The 2025 reporting year closes 31 December 2025; pooling submissions due 30 April 2026. Penalty: EUR 2,400 per tonne VLSFO-equivalent. For a 1,000-vessel European liner fleet running 3% over the cap, the modelled penalty is roughly EUR 178M before pooling relief. https://ecofreight.co/blog/imo-mepc-82-outcomes https://ecofreight.co/blog/imo-mepc-82-outcomes Sat, 23 May 2026 00:00:00 +0000 Muhammad Ali muhammad-ali@ecofreight.co (Muhammad Ali) regulations MEPC 82 (Sept-Oct 2024) consolidated the mid-term measures debate; MEPC 83 (April 2025) formally adopted the combined GHG Fuel Standard plus remedial unit price framework. What is confirmed, what is still draft text, and the realistic 2026-2030 implementation timeline. https://ecofreight.co/blog/slow-steaming-actual-savings https://ecofreight.co/blog/slow-steaming-actual-savings Sat, 23 May 2026 00:00:00 +0000 Muhammad Ali muhammad-ali@ecofreight.co (Muhammad Ali) logistics The cubic speed-fuel relationship derived from naval hydrodynamics. 8,500 TEU container ship dropping from 22 to 17 knots saves 43% of voyage fuel but costs USD 235,000 in inventory carry per voyage. The break-even bunker price, and where slow steaming pays vs where it breaks. https://ecofreight.co/blog/saf-supply-math https://ecofreight.co/blog/saf-supply-math Sat, 23 May 2026 00:00:00 +0000 Yash Dhote yash-dhote@ecofreight.co (Yash Dhote) sustainability SAF sits at 0.3% of global jet fuel supply. ReFuelEU mandates 2% by 2025, 6% by 2030, 70% by 2050. Cost per tCO2-avoided: USD 300-800 for HEFA, USD 800-1,400 for synthetic. The honest take: SAF mandates are real, but SAF will not be the dominant aviation freight decarbonisation lever before 2035. https://ecofreight.co/blog/verra-redd-credit-quality-review https://ecofreight.co/blog/verra-redd-credit-quality-review Sat, 23 May 2026 00:00:00 +0000 Yash Dhote yash-dhote@ecofreight.co (Yash Dhote) sustainability The January 2023 Guardian / Die Zeit / SourceMaterial investigation found ~90% of audited REDD+ credits did not represent real reductions. Verra responded with new methodology VM0048. What VM0048 actually changes, what it does not, and what freight operators should buy if they want a credible offset claim. https://ecofreight.co/blog/api-vs-sdk-when-to-use-which https://ecofreight.co/blog/api-vs-sdk-when-to-use-which Sat, 23 May 2026 00:00:00 +0000 Ahmed Shabib ahmed-shabib@ecofreight.co (Ahmed Shabib) technology Most vendors push SDKs because they make better case studies. For many freight integration patterns the raw REST API is what you actually want. When SDK is the right call, when it is not, and the six questions to ask any emissions vendor before signing. https://ecofreight.co/blog/glec-vs-defra-emission-factors https://ecofreight.co/blog/glec-vs-defra-emission-factors Sat, 23 May 2026 00:00:00 +0000 Mayur Rawte mayur-rawte@ecofreight.co (Mayur Rawte) methodology DEFRA is simpler for UK-only SECR reporting. GLEC is the right base for any lane that crosses a border or any shipper that reports to CDP or CSRD. The 8% gap on UK heavy truck, the LNG and biofuel and reefer divergences, and my honest opinion on which way to point a calculator. https://ecofreight.co/blog/glec-vs-iso-14083 https://ecofreight.co/blog/glec-vs-iso-14083 Sat, 23 May 2026 00:00:00 +0000 Mayur Rawte mayur-rawte@ecofreight.co (Mayur Rawte) methodology GLEC is the factor table. ISO 14083 is the methodology. They sit on top of each other, not next to each other. What each one specifies, where they overlap, and what changes on the same shipment when you swap the methodology stack underneath the GLEC factors. https://ecofreight.co/blog/glec-v3-0-vs-v3-2 https://ecofreight.co/blog/glec-v3-0-vs-v3-2 Sat, 23 May 2026 00:00:00 +0000 Mayur Rawte mayur-rawte@ecofreight.co (Mayur Rawte) methodology If your calculator is on v3.0, what do your numbers do when you upgrade to v3.2? Same Shanghai-Rotterdam shipment in both versions, the percent move by mode, when to migrate, and whether to restate the prior year. https://ecofreight.co/blog/freight-emissions-api-comparison https://ecofreight.co/blog/freight-emissions-api-comparison Sat, 23 May 2026 00:00:00 +0000 Ahmed Shabib ahmed-shabib@ecofreight.co (Ahmed Shabib) technology I work on EcoFreight.

EU importers of steel, aluminium, cement, fertiliser, hydrogen, and electricity now buy carbon certificates against embedded emissions — including the freight leg.

A 3,000-TEU feeder emits about 12 g. Two orders of magnitude apart.

The honest number is 10-15% on Asia-Europe — not 23%, not 50%.

An API-based approach gives you per-shipment numbers in milliseconds. We compare the two workflows and what switches when you make the move.
