It is because it forms a double bonding between the cole-atom, and the oxygen-atoms that looks like this: O=C=O . This way, the electron negativity that Oxygen has does not affect the structure of the molecule because it is equally spread out on both sides.

As a side-note, water, H2O, which is a polar molecule, has the structure of an upside-down turned V, with Oxygen at the tip, and hydrogen at the bases of the two legs. This structure decends from the fact that the oxygen is slightly polarized, and that it "drags" the two, slightly positively charged, hydrogen atoms, forming a triangle with ~105o between the two O-H bonds.

Carbon dioxide (CO2) is not polar because it is linear and symmetrical. The structure would look something like this O=C=O so the O on each side cancel each other as far as polarity goes, thus making CO2 non polar.

Carbon dioxide is non polar because of its molecular geometry, which is linear (opposite ends of the molecule are not oppositely charged)
