From academic estimates to ground truth: how Rystad Energy is helping shape global LNG emissions policy in International Shipping News 16/06/2026 SEA-LNG used Rystad Energy’s vessel-level emissions tracking and LNG trade flow data to produce a landmark white paper, the findings of which were submitted to the International Maritime Organization and endorsed by Norway and South Korea Highlights Cargo-level precision: Rystad Energy tracked emissions for every LNG cargo delivered globally, vessel by vessel, from production to point of use Backed by governments: Norway and South Korea endorsed the findings for submission to the IMO to help set allowable emissions factors for marine fuels Three data streams, one study: Shipping, trade flows and asset-level emissions profiles were combined in a single analysis, a capability no other provider could offer The challenge: replacing academic estimates with real-world data Existing well-to-tank emissions studies for LNG relied heavily on academic literature, with researchers citing earlier papers rather than drawing on live, asset-level data. This approach produced estimates that failed to capture regional variation, vessel-by-vessel differences or the actual conditions across global supply chains. SEA-LNG is focused on advancing LNG as a marine fuel needed a more accurate, defensible view of well-to-tank emissions to support its advocacy work. Their goal in this project was to provide a ground-truth account of LNG emissions across the full value chain: from production and liquefaction through to shipping and bunkering, at a level of granularity that could withstand technical scrutiny from engineers, regulators and policymakers. Without access to integrated, asset-level data spanning the entire LNG value chain, producing a study credible enough for submission to the International Maritime Organization was not possible. Partnering with Rystad Energy: full value chain tracking, cargo by cargo SEA-LNG worked with Rystad Energy to p
