A report produced by Talk Fracking for the Ecologist
magazine concludes that the UK Government’s reliance on a report based on
allegedly flawed data has led it to mislead Parliament on the potential climate
change impacts of fracking.
This latest report, Whitehall’s ‘Fracking’ Science
Failure, calls into question the basis for the Government’s reliance on the
2013 Mackay-Stone report (which concluded that: “With the right safeguards in
place, the net effect on UK GHG emissions from shale gas production in the UK
will be relatively small”) by demonstrating that the data used in the
calculations was suspect, and that the Government should reasonably have been
expected to know this at the time.
The conclusions are based on the fact that the
MacKay-Stone report is in turn based on data from the now-discredited Allen et
al (2013) report – Measurements of Methane Emissions at Natural Gas Productions
Sites in the United States, which resulted in them using bottom-up data. Paul
Mobbs stated that this “traditionally under-estimated emissions by two to four
times” and using estimated figures “for gas production per well were at least
twice what is seen in US gas wells – and had no clear independent source”.
Mr Mobbs concludes that:
“Using a figure for leakage which was perhaps a half
of what it should have been, and using a figure for gas production which was
twice what it should have been, the level of impacts which their analysis found
is arguably a quarter of what it should be.”
If this the case, then the Government’s argument that
using shale gas has a lower climate change impact than coal is not valid.
The report concludes that: “the Mackay-Stone report
must be withdrawn, and a moratorium implemented on all ‘fracking’ operations,
until we can state the impacts with certainty.”…
