Fracking and climate change
Urgent: Take Action
The government are planning to make non-hydraulic exploratory drilling for shale gas Permitted Development, which means fracking companies won’t need local planning permission to build a 1.5-hectare exploratory well site. They are also planning to make full scale industrial fracking a Nationally Significant Infrastructure Project, which means the decisions regarding whether or not fracking is allowed will be made by the Secretary of State and a Planning Inspector – not your local council planning authority.

Legal action is being taken by Talk Fracking against the government's revised National Planning Policy Framework, and separately by a North Yorkshire mayor, Paul Andrews, against the Written Ministerial Statement underlying this.
The Committee on Climate Change has concluded that exploiting shale gas by fracking on a significant scale is not compatible with UK climate targets unless three tests are met. Read more about why we believe not only that the tests will not be met, but also that the government is not even taking them seriously. Fracking and climate factsheet.
A bridge to nowhere
Fracking (hydraulic fracturing) is a means of extracting natural gas from shale rock by pumping water in at high pressure. It has been responsible for serious local pollution, including poisoning drinking water supplies, in the US.
It has been argued that as a lower-carbon fuel than coal, shale gas can act as a 'bridge' to low-carbon power, allowing more time for renewable energy to become more efficient. However, the counter-argument is that developing fossil fuels makes it more difficult to switch from a high-carbon future to a low-carbon one.
The UK’s commitment to making our fair contribution to reduce emissions in line with keeping global warming below a 2°C rise gives a very clear global carbon budget – and hence a UK budget – i.e., how much carbon we can put into the atmosphere over this century. Here the maths is unambiguous – we have insufficient budget for the carbon we are already emitting. By the time shale gas is produced in any quantity (five to ten years) there will be no emissions space left for it.
In the absence of a stringent limit on total carbon emissions shale gas will not substitute for coal - certainly not on a global level.
Shale gas directly competes with investment in renewable technologies vital for combating climate change.
The US has seen an increase in the release of methane gas as a direct result of fracking. This is important because methane is a far more potent greenhouse gas than CO2. Substituting gas for coal only benefits the climate if leakage can be kept below 2%. Evidence on methane emissions from fracking in the US suggests it is significantly higher than this. The Scottish government has released a series of reports highlighting the damages, and risks, of fracking. The Scottish Parliament voted supporting an outright ban on fracking earlier this year.
Whitehall's Fracking Science Failure
A new report by Talk Fracking has come out detailing how Whitehall's push for fracking is based on reports and studies that have misled Parliament and understated the impact of fracking. Examples of flaws in those papers include:
- Usage of bottom-up "inventory studies", rather than the direct measurement of emissions in shale production areas produced by top-down studies. There is growing concern about the accuracy of inventory-based statistics since in-field sampling has demonstrated that using inventory-based data under-reports emissions. Figures from top-down studies were excluded from the report used by the DECC to support fracking, which results in an incomplete picture of the total emissions.
- Failed to account for more short-term impacts, using 100 year periods rather than 20 years, which leads to underestimates of the effects of greenhouse gases such as methane, which have a far more drastic effect on the rate of climate change in the immediate future.
- The Allen Study used to support claims for the Mackay-Stone report came immediately under criticism: authors did not disclose their connections to the fossil fuel industry, the surveyed sites were all volunteered and selected by the study's fossil fuel industry partners, and the overall sample size was 0.1% of wells in the USA. All this means that not only is the study unrepresentative of USA fracking, it most likely cannot be used as a reference for UK fracking as well.
The report shows how the policy decisions on fracking that have been made are based on misleading reports and statistics, which has led to the government continuing to push fracking. The report concludes with the recommendation that the government immediately reviews the policies on unconventional shale gas and oil, as well as the studies and reports used, such as the Mackay-Stone report and the Allen Study.
