The conflict between Russia and Ukraine, along with the imposition of energy sanctions on Russian energy sources, has prompted a reassessment of the global energy market. Utilizing the difference in differences model, this study investigates the financial performance disparities among fossil fuel companies operating within the EU-27 bloc, Russia, and countries such as the United States, the United Kingdom, Qatar, Norway, India, China, UAE, and Saudi Arabia (countries that have benefitted from exporting fossil energy to the EU-27 as an alternative to Russia) during the period spanning from 2016 to 2023. The result reveals that fossil fuel companies from the United States, the United Kingdom, Qatar, Norway, India, China, UAE, and Saudi Arabia experienced significant advantages from substituting Russia in supplying oil, natural gas, and LNG to the EU-27. This is evidenced by a notable enhancement in their financial performance compared to both Russian and EU-27-based fossil fuel companies. For fossil fuel companies, the study highlights the urgency of diversifying export and import markets, broadening partnerships for fossil fuel trading and refining, transitioning to the production of lower-emission energy forms, and enhancing sustainable development practices to mitigate risks. At the national level, the research results indicate that countries reliant on imported fossil energy, akin to most countries within the EU-27, must swiftly diversify their energy sources and focus on developing renewable energy. This strategy is crucial to avoid unexpected shocks in the energy market in the era of geopolitical conflicts and uncertainty.
fossil fuel, fossil energy, energy security, EU-27, Russian energy sanctions, Russia–Ukraine conflict
The ramifications of the Russia–Ukraine conflict prompted a series of punitive sanctions against the Russian energy sector, posing challenges to energy policies across the European Union (EU-27) member states. As reported by
Despite widespread efforts to foster renewable energy sources, fossil fuels are anticipated to remain the primary energy source in Europe in the foreseeable future (
On the other hand,
The results of this study, from a microeconomic perspective, will enable fossil fuel companies to assess potential risks in the context of significant unexpected disruptions. This will allow them to prepare strategies such as diversifying export and import markets, broadening partnerships for fossil fuel trading and refining, transitioning to the production of lower-emission energy forms, and enhancing sustainable development practices to mitigate risks. From a macroeconomic perspective, the study holds policy implications for both exporting and fossil fuel-dependent countries in economic development. In an era marked by geopolitical conflicts and instability, the research underscores the necessity for countries to diversify their energy sources, particularly by encouraging the increased production of renewable energy, to ensure energy independence.
The impact of war and geopolitical conflict on the fossil energy sector is a subject of substantial scholarly inquiry, characterized by a multifaceted array of effects that reverberate across global energy systems. Such events invariably disrupt the production, transportation, and availability of fossil fuels, engendering supply shortages and price volatility within international energy markets (
Energy security refers to the uninterrupted availability of energy resources at affordable prices to meet the needs of a nation’s economy and population (
The sanctions instituted by the European Union against Russia in response to its conflict with Ukraine were initiated in 2014. Nevertheless, owing to the European Union’s reliance on Russian energy resources, sanctions targeting fossil fuels have demonstrated limited efficacy (
In 2022, driven by opposition to Russia amidst the current conflict, a majority of EU member states and their Western counterparts opted to intensify sanctions against Russia to unprecedented levels (
However, recent studies have indicated that the European Union’s energy strategies have not yielded the anticipated outcomes. Conversely, the EU has incurred losses in both its overall economy and the energy sector specifically (
Viewed through a microeconomic lens, there exists a paucity of research delineating variances in the performance of European enterprises pre- and post- the Russia–Ukraine conflict and ensuing sanctions. Predominantly, scholarly investigations concentrate on the examination of stock price shocks and abnormal returns (
Since the Russia–Ukraine conflict and the unprecedented sanctions against Russian energy, numerous studies have been conducted to examine the impact of these events on various stakeholders. Most of these studies focus on the macroeconomic perspective. For example,
To date, we have found that almost no research has addressed a very urgent issue: “How fossil fuel companies operate in the context of the Russia–Ukraine conflict and Russian energy sanctions, especially when considering fossil fuel companies from countries with different interests?” Therefore, in this study, we categorize fossil fuel companies into three groups: the EU-27, Russia, and alternative exporting countries (this group includes the United States, the United Kingdom, Qatar, Norway, India, China, UAE, and Saudi Arabia; in other words, these are countries that have benefited from exporting fossil energy to the EU-27 as an alternative to Russia). We then compare the financial performance of fossil fuel companies from these three groups in pairs. Based on the analyses, we propose the following research hypotheses:
H1: The financial performance of fossil fuel companies from alternative exporting countries tends to show better growth compared to those from the EU-27 and Russia.
