The business case for sustainability is clear and organizations are responding to the imperative to act. But with 50-70% of the change needed involving the supply base, procurement and supply chain functions are critical to success. Sustainable Procurement explains how procurement and supply chain professionals can develop existing best practice approaches to make supply side sustainability a reality. Based around the OMEIA® Sustainable Procurement process, this book provides a step-by-step and highly practical methodology that embeds sustainable procurement into existing proven procurement approaches. It also provides crucial new tools that equip and enable those in this field to drive highly effective supply-side sustainability. By exploring the current landscape and the business case for sustainability, Sustainable Procurement makes sense of how we can translate good ambition into prioritised grass roots level change. Guidance is offered on how procurement can help redefine what an organisation does based upon what needs to change in its supply base. There are extensive resources to help determine hot spot risk areas, assess suppliers, and determine and prioritise where to direct our precious resources. It also provides new models for 'sustainable value engineering' to help organisations transform what and how they buy. Written by leading procurement expert and best-selling author, Jonathan O'Brien, this practical guide outlines how to establish sustainable procurement as a key strategic enabler to reduce supply-side risk and drive action to respond to detrimental impacts in the supply base.
