It didn't directly.
But by keeping Britain out of the war, it ensured a Union victory. And that victory was what freed the slaves.

The Emancipation Proclamation freed the slaves in the Southern states, who already broke off from the union. This meant that President Lincoln had no control over whethere these slaves would be free or not. But once a Southern town or area was freed by Union soldiers, the slaves would be free. This caused help for the Union army from former slaves. The Emancipation Proclamation went into effect January 1, 1863.
Britain would have felt free to help the Confederates, with France likely to follow suit.
