phase out

Wind down slowly

To phase out is to discontinue something gradually rather than all at once: The company is phasing out its older product lines.

A phase-out allows for transition—replacing equipment, retraining workers, or letting contracts expire naturally.

Coal plants are being phased out in favor of renewable energy.

The noun is phase-out or phaseout.
