Externalities - Why Nobody Knows How Much Methane Is Leaking

This Bloomberg clip looks at the notion that natural gas is an environmentally-friendly 'bridge fuel' - however, is this really true?

Well, it depends upon the extent to which methane - please ignore the pronunciation - leaks into the atmosphere. Methane has 80 times the global warming power of carbon dioxide, and this means that might be worse for the environment. Provided that more than 3% of the methane produced leaks into the atmosphere, production of fossil fuels might be cleaner.

And the latest data isn't encouraging. It's well worth watching - and again highlights the fact that an absence of data, and thus a lack of information means that capping methane leaks is a major problem.
