Companies are under increasing pressure to prove they’re operating responsibly. Investors, customers, and regulators expect businesses to take environmental issues seriously. According to a 2023 Deloitte report, ecological risk assessments have become a core part of staying competitive and accountable.
The risks are real, and so are the consequences. Legal frameworks like the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) can hold property owners responsible for cleaning up contaminated land — even if they didn’t cause it. Imagine closing a deal only to discover your new property comes with hazardous substances and a multi-million-dollar cleanup bill.
This guide unpacks the essential steps in environmental due diligence. You’ll learn how to identify red flags, avoid unnecessary risks, and use tools like due diligence virtual data room.

What is environmental due diligence?
The environmental due diligence process presupposes investigating potential environmental liabilities linked to a property or business deal. It’s a way to uncover hidden issues that could become costly problems down the line. This process shares similarities with other due diligence practices, such as a tax due diligence report, as it aims to minimize risk and protect investments.

At its heart, this process ensures buyers, investors, or businesses have all the facts before finalizing the deal. Typically, it starts with a Phase I Environmental Site Assessment (ESA), which involves reviewing historical records, inspecting the site, and interviewing key individuals. If red flags appear, a more in-depth Phase II ESA may follow, including testing soil, water, or air for contaminants.
Why is environmental due diligence important?
Skipping the environmental due diligence assessment leads to serious consequences that go beyond your budget or timeline. Here’s why it’s crucial:
- Strengthens negotiations. Identifying environmental risks before closing gives you leverage to negotiate better terms, whether it’s a lower purchase price or having the seller address environmental cleanup costs.
- Builds customer trust. Today’s investors, partners, and customers want to work with businesses that prioritize sustainability and responsibility. 52% of consumers trust companies more when they’re transparent about their ESG priorities.
- Gives a competitive edge. Businesses that are proactive in environmental assessments are better positioned to close deals, attract investors, and maintain compliance.
- Supports strategic decisions. Understanding environmental risks allows businesses to plan effectively. Whether it’s budgeting for potential cleanup, negotiating terms, or pivoting away from high-risk deals, due diligence gives you the data needed to make confident decisions.
- Reduces long-term business risks. Environmental hazards can stretch in time and lead to ongoing costs like remediation, lawsuits, and fines.

Key steps in the environmental due diligence process
Environmental due diligence is a crucial part of any real estate or corporate transaction. It helps identify potential risks, protect investments, and ensure regulatory compliance. Let’s break down the essential steps that will guide you through an environmental due diligence audit.
Step 1: Conducting site inspections and assessments
Every due diligence process begins on-site. Environmental experts walk the property, looking for obvious signs of trouble such as leaking storage tanks, disturbed soil, or unusual odors. These inspections provide an early glimpse into potential problems.
Step 2: reviewing historical property usage
What happened on the property decades ago can have a lasting impact today. Reviewing past land uses, such as industrial operations or agricultural activities, can reveal potential contamination risks. Historical maps, aerial photos, and land use documents are valuable resources for this research.
For instance, a property that once operated as a gas station might still have underground storage tanks that could leak harmful chemicals.
Step 3: soil and water testing
Surface inspections only tell part of the story. To uncover hidden dangers, professionals collect soil and water samples for laboratory testing. These tests detect contaminants like heavy metals, hydrocarbons, or pesticides—substances that may not be visible but can cause long-term harm.
Step 4: evaluating hazardous materials and waste management
Understanding how hazardous materials and waste are managed is essential if the property is actively in use. Poor storage practices or outdated disposal methods can lead to hefty fines and cleanup costs for new owners.
Step 5: analyzing regulatory compliance
Finally, ensuring the property complies with local, state, and federal environmental regulations is essential. This includes reviewing permits, checking for past violations, and ensuring ongoing compliance. Regulatory missteps can lead to delays, fines, or even halted operations.
Pro tip: The EPA’s ECHO (Enforcement and Compliance History Online) database helps to understand a property’s compliance record.
Common risks identified during environmental due diligence
Let’s take a closer look at the most widespread natural resource environmental due diligence risks.
Contaminated soil and groundwater
Environmental risks can pose serious challenges for property buyers, often resulting in significant financial and legal burdens. Consider the Brook Industrial Park Superfund Site in Bound Brook, New Jersey. Decades of industrial activity left the soil and groundwater heavily contaminated, necessitating extensive and costly remediation led by the U.S. Environmental Protection Agency (EPA).
Hazardous waste mismanagement
Hazardous waste mismanagement is a significant risk that can lead to devastating consequences. Take the Exide lead contamination case in Vernon, California — a stark example of how improper hazardous waste disposal resulted in widespread pollution and years of costly remediation efforts. This case underscores the importance of vigilance when acquiring properties with industrial histories.
Non-compliance with air quality standards
Non-compliance with air quality standards often results in significant financial penalties and operational setbacks. In 2024, Hilcorp Energy Company faced $1.275 million in EPA penalties for Clean Air Act violations at its New Mexico facilities. Alongside the fine, the company was required to implement $1.65 million worth of compliance projects to address past emissions.
Environmental due diligence checklist
By systematically addressing reports, hazardous materials, and regulatory history, businesses minimize risks and prevent costly oversights. For instance:
- Missed environmental reports lead to overlooked contamination from past industrial use.
- Hazardous materials not identified expose the new owner to regulatory fines or cleanup obligations.
- Incomplete soil and water testing hide pollutants that impact property value or nearby ecosystems.
This comprehensive checklist helps you spot risks early and stay ahead of potential challenges. With this guide, you can make smarter investments, protect your interests, and stay on track toward long-term sustainability goals.
