The invention relates to a leather, and discloses a production method for an environmentally-friendly leather. The method comprises the following steps: placing polyvinyl chloride into a mold, and performing injection molding foaming to obtain a core layer of the leather; uniformly spraying a leather anti-mould agent on the upper and lower surfaces of the core layer, wherein the temperature of thecore layer is controlled at 55-60 DEG C in the spraying process; after the anti-mould agent is sprayed, allowing the core layer to stand for 0.5h, and then uniformly spraying a desiccant; and 1h after the desiccant is sprayed, performing hot pressing on the upper and lower surfaces of the core layer by a non-woven fabric layer, wherein the temperature of hot pressing is 100-120 DEG C. According to the method provided by the invention, the leather anti-mould agent is sprayed into the leather at a certain temperature in the production process of the leather, so that the interior of the leatherfully absorbs the anti-mou
