Quantifying the Invisible: Getting a Handle on Methane’s Climate Impact

Robin Beckwith, Staff Writer JPT/JPT Online

Earlier this year, a Cornell University professor made quite a splash publishing a paper asserting that emissions from shale gas rivaled those from coal. A July 2011 study issued by the Post Carbon Institute underscored this conclusion. Not so, say five separate recent reports–from Carnegie Mellon University, IHS Cambridge Energy Research Associates (CERA), the US National Energy Technology Laboratory (NETL), Argonne Laboratory, and Deutsche Bank Climate Change Advisors (coauthored by individuals from Worldwatch Institute and ICF International). At heart are issues related to measuring and quantifying emissions of an odorless, colorless gas–methane (CH4)–considered the second-most prevalent long-lived greenhouse gas after carbon dioxide (CO2).
