Look up in the Chart of Specific Heats of Gases, there's an appended, subordinate chart called the Chart of Gas (energy-per-mole) Constants.
Addition of CO2 to atmospheric Air, causes it to hold less energy per mole, not more.

This is THE main chart of energy per mole in the Physical Sciences' gas laws; it's appended to what's today oft-referred to as ''the main gas law''
because of this chart's attachment to it,
as a subordinate PART of it. The equation for the law can be re-written to derive like five total gas laws, but the Ideal Gas Law
is the law scientific organizations decided to attach the charts to.
See line 3 on ''Individual Gas Constants.'' That's standard class Air.
See line 12? That's CO2.
Note that total energy-per mole (average) is lower than that for Air.
If you have standard Air mix, that you know the ratios of and it fits the calibration/sensing industries' standard for Earth Air mix at mean sea level, etc
and you open a port on one side of the top of the container,
so pressure can escape, (so Air can escape as CO2's trickled in)
and through another port you slowly enrich it with CO2, when it's all over with and your typical 99.9% of that volume's now filled with CO2 cause you let the heavier CO2 gently sink to the bottom and push the Atmospheric Air out of that open hole you placed in the top,
that volume of space filled now with CO2, retains LESS energy per mole,
than when you first started and it was all, Atmospheric air.
That's just a fact, fren. The individual gas (energy) constants on lines 3 and 12,
are what you plug into the math equations when you're sorting out your
mass/energy ratios for volumes of gases.
What the temperature's gonna wind up being, what the pressure's gonna wind up being, what volume it'll fill.
Stefan-Boltzmann, also isn't one of the gas laws.
It's defined as being a single-mode law, meaning there can be no conduction, there can be hence no convection either, since both are created by presence of gases. ''Single-mode heating/cooling'' means,
energy coming in is completely radiated in, energy coming out is completely radiated back out.
There's no help from the other two modes of cooling, conduction and convection. These two modes of cooling can't exist without a gas envelope, an atmosphere.
Hence the oft-seen phrase ''Stefan-Boltzmann is known as a single-mode law.''
Indeed there's an entire Chart of some values called ''The Stefan-Boltzmann Temperatures of Planets'' and it also includes a few planets' larger, rocky moons.
The Stefan-Boltzmann temperatures of the planets/moons involved, having any significant atmosphere,
are not, because - they can't be,
the same as the actual, official, measured temperature for that body.
Specifically because
the presence of an atmosphere is required to create multi-mode cooling.
Gas law also has processes to account for hydrostatics.
Hydrostatics is quantifying the changes that happen to the values of the other two,
between
volume, pressure, & temperature - when one of them changes.
The hydrostatic equation, the values that lead up to it - these functions can't exist if there's no atmosphere, and single-mode heating/cooling
is the energy gain/loss mode: because ( to state the obvious, ) if there's no atmosphere, there can't be a temperature
for a gas volume that doesn't exist,
and there can't be a pressure or volume either for a gas atmosphere that doesn't exist.
This is why for all the planets with significant enough atmosphere to calculate for, the official temperature,
will never be the Stefan-Boltzmann temperature for that planet.
