The pressure to decarbonise the upstream and refining sectors continues to mount. As carbon pricing evolves and producers cut emissions for oil and gas operations, the impact of carbon intensity (CI) on crude differentials will be felt. To evaluate the CI of crude, it is essential to define the emission boundary as market participants decide which parts of the value chain to invest in. In this insight, we look at the following aspects: • Evaluate full value chain CI of key benchmark crude grades in different refinery configurations • Define potential benchmark ranges to categorise CI of crude • Compare the CI of benchmark grades across different parts of crude value chain • Estimate crude price differentials emerging from the CI values across the value chain at different carbon price • Demand drivers for low-carbon crude with a case study for CORSIA eligible fuels View the insight to find out more.
