North Carolina natural gas customers can reduce their carbon footprint for as little as $3 per month. GreenTherm is a voluntary program that offsets carbon emissions from natural gas use in customer’s homes and businesses. The program supports renewable natural gas and methane reduction projects in North Carolina, and New York that reduce greenhouse gas emissions.

GreenTherm

GreenTherm is available to residential and commercial customers and will expand in the coming months. To participate, you may purchase carbon offsets in $3 blocks on your monthly bill. A typical residential customer can offset their entire natural gas carbon footprint each month by purchasing four $3 blocks a month, or $12 total a month, achieving net zero carbon emissions from their monthly natural gas usage.

Typical Customer Type Typical Annual Usage in therms Typical Monthly Usage in therms Est. Blocks to Achieve Carbon Neutrality Est. Monthly Cost Est. Annual Cost

Project type: Landfill gas capture/combustion
Name: Buncombe County Landfill
Location: Alexander, NC
Registry: Climate Action Reserve, Project ID: CAR531

When landfill waste decomposes, it produces greenhouse gas emissions. This project captures those emissions before they enter the atmosphere by installing a network throughout the landfill that gathers methane as it is emitted. After the methane is extracted, it is cleaned and used to generate renewable electricity.


Project Type: Landfill gas capture/combustion
Name: Gaston County Landfill
Location: Dallas, NC
Registry: Climate Action Reserve, Project ID: CAR475

When landfill waste decomposes, it produces greenhouse gas emissions. This project captures those emissions before they enter the atmosphere by installing a network throughout the landfill that gathers methane as it is emitted. This methane is then flared (burned). The emissions from burning the methane are much less potent than if the methane was allowed to escape into the atmosphere.


Project type: Landfill gas capture/combustion
Name: Upper Piedmont Landfill
Location: Rougemont, NC
Registry: Climate Action Reserve, Project ID: CAR620

When landfill waste decomposes, it produces greenhouse gas emissions. This project captures those emissions before they enter the atmosphere by installing a network throughout the landfill that gathers methane as it is emitted. This methane is then flared (burned). The emissions from burning the methane are much less potent than if the methane was allowed to escape into the atmosphere.


Project type: Landfill gas capture/combustion
Name: Johnston County Landfill
Location: Smithfield, North Carolina
Registry: Climate Action Reserve, Project ID: CAR880

When landfill waste decomposes, it produces greenhouse gas emissions. This project captures those emissions before they enter the atmosphere by installing a network throughout the landfill that gathers methane as it is emitted. After the methane is extracted, it is cleaned and used to generate renewable electricity.

Note: The projects supported by GreenTherm may change over time depending on the availability of carbon offsets.

GreenTherm is a carbon offset program that allows customers to voluntarily offset carbon emissions from natural gas use in their home or business by supporting projects reduce greenhouse gas emissions.

ThermWise is an energy conservation program that promotes the use of energy efficient practices and rebates to reduce natural gas usage.

Carbon offsets compensate for emissions from one source, such as your home, by reducing emissions from another source, such as a landfill. That way there is no overall increase in emissions. Carbon offsets are an effective tool used by people, businesses and governments around the world to combat climate change.
Most of our everyday activities, such as driving, using electricity or using natural gas, produce emissions. When we use natural gas to heat our home or cook food, we produce emissions as well. This program offsets emissions from your home by reducing emissions from other sources.
Everyone has a role to play in combatting climate change. Our company is taking bold and important steps every day to achieve our goal of net zero emissions. This program is an affordable way for our customers to join us on our journey and have a positive impact on the environment.
When a qualified carbon mitigation project is completed and reduces emissions from a source, the project developer can sell carbon offsets to a third party through a transparent and independently certified process. These carbon offsets must be independently measured and validated to ensure the emission reductions are real, accurate, permanent, and additional to what would be expected from normal day-to-day practices. We purchased the offsets for this program through a competitive bidding process to make sure they provide the best value for our customers. We then sell the offsets to our customers who participate in the program. We do not make a profit from the program.
Participation in the GreenTherm program is completely voluntary. A typical customer can elect to pay a surcharge of $12 per month, or four blocks per month, to completely offset their home’s emissions each month, or purchase more blocks to offset even more emissions. Participation can be cancelled once during a 12-month period.
No. We do not make a profit from the program.
No. Customers who do not participate will not pay more for natural gas.
