The Times, 24 October 2019:
Sir, The National Audit Office should be congratulated for its timely report examining the financial and environmental costs of fracking (News, Oct 23). The rationale for developing yet another fossil fuel is based on the erroneous belief that gas is better than coal from a climate perspective. But this is only true if fugitive emissions of methane are ignored. The high global warming potential of methane (85 times greater than CO2 over 20 years) means that releases amounting to 2 per cent of production are sufficient to cancel out the benefits of burning gas instead of coal. Satellite measurements over shale fields in North America have indicated losses in excess of 5 per cent.
Even conventional gas production incurs losses of about 1.5 per cent. If that gas is then liquefied, which is itself a very energy intensive process, then gas still has no advantage over coal. The government should abandon its misguided support of fracking.
