Study Reveals Importing US LNG Worse for Climate Than Using Local Coal: New Research Exposes Shocking Emissions Differences

A new study published in Energy Science and Engineering has found that importing fossil gas from the United States to Europe and China for power generation is actually worse for the climate than using local coal. The study, conducted by Robert Howarth from Cornell University, used independent measurements to determine that the emissions produced from US gas production are significantly higher than previously thought.

Previous studies had relied on gas companies’ claims about the environmental impact of their facilities, but Howarth’s research revealed that the emissions from producing US gas are about a third higher than those from burning local coal. This finding challenges the narrative promoted by the gas industry, analysts, and politicians that American gas exports can help countries transition to cleaner energy sources.

Howarth emphasized in the study that ending the use of LNG should be a global priority, as there is no need for it as an interim energy source. He pointed out that the infrastructure required for transporting LNG, including ships, liquefaction plants, and pipelines, involves massive expenditures and contributes to climate change.

One of the key reasons why importing US-produced LNG is worse for the climate than using local coal is the destructive leaks that occur throughout the gas production and transportation process. Methane, a potent greenhouse gas, is a major component of natural gas and leaks into the atmosphere at various stages, from extraction to power generation. The emissions from producing and transporting gas are three times higher than those from producing coal, primarily due to methane leaks.

In the US, the debate over shale gas production and LNG exports has intensified in recent years. President Joe Biden announced a temporary pause on approvals for LNG exports to some countries in response to the evolving understanding of the environmental impact of methane emissions. While climate campaigners welcomed the decision, the gas industry and Republican politicians have pushed back, arguing that gas can play a role in reducing carbon emissions compared to other fossil fuels.

The study’s findings have implications for global energy policies, as some countries have promoted LNG as a transition fuel to diversify gas supplies and reduce reliance on coal. However, the research by Howarth underscores the urgent need to prioritize investments in fossil-fuel-free energy sources to combat climate change effectively.

Overall, the study highlights the complex challenges and trade-offs involved in the transition to cleaner energy sources and the importance of considering the full lifecycle emissions of different fuels in climate policy decisions.
