For decades, the voluntary carbon market has operated under a veil of ambiguity. Corporate sustainability officers, tasked with achieving ambitious net-zero targets, have long grappled with a fundamental question: should they invest in carbon removal credits—projects that physically pull CO2 from the atmosphere—or focus on emission reduction credits, which prevent carbon from being released in the first place?
The confusion has been exacerbated by shifting standards from global bodies, leaving many organizations paralyzed by the fear of choosing the “wrong” path. However, as the climate crisis intensifies and carbon markets mature, the binary distinction between these two strategies is being replaced by a more nuanced, portfolio-based approach.
The Evolution of Corporate Climate Strategy: A Chronology of Confusion
To understand the current state of the carbon market, one must look at how the guidance has shifted over the last decade. Historically, the discourse was dominated by a preference for "removals" as the gold standard for net-zero.
- The Early Years (2015–2020): Following the Paris Agreement, companies began setting aggressive climate targets. During this period, the emphasis was heavily placed on direct mitigation, but the role of "offsets" remained loosely defined.
- The Rise of the SBTi (2021–2023): The Science Based Targets initiative (SBTi) emerged as the primary arbiter of corporate climate ambition. Its initial Corporate Net-Zero Standard emphasized deep decarbonization and prioritized removals for neutralizing residual emissions. This created a market bias where companies felt that purchasing anything other than a "removal" credit was an inferior or non-compliant action.
- The Oxford Principles (2022): Conversely, the Oxford Offsetting Principles introduced a more pragmatic view, advocating for a "dynamic portfolio." This approach encouraged companies to support reduction credits early on, shifting toward removals as the technology matures and the target date approaches.
- The Convergence (2024–Present): In a significant pivot, the SBTi revised its guidance, now acknowledging that reduction credits play a legitimate role in managing a company’s responsibility for ongoing emissions in the near term. This shift has finally bridged the gap between the rigid "removals-only" mindset and the "dynamic portfolio" approach, providing companies with a clear mandate to diversify.
The "Bathtub" Fallacy: Dispelling Common Myths
A persistent narrative in the corporate world is that removal credits are inherently "more beneficial" to the atmosphere than reduction credits. Experts often use the "bathtub" analogy: emissions are the water filling the tub, while removals are the drain. If the tub is overflowing, the logic goes, we must open the drain.
However, this analogy masks a sobering reality: the tap is currently running 20 times faster than the drain. The world emits approximately 42 billion metric tons of CO2 annually, while current global removal capacity—largely driven by forest-based projects—is only about 2 billion metric tons.
Myth 1: Removals are inherently superior to reductions
There is a pervasive belief that a removal credit is a higher-quality product than a reduction credit. Data from industry leaders like Calyx Global, which has rated over 1,000 carbon projects, suggests otherwise. Integrity is not a label; it is a function of project design, monitoring, and verification. There are "hollow" removal projects that offer little climate benefit, just as there are high-impact reduction projects that provide immediate, verifiable climate dividends.

Myth 2: Nature-based removals are the only path
While tree planting is a popular choice for corporate portfolios, it is often misunderstood. Many reforestation credits are sourced from monoculture timber plantations, which are designed for harvest cycles rather than long-term carbon sequestration. In contrast, reduction projects—such as the capture and destruction of potent refrigerant gases or methane abatement in landfills—can deliver immediate, high-impact results that are far more effective at cooling the planet in the short term.
The Critical Case for Scaling Carbon Removal
Despite the importance of "turning off the tap," there are compelling reasons why corporations must invest in removal capacity. As we look toward mid-century targets, the math is inescapable: even with the most aggressive decarbonization efforts, there will be "hard-to-abate" residual emissions that can only be balanced by removals.
Closing the "Green Premium" Gap
Novel removal technologies—such as Direct Air Capture (DAC) and bio-energy with carbon capture and storage (BECCS)—are currently prohibitively expensive. Bill Gates has famously noted that these "green premiums" must be reduced by approximately 95% to make these technologies viable at scale. By purchasing these early-stage credits, corporations are not just buying carbon offsets; they are acting as "first-movers" who provide the necessary capital to drive innovation, lower costs, and build the infrastructure the world will desperately need by 2050.
The Ecosystem Services of Nature-Based Solutions
Nature remains the most efficient carbon-removal engine on the planet. Beyond sequestering carbon, intact ecosystems provide vital services: water filtration, flood mitigation, and biodiversity protection. In many cases, preventing the destruction of an existing forest (a reduction/avoidance activity) is far more impactful than planting a new one. The preservation of "irrecoverable carbon" in peatlands and old-growth forests serves as a critical buffer against climate feedback loops.
Official Guidance: How to Build a Modern Portfolio
The consensus among climate experts, including those from the SBTi and the Integrity Council for Voluntary Carbon Credits (ICVCM), is that companies should move away from the "either/or" mindset. A robust climate strategy is built on a portfolio of actions.
1. The Principle of "Common but Differentiated Responsibility"
Just as nations have different capacities to act, so do corporations. A highly profitable, tech-forward firm may have the financial latitude to invest in a portfolio dominated by high-cost, novel removals. A smaller or lower-margin firm might focus on high-quality, cost-effective reduction credits. The goal is not to force uniformity, but to ensure that every organization is contributing according to its capacity.

2. Prioritize Quality Over Category
The most important metric is the integrity of the credit. A company should ask:
- Additionality: Would this project have happened without my funding?
- Permanence: How long will this carbon stay out of the atmosphere?
- Leakage: Does this project displace emissions to another region?
- Measurement: Is there robust, third-party verification of the carbon impact?
3. The "Near-Term vs. Long-Term" Balancing Act
For the remainder of the 2020s, companies should prioritize high-quality reduction credits to address their current emissions footprint. As the decade progresses and the global infrastructure for removal scales, corporations should gradually increase the share of removals in their portfolio. This transition ensures that the company is effectively mitigating its impact today while supporting the essential technologies of tomorrow.
The Road Ahead: Beyond Carbon Offsetting
The future of corporate climate action lies in moving beyond the "carbon neutral" marketing badge. Instead, it is about aligning corporate strategy with the physical reality of the climate crisis.
There is no such thing as a "second-class" climate action. The only meaningful divide in the carbon market is between those companies that actively engage in high-integrity projects and those that remain on the sidelines. By choosing a balanced portfolio, investing in both the immediate impact of reduction and the long-term potential of removals, companies can transform from passive participants in the market to active architects of a net-zero future.
In conclusion, the decision to invest in removals or reductions is not a binary choice but a strategic one. It requires a commitment to transparency, a rigorous focus on quality, and a willingness to invest in the technologies that will define the next fifty years of global climate policy. The "bathtub" is filling, and the world cannot afford to wait for a perfect solution before taking action.
