Duke Energy Methane Challenge Partner Profile

Methane Challenge Partner Since 2016

Duke EnergyExit has committed to apply best management practices (BMPs) across its operations to mitigate methane emissions from the emission sources listed below.

Learn more about Duke Energy's progress towards meeting its commitments to implement methane-reducing technologies and practices related to these emission sources:

At the bottom of this page, you will also find the methane reductions that Duke Energy has achieved in the program.

Background Information: Information submitted by Duke Energy, including its full dataset, can be found on its document page. This page includes the following documents:

  • Methane Challenge Implementation Plan
  • Methane Challenge Reported Data


Services - Cast Iron and Unprotected Steel

Learn more about emissions from service lines, available options to mitigate emissions, and what the BMP Commitment for service lines entails.

Year Replacement Rate (%)
2017 76.4769065521
2018 7.89473684210526
2019 0
2020 0
Commitment Details Company Selection
Segment: Distribution
Target Year: 2020
Current Replacement Rate: 7.89%

Graph shows:  The blue bars show Duke Energy’s annual cast iron and unprotected steel services replacement rate. When committing to this source, partners commit to replace services when replacing the main; partners do not set a target replacement rate for services. Duke Energy has implemented this commitment by replacing unprotected steel services with plastic.


Excavation Damages

Segment: Distribution
Target Year: 2021
Target Reporting Rate: 100%
Current Reporting Rate: 100%

Graph shows:  The blue bars show Duke Energy’s annual progress towards reporting on all Excavation Damages data elements. The green star indicates its 2021 target annual rate (100%).

Methane Reductions

Year Methane Reductions (MTCO2eq)

Since joining the Methane Challenge program, Duke Energy 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: 47 metric tons
  • Reductions in carbon dioxide equivalents: 1,185 metric tons
  • Natural gas savings: $7,405*

*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.