H2: Fossil fuel companies from both the EU-27 and Russia have encountered difficulties due to the sanctions targeting the Russian energy sector.
In this study, we selected oil and gas companies to represent fossil fuel companies in general. In the EU-27 region, the chosen companies are key players in their respective countries and the EU region, such as TotalEnergies, Repsol, Eni, Uniper, etc. In countries with increased fossil fuel exports to the EU, including the UK, the US, Qatar, Norway, China, Saudi Arabia, UAE and India, we only selected fossil fuel companies operating within the EU or exporting gas, oil, and LNG to the EU region, such as Chevron, ExxonMobil, Shell, Equinor, Indian Oil Corporation, QatarEnergy, etc. For the case of Russia, only key players such as Gazprom, Rosneft, Lukoil, etc. are chosen. Additionally, since our study spans from 2016 to 2023, fossil fuel companies must have financial data for the year 2023. In total, we selected a study sample consisting of 77 companies from the EU-27 region and 93 companies from the group of alternative exporting countries and 31 companies from Russia (Table
To explore the financial performance disparity between fossil fuel companies within the EU-27 region and those in areas benefiting from increased fossil fuel exports to the EU — such as the UK, the US, Qatar, Norway, and India — amidst the Russia–Ukraine conflict and sanctions on Russian energy, we consider the adoption of Average Treatment Effect (ATE) and Average Treatment Effect on the Treated (ATT) as potential analytical metrics. The ATE denotes the average causal impact of a treatment or intervention across the entire population, encompassing both treated and untreated individuals, thereby gauging the overall influence of the treatment regardless of treatment receipt. This metric quantifies the mean difference in outcomes between entities subjected to the intervention and those assigned to the control (placebo) group (
The identification of Average Treatment Effect on the Treated (ATT).
Source: Compiled by the authors.
Yist = ∝s + ∝t + Zist β + Dst δ + εist, (1)
where: Yist is the outcome of the i-th observation in group s at time t; ∝s are group fixed effects; ∝t are time-fixed effects; Zist are covariates; β are the coefficients on the covariates; Dst is the (time-varying) treatment indicator; δ is the coefficient on the treatment indicator, i.e., the ATT, and εist are the residual errors.
The identification of the ATT hinges upon maintaining the parallel trends assumption. This assumption posits that the trajectories observed in both the treated and control groups exhibit similarity prior to the intervention, and in the absence of it, these trajectories would have persisted unchanged. It serves as a crucial assumption for identifying treatment effects, as estimations of such effects become untenable if this assumption is violated. Directly assessing this assumption proves impractical, given the inability to ascertain the hypothetical outcomes in the absence of intervention. Indirectly gauging this assumption typically involves scrutinizing whether trends preceding the intervention are congruent or, at the very least, comparable. The rationale underlying this approach is that if pre-treatment trends demonstrate consistency, they would likely follow similar trajectories in the absence of intervention.
