Corporate Sustainability in Practice – How Contracts Shape Responsibility

From Reporting to Governance and Risk Allocation

Environmental, Social and Governance (ESG) considerations are playing an increasingly influential role in how businesses operate, invest, and manage risk, especially within the European Union, where corporate sustainability and responsibility regulation have been on the agenda in recent years.

With the adoption of the Corporate Sustainability Reporting Directive (CSRD) and the Corporate Sustainability Due Diligence Directive (CSDDD), many companies anticipated a significant shift in compliance. Since then, the EU has introduced simplification measures to streamline reporting and due diligence obligations, reduce the administrative burden, and improve proportionality, particularly for small and medium-sized enterprises (SMEs), while maintaining the core sustainability objectives.

While opinions may differ regarding the evolution of environmental, social, and governance (ESG) in EU regulation and the subsequent postponements of reporting obligations, regulatory developments appear to have, in practice, supported a shift in perspective. Sustainability is no longer viewed solely as a reporting requirement, but increasingly as a matter of governance, strategy, and risk allocation. This development is welcome, as the regulatory framework’s underlying objective is to advance the green transition, which in turn requires a change in how companies integrate sustainability into their decision-making and operations.

This focus on sustainability influences businesses of all sizes, including SMEs. Even companies not directly subject to the CSRD or CSDDD anticipate that ESG requirements will be passed down through the supply chain. Many non-reporting SMEs are already embedding sustainability practices, and this trend is likely to continue. In other words, sustainability policies are already affecting companies well before any formal reporting obligations kick in.

Environmental, Social, and Governance in Contract Architecture

One of the key means of implementing environmental, social, and governance obligations and objectives in day-to-day business operations is through commercial contracts and the requirements and commitments embedded in them.

Even where a company itself is not directly subject to extensive reporting or due diligence obligations, corporate sustainability and responsibility expectations flow through the market via contractual relationships. Larger undertakings within the scope of CSRD and, in due course, the CSDDD require contractual assurances, information rights, and cooperation from their business partners, including SMEs operating within their supply chains. As a result, corporate sustainability and responsibility become a question of contractual architecture. Companies must consider not only price mechanisms, liability caps and termination triggers, but also how environmental, social and governance risks and obligations are addressed and allocated between the parties through legally enforceable contractual terms.

Translating Policies into Binding Obligations

A typical starting point is the incorporation of a code of conduct or sustainability policies into commercial contracts, often by reference and through an express obligation on the contracting party to comply with them. From a legal standpoint, this raises important drafting questions. Many codes are drafted as high-level public statements. When such policies are converted into contractual commitments, their wording, scope, and hierarchy relative to the main agreement require careful consideration. The obligations must be sufficiently clear to define the parties’ expectations, coherent with other contractual provisions, and proportionate to the commercial relationship. The obligations must also be capable of practical implementation and effective monitoring in the context of the agreement.

In practical terms, this may mean requiring the supplier to comply with specific labour standards, maintain documented environmental management procedures, report on emissions data, ensure traceability of key raw materials, or allow reasonable access for audits. Clearly defining what is expected, how compliance is demonstrated, and what consequences follow from non-compliance is essential for the clause to function effectively. Otherwise, clauses that appear comprehensive in theory and ambitious in scope may offer limited enforceability in practice, and their impact may remain marginal if compliance cannot be effectively monitored and verified. If policies are not properly translated into binding and operational obligations, the company risks a mismatch between what it promises publicly and what is actually required under its contracts. This may undermine consistency, weaken risk management, and expose the company to reputational and governance risks if its own stated principles cannot be enforced within its supply or distribution chain.

As part of this process, companies must also consider the protection of trade secrets and confidential information. For example, broad audit or data-reporting obligations may raise concerns about sensitive business information. Contractual terms should balance transparency with the need to protect legitimately proprietary data. Clauses such as confidentiality agreements or carve-outs for trade secrets can be used to ensure that sharing ESG-related information does not compromise confidential business information or competitive advantages.

Environmental, Social and Governance Clauses Across Different Contract Types

Besides codes of conduct and sustainability policies, environmental, social and governance-related clauses increasingly take more tailored and transaction-specific forms. In shareholder agreements, sustainability objectives may be reflected in governance structures or even linked to financial outcomes, for example by aligning dividend policies or incentive mechanisms with agreed climate targets. In employment contracts, obligations may extend beyond general compliance and include participation in corporate sustainability training programmes or adherence to internal sustainability guidelines as part of performance expectations.

