Legal and Compliance Priorities for Sustainability in 2026: What Businesses Should Prepare For

Sustainability and climate-related regulation are entering a more complex and demanding phase. According to a recent analysis by Ropes & Gray, 2026 is expected to be a pivotal year for sustainability, legal, and compliance professionals as governments, regulators, and investors recalibrate expectations around climate action, transparency, and corporate accountability.

The firm’s outlook identifies a set of interconnected trends that reflect both tightening rules in some jurisdictions and growing uncertainty in others. For companies pursuing net-zero targets, energy transition strategies, or sustainable finance initiatives, the coming year will require closer coordination between legal, compliance, sustainability, and finance teams.

Regulatory Fragmentation and Regional Divergence

One of the defining features of the sustainability landscape in 2026 is likely to be regulatory divergence. While some regions continue to expand climate disclosure and due diligence requirements, others are reassessing the scope and pace of ESG regulation.

In the European Union, sustainability reporting and supply chain obligations remain a central focus. Corporate Sustainability Reporting Directive style frameworks are pushing companies to provide more detailed and auditable data on emissions, climate risks, and transition plans. This is increasing the demand for robust internal controls and verifiable data systems across global value chains.

In contrast, the United States is expected to see continued legal and political debate over the role of federal climate and ESG regulation. Even where new rules are delayed or challenged, the analysis notes that enforcement activity and private litigation may fill part of the gap. As a result, companies operating across borders will need to manage overlapping and sometimes conflicting requirements rather than rely on a single global compliance approach.

Climate Litigation and Enforcement Risks

Another major theme identified for 2026 is the steady rise in climate-related litigation and enforcement actions. Regulators, investors, and civil society groups are increasingly scrutinizing climate claims, transition plans, and sustainability disclosures.

Greenwashing allegations are expected to remain a key risk area. Companies making public commitments on net zero, renewable energy sourcing, or emissions reductions will face closer examination of whether those claims are supported by credible strategies and measurable progress. This applies not only to consumer-facing statements but also to disclosures in financial filings, bond prospectuses, and sustainability reports.

The analysis highlights that legal risk is no longer limited to environmental performance alone. Governance structures, board oversight, and incentive frameworks tied to sustainability outcomes are also coming under scrutiny. Firms that cannot demonstrate clear accountability for climate and ESG decisions may find themselves exposed to regulatory action or shareholder claims.

Supply Chains, Human Rights, and Transition Minerals

Sustainability compliance in 2026 is also expected to extend further into supply chains. Companies involved in energy transition technologies such as batteries, renewable power equipment, and grid infrastructure face growing expectations around the responsible sourcing of critical minerals.

Legal and compliance teams will need to navigate requirements related to human rights, environmental impacts, and geopolitical risk in supply chains. This includes enhanced due diligence on suppliers and more transparent reporting on sourcing practices. The analysis notes that failure to address these issues could disrupt access to key materials or delay project development.

For energy and industrial companies, this trend reinforces the importance of integrating sustainability risk assessments into procurement and investment decisions rather than treating them as separate compliance exercises.

Data Quality and Assurance

As sustainability disclosures become more detailed, data quality is emerging as a core legal and compliance challenge. The outlook suggests that 2026 will see increased pressure on companies to ensure that climate and ESG data are consistent, traceable, and subject to internal or external assurance.

This shift has practical implications for net-zero strategies. Emissions inventories, transition plans, and scenario analyses must be aligned with financial reporting and risk management processes. Companies that rely on fragmented or manual data systems may struggle to meet regulator and investor expectations.

The analysis emphasizes that legal teams are playing a growing role in shaping data governance frameworks, particularly where sustainability information carries potential liability risks.

Strategic Implications for Businesses

Taken together, the predictions point to a sustainability landscape that is less about high-level commitments and more about execution, evidence, and accountability. For industries involved in energy, infrastructure, manufacturing, and finance, 2026 is likely to reward companies that invest early in governance, data systems, and cross-functional coordination.

Rather than viewing sustainability compliance as a standalone obligation, the outlook suggests integrating it into core business strategy. This includes aligning capital allocation, risk management, and executive incentives with credible transition pathways.

While regulatory uncertainty remains in some markets, the overall direction of travel is clear. Expectations around climate action and transparency are becoming more demanding, and legal and compliance functions are central to managing the risks and opportunities that come with that shift.
