2030 Shipping Goal At Risk Despite Historic Progress Made By IMO: New Report
Summary
The new 2025 progress report, produced by the UCL Energy Institute with the Global Maritime Forum’s Getting to Zero Coalition and the Climate High-Level Champions, finds the shipping sector is still off track to meet the IMO’s 2030 ambition of 5–10% of international shipping fuel coming from scalable zero-emission fuels (SZEF).
While technology and supply pipelines (methanol and ammonia propulsion, growing pilot projects) are advancing, weak demand signals and stalled finance threaten to leave the sector short of the critical 2030 tipping point. The IMO’s Net Zero Framework is a major diplomatic achievement, but key implementation details and incentives are still being negotiated and will determine whether the 2030 target remains plausible.
Key Points
- The industry is not yet on track to reach the 5–10% SZEF share by 2030; current projections indicate a substantial shortfall.
- Technology readiness has improved: methanol engines are commercial, ammonia engines are in late testing, and fuel pilots are expanding.
- Supply pipeline could cover between c.32% and 134% of projected SZEF needs — large uncertainty remains.
- Demand is off track: the present orderbook will deliver roughly 37% of the SZEF-capable capacity needed by 2030, implying a shortfall of about 9 million tonnes fuel oil equivalent (around 400 large container ships).
- Finance is lagging: capital still flows mainly to conventional fossil vessels; clearer policy signals are needed to unlock private investment.
- Policy progress is partial: IMO’s Net Zero Framework is important, but critical details and incentives remain to be finalised and adopted by 2027.
- The report urges three priority actions: support a robust IMO reward mechanism prioritising SZEF, raise awareness of risks to non-SZEF assets, and use national/sub-global policies to fill gaps.
- Failing the 5% threshold by 2030 risks undermining the 2050 net-zero goal and could leave assets stranded as global trade grows.
Context and Relevance
Shipping accounts for roughly 3% of global greenhouse gas emissions — more than many individual countries — so its decarbonisation is strategically important. The 5% SZEF share by 2030 is treated as the ‘critical mass’ needed to mature infrastructure, supply chains and investment flows so zero-emission fuels can scale exponentially thereafter.
For shipowners, yards, financiers and policymakers the report is a practical wake-up call: technology alone won’t deliver the transition. Alignment across demand, supply, finance and regulation is essential. Without coordinated incentives and clearer policy design from the IMO and national actors, investments may continue to favour conventional ships and slow the shift to SZEF.
Author
Punchy: This report is a loud, clear nudge — the diplomatic win at the IMO was necessary but not sufficient. Read this if you act on or invest in shipping decarbonisation; it flags where momentum is real and where it risks stalling.
Why should I read this?
Quick take: tech is ready, supply is growing, but demand and money aren’t following. We’ve skimmed the heavy stuff for you — read this if you want the one-paragraph picture of where shipping decarbonisation actually stands and what needs to change fast.
