Successful project execution and business operations depend on the performance of a strong supply chain. Weak links in a supply chain may be caused by a range of drivers beyond the safety, financial, quality and schedule indicators that have historically been considered in supplier selection and management. Sustainability aspects including environmental, social and governance issues can weaken supplier performance by causing lost production, supply interruptions, schedule delays, material inefficiencies, price increases, safety impairment, regulatory violations, employee issues and community resentment. This paper describes elements of ConocoPhillips’ Supply Chain Sustainability program as expanded in 2013 to support the improvement of our project execution and operations management through strengthening our supply chain on sustainability drivers that impact our business. A summary of the benefits of collaboration on sustainability issues to both oil and gas companies and suppliers is presented.
