1. Refinish or reface the cabinets you already have.

This is the greenest kitchen cabinet option by far because it minimizes new materials needed—which also means fewer volatile organic compounds (VOCs) that can off-gas and cause you health problems. And a refurb is a fraction of the cost of new cabinets. New cabinets could run $4,000-$20,000+; refacing might be half that.

If your cabinets are structurally sound but you just want a new look, add a coat of low-VOC paint or a new set of doors and hardware—it’s easy, inexpensive, and earth-friendly.
