How Facility Managers Can More Accurately Report ESG-Compliant Furniture Retirement Data

The United States generates more than 12 million tons of furniture waste annually, with approximately 9 million tons ending up in landfills, equivalent to the weight of 90,000 blue whales. As landfill space becomes increasingly scarce and disposal costs continue to rise, furniture waste has become a dual challenge involving both environmental and financial concerns. Many businesses have yet to realize that reusing or recycling waste is actually less costly than landfilling or incineration.

This is not to say that furniture reuse or recycling is without obstacles, but the cost and environmental benefits make overcoming these obstacles worthwhile, especially considering the climate benefits of reuse.

Imagine this scenario: you are overseeing a 50,000-square-foot office renovation project. The leadership team wants compelling stories and sustainability metrics in the annual report, including cost savings, of course. You develop a decommissioning plan that includes donating usable furniture to local nonprofits, reselling high-value items, and recycling parts that cannot be reused. On paper, you seem to have covered all bases.

But the reality is that the U.S. Environmental Protection Agency's (EPA) Waste Reduction Model (WARM)—the tool most facility managers rely on—accounts for less than 10% of the actual climate benefits. That is not a typo.

Research from Bard College found that WARM captures only a fraction of the greenhouse gas emissions avoided when office furniture is reused rather than landfilled. It completely ignores the upstream emissions avoided by not having to procure, manufacture, and transport replacements. For example, donating 100 chairs not only prevents them from entering landfills but also prevents the carbon footprint of producing 100 new chairs. Based on this analysis, sustainable decommissioning actually avoids nine times more greenhouse gas emissions than WARM estimates.

The consequence: facility managers across the country are significantly underestimating their sustainability achievements, missing opportunities to demonstrate leadership and build stronger ESG cases.

The Facility Manager's Dilemma

Facility managers sit at the intersection of space planning, sustainability, and cost control. Today, this role is more challenging than ever.

The pandemic left organizations with a large surplus of furniture. As employees increasingly return to the office, companies are reconfiguring spaces for hybrid work, adding shared workstations and collaboration areas. This focus on hybrid employees has led to a large amount of idle furniture. Additionally, in many cases, ESG and sustainability reporting is no longer optional; boards, investors, and regulators all demand verified data. More importantly, budget constraints force facility managers to make the most of decommissioning funds, even though they often lack sufficient time to keep up with evolving environmental metrics.

WARM has limited applicability. This EPA tool is designed to measure the climate benefits of recycling and landfill diversion, not for commercial furniture.

What the Data Reveals

The Bard College research team used life cycle assessment (LCA) methodology to analyze 14 common office furniture items, and the results were striking. WARM captures only 6% to 28% of the actual emissions avoided when furniture is reused.

For facility managers, these numbers are clear. Take a task chair, for example, whose landfill impact is 6.33 kilograms of carbon dioxide equivalent (CO2e). But by reusing this chair—and avoiding the manufacture of a new one—you actually save 64.80 kg CO2e, a tenfold difference.

The main challenge in revising emission calculations and reporting methods is the lack of data. Apart from manufacturer Humanscale, few manufacturers have publicly available LCA data. Even when available, the data is often buried in 400-page reports. Inconsistent reporting standards also make like-for-like comparisons difficult.

Actions Facility Managers Can Take

This is a missed opportunity for facility managers to demonstrate value. If you are missing 90% of the climate benefits, you lose leverage for gaining support.

The good news is that facility managers do not need to wait for federal tools to be updated. In the short term, when reporting, request environmental product declarations (EPDs) and LCAs from furniture manufacturers for new purchases, and push suppliers for greater transparency. When working with suppliers, recyclers, or decommissioning partners, require them to use consistent definitions, such as distinguishing between "reuse" and "recycling," so your ESG reports compare consistent metrics. Leverage new digital tools, including AI-based tracking systems, which can help document which items are diverted, where they go, and calculate avoided emissions.

Finally, share community impact, including what was donated, who received it, and how it was used. Donated furniture often benefits schools, nonprofits, and transitional housing. A few desks may be insignificant to a company renovating its space, but for a cash-strapped school district, they can make a difference. Adding the narrative of social benefits humanizes the results and strengthens the story.

By adopting life cycle-based greenhouse gas measurement methods, supplementing WARM estimates, and prioritizing items most often diverted from landfills, facility managers can have a strong voice in shaping these standards, just as they once drove the adoption of LEED and green building certification.