Testing for parallel trends. Testing for parallel trends is a critically important procedure for examining the validity of the estimated ATT. The results of parallel trend tests are interpreted from the linear-trends model and the Granger model. For the linear-trends model, we first rewrite equation (1) as:
Yist = DIDist + εist. (2)
The linear-trends model augments the above model with two more terms:
Yist = DIDist + wi dt,0 t ϑ1 + wi dt,1 t ϑ2 + εist. (3)
The augmentation terms consist of two 3-way interactions between dt,0, wi and t, and dt,1, wi and t. dt,0 = 1(dt = 0) is a variable indicating pretreatment periods; dt,1 = 1(dt = 1) indicating post-treatment time periods. wi = 1 if ever treated, and 0 if never treated. The coefficient ϑ1 captures the differences in slopes between the treatment group and control group in pre-treatment periods, while ϑ2 captures the differences in slopes in post-treatment periods. If ϑ1 is 0, the linear trends in the outcome are parallel during pre-treatment periods. In this context, we employ a Wald test of ϑ1 against 0 to assess whether the linear trends are parallel prior to treatment. The DID variable is formulated as the product of Time multiplied by Treatment. In this context, Time represents a binary indicator, assuming a value of 0 if the observation occurs before the intervention year and 1 if it occurs after the intervention year. Similarly, Treatment is also a binary indicator, assuming a value of 0 for observations in the control group and 1 for observations in the treatment group. Consequently, the DID variable is likewise a binary indicator, assuming values of either 0 or 1.
The dependent variables in the model encompass financial metrics such as Return on Equity (ROE) and Return on Assets (ROA). As for the independent variables related to financial aspects, they include the current ratio, total assets, debt to equity ratio, debt to assets ratio, revenue, and Cost and Expenses. Regarding company-specific characteristics, the independent variable operational age is utilized. Additionally, macro-level control variables incorporated in the model encompass the GDP growth rate and government subsidy rate during the COVID-19 pandemic period (Table

The results of the parallel trends test indicate that the assumptions regarding the trends in ROE and ROA for fossil fuel companies in models 1, 2, 3, 4, 5, and 6 suggest that the trends in financial performance for the three groups (EU‑27, Russia, and alternative exporting countries) were parallel before the treatment year, validating the appropriateness of employing the ATT analysis.

Robustness tests. To ensure the robustness of our findings, we conducted a series of tests. Notably, within the alternative exporting countries group, a considerable proportion of observations, comprising 38 companies, originated from the United States, representing 41% of the sample in the group. Recognizing the potential for overrepresentation resulting from this distribution, we undertook robustness assessments across models 7, 8, 9, 10, 11, 12, 13, 14. In models 7 and 8, we conducted ATT analysis for both ROE and ROA, focusing on fossil fuel companies within the EU-27 bloc and those from the United States. In models 9 and 10, we performed ATT analysis for ROE and ROA concerning fossil fuel companies within the EU-27 bloc and a cohort of selected countries, encompassing the UK, Qatar, Norway, India, China, UAE, and Saudi Arabia. Similarly, in models 11 and 12, we conducted ATT analysis for both ROE and ROA, focusing on fossil fuel companies within Russia and those from the United States. In models 13 and 14, we performed ATT analysis for ROE and ROA concerning fossil fuel companies within Russia and a cohort of selected countries, encompassing the UK, Qatar, Norway, India, China, UAE, and Saudi Arabia. Importantly, the outcomes of the ATT analysis and the parallel trends test remained consistent with those derived from models 1, 2, 5 and 6, reinforcing the validity and coherence of our previous analyses (Tables

Therefore, based on the results of the ATT analysis and the robustness tests, we conclude the research hypotheses that fossil fuel companies from alternative exporting countries are the primary beneficiaries in the context of the volatile energy market resulting from the Russian energy sanctions. Both fossil fuel companies from the EU-27 and Russia exhibit similar fluctuation trends before and after 2022, indicating no clear advantage between these two groups. While Russia seeks new import partners, the EU-27 must explore new partners for purchasing or collaborating in the production of fossil fuels.
Drawing from the analyzed data in sections 1–2, and the research findings in section 4, we aim to discuss the following key issues.
