What Is Georgia Natural Gas Greener Life? Cost, Offsets and Our Take

GNG’s pages read October 20, 2026. Costs use the offer as checked October 18, 2026 and the PSC’s October 2026 chart. GNG’s current Greener Life promotion runs October 5 to November 4, 2026; we will update this post when it changes.

Greener Life is an optional add-on from Georgia Natural Gas (GNG) that buys and retires carbon offsets to match the carbon dioxide from burning the gas you use at home. It costs $4.99 a month for residential customers. Through November 4, 2026, new enrollees get it free for 12 months plus a 5¢-per-therm reward on 12 bills, which is how GNG advertises a 44.9¢ rate with code SIMPLE. For a typical Georgia household using 641 therms a year, that promotion is worth about $32.05 in the first year. After 12 months the $4.99 charge starts and the reward stops, so it is a good deal for a year and an ordinary paid offset program after that.

What Greener Life is

GNG describes Greener Life as “an optional service” for “a small monthly fee”: it calculates the greenhouse gases your gas usage releases and “will purchase and retire carbon offsets to balance the impact of those emissions” (GNG). It launched in October 2019 (GNG/Southern Company press release).

A few things it is not:

What it costs

A flat fee is the same whether you use 300 therms a year or 1,000, so the cost per ton offset is lower for heavier users. At 641 therms and the factor GNG uses (0.0053 metric tons of CO2 per therm, from the EPA), a typical household’s gas produces about 3.4 metric tons a year, so $59.88 works out to roughly $17.63 a ton.

How the SIMPLE promo math works

On its SIMPLE promo page, GNG shows two 12-month fixed cards side by side: 49.9¢ a therm, and 44.9¢ “12 Month Fixed + Greener Life.” The fine print explains the difference. The 44.9¢ is the 49.9¢ plan less a “$.05/therm line-item reward” for “a total of 12 consecutive bills, provided the customer remains enrolled in the Greener Life program,” and GNG credits the $4.99 Greener Life charge “for a maximum of 12 consecutive months.” Both apply only to residential customers who enroll between October 5 and November 4, 2026, and the reward is “available only one time per customer.” Flat-bill (Guaranteed Bill) customers get $2.50 a month instead of 5¢ a therm.

Here is what that means over a year for our standard household (641 therms, a $7.99 monthly GNG service charge, and $580.53 a year in Atlanta Gas Light base charges; see why we use 641 therms):

Option Rate Estimated cost, first 12 months
GNG 12-month fixed, code SIMPLE, with Greener Life 44.9¢ effective $964.22
GNG 12-month fixed, code SIMPLE, without Greener Life 49.9¢ $996.27
Lowest standard 12-month fixed plan on the PSC’s October 2026 chart (Fuel Georgia) filed $1,069.18

Because the 44.9¢ price depends on staying in an add-on and changes after 12 bills, the advertised offers table on the Georgia page lists it as a conditional offer, after the plain ones, with both the first-year and after-promo costs. That is our rule for every marketer, explained on the methodology page. Advertised offers are also listed separately from the standard filed fixed plans; see advertised vs filed rates for why.

Are the offsets legit?

Partly. The program is real and certified. The offsets behind it are a mixed bag.

What is solid:

What gives us pause:

Our take

Take it if you are signing up for GNG’s 12-month fixed plan with code SIMPLE by November 4, 2026 anyway. Greener Life is free for 12 months, the reward cuts about $32.05 off a typical first year, there is no contract, and a certified offset program is attached while you are in it. Put a reminder on your calendar for bill 11 or 12.

Skip it, or cancel at month 12, if your reason for joining is the price. Once the reward ends, it is $59.88 a year plus tax with no effect on your rate, and after about 6.4 paid months the first-year saving is gone.

Think twice if your reason is climate impact. $4.99 a month is not much and the program is certified, but most of what it buys is a credit type whose benefit is disputed, and it does not touch methane leaks. Using less gas (a programmable thermostat, a water-heater blanket, sealing ducts) cuts emissions you can be sure of.

And compare the whole offer, not the add-on. The SIMPLE + Greener Life first-year cost ($964.22) is close to the cheapest plain advertised offers on the Georgia page, which don’t require an add-on, and every one of these promotions expires. Check the advertised offers table and the standard fixed plans before you call, and see GNG’s page for its filed plans and PSC complaint counts.

Open Natural Gas is not paid by any marketer and no marketer can pay for placement.

How to cancel or remove Greener Life

Common questions

What is Georgia Natural Gas Greener Life?
An optional GNG add-on that buys and retires certified carbon offsets equal to the carbon dioxide from burning the natural gas you use. It costs $4.99 a month for homes after any free period, appears as a separate line on your bill, and can be cancelled at any time.
How much does GNG Greener Life cost?
$4.99 a month for residential customers ($59.88 a year), plus applicable taxes, and $9.99 a month for small commercial customers using 2,000 therms a year or less (GNG's published prices, checked October 20, 2026). Customers who enroll between October 5 and November 4, 2026 get a $4.99 credit for 12 months, so the first year is free.
Why is GNG's 44.9¢ rate tied to Greener Life?
The 44.9¢ price is GNG's 49.9¢ 12-month fixed price (code SIMPLE) less a 5¢-per-therm reward paid on 12 bills while you stay in Greener Life. At 641 therms a year it saves about $32.05 in the first year compared with the same plan without Greener Life (figures as of October 18, 2026).
Is Greener Life worth it?
For the first 12 months under the current promotion, yes, if you are choosing GNG's 12-month fixed plan anyway: it is free and the reward lowers your bill. After that it costs $59.88 a year and wipes out the first-year saving in about 6.4 months, so decide again at month 12.
Are Greener Life's carbon offsets real?
The program is Green-e Climate certified and uses projects registered with the American Carbon Registry and Climate Action Reserve. But 85% of the current mix comes from refrigerant reclamation, a credit type whose climate benefit independent researchers question, and the offsets cover only the burning of gas, not upstream methane leaks.
Does Greener Life change the gas delivered to my home?
No. The gas and the delivery by Atlanta Gas Light are the same. Greener Life is a charge for offsets. GNG also says it adds MiQ-certified low-emissions gas at no extra cost, but it does not say how much of its supply that is.
How do I cancel Greener Life?
Call GNG at 770-850-6200 or 1-877-850-6200 and ask to remove the Greener Life Signature Service. There is no contract or fee to cancel, but if you cancel during a promotion the 5¢-per-therm reward stops.
