The Complicated World of Methane

July 21, 2014 by David Hone

As governments struggle to find practical routes forward with positive outcomes for CO2 mitigation, attention is turning to dealing with other greenhouse gases, particularly methane. A number of methane emission initiatives are now underway or being planned.[read more]

Four Of 10 Fracked Wells In Pennsylvania Are Projected To Fail

Pennsylvania Fracking Well Risk

A major new study finds that, as suspected, it is new, unconventional gas wells that are far more likely to leak heat-trapping — and tap-water igniting — methane than older, conventional wells. Study after study has found consistently higher methane leakage rates from natural gas production and distribution.[read more]

Texas 'Fracking Contamination' Report Is an Embarrassing Media Blunder

June 12, 2014 by Steve Everley
1

A news report from WFAA in Dallas-Fort Worth alleges that recent tests “prove” fracking is to blame for methane in a resident’s drinking water aquifer. But the report does nothing to contradict the information showing that shale gas development is unrelated to the methane found in the groundwater.[read more]

Revisiting a Questionable Study on Shale Gas and Methane Leaks

May 9, 2014 by Steve Everley

For those who pay attention to the question over “methane leakage” from shale development, it was hard to ignore headlines describing research published in the Proceedings of the National Academy of Sciences, which looked at emissions data from a series of flyovers in southwest Pennsylvania.[read more]

How to Count Methane Emissions

Methane Emissions Measurements

In formulating policies to address greenhouse gas emissions, or evaluating the potential impact of different energy technologies on global climate change, one of the thorniest issues is how to account for the very distinctive characteristics of various different gases.[read more]

EPA Gets Started on Curbing Heat-Trapping Methane from Oil and Gas Operations

April 17, 2014 by David Doniger

The EPA recently took the first step promised under President Obama’s Strategy to Reduce Methane Emissions, released last month. The EPA issued a set of white papers examining five big sources of heat-trapping methane and other dangerous air pollutants from the oil and gas sector.[read more]

Catalyzing the Oil and Gas Industry to Clean Up its Act

April 7, 2014 by NRDC Switchboard

The oil and gas industry leaks a significant amount of natural gas into the atmosphere. Most of this leaked gas is methane, a powerful greenhouse gas pollutant. This leaked gas also represents a great deal of lost product for the oil and gas industry[read more]

Methane Leakage from Cows Higher than from Natural Gas Development

Methane Emissions

Since the onset of the shale gas revolution, many have worried that emissions of fugitive methane — the main component of natural gas and a greenhouse gas more potent than carbon dioxide on a molecule-for-molecule basis — are eroding the climate benefits of switching from coal to natural gas.[read more]

Opportunity: Plugging US Oil and Natural Gas System Methane Leaks

March 6, 2014 by Jared Anderson

Methane Leak Opportunity

A new methane emission study released recently details sources and potential costs associated with reducing emissions of the potent greenhouse gas from US energy infrastructure. The study found the US oil and gas industry could significantly reduce methane emissions using existing technology[read more]

Much Ado About Methane? A Little Global Context Helps Separate the Long from the Short

Methane Impact

Last Friday a paper was released that again showed that methane leaks in North America may be greater than previously estimated. The result was another round of debate as to whether natural gas is a suitable ‘bridge fuel’ to a sustainable future.[read more]

Methane Emissions Far Worse Than US Estimates, But Study Concludes Natural Gas Still Better Than Coal

February 18, 2014 by Marianne Lavelle

Methane Leaks and the Environment

Emissions of the potent heat-trapping gas, methane, the main component of natural gas, are likely 50 percent higher than U.S. government has estimated in its official greenhouse gas inventory, says a new study that is the most comprehensive effort yet to assess the problem.[read more]

Quantifying the Impact of Multiple Avenues of Methane's Underestimation

January 23, 2014 by Sieren Ernst

Cornell professors Robert Howarth, Renee Santoro, and Anthony Ingraffea ignited a controversy in 2011 when they published a study claiming that, due to escaped methane, emissions from hydraulically fractured natural gas were worse than coal.[read more]

Three Key Facts About the New Methane Paper

November 28, 2013 by Steve Everley

A new study published by the Proceedings of the National Academy of Sciences suggests that EPA’s greenhouse gas inventory may be underestimating total methane emissions in the United States, possibly by as much as 50 percent.[read more]

Bridge Out: Study Finds Methane Emissions From Natural Gas Production Higher Than EPA Estimates

November 28, 2013 by Joseph Romm

Methane Emissions

Natural gas is mostly methane (CH4), a potent heat-trapping gas. If, as now seems likely, natural gas production systems leak 2.7% (or more), then gas-fired power loses its near-term advantage over coal and becomes more of a gangplank than a bridge.[read more]

More Bad News For Fracking: IPCC Warns Methane Traps More Heat

October 7, 2013 by Joseph Romm

Methane and Heat Trapping

The IPCC reports that methane is far more potent a greenhouse gas than we had previously realized. This matters to the fracking debate because methane leaks throughout the lifecycle of unconventional gas. Natural gas is, after all, mostly methane.[read more]
