A former employee has filed a class action lawsuit against real estate giant Cushman & Wakefield, alleging the company failed to protect its workers’ retirement savings from financial risks tied to climate change. The suit claims the firm breached its legal duties by offering an underperforming investment fund that ignored environmental risks, potentially costing thousands of employees their hard-earned savings.
Understanding the Climate Risk Lawsuit Against Cushman & Wakefield
Cushman & Wakefield, one of the world’s largest commercial real estate services firms, is now at the center of a groundbreaking legal battle. A former employee, Renee Kvek, filed a class action lawsuit on March 4, 2026, alleging that the company’s 401(k) plan fiduciaries neglected their responsibility to monitor and manage “material climate-related financial risks.”
This case is being watched closely by legal experts and consumer advocates alike because it marks a “first-of-its-kind” challenge under federal law. At its heart, the lawsuit argues that climate change isn’t just an environmental issue—it is a financial one. When a company manages a retirement plan, they have a “fiduciary duty” to act in your best interest. The plaintiff alleges that by ignoring how climate change impacts certain stocks, Cushman & Wakefield put your retirement security at risk.
The lawsuit specifically targets the inclusion of the Westwood Quality SmallCap Fund in the company’s retirement offerings. According to the complaint, this fund was “openly indifferent to climate risk,” meaning its managers did not properly account for how shifting environmental regulations, physical climate disasters, or the global transition to a green economy might devalue the companies within the fund.
Who May Be Eligible to Join the Cushman & Wakefield Class Action?
Class action lawsuits are powerful because they allow individuals to band together against large corporations. Instead of one person fighting a multi-billion dollar firm, thousands of people stand together to demand justice.
In this case, the proposed class includes a significant number of people. As of the end of 2024, the Cushman & Wakefield retirement plan reportedly had over 23,000 participants and held approximately $1.7 billion in assets.
You may be eligible to participate if:
- You are a current or former employee of Cushman & Wakefield.
- You participated in the company’s 401(k) retirement plan.
- You were invested in the Westwood Quality SmallCap Fund at any time between January 2021 and the date a final judgment is reached in the case.
If you fit these criteria, your retirement savings may have been affected by the alleged lack of climate risk oversight and the subsequent underperformance of the fund. At this stage, the lawsuit is seeking to represent all participants and beneficiaries who were impacted during this timeframe.
How Your Retirement Savings May Be Impacted by Company Decisions
When you contribute to a 401(k), you trust that the options provided by your employer have been vetted for safety and growth. You aren’t just picking a name off a list; you are relying on the expertise of the plan’s administrators to ensure those investments are sound. This lawsuit suggests that for thousands of Cushman & Wakefield employees, that trust may have been misplaced.
The complaint alleges that the Westwood fund in question underperformed significantly compared to broader market benchmarks, like the Russell 3000 index. Specifically, the suit claims the fund trailed behind by wide margins over one, three, five, and 10-year periods. In 2025 alone, the fund reportedly underperformed the index by more than 17%.
For everyday people, these percentages translate into real dollars missing from a future retirement. If an employer keeps an underperforming fund in the lineup without a clear reason or fails to account for modern risks like climate change, they may be failing in their duty to help you grow your nest egg. This legal action seeks to hold companies accountable for every detail of their retirement plan management, ensuring they don’t overlook the “discrete concern” of climate-driven financial instability.
Breaking Down the ERISA Violations and Your Legal Protections
The lawsuit is built on the Employee Retirement Income Security Act of 1974, commonly known as ERISA. This is a federal law that sets minimum standards for most voluntarily established retirement and health plans in private industry. It was designed to protect people like you from the mismanagement of funds.
Under ERISA, those who manage 401(k) plans—the “fiduciaries”—must act with “prudence” and “loyalty.” The lawsuit against Cushman & Wakefield alleges three specific counts of ERISA violations:
- Breach of Fiduciary Duty: Failing to select and monitor plan investments prudently and in the best interest of the workers.
- Prohibited Transactions: Allegations regarding the way certain transactions within the plan were handled.
- Failure to Monitor: A claim that those at the top of the company failed to properly oversee the individuals specifically tasked with managing the 401(k) investments.
The legal team representing the plaintiff, which includes the environmental legal nonprofit ClientEarth and the law firm Cohen Milstein, argues that climate risk management is no longer optional. They believe that because climate change is “financially substantial” and “escalating,” it is a mandatory component of a fiduciary’s job to evaluate it.
The Contrast Between Corporate Sustainability and Employee Investments
One of the most striking allegations in the lawsuit is the perceived gap between what Cushman & Wakefield says publicly and what it does with its employees’ money. The complaint points out that for decades, the firm has positioned itself as a leader in sustainability, claiming to embed climate considerations into the very core of its business operations.
However, the lawsuit alleges that this commitment stopped at the door of the HR department. Renee Kvek, the lead plaintiff, expressed disappointment at learning how exposed her savings were to climate risks, especially since the company appeared to understand those risks so well in other areas of its business.
“When your employer offers you a set of retirement options, you assume they’ve done the work to make sure those options are sound,” Kvek said in a statement. This sentiment reflects the core of consumer advocacy: the belief that everyday people deserve transparency and consistency from the corporations they work for and invest in. If a company recognizes a risk as “material” to its business, it should logically recognize that same risk as material to its employees’ investments.
How to Take Action and Protect Your Retirement Future
When a major corporation is accused of failing its employees, it is important to stay informed and understand your rights. This case against Cushman & Wakefield is in its early stages, but it serves as a wake-up call for anyone with a workplace retirement account.
If you believe your 401(k) or retirement savings have been mismanaged, or if you are a current or former Cushman & Wakefield employee who invested in the Westwood Quality SmallCap Fund, you may have legal options. There is no obligation to reach out, and many of these cases are handled on a contingency basis, meaning there are no out-of-pocket costs to you.
