Hybridisation of any atom in a molecule corresponds to the number or σ bonds it is making covalently with other atoms.

In CO₂, carbon is attached to two oxygen atoms through double bonds. Out of which two are σ bonds and the rest two are π bonds forming I−p π bonding between carbon and oxygen.

The two σ bonds correspond to the hybridization sp and give a linear shape to CO_2.
