US natural gas producers hope climate-conscious electric utilities and gas exporters will pay a premium for what they say is "greener gas" that has been certified as coming from low-emission operations or from renewable sources such as landfills.
EQT Corp, Chesapeake Energy and liquefied natural gas firms Cheniere Energy and NextDecade Corp are among the companies considering low-carbon certifications from groups such as Denver-based Project Canary.
Gas certified as "responsibly produced" and contributing less emissions could get up to 5 per cent above market prices, or up to 15-cents per thousand cubic feet (mcf), proponents say.
So far, not many customers have been willing to pay the premium -- a problem for firms trying to sell lower-carbon versions of fossil fuels.
