Since joining the Methane Challenge program, Dominion Energy Transmission, Inc. has achieved the following methane emissions reductions, which are also expressed in terms of carbon dioxide equivalents and the value of the amount of natural gas saved:

  • Methane emissions reductions: 16,218 metric tons
  • Reductions in carbon dioxide equivalents: 405,452 metric tons
  • Natural gas savings: $2,534,077*

*Natural gas savings assumes a natural gas price of $3.00 per thousand cubic feet, based on the average of daily Henry Hub Natural Gas Spot Prices in 2018, rounded to the nearest dollar

Methane Challenge Program LogoAbout the Methane Challenge Program

The Methane Challenge Program provides a new mechanism through which U.S. oil and gas companies can make more specific and transparent commitments to reducing methane emissions. Partner companies choose between two commitment options to cost-effectively reduce methane emissions. For background information on the Methane Challenge program, please check out the Methane Challenge Fact Sheet.

Best Management Practice (BMP) Commitment
The BMP Commitment is intended to spur near-term, widespread implementation of methane mitigation activities across the oil and natural gas value chain to address methane emissions from key emitting sources. By committing to address an emission source, the partner is committing to implement a BMP on all such sources in their operations. Progress towards a commitment is generally indicated by the percent of sources to which the partner has implemented a BMP as part of the Methane Challenge. Commitments for a few sources are instead based on achieving a target rate (of equipment replacement or methane emission reductions).
Learn more about the BMP Commitment.

ONE Future Emissions Intensity Commitment
The ONE Future Commitment is intended to drive action to achieve segment-specific intensity targets, established through the ONE Future Partnership, which will represent emissions per volume produced or volume of throughput and add up to a 1% or less “leakage rate” along the natural gas value chain by 2025.
