Learn how direct air capture and carbon offsets differ, which strategy fits your business, and how to evaluate both options for meaningful climate action.
June 26, 2026
If you're a facility manager or business owner thinking about your carbon footprint, you've likely encountered two terms that sound similar but operate in fundamentally different ways: direct air capture (DAC) and carbon offsets. Understanding the distinction between them isn't just academic—it directly affects how you spend your climate budget and what impact you actually achieve.
Carbon offsets work by funding emissions reductions or removals somewhere else in the world or supply chain. When you purchase a carbon offset, you're typically paying for a project—maybe renewable energy installation, forest conservation, or methane capture from agricultural operations—that reduces or prevents greenhouse gases that would otherwise enter the atmosphere. The theory is that a ton of CO2 prevented in one location offsets a ton of emissions your business produces elsewhere. Direct air capture, by contrast, is a physical technology that removes carbon dioxide directly from the air using machines, then either stores it permanently underground or uses it in products. Nothing is offset; the CO2 is simply taken out of circulation.
For SMBs, this distinction matters enormously. An offset is a financial transaction based on trust in a third party's measurement and verification. DAC is a tangible capital investment in equipment and infrastructure. One relies on accounting and certification; the other relies on engineering and chemistry.
Carbon offsets have been the dominant climate strategy for businesses over the past two decades because they're relatively affordable and straightforward. When you buy an offset, you're purchasing credits—typically in units of one metric ton of CO2 equivalent avoided or removed. Prices vary widely, from as low as $5 to $10 per ton for older, less-certain projects to $15 to $25 per ton for higher-quality, verified offsets. For a small manufacturing facility producing 500 tons of CO2 annually, offsetting all of it might cost between $2,500 and $12,500 per year.
The appeal is obvious: you can address your carbon footprint without major operational changes. You don't need to retrofit your building, replace equipment, or redesign your supply chain. You simply purchase credits from a broker or directly from project developers, and those credits represent real-world emissions reductions somewhere.
However, the offset market has significant credibility challenges. Not all offsets are created equal. Some projects suffer from additionality problems—meaning the emissions reduction would have happened anyway without your payment. Others face permanence questions: if you fund forest conservation, what happens if that forest burns down twenty years later? Some offset protocols are more rigorous than others. The most trusted certifications come from standards like the Gold Standard, Verra (formerly VCS), or the American Carbon Registry, which apply stricter methodologies and verification requirements. These higher-quality offsets typically cost 40 to 60 percent more than lower-grade alternatives.
For SMBs, the practical challenge is due diligence. Evaluating an offset's actual integrity requires understanding methodologies that can be dense and technical. Many small business owners end up relying on brokers' representations without fully vetting the underlying projects, which creates risk if those projects later prove problematic.
Direct air capture sounds like science fiction, but it's increasingly real. DAC facilities use large fans to pull ambient air through filters or solvents that bind to CO2 molecules. Once concentrated, the CO2 is either compressed and injected deep underground for permanent geological storage—this is called DAC-with-storage or carbon removal—or sold to industrial users for beverages, chemicals, or enhanced oil recovery.
As of early 2024, DAC projects are still predominantly in the demonstration and early commercial stages. There are only a handful of operational facilities globally. The largest is Climeworks' Mammoth facility in Iceland, which began operations in 2024 with the capacity to remove 36,000 tons of CO2 annually. This gives you a sense of scale: removing what a small manufacturing business produces in 70 years takes a facility the size of multiple warehouses operating continuously.
The cost of direct air capture is significantly higher than offsets. Current removal costs range from $150 to $300 per ton, with projections that scaling could eventually bring that down to $100 to $150 per ton by 2030. For that same 500-ton facility, offsetting through DAC would cost $75,000 to $150,000 annually—a vastly different financial picture than offset purchases.
So why would an SMB consider DAC at all? The answer is permanence and certainty. When CO2 is captured and stored in geological formations like basalt, it's locked away for hundreds of thousands of years. There's no additionality problem, no verification ambiguity, no project failure risk. The removal is direct, measurable, and final.
Both strategies can be legitimate parts of a climate commitment, but they serve different purposes. Carbon offsets are better suited for businesses that want to address their carbon footprint cost-effectively and quickly while making operational improvements. If you're planning an HVAC upgrade that will reduce energy consumption by 30 percent, offsets make sense for the emissions you can't eliminate through efficiency. Offsets also remain the only practical option for some categories of emissions, particularly hard-to-abate sectors like air travel or certain industrial processes.
Direct air capture makes more sense for businesses with specific strategic objectives: demonstrating technological leadership, addressing legacy emissions, or making permanent removal commitments that matter for brand positioning. DAC also becomes more economically viable when you have access to co-location benefits. For example, if you operate a facility near a geothermal energy source, like Climeworks does in Iceland, the energy costs for running DAC equipment drop dramatically. Some DAC projects are also beginning to qualify for federal tax credits under the Inflation Reduction Act—up to $180 per ton for projects that store captured CO2 permanently.
For most SMBs today, the practical reality is that offsets remain the more accessible option. But this doesn't mean DAC should be ignored. As the technology scales and costs fall—most experts predict a 40 to 50 percent cost reduction by 2030—SMBs may increasingly incorporate DAC as part of broader climate strategies, perhaps dedicating a portion of their climate budget to permanent removal while using offsets for emissions reductions.
Your decision should start with a clear inventory of your emissions across Scope 1 (direct operations), Scope 2 (purchased energy), and Scope 3 (supply chain and value chain). Many SMBs find that 50 to 70 percent of their emissions can be addressed through operational improvements: energy efficiency, renewable energy procurement, supply chain optimization, and waste reduction. This should be your priority because you're actually reducing your footprint, not transferring responsibility elsewhere.
Once you've maximized emissions reduction, offsets are typically the logical next step for any remaining unavoidable emissions. This is where most SMBs should focus. Choose verified offsets from reputable programs, prioritize removal-based offsets over reduction-based ones if budget allows, and document your choices transparently for stakeholders.
Direct air capture might be worth exploring if your business wants to make a stronger climate commitment, has marketing value in demonstrating permanent removal, or has capital available for longer-term climate investments. As the technology matures and costs decline, DAC will likely transition from a niche option to a mainstream strategy.
The most important step is starting somewhere. Whether you choose offsets, DAC, or most likely both, beginning to measure and address your emissions signals that climate action is integral to your business strategy. To understand which specific incentives and programs your facility qualifies for, consider running a diagnostic assessment tailored to your operations and regional context—this can reveal tax credits, grant opportunities, and strategic pathways you might otherwise miss.
