The choice is yours. Add 1% to 100% RNG to your purchase profile. Here are a few examples of the potential impacts on your GHG footprint for a medium-sized home of about 160 m2 heated with natural gas.

How do you choose your percentage?
Use the Customer Space to estimate the impact of different RNG percentages on your personal consumption, with no obligation on your part.
Log in to the Customer space. If you don't have an account, choose the "Create my account" option.
On the home page, click the “Manage Option” button in the Renewable Natural Gas section. If you have multiple accounts, select the desired account first.
Then select the “Voluntary Purchase” option.
Move the cursor to determine the quantity of RNG and compare the effects on your monthly bill and your GHG emissions report.
To find out more about the GHG emissions of RNG and learn about the impact of your voluntary purchase of RNG on Quebec’s GHG emissions and your own GHG emissions, see our frequently asked questions.
Determine the percentage of renewable natural gas you wish to purchase and select the effective date. Then click the “Submit my request” button.

Get in on the Decarbonization Incentive Program (DIP)
By signing a binding 5-year agreement to purchase at least the amount required to meet the regulatory threshold (i.e., 5% of your gas consumption for Énergir’s 2025 fiscal year),you may be eligible for a grant.
Renewable natural gas on your bill
The supply rate for RNG is set annually as part of the Rate Case filed each year with the Régie de l'énergie. Please note that Énergir’s rate under the Cap-and-Trade System (SPEDE) is not billed for RNG.
You'll find the cost associated with your purchase percentage in the Calculation of the Amount Billed section of your invoice, as in this billing example.

You can request a change at any time to the amount of renewable natural gas you voluntarily purchase. As a customer, for an effective date of the first of the following month, you must submit your request no later than the 20th of the current month. Requests received after the 20th of the month will be processed with the following month’s requests. The change request is made directly in your Customer Space by specifying the revised purchase percentage and desired effective date.
There is no way to confirm the exact amount of purchased RNG that is delivered to your devices, since RNG and fossil natural gas flow through the same gas network and the molecules are thoroughly mixed together. The same is true for the electricity you purchase: you can’t tell which dam or wind turbine generated the electrons that are lighting your home.
The quantity that is voluntarily purchased by a customer differs from the quantity that is physically transported to the customer’s devices.
Énergir has put stringent measures in place to periodically ensure that its total annual supply from RNG producers to replace fossil natural gas is at least equal to the quantity purchased by all its customers and that the RNG it purchases is 100% organic (and does not include any fossil molecules). After the end of every year, Énergir has its RNG supply and inventory verified by the Bureau de normalisation du Québec (BNQ). The RNG volumes you purchase are shown on your detailed total natural gas consumption bills.
To meet the regulatory RNG targets, Énergir sources RNG primarily from producers located in the United States. It is working to increase its supply from producers in Quebec. The amount of RNG purchased by Énergir from each producer is injected by the producer into the gas distribution system in the region where the producer is located. It can be injected into the gas distribution system of Énergir or another distributor in North America and it is then blended with the fossil natural gas flowing through the same distribution system. For example, as is the case with Énergir’s supply of fossil natural gas or the supply of electricity, once the purchased energy is injected into the gas distribution system or the power system, the gas molecule or electron cannot be tracked. The gas molecule or electron is consumed by the different users connected to these systems.
The amount of RNG purchased by Énergir reduces the quantity of fossil natural gas that Énergir purchases as part of its overall supply. Since the RNG and fossil natural gas molecules flow through the same gas network and are mixed together indistinguishably, Énergir has a verification body conduct an annual verification to ensure that its total annual supply from RNG producers is at least equal to the quantity of RNG purchased by all its customers and that the RNG purchased is 100% organic (and does not include any fossil molecules).

RNG combustion is not emission-free; it generates GHG emissions (CO2, CH4 and N2O) just like the combustion of fossil natural gas. CO2 is the main GHG that is generated (over 99% of combustion emissions). For RNG, though, the CO2 emissions from its combustion are said to be biogenic because they come from biomass. Biogenic CO2 emissions are not generally targeted by climate change objectives, unlike emissions from the combustion of fossil natural gas. Although CO2 from the combustion of fossil natural gas can be reabsorbed by biomass during photosynthesis, burning fossil natural gas releases CO2 that has been sequestered for millions of years in geological formations and results in a net addition of CO2 to the atmosphere. In contrast, the CO2 released into the atmosphere from RNG combustion (biogenic CO2) was sequestered in organic matter (food waste, manure, wastewater, etc.), which renews much more rapidly, on a scale ranging from a few months to a few years. The biogenic CO2 was present in the atmosphere, was absorbed by organic residues and could be again re-emitted into the atmosphere. Biogenic CO2 is therefore part of the short carbon cycle. The actual effect of biogenic CO2 emissions from RNG combustion on the climate depends on a number of factors, including the biomass source and production processes. RNG sold by Énergir to its customers is produced from organic waste and has not led to significant changes in land use.
Énergir has a regulatory obligation to distribute a minimum amount of RNG during its fiscal year (2% in 2023-2024, 5% in 2025-2026 and 10% in 2030-2031). If customers do not voluntarily purchase a portion of that RNG, Énergir charges them for unsold volumes equal to at least the regulatory threshold, on their own gas consumption.
Thus, if demand from voluntary customers does not exceed the regulatory threshold regarding the quantity of RNG to be delivered, voluntary purchases will not impact the reduction of GHG emissions in Québec attributable to RNG. Conversely, if voluntary purchases exceed that regulatory threshold, they enable a further reduction of GHG emissions from RNG with respect to Québec.
It is a rate used to distribute the costs associated with the volume of RNG that is required for Énergir to meet its regulatory obligation but that was not voluntarily purchased by its customers. Énergir has a regulatory obligation to distribute a certain minimum quantity of RNG. Even when this entire quantity is not voluntarily purchased by its customers, Énergir is still bound by its obligation. In this case, in accordance with its Conditions of Service and Tariff, Énergir charges the cost of unsold volumes of RNG to customers who, relative to their own natural gas consumption, have not purchased at least the proportion of RNG that corresponds to the regulatory threshold (that is, 2% in 2023-2024, 5% in 2025-2026 and 10% in 2030-2031).
