Burning liquified natural gas produces a significant amount of emissions

Burning liquefied natural gas (LNG) produces a significant amount of emissions, contributing to environmental and climate challenges. Although LNG is often promoted as a cleaner alternative to other fossil fuels such as coal and oil, it still generates substantial quantities of carbon dioxide when combusted — cutting emissions by less than half compared to bunker fuels 1. Moreover, the production and transportation of LNG often cause methane leaks 2. A 2024 study from the International Council on Clean Transportation found that methane leaks from LNG-powered ships averaged around 6.4% 2.
