LONDON, Dec. 10, 2015 /PRNewswire=KYODO JBN/ --

As ministers from around the world gather at COP21 in Paris in a bid to come to

an agreement on a new global climate compact, an environmental scientist from

Xi'an Jiaotong-Liverpool University has warned that the controversial method of

fracking, which is being investigated by many countries as an alternative fuel

source, is inconsistent with climate change mitigation policies.

Dr Philip Staddon, from the Department of Environmental Science at XJTLU, warns

that fracking contributes both directly and indirectly to greenhouse gas

emissions and, despite being "dubiously" portrayed as environmentally friendly,

delays the transition to a low carbon future.

Hydraulic fracturing for shale gas, or fracking, is the process of drilling

down into the earth before a high-pressure water mixture is directed at the

rock to release the gas inside. The desire for short-term (next 30 years)

energy security has re-invigorated investment in fossil fuel technologies and

led to a North American boom in fracking, as well as protests by environmental

campiagners against the technique.

In an academic opinion piece for Environmental Science & Technology,

co-authored with Professor Michael Depledge from the European Centre for

Environment and Human Health, Dr Staddon states that addressing climate change

and meeting the world's energy needs are two of the greatest challenges that

societies face, and that the search for inexpensive and plentiful energy

supplies appears to be at odds with climate change mitigation commitments.

Evidence suggests that recent climate change arises primarily from human

activities that release greenhouse gas emissions, including carbon dioxide, and

methane, into the atmosphere.

"Lowering greenhouse emissions requires reduced dependence on fossil fuels,

rendering...the search for new sources of oil and gas particularly perverse,"

writes Dr Staddon in the piece.

"Expanding fossil fuel extraction capabilities sends the message that rapid

climate change mitigation is neither urgent nor essential."

The opinion piece highlights that the carbon footprint of shale gas carbon is

very similar to that of coal when compared over 100 years and that evidence

contradicts the view that shale gas is a "clean" or "environmentally friendly"

energy source.

"The dangers posed by "greenwashing" shale gas as a route to climate change

mitigation, are well documented. It is unimaginable that oil and coal reserves

will be left in the ground, therefore shale gas represents an additional source

of greenhouse gas emissions," writes Dr Staddon.

Dr Staddon, whose research looks at the response of ecosystems to environmental

change, especially climate change, added: "Government ministers are meeting at

COP21 to discuss worldwide limits to greenhouse emissions, yet fracking for

shale gas will extend the fossil fuel age, increase the costs of mitigation and

drive up the cost of adaptation required to support human societies in a less

hospitable climate. The negative financial impacts on economies and to human

health will be externalised and borne by those often poorer societies most

affected by climate change."
