ESG Reporting in Energy: Disclosure Requirements for Swiss Oil and Gas Companies

Environmental, social, and governance (ESG) reporting has evolved from a voluntary exercise in corporate communications to a regulatory obligation with material consequences for energy and commodity trading firms. The convergence of mandatory disclosure frameworks — from Swiss domestic requirements to EU-wide standards — demands that Swiss-based oil, gas, and energy companies develop sophisticated reporting capabilities. For an industry historically characterised by confidentiality, the shift towards transparency represents both a cultural transformation and a strategic necessity.

Swiss Regulatory Requirements

Switzerland has implemented several ESG-related disclosure obligations that directly affect energy companies:

Counter-Proposal to the Responsible Business Initiative

Following the narrow rejection of the Responsible Business Initiative in November 2020, the Swiss Parliament enacted an indirect counter-proposal that imposes binding due diligence and reporting obligations on Swiss companies. Key provisions include:

Non-financial reporting: Large Swiss public-interest companies (those exceeding specified thresholds for employees, total assets, and revenue) must publish an annual report on environmental matters, social issues, employee matters, human rights, and anti-corruption. The report must describe the company’s business model, policies, due diligence processes, outcomes, and principal risks.

Supply chain due diligence: Companies must conduct due diligence on conflict minerals and metals (tin, tantalum, tungsten, gold) and on child labour risks in their supply chains. These obligations are modelled on the EU Conflict Minerals Regulation and the Dutch Child Labour Due Diligence Act.

Climate reporting: Switzerland has adopted mandatory climate disclosure requirements based on the Task Force on Climate-related Financial Disclosures (TCFD) framework. Large Swiss companies must report on governance, strategy, risk management, and metrics and targets related to climate change. This includes scenario analysis and assessment of physical and transition climate risks.

Swiss Code of Obligations

The revised Swiss Code of Obligations (effective January 2023) codifies the non-financial reporting requirements, establishing a legal obligation for in-scope companies to report on sustainability matters in their annual reports. The reports must be approved by the board of directors and are subject to audit review.

EU Disclosure Frameworks

Swiss energy companies with operations, listings, or substantial business relationships in the EU are increasingly affected by EU sustainability disclosure requirements:

Corporate Sustainability Reporting Directive (CSRD)

The CSRD, which replaces the earlier Non-Financial Reporting Directive (NFRD), dramatically expands the scope and rigour of sustainability reporting in the EU:

Scope: The CSRD applies to all large EU companies and listed SMEs, as well as non-EU companies with significant EU turnover (exceeding EUR 150 million in the EU). This extraterritorial scope potentially captures Swiss commodity trading firms with substantial EU operations.

European Sustainability Reporting Standards (ESRS): The CSRD mandates reporting under the ESRS, which specifies detailed disclosure requirements across environmental, social, and governance topics. Energy-specific disclosures include greenhouse gas emissions (Scope 1, 2, and 3), energy consumption and mix, biodiversity impacts, and climate transition plans.

Double materiality: The CSRD requires companies to assess and report on sustainability matters from two perspectives — the impact of sustainability issues on the company’s financial performance (financial materiality) and the impact of the company’s activities on people and the environment (impact materiality).

Assurance: CSRD reports must be subject to limited assurance by an independent auditor, with a transition to reasonable assurance planned for the future.

EU Taxonomy

The EU Taxonomy Regulation establishes a classification system for environmentally sustainable economic activities. Companies subject to the CSRD must disclose the proportion of their turnover, capital expenditure, and operating expenditure associated with taxonomy-aligned activities.

For energy companies, the taxonomy presents complex classification challenges. While renewable energy generation and energy efficiency activities are clearly eligible, the treatment of fossil fuel activities, natural gas, and nuclear energy under the taxonomy has been contentious and is subject to specific technical screening criteria and transition provisions.

Sustainable Finance Disclosure Regulation (SFDR)

The SFDR imposes sustainability disclosure obligations on financial market participants and financial advisers in the EU. While primarily targeting the financial sector, SFDR indirectly affects energy companies by driving investor demand for standardised ESG data and by influencing the criteria that financial institutions use when providing trade finance, project finance, and investment capital to commodity firms.

