In an editorial for this week’s British Medical Journal, reported on Drill or Drop website, David McCoy and Patrick Saunders cautioned that fracking might have an adverse impact on climate change stating:
“Although we can’t be certain about the scale of harm that shale gas production will bring to local communities and the immediate environment, it will exacerbate climate change. And on these grounds alone, the risks clearly and considerably outweigh any possible benefits.”
Their concerns related to methane leakage into the atmosphere. With leakage rates high from production and supply pipelines , the impact on climate change would be considerable with methane being 86 times more potent a greenhouse gas than CO2 over a 20 year period GWP20.
