Methane leaks from natural gas systems follow extreme distributions

Natural gas production site equipment with methane leak shot with a FLIR camera.

Even relatively small leaks from the natural gas system can create large climate concerns because natural gas is comprised mostly of methane (CH 4 ), a gas with high global warming potential (GWP, ~34 times that of CO 2 over 100 years, ~86 times on a 20-year basis). Using a very big sample, this study …

Upward revision of global fossil fuel methane emissions based on isotope database

Graph showing the revised and much higher than previously assumed amounts of methane emissions to the atmosphere.

By revising the isotope source signatures this study finds that total fossil fuel methane emissions (fossil fuel industry plus natural geological seepage) are 60 to 110 per cent greater than current estimates suggest. Abstract Methane has the second-largest global radiative forcing impact of anthropogenic greenhouse gases after carbon dioxide, but our understanding of the global …

The compatibility of UK onshore petroleum with meeting the UK’s carbon budgets

OS-cover-snip-250x350

The Committee’s report ‘The compatibility of UK onshore petroleum with meeting the UK’s carbon budgets’ is the result of a new duty under the Infrastructure Act 2015. This duty requires the CCC to advise the Secretary of State for Energy and Climate Change about the implications of exploitation of onshore petroleum, including shale gas, for …

Shale Gas Production in England – an updated public health assessment

medact_shale-gas_COVER-636x900

Medact released in July 2016 an updated assessment of the potential health impacts of shale fracking in England.  This new report reaches broadly the same conclusions as our 2015 report Health and Fracking, however it is now supported by a much larger body of evidence published in the year since the first report was produced.  In the …

Fuelling the Fire: Underground Coal Gasification and Coal Chemicals

This figure shows the basic outline of the underground coal gasification process

Fuelling the Fire: the chequered history of Underground Coal Gasification and Coal Chemicals around the world was launched today by Friends of the Earth Scotland and Friends of the Earth International. It is a global report with case studies from Australia, South Africa, the US, China and the UK and details the history and environmental …

Air monitoring of VOCs during hydraulic fracturing operations in Washington County, Pennsylvania

Flaring can be one major source of unhealthy volatile organic compounds.

According to the authors, the primary finding of this study was that the operation of a hydraulic fracturing well pad in Washington County did not substantially affect local air concentrations of total and individual volatile organic compounds. Key findings: The results of the continuous monitoring during fracturing and flaring sampling periods for total volatile organic …

Characterizing Air Emissions from Natural Gas Drilling and Well Completion Operations in Garfield County, Colorado

This public and industry sponsored field study by Jeff Collett and colleagues, Colorado State University (CSU), is the first in class to quantify emissions of chemical compounds (air toxics, ozone precursors, and methane) during new well development and to characterize how these compounds are dispersed in the atmosphere downwind of the site. The study was …
