Is Natural Gas Cleaner Than Coal? It Depends on Leaks—and There's a Huge One in the North Sea

A news report from the first week of the leak. 

Since March 25, the Elgin gas platform off the coast of Scotland has been leaking 7 million cubic feet of gas a day. The natural gas, mostly methane, doesn’t have the dark stain of oil and it hasn’t inspired the news coverage of Deepwater Horizon. But that doesn’t mean it can be ignored.

Like carbon dioxide, methane is a greenhouse gas that traps heat in the Earth’s atmosphere. But methane is much worse: the same amount of methane will have 25 times the warming effect of carbon dioxide over a 100-year period. In the six months that it will take to stop the leak, enough methane would have escaped into the atmosphere to equal the annual global warning impact as 300,000 new cars, according to a recent TIME article.

The Elgin gas leakage is an extreme example of how natural gas exploration and processing is always beset by leaks. After all, the stuff is gas that wants to float away. The TIME piece dissects a recent paper in the Proceedings of the National Academy of Sciences evaluating whether natural gas really is more environmentally friendly than coal. Their answer? It depends, and it partially depends on leaks. Read More
