Despite the evidence of significant potential risks presented in a recent report by the Tyndall Centre, the British government says it will forge ahead with plans for shale gas development in the UK. The Tyndall Centre’s study, “Shale gas: a provisional assessment of climate change and environmental impacts” [PDF], urged the UK to place a moratorium on shale gas in light of serious risks associated with shale gas development, including the contamination of ground and surface waters, the expected net increase of CO2 emissions, and substantial monetary costs which could delay major investments in clean energy technologies.
Shale gas extraction involves drilling into shale formations followed by a rock fracturing process which uses heavily polluting chemicals. Especially in the US with the introduction of drilling “refinements” known as hydrofracturing or “fracking,” shale gas extraction has become highly divisive, and ever more popular among natural gas producers (making up nearly 10% of production by some estimates). The significant water contamination and public health risks associated with shale gas are well documented in last year’s “Gasland” film.
Paul Monaghan, the Co-operative’s head of sustainability describes shale gas as “like tar sands in your backyard, both in terms of local pollution and in terms of carbon emissions.”
