Liquefied Natural Gas (LNG) lacks a clean and eco-friendly reputation

Liquefied Natural Gas (LNG) has been touted as a cleaner alternative to coal due to its lower carbon dioxide emissions during combustion. However, a closer look at its environmental impact reveals a more complex picture.

### Greenhouse Gas Emissions

LNG generates approximately 25% fewer greenhouse gas emissions than coal on average. Yet, methane leaks in the supply chain can significantly increase its climate impact. Methane, a potent greenhouse gas, is responsible for substantial global warming effects and is the main component of LNG, making up more than 90%.

One study concluded that LNG has a 33% larger greenhouse gas footprint than coal over a 20-year timeline, primarily due to methane leakage issues. Conversely, other studies argue that LNG can be a cleaner option if emissions are effectively managed.

### Specific Concerns

The energy-intensive processes of liquefying and transporting LNG add to its overall carbon footprint. Methane leaks during production, transport, and storage can lead to significant emissions, with methane being around 85 times more powerful than carbon dioxide at trapping heat over a 20-year period.

The European Union classifies natural gas-powered electricity as green energy in certain contexts, but this classification has been a subject of debate. The US, the world's largest exporter of LNG, has its largest LNG export facility in the Gulf Coast state of Louisiana, which has recently rebranded LNG as "green" energy.

### Addressing Environmental Concerns

Addressing the environmental concerns surrounding LNG requires a multi-faceted approach. Implementing methane abatement technologies and powering liquefaction plants with renewable energy could help reduce emissions significantly. Strengthening regulations to ensure consistent standards across the LNG supply chain can also help mitigate environmental impacts.

Raising awareness about the complexities of LNG's environmental impact is crucial for informed decision-making regarding its role in future energy systems. Some experts argue that LNG has no place in a clean energy future, while others believe it can play a role if emissions are effectively managed.

In recent years, European countries have been building LNG terminals to ship gas primarily from the US, but also Qatar and Algeria. However, the European Union's commitment to phase out imports from Russia by 2027 has resulted in a decrease in US LNG imports, with a drop of 19% in 2024 from the highs of the previous year. Despite this, Russian supplies entering the bloc in 2024 went up by 18%.

As the world transitions towards cleaner energy sources, the role of LNG in this transition remains a topic of ongoing debate. The need for technological improvements, strong regulations, and public education will be crucial in determining LNG's future in the energy sector.

1. The environment and climate-change are key factors in the debate over LNG as a cleaner alternative to coal.
