Carbon footprint tender evaluation of drilling chemicals-navigating the absence of industry benchmarks

The evaluation of product carbon footprints in drilling chemical tenders has become an essential part of sustainability efforts in the oil and gas sector. However, the lack of universally accepted benchmarks complicates the tender evaluation process. This paper discusses methodological challenges and proposes a relative evaluation framework that normalizes supplier data against an internal baseline. A detailed case study illustrates how these variations can affect supplier ranking and tender outcomes, highlighting the need for industry-wide standardization to ensure fair and transparent evaluations.
