts in global environmental markets: the transition from CORSIA preparation to full‑scale procurement.
Featuring Scott Thomson, Head of Carbon Trading and Rosie Burton, Environmental Products Trader at CSC Commodities, a division of Marex, this discussion breaks down the realities of CORSIA Phase 1: rising demand, tightening supply and the growing pressure on airlines to act before the market moves.
From eligibility and policy uncertainty, to the accelerating procurement activity we’re now seeing across the sector, this episode offers a clear, practical look at how airlines can secure supply, reduce exposure and gain an early‑mover advantage in an evolving compliance market.
In this episode, we discuss:
- What CORSIA is and who it impacts – a grounded explanation of the scheme and its relevance for international aviation
- Why airlines are now moving into active procurement after years of preparation and monitoring
- The state of CORSIA‑eligible supply – what’s newly tagged, what remains constrained and how fast available volume can be absorbed
- The risks of delaying action, including potential undersupply and late‑cycle bottlenecks as the 2028 retirement deadline approaches
- How policy uncertainty is being managed in contracts (e.g., EU regulation, US participation)
- Market signals from airlines globally, including shifting sentiment, growing demand and emerging procurement practices
- How CSC supports airlines through structured procurement, risk management and a dedicated CORSIA‑aligned project portfolio
Listen now to understand the structural trends shaping the carbon markets and what they mean for aviation in 2026 and beyond.
