However, the researchers warn that more than half of the recent emissions reductions in the power sector may be displaced overseas by the trade in coal.
Dr John Broderick, lead author on the report from the Tyndall Centre for Climate Change Research, comments: "Research papers and newspaper column inches have focussed on the relative emissions from coal and gas.
"However, it is the total quantity of CO2 from the energy system that matters to the climate. Despite lower-carbon rhetoric, shale gas is still a carbon intensive energy source. We must seriously consider whether a so-called "golden age" would be little more than a gilded cage, locking us into a high-carbon future."
Professor Kevin Anderson of the Tyndall Centre notes: "Since 2008 when the shale gas supply became significant, there has been a large increase in US coal exports. This increases global emissions as the UK, Europe and Asia are burning the coal instead. Earlier Tyndall analysis suggests that the role for gas in a low carbon transition is extremely limited, with shale gas potentially diverting substantial funds away from genuinely low and zero carbon alternatives"
This Co-operative commissioned report "Has US Shale Gas Reduced CO2 Emissions?" is the third on shale gas from the Tyndall Centre – and builds on several years of research and submissions to the UK and European Parliaments as well as the International Energy Agency.
Chris Shearlock, Sustainable Development Manager at The Co-operative, said: "The proponents of shale gas have always claimed that it is a lower carbon alternative to coal. However, this is only true if the coal it displaces remains in the ground and isn't just burnt elsewhere. Without a cap on global carbon emissions, shale gas is burnt in addition to other fossil fuels, increasing total emissions."

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
