Assessing Emissions from LNG Supply and Abatement Options

This report estimates emissions along the liquefied natural gas (LNG) supply chain, covering production, processing, transmission, liquefaction, shipping, and regasification. The analysis excludes emissions associated with exploration, onward transport after regasification, and combustion of natural gas. It evaluates approximately 350 upstream assets across 22 countries, 45 liquefaction terminals, and 220 regasification terminals in 50 countries, tracking over 750 ships carrying LNG on around 7,000 round-trip journeys annually. The report compiles public and proprietary data to assess the entire LNG supply chain journey, from wellhead to regasification. The total greenhouse gas emissions from the LNG supply chain are estimated at around 350 million tonnes of carbon dioxide equivalent (Mt CO2-eq), with approximately 70% as CO2 emissions and 30% as methane emissions. The report also discusses mitigation options to reduce emissions and improve efficiency across the LNG supply chain.