In supply and manufacturing agreements, environmental, social and governance provisions may address traceability of raw materials, emissions reporting, waste management, energy efficiency standards or the right to replace a supplier if its environmental practices materially conflict with the contracting party’s sustainability commitments. Such contractual mechanisms increasingly affect SMEs operating as suppliers, as ESG expectations pass through the supply chain.

Construction contracts often include detailed requirements regarding material selection, lifecycle impacts, carbon footprint calculations and recycling or waste reduction procedures. For example, in Finland, legislation imposes low-carbon and energy efficiency requirements for new buildings, and a party undertaking a construction project is subject to mandatory reporting obligations relating to construction and demolition waste. These statutory requirements are typically reflected and implemented in the relevant project and construction contracts.

Across these different contract types, the practical significance is consistent. Environmental, social and governance considerations move from the level of general policy into legally enforceable obligations tailored to each specific legal relationship. Contracts function as a mechanism for allocating responsibility, managing compliance risk and aligning commercial incentives with sustainability objectives.

Proportionate Monitoring and Audit Rights

In the contractual implementation and monitoring of environmental, social and governance obligations, audit and information rights play a central role. They are closely linked to effective oversight and form an integral part of a coherent contractual framework. In practice, companies typically seek access to relevant data from their business partners and, where appropriate, establish inspection or audit rights to enable meaningful monitoring and verification, whether conducted directly by the company or, commonly, by an independent expert appointed for that purpose.

However, such arrangements must remain balanced. Overly burdensome provisions may needlessly disrupt day-to-day operations and reduce the willingness to cooperate, particularly for SMEs with limited administrative capacity. By contrast, well-designed mechanisms that balance transparency with confidentiality and operational feasibility are more defensible and more likely to function effectively in practice.

Contractual Remedies

As a general principle, the consequences of a breach are determined by the terms agreed between the parties. In practice, the parties will typically first seek to resolve the matter through discussion and good faith negotiations, allowing the non-compliant party an opportunity to clarify the situation and implement corrective actions within a reasonable timeframe. If negotiations do not lead to a resolution, it may be appropriate to proceed to stronger measures, such as contractual penalties, indemnification obligations, price adjustments, temporary suspension rights or other agreed sanctions, applied in light of the nature and severity of the breach.

The contract should clearly define what constitutes a breach, how it is assessed and what remedies are available in each scenario. Clear and proportionate step-by-step remedy structures enhance legal certainty, reduce the risk of disputes and ensure that material or repeated breaches may trigger more significant consequences, including termination where justified.

Strategic and Voluntary Environmental, Social and Governance Commitments

In the current EU landscape, implementing ESG considerations in commercial contracts is no longer simply a matter of reacting to directives. It is a broader exercise in risk management and corporate governance. Even as the implementation details of the directives may continue to evolve, market expectations, financing conditions and reputational considerations remain key drivers of sustainability integration.

In addition, some companies choose to position themselves as frontrunners in sustainability for strategic and reputational reasons. They may therefore incorporate voluntary environmental, social and governance mechanisms and requirements into their contracts that go beyond, or are not directly derived from, binding directives. By doing so, they signal to investors, customers and other stakeholders that sustainability is treated as a core business priority rather than merely a compliance obligation.

At the same time, it is important to recognise the practical limits of such commitments. Ambitious sustainability requirements may be more challenging for SMEs with limited financial and administrative resources. Meeting extensive reporting, certification or traceability standards can require investments in systems, personnel and external expertise. If contractual expectations are not calibrated to the size and capacity of the counterparty, they may limit the ability of SMEs to participate in certain supply chains. A balanced and proportionate approach helps ensure that sustainability objectives remain achievable and commercially workable across the contractual chain.

Conclusion

For legal practitioners, the central task is not to increase the number of environmental, social and governance clauses as such, but to ensure their quality, coherence and practical relevance. The objective is to design contractual mechanisms that are proportionate, enforceable and aligned with the company’s actual risk profile, industry context and sustainability priorities. Commercial contracts remain one of the most concrete tools for translating sustainability strategy into operational practice. Moreover, every contract lawyer should understand and apply key sustainability principles in their work, ensuring that ESG commitments become integral to legal advice and contract drafting.
