Summary of results

The 25 metrics included in the assessment framework are split into three categories: target setting (“Targets”), strategies for implementation (“Strategies”), and disclosure and reporting (“Disclosure”). Target setting comprises six metrics related to emissions reductions goals and investment in clean energy. All the signatories to the OGDC are assumed to have the aim of achieving these targets; this is the category with the highest scores, but – based on the most recent publicly available reports made by companies – there is no demonstrated improvement since 2023 (Figure 2). Strategies for implementation comprise eight metrics that describe steps companies can take to achieve these targets; this was the category with the lowest scores in 2023 but also where most progress has since been made. Disclosure and reporting comprise 11 metrics allowing stakeholders to assess how companies publicly report information relevant to achieving the OGDC goals.

While the number of companies receiving full credit is fairly consistent across metrics in the targets category, there is considerably more variation in metrics related to strategies and disclosure (Figure 3). Metric 15 (annual updates) had the highest score in the assessment for the latest reporting year, with 88 companies receiving full credit. Metric 24 (CH4 investment) had the lowest score, with one company receiving full credit and six receiving partial credit.

Overall, the industry has made some progress under the assessment framework (Figure 4). The average company score has increased from 9 in 2023 to 10 based on their latest reports, and the companies improved on average for 18 of the 25 metrics. The largest relative improvement was in metric 9 on quantifying methane abatement potential (the average score improved by around 60%), followed by metric 10 on economic analysis of abatement (the average score improved by around 50%). The average score declined for seven metrics. Metric 24 (CH4 investment) featured the strongest relative decline in reporting (a 25% drop in the average company score).

Of the 113 companies assessed, 80 maintained similar scores over the period from 2023 to their latest reporting (i.e. scores changed by less than 2 points);1F1 27 companies improved their scores by 2 points or more; and five companies’ scores fell by 2 points or more. One company (GeoPark) became an OGDC signatory in December 2025 and was only assessed for the 2025 reporting year. ORLEN, which became an OGDC signatory in November 2024, recorded the largest improvement, increasing its score from 8 in 2023 to 17.5 in 2025, with all the increase coming from the strategies and disclosure categories. India’s ONGC had the largest decrease in score due to a lack of recent sustainability disclosures, going from 13.5 in 2023 to 6 in 2025; as an OGDC signatory it achieved full credit in all metrics in the targets category.

In the latest available reporting year, nine companies scored zero overall, with the 20 lowest performers improving by an average of around 0.5 points (Figure 5). Meanwhile, OGDC signatories improved from an average of 12 points in 2023 to 13 in their latest reporting.

The 12 OGCI companies averaged around 19 points out of 25, reflecting the group's decade-long focus and collaboration on emissions reductions, with their average score increasing by just over 0.5 points since 2023. OGCI members account for eight of the ten highest-scoring companies in the assessment. OGCI recently reported that its members met their 2025 upstream carbon intensity ambition, maintained methane intensity below 0.20% for the fifth consecutive year, and have set a new collective ambition of 0.10% by 2030.2F2

OGMP 2.0 members and OGDC signatories also continued to score higher than the average of all companies assessed. OGMP 2.0 members increased their average score by nearly 1.5 points since 2023, while OGDC signatories recorded an increase of just over 1 point (Figure 5).

The 35 assessed national oil companies (NOC) scored around 1.5 points lower than the average. Scores vary widely across NOCs, with five NOCs scoring zero while the top-scoring NOC (Petrobras) achieved a score of 21.5 points, tying with Shell for fifth place. The top-scoring company is Equinor, which scored 23.5 out of 25 in 2025, followed by Oxy with a score of 23, Repsol with a score of 22.5, and TotalEnergies with a score of 22.

In addition to assessing companies against the 25 metrics, this year’s report analyses, for the first time, the values disclosed by companies for key emissions and investment indicators. This provides a complementary view of how reported methane emissions, flaring, operational GHG emissions and investment have changed, alongside the trends in company scores described above.

The average methane emissions intensity of the companies that report methane emissions increased marginally from 2023 to 2025 (Figure 6). This trend should be interpreted with caution, as changes in methane intensity may reflect evolving reporting and measurement practices as well as underlying emissions performance. These factors are discussed further in the Near-zero methane by 2030 section.

Greenhouse gas (GHG) emissions intensities from scope 1 and scope 2 activities also increased slightly over the period. As with methane, this increase does not necessarily indicate a deterioration in underlying emissions performance, as changes in the reporting sample and boundaries can also affect the aggregate intensity. Methane emissions account for around 10% of total reported GHG emissions, so this increase could also be related to other factors, including changes in the energy intensity of production and differences in companies’ business activities.

Flaring intensities, on the other hand, decreased by almost 25% from 2023 to 2025. Around 50 companies reported on flaring in 2025, but many of these indicated substantial decreases in flared volumes. Eni and Perenco both reported decreases of more than 1 billion cubic metres in flaring over this period, despite increases in production; for Eni, this corresponded to a 77% reduction in flaring intensity from its 2023 level. At the aggregate level, the downward trend in company-reported flaring contrasts with World Bank estimates for the oil and gas sector as a whole, which point to an increase in flaring volumes and intensities from 2023 to 2025 (see How do company-reported flaring volumes compare with independent measurements?).

The level of investment in clean energy and operational GHG emissions reductions reported by the more than 30 companies that provided this information increased by around 65% between 2023 and 2025 (Figure 7). Trends in past investment varied significantly at company level. For example, Eni, PetroChina and TotalEnergies reported a more than two-fold increase in annual investment in clean energy and reducing operational emissions, while Chevron and bp reported a decline of more than 60%.
