Strategic guidelines for sustainable procurement of infrastructure capital projects in the oil and gas industry

. Sustainable development and carbon dioxide emissions have been debated in the oil and gas sector as a basis for developing plans to reduce the emission of this gas in its operations, influenced by the commitments made in the Paris Agreement by reducing the emission of greenhouse gases (GHG). Investment funds demand organisations act on this subject, urging companies to outline GHG emissions throughout their value chain. This work aims to contribute to including initiatives to decarbonise the construction phase of infrastructure capital projects using the procurement process. Through a systematic literature review (SLR) and a case study applied to a Brazilian oil and gas company, the documentation related to four contract opportunities for the construction of infrastructure and offsite areas was evaluated, applying criteria raised in the literature to identify initiatives that lead to the decarbonisation during the construction phase. The study comprised interviews with experienced professionals and direct observation of the procurement process preparation of two projects. Results showed initiatives as contractual requirements targeting energy efficiency, minimising costs, and maximising productivity associated with using GHG-emitting equipment. We deliver a strategic guide for incorporating environmental sustainability initiatives with a focus on reducing GHG emissions into the processes for procuring construction services and assembling logistics infrastructure and offsite projects.
