Morphology
The meaning 'a gas that traps heat' is directly derivable from combining 'greenhouse' (a structure that traps heat) with 'gas' (a gaseous substance); the compound denotes a gas that behaves like a greenhouse by trapping heat. This compositional metaphor is common in scientific discourse and across languages, so a B1 learner who knows both constituents would very likely infer the intended meaning.
Etymology
Greenhouse gas comes from the image of a glass greenhouse: sunlight gets in, but the glass keeps the warm air inside. A gas like carbon dioxide does the same thing in the sky by 'trapping heat', so the name means these gases help to 'warm the planet'.
