ONE Future Commitment Option
National Grid is also a member of the ONE Future Coalition and made a Methane Challenge ONE Future commitment. As a member of this Methane Challenge commitment option, National Grid reports additional detailed data on methane emissions and voluntary methane reductions across its operations to Methane Challenge annually. This ONE Future commitment option dataset can be found in the Methane Challenge ONE Future Dataset at the bottom of this page.
ONE Future will use this ONE Future commitment option dataset to assess National Grid's progress towards its emissions intensity target. Please visit the the ONE Future Coalition's website for more information on the emission intensity targets and calculations.

| Target Year: | 2016 |
| Target Replacement Rate: | 1.5% |
| Current Replacement Rate: | 4.28% |
Graph shows: The blue bars show National Grid’s annual cast iron and unprotected steel mains replacement rate. The green star indicates its 2016 target annual replacement rate (1.5%). National Grid has implemented this commitment by replacing cast iron and unprotected steel mains with plastic mains, reconditioning cast iron mains with plastic pipe inserts, and replacing unprotected steel with protected steel.
Distribution
Services - Cast Iron and Unprotected Steel
| Year | Replacement Rate (%) |
|---|---|
| 2017 | 5.09746942729144 |
| 2018 | 1.99040749608961 |
| 2019 | 2.13 |

| Commitment Details | Company Selection |
|---|---|
| Segment: | Distribution |
| Target Year: | 2016 |
| Current Replacement Rate: | 1.55% |
Graph shows: The blue bars show National Grid’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. National Grid has implemented this commitment by replacing cast iron services with plastic and by replacing unprotected steel services with plastic and protected steel.
Methane Reductions
| Year | Methane Reductions (MTCO2eq) |
|---|---|
| 2017 | 54071.6739528 |
| 2018 | 49118.9235432 |
| 2019 | 49302.4 |

| 2021 | 44147.88 |
| 2022 | 35337.35797 |
Since joining the Methane Challenge program, National Grid 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: 9,701 metric tons
- Reductions in carbon dioxide equivalents: 271,621 metric tons
- Natural gas savings: $3,536,738*
*Natural gas savings assumes a natural gas price of $7.00 per thousand cubic feet, based on the average of daily Henry Hub Natural Gas Spot Prices in 2022, rounded to the nearest dollar

*ONE Future Commitment Option Data Review Process
For 2017 - 2021 data, EPA conducted a basic review of the data elements related to voluntary emissions reductions. In subsequent years, EPA plans to expand data review to include other data elements.
In future data reporting cycles, Partners may update and resubmit data that was previously submitted, as needed. Resubmitted data will be included in the next program data publication.
Methane Challenge Accomplishments Calculation Methods
This document describes how EPA analyzes Partner-submitted data to calculate Methane Challenge program ‘accomplishments’; specifically, the partner commitment progress metrics shown on each Partner Profile webpage as well as Methane Challenge program-level methane reductions.
Methane Challenge Accomplishments Calculation Methods (pdf)
This document does not describe how Methane Challenge Partners calculate the data they report to EPA. Those calculation methods are detailed in the Methane Challenge Technical Documents.
Pursuant to 5 CFR § 2635.702(c)(2), names are displayed here as the result of recognition for achievement given under an agency program of recognition for accomplishment in support of the agency’s mission. Any reference to a specific company or commercial product or service by trade name, trademark, manufacturer, company, or otherwise does not constitute or imply the endorsement or recommendation of EPA.
About 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 Program Fact Sheet (pdf) .
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).

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.
