Cautious green light for fracking

The government’s climate change advisors have given a cautious green light to fracking in the UK.

The Committee on Climate Change (CCC) says fracking can go ahead if three key tests are met.

And the government says it already plans to meet those tests – on methane leaks, gas consumption and carbon budgets.

Environmentalists argue fracking will make the UK’s climate change targets impossible to achieve.

But the CCC disagrees. Its tests of government policy are:

  • Emissions should be strictly limited during shale gas development, production and well decommissioning. The CCC says this needs tight regulation, close monitoring of emissions, and rapid action to address any leaks.
  • Overall gas consumption in the UK must remain in line with UK carbon budgets – so UK shale gas must displace imported gas, rather than increasing gas consumption overall.
  • Emissions from shale gas production must be counted as part of the UK’s carbon budgets, and emissions in another part of the economy may need to be cut further in order to accommodate fracking.

Though the government is confident these conditions will be reached, a spokesperson admitted that any increase in current carbon emissions in future would make current targets even more challenging.

There is already a growing mismatch between the government’s long-term promises on climate change and the policies to deliver carbon cuts according to the CCC and National Grid.

There is huge uncertainty about the projections on fracking from the CCC and the government.

The UK currently has no shale gas production, and many observers believe the potential of fracking in the UK has been hyped.

Learning lessons

A CCC scenario projecting the most aggressive trajectory of shale gas development with minimum necessary regulation by 2030 estimates emissions of around 11 million tonnes of CO2 a year.

But even that is only a quarter of the UK’s emissions from agriculture and land use change. One expert told BBC News: ‘This is more or less loose change when it comes to the carbon budgets. It’s likely that the local effects like lorry disturbance will prove a more significant issue.’

The CCC mostly accepts the government’s reassurances on its three tests. The government is confident it has learned from regulatory failures in the early days of so-called wildcat fracking in the US.

Jim Skea from the committee says with best practice, UK shale gas may have a lower carbon footprint than much of the gas currently imported, which has to be compressed at great energy cost.

But he wants more detail on rules over the completion of wells, when methane can burp out along with the fracking fluid injected into the ground to release the gas. He also wants chapter and verse on how wells will be inspected after they have been decommissioned and before they are abandoned.

‘The CCC accepts that the government plans are mostly on track but wants more detail. Our recommendation is to monitor what government does because we are making the assumption that we have a very well regulated industry and we need some details filled in on that.’

The CCC also urged the government to make progress on capture and storage technology, which allows fossil fuels to be burned with minimal emissions of CO2.

The prime minister previously said this was vital for the UK before he scrapped a competition to develop it – in order to save cash.

The previous head of the Environment Agency, Chris Smith, said fracking should only go ahead if CCS was imposed, and the CCC report says that without CCS the UK would need to eliminate almost all CO2 from all sectors of the economy by 2050.

A government spokesperson said ministers were working on other ways of encouraging CCS without a publicly-funded competition. He also confirmed that the government still intended to show by the end of the year how it would achieve long-term CO2 targets.

Richard Davies from Newcastle University, said: ‘To do what the Committee on Climate Change recommend, and do it transparently, could force the UK to develop the world’s best “smart” monitoring technologies for emissions from well sites. There will be new business opportunities if a shale industry takes off.’
