ESG Legal Requirements: What Law Firms Need to Know

What are ESG legal requirements?

ESG legal requirements establish legal standards across a variety of environmental, social, and governance issues. These requirements serve multiple purposes, (1) ensure investors have material information about ESG-related risks, (2) mandate transparency about supply chain practices, and (3) set performance standards in areas like data privacy and workplace safety. 

Environmental legal requirements include ones pertaining to carbon emissions, sustainability reporting, environmental impact, and renewable energy. Other environmental laws control recycling, water usage, and logging. For instance, the EU timber regulation requires companies to assess and mitigate the risk of illegal timber in their supply chain.
Social legal requirements touch upon issues such as workplace diversity, labor practices, and the human rights of workers involved in supply chains. For example, laws like the UK Modern Slavery Act and the California Transparency in Supply Chains Act require companies to report on steps taken to eradicate slavery and human trafficking in their supply chains. 
Governance laws define standards relating to board accountability, data privacy, and shareholder rights, among other issues. Example laws include the Canada Business Corporations Act, which gives shareholders the right to examine corporate records, including minutes of meetings containing director conflict disclosures.

ESG laws aren’t the only source of pressure on companies to implement ESG programs; investor demands and client expectations are also a strong incentive.

Why ESG legal requirements matter to law firms

The growing complexity of ESG laws means companies need law firm help in navigating the legal maze, and law firms must ensure their own ESG adherence as part of their overall law firm compliance requirements.

As legal advisors, law firms must guide clients in complying with ESG legal requirements relating to disclosure, reporting, and ESG risk management. For example, companies in Europe often need guidance in meeting the requirements of the EU’s Corporate Sustainability Reporting Directive (CSRD). Under the CSRD, companies must report detailed information on their ESG performance.

At the same time, in their role as businesses, law firms must comply with ESG laws and regulations relating to sustainability, employment, and governance. In California and New York, for example, law firms must comply with state laws like the California Consumer Privacy Act (CCPA) and the New York SHIELD Act, which mandate stringent measures to protect client data from breaches.

Law firm noncompliance creates the risk of legal penalties and reputational harm, as well as loss of client goodwill. Corporate clients expect firms to prioritize ESG principles and often ask for firms to highlight in Requests for Proposals (RFPs) their efforts relating to ESG compliance.

How ESG affects law firms internally

What do the details of ESG compliance look like at law firms? Below are a few issues that law firms must address in each ESG standard:

Environmental impact 

Consider a UK law firm that is subject to the UK’s Streamlined Energy and Carbon Reporting law, which requires large companies, including large law firms, to disclose actions they’ve taken to improve energy efficiency. Such a firm might point to a new remote work policy, which is reducing office and transportation energy. The firm might also describe office sustainability measures, such as lights that shut off automatically if there’s no motion detected.

Similarly, in the EU, the CSRD requires certain large companies, including large law firms, to report on their sustainability performance, including their environmental impacts and climate change mitigation plans.

Social responsibility

In Canada, law firms must comply with provincial human rights and employment standards acts, which prohibit discrimination and harassment based on factors like race, gender, disability, and age. To comply with these laws, Canadian firms develop policies, training and education programs, and internal enforcement processes. 

Law firms in Canada, the US, and Europe also comply with laws relating to employee well-being, such as Provincial Occupational Health and Safety (OHS) laws in Canada, the Occupational Safety and Health Act in the US, and the EU’s Working Time Directive, which sets rules for working hours, rest periods, and paid annual leave for workers within the EU. 

Depending on the jurisdiction, compliance with these laws can involve controlling common psychological hazards like unsustainable workloads, creating policies that establish boundaries for after-hours communications, and providing access to Employee Assistance Programs.

Governance and compliance 

Most jurisdictions have adopted governance standards focused on data protection. In Europe, firms are subject to the General Data Protection Regulation (GDPR). In Canada, the Personal Information Protection and Electronic Documents Act (PIPEDA) controls, and in the US, a patchwork of sector-specific and state-level regulations govern data protection at law firms. 

Choosing the right software is critical to protecting client data and complying with these standards. Clio products comply with SOC 2 and GDPR standards, helping firms uphold their governance and data privacy obligations.

ESG compliance challenges for law firms

As the above examples show, to comply with ESG laws, law firms must create and implement multiple policies, processes, and programs. Further complicating compliance is that each office of a multi-jurisdictional firm has to track and comply with different ESG standards. The burden of compliance only grows if a firm uses general-purpose software for tedious manual reporting and documentation.

Law firms also face the challenge of accurately communicating to prospective clients the full breadth and impact of their ESG efforts. In an era when clients are on guard against potential greenwashing, law firms can inspire the greatest confidence in their ESG commitment with transparent, public policies and credible reports.