TCFD and Climate Disclosure

The Task Force on Climate-related Financial Disclosures framework has become the de facto global standard for climate risk reporting. Swiss mandatory climate disclosure requirements, aligned with the TCFD, require companies to report across four pillars:

Governance: Disclosure of the board’s oversight of climate-related risks and opportunities, and management’s role in assessing and managing these risks.

Strategy: Description of climate-related risks and opportunities over the short, medium, and long term, and their impact on the company’s business, strategy, and financial planning. This includes scenario analysis using at least two scenarios (including a 1.5C or well-below-2C pathway).

Risk management: Description of the processes used to identify, assess, and manage climate-related risks, and how these processes are integrated into the company’s overall risk management framework.

Metrics and targets: Disclosure of the metrics used to assess climate-related risks and opportunities, including Scope 1, 2, and 3 greenhouse gas emissions, and targets used to manage these risks.

For oil and gas trading firms, Scope 3 emissions reporting — which encompasses the emissions from the use of traded products — represents a particularly significant challenge. The upstream and downstream emissions associated with traded volumes dwarf the direct emissions from a trading firm’s own operations, creating enormous Scope 3 figures that require careful contextualisation and methodology definition.

Industry-Specific Considerations

Energy and commodity trading firms face unique ESG reporting challenges:

Trading vs production: Unlike integrated oil companies, commodity trading firms do not typically own production assets. Their environmental impact is primarily associated with the products they trade (Scope 3 emissions), the vessels they charter, and the logistics infrastructure they manage. Defining the boundaries of ESG reporting for a trading firm — particularly regarding Scope 3 emissions attribution — is conceptually and practically challenging.

Carbon intensity metrics: Many ESG frameworks call for reporting of carbon intensity metrics (emissions per unit of revenue, per unit of product traded, or per unit of energy content). For diversified trading firms handling multiple products, developing meaningful and comparable intensity metrics requires careful methodology design.

Supply chain transparency: Commodity supply chains are often long, complex, and opaque. Tracing the environmental and social conditions associated with traded commodities — from production through processing, transport, and end-use — requires investment in supply chain visibility systems and supplier engagement. The sanctions compliance infrastructure that firms have developed provides a foundation for broader supply chain due diligence.

Transition planning: Energy companies are increasingly expected to develop and disclose credible transition plans that set out how they will align their business models with a low-carbon economy. For commodity trading firms, transition planning involves demonstrating how the portfolio mix is evolving — from fossil fuels towards biofuels, renewable energy, and other low-carbon commodities.

Greenwashing risk: The risk of overstating environmental credentials — whether through misleading emissions claims, inadequate methodology, or selective disclosure — is a significant concern. Regulators and civil society organisations are increasingly scrutinising corporate sustainability claims, and accusations of greenwashing can result in reputational damage, regulatory action, and litigation.

Best Practices

Leading Swiss energy companies are adopting several best practices in ESG reporting:

Integrated reporting: Embedding ESG disclosures within the annual financial report rather than publishing standalone sustainability reports, signalling that sustainability considerations are integrated into business strategy and governance.

Third-party assurance: Engaging independent auditors to provide assurance over ESG data and disclosures, enhancing credibility and supporting compliance with evolving assurance requirements.

Stakeholder engagement: Consulting with investors, regulators, NGOs, and other stakeholders to understand their information needs and to ensure that disclosures are relevant, material, and useful for decision-making.

Data systems: Investing in ESG data collection, management, and reporting systems that provide auditable, consistent, and comparable data across reporting periods and disclosure frameworks.

Continuous improvement: Treating ESG reporting as an evolving discipline that improves incrementally, rather than a one-off compliance exercise. Regularly benchmarking against peer companies and emerging best practices.

Outlook

The ESG reporting landscape will continue to tighten as Swiss and EU regulators implement more prescriptive standards, extend the scope of reporting obligations, and strengthen assurance requirements. The convergence of global sustainability standards — through the International Sustainability Standards Board (ISSB) and its alignment with regional frameworks — may eventually simplify the reporting landscape, but in the near term, companies face a complex and overlapping set of obligations.

For Swiss energy and commodity trading firms, ESG reporting is increasingly intertwined with market access, financing terms, and competitive positioning. Firms that develop robust, credible, and transparent ESG reporting capabilities will be better positioned to attract capital, maintain banking relationships, and serve customers who increasingly demand sustainability credentials from their supply chain partners.
