Scientific American: Switching from coal to natural gas may be better for the climate than previously thought: new measurements see lower fugitive emissions from fracking

A new study finds that methane emissions from shale gas production are nearly 50 times lower than previous estimates, improving the climate benefit of switching from coal to natural gas.


The Hill: Study finds limited greenhouse gas emissions from fracking

The oil-and-gas industry saw the new numbers as an indication that additional fracking regulations are not necessary.

Hydraulic fracturing involves high-pressure injections of water, chemicals and sand into rock formations to release trapped gas.

Natural gas produces far less carbon than coal does when burned to produce electricity. However, advocates and opponents of the energy resource have sparred over how much methane, a far more potent greenhouse gas, is leaked as a result of natural gas development. Some researchers have asserted that methane pollution caused by fracking makes the processas destructive to the climate as coal. Environmentalists who have opposed hydraulic fracturing asserted on Monday that the industry-backed analysis was deeply flawed.


EcoWatch: 100 Leading

Moving ahead rapidly with plans to approve several new liquefied natural gas (LNG) terminals would require "a rapid increase in fracking in the United States without credible science" and "could potentially cause undue harm to many Americans," according to 107 experts who signed on to a petition sent last week to the White House.

Video: The Science of Shale Gas & Oil (Lecture) 10.26.2015

Most recent invited public presentation by Dr. Tony Ingraffea, delivered October 26, 2015 at Mercyhurst University in Erie, PA.

In this video, Dr. Ingraffea first responds to community concerns about possible nearby development of the Utica shale. He then gives an update on the latest peer-reviewed science on fugitive methane emissions from leaking gas wells and shale gas & oil operations, their impact on climate change. He also discusses the relevance and effectiveness of current national energy policy in light of these emissions. (1 hour 45 mins)
