Sustainability does not have a universal and established definition. In fact, producing clothes or footwear will never be 100% sustainable because it will always require the use of water and energy along with other resources and will inevitably generate some waste.  The baseline to set up this standard was to define the threshold under which a production process causes irrevocable damage to the environment, the workers, or the consumers’ health. Certified products must meet this threshold in all areas covered by the standard because it would be inSANE only to protect the planet while exploiting people or vice versa.
