IEA: Global LNG supply chain emissions hit 350 million tons of CO2 per year

Global liquefied natural gas supply chains produce approximately 350 million tons of carbon dioxide equivalent annually, comparable to the yearly emissions of Italy; however, these emissions could be reduced by 60% for $100 billion, according to Bloomberg, referencing a report from the International Energy Agency (IEA).

Simultaneously, merely decreasing methane leaks could lower yearly emissions by nearly 90 million tons of CO2 equivalent, representing 25% of overall LNG emissions, with around half of this decrease achieved at no net expense.

Applying this proposal worldwide would increase the cost of supplying LNG from current LNG facilities by roughly $1 per MBtu.

The IEA is confident that emissions can be decreased. The proposal highlights multiple affordable alternatives that would greatly lessen the climate effects of LNG. The report states that, on average, LNG generates roughly 25% fewer emissions than coal worldwide. The authors emphasize that natural gas producers and LNG operators must adopt a more ambitious stance in cutting their emissions.

The agency states that “the emissions intensity of LNG supplies is approximately 66% greater than that of traditional natural gas.”