From the perspective of fossil fuel companies, our analysis indicates that prior to 2022, Russian fossil fuel companies consistently outperformed companies from the EU-27 and alternative exporting countries in terms of financial performance indicators such as Return on Equity (ROE) and Return on Assets (ROA). This trend persisted even amidst the significant downturn in global oil and gas industry profits in 2020 (
At the national level, in accordance with the latest European Council report (2024), the proportion of natural gas supplied via pipelines from Russia to the EU experienced a notable decline, dropping from over 40% in 2021 to approximately 8% by 2023. This reduction is further pronounced when considering both pipeline gas and LNG, with Russia’s contribution accounting for less than 15% of the EU’s total gas imports. This trend is viewed within the EU-27 countries as a symbolic victory in their strategic pursuit of energy decoupling from Russia in forthcoming scenarios. However, mitigating reliance on Russian energy does not inherently guarantee immediate energy security for the EU-27 bloc. According to the “2023 Report on energy subsidies in the EU” by the
In the case of EU countries during the 2022 energy crisis, it is noteworthy that they had to significantly increase energy subsidies for transportation by 280% and subsidies for heating and household utilities by 500% in 2022 (
Researching the impact of war and geopolitical conflict on the fossil energy sector and energy policy holds significant scholarly importance owing to its multifaceted implications. By delving into this subject matter, scholars can gain insights into the vulnerabilities inherent in energy supply chains disrupted by geopolitical tensions and armed conflicts. Through rigorous analysis, researchers can assess the associated risks, thereby aiding policymakers in formulating effective strategies to mitigate them and ensure energy resilience. In terms of policy implications, our study provides crucial empirical evidence for fossil fuel companies’ managers to diversify export and import markets, broaden partnerships for fossil fuel trading and refining, transition to the production of lower-emission energy forms, and enhance sustainable development practices. At the national level, in the near future, most countries will still need to rely on fossil fuels for economic development. Therefore, diversifying fossil fuel import and export sources is crucial to ensure the stability of these fuel supplies. Securing energy for consumption and production is vital for every country, making it essential to seek and collaborate with reliable partners as a key national policy, rather than merely a business strategy for fossil fuel companies. We believe that the trend of forming alliances based on fossil fuel interests is inevitable in the coming years. In the long term, to ensure energy security and move towards sustainable development, it is necessary for each country to implement subsidy policies and increase the share of renewable energy in their energy consumption mix.
Although our study does not comprehensively cover and explain the absolute energy security of the EU as a whole and the performance of fossil energy companies within the EU specifically in the context of the current geopolitical conflict, and sanctions, it derives its findings from an examination of energy import policies and subsidies for fossil fuels within the EU bloc, as well as disparities in the financial performance of fossil fuel companies within the EU and the group of countries benefiting from exporting fossil fuels to the EU since the Russia–Ukraine conflict and energy sanctions on Russian fossil fuels. Through this analysis, we have contributed insights to address one of the most pressing issues today: “Who truly benefits from the EU-27’s energy decoupling from Russia?” In the future, we believe that it is possible to expand the research by comparing the performance and subsidies of the fossil fuel sector and the renewable fuel sector by governments of countries within the EU-27 before and after the Russia–Ukraine conflict, thereby providing further empirical evidence on the transformation and adaptation of energy security and climate policies of the EU-27 bloc in the era of geopolitical conflict and uncertainty.
Limitations of the study. Since this research primarily focuses on explaining the trends in the financial performance of fossil fuel companies from the EU-27, Russia, and alternative exporting countries during 2022–2023, under the condition that the trends in financial performance of these three groups are similar, it does not provide detailed explanations for the financial performance of fossil fuel companies during the 2016–2021 period, especially during the COVID-19 pandemic. Furthermore, although we consider this an opportunity for renewable energy to demonstrate its importance and increase its share in the energy mix as a crucial national energy policy, we have not yet provided an answer to whether renewable energy companies truly performed effectively compared to fossil fuel companies during 2022–2023. We hope that future research can address these limitations.
