In June 2019, the UK government legislated a net zero target by 2050. This will directly impact the UK oil and gas industry. This study reports perceptions of key oil and gas professionals regarding the impact of transitioning to net zero on impairment, values, write-downs, and going concern in the UK oil and gas industry, as well as required net-zero-related disclosures. Data were collected through 22 interviews, two written responses to our interview questions, and disclosures made by oil and gas companies in their annual reports. We use conservatism and stakeholder theory to inform our results. Our findings confirm there will be serious impacts of the transition to net zero on impairments, asset write-downs, and on the value and going concern of several oil and gas companies. However, these impacts will not fall equally across the industry, and it is likely therefore that stakeholders will be affected differently. Our results contribute, first, to the debate on the impacts of the transition to net zero on key accounting measures of oil and gas companies; second, we identify risks associated with the transition to net zero for these companies and their stakeholders, and we classify the at-risk oil and gas companies operating in the UK; third, we present a collection of disclosure items deemed necessary by our interviewees. Our specified disclosure items may complement those of the Task Force on Climate-related Financial Disclosures (TCFD) and the Transition Plan Taskforce (TPT).
