A low-carbon program for large-volume customers

To support large-volume customers in lowering costs and emissions, Enbridge Gas is working to expand access to cleaner energy solutions.

We’ve applied to the Ontario Energy Board (OEB) to offer a new voluntary program that will make it easier to substitute a portion of your natural gas supply with carbon-neutral renewable natural gas (RNG), which is not subject to the federal carbon charge.

Calculate the impact of RNG on your bill, and on the environment

If your annual consumption is 50,000 m3, and you elect to receive 25% of that amount as RNG, your incremental cost, including the reduction in your federal carbon charge, would be $5,611.25. Plus, you would be reducing your greenhouse gas (GHG) emissions by 24 tC02. That’s like taking five gas-powered vehicles off the road each year! Our calculator can help you identify the impact RNG can have on your bill, and on the environment.

What is RNG?

Created by capturing methane emissions from organic waste, landfills and wastewater treatment plants, RNG provides a carbon-neutral energy source that also helps manage waste, reduce greenhouse gas (GHG) emissions and fight climate change.

Carbon neutral

Diverts methane—one of the most harmful GHGs—that would otherwise be released into the atmosphere.

Diverts waste from landfill

As Ontario’s landfill capacity is expected to run out by 2032*, RNG offers an immediate solution.

Versatile, resilient and market-ready

A made-in-Ontario solution that’s more resilient and easier to adopt than other types of low-carbon energy sources.

How you’ll benefit

thumbs up

Flexible and convenient
RNG requires no upgrades or changes to your existing infrastructure—it’s a customizable solution and a one-for-one replacement for conventional natural gas.


An easy way to reduce emissions
Replacing conventional natural gas with carbon-neutral RNG means lower GHG emissions, helping you meet your corporate sustainability goals.

Stacked coins decrease

Lower federal carbon charges
By using RNG to lower GHG emissions, you can reduce your federal carbon charge.

How it works

If the program is approved by the OEB, large-volume Enbridge Gas customers will have the opportunity to choose a percentage of their annual natural gas supply provided as RNG. Prices vary based on how it’s produced and used.

RNG is not subject to the federal carbon charge. Reducing your federal carbon charge will help offset the price difference between RNG and conventional natural gas.
