As the world is slowly working towards net-zero emissions, carbon removal has become a critical component of climate strategies. Unlike traditional carbon offsets, carbon removal projects actively extract carbon from the atmosphere and store it durably. Puro.earth certifies carbon removal projects that deliver measurable, durable, and scalable carbon removal.
This distinction is critical for addressing historical emissions and achieving true net-zero goals. However, not all carbon removal methods are equal. The market is flooded with varying claims of effectiveness, durability, and scalability, making it essential for businesses to focus on high-integrity, verified solutions.
Puro addresses this challenge by certifying projects that meet strict criteria for durability, measurability, and additionality. Through its CO₂ Removal Certificate (CORC) standard, Puro.earth ensures that every ton of CO₂ removed is real, permanent, and verifiable. For businesses committed to making a tangible climate impact, Puro.earth provides a trusted platform to invest in scalable, science-backed carbon removal solutions.
What Is a Carbon Removal Credit?
A carbon removal credit represents the permanent removal of one metric ton of CO₂ from the atmosphere. Unlike traditional carbon offsets, which focus on avoiding emissions, carbon removal credits ensure that CO₂ is actively captured and stored for the long term.
This approach is essential for addressing historical emissions and achieving true net-zero goals. Carbon removal methods include biochar, enhanced weathering, and direct air capture (DAC), each offering unique benefits for climate action.
What Is Puro.earth?
Puro.earth is the world’s first B2B marketplace dedicated exclusively to carbon removal. It certifies and trades CO₂ Removal Certificates (CORCs), where each CORC represents one metric ton of CO₂ permanently removed from the atmosphere.
Puro.earth ensures that all projects meet strict criteria for durability, measurability, and additionality. The platform connects businesses with high-quality carbon removal projects, enabling them to invest in real climate solutions.
What Makes a Carbon Removal Credit High Quality?
Not all carbon removal credits are created equal. High-quality credits must meet several key criteria:
Durability: The CO₂ must be stored for centuries or longer, ensuring that the removal is permanent.
Measurability: The amount of CO₂ removed must be accurately quantified and verified.
Additionality: The removal must go beyond what would have happened under business-as-usual conditions.
Transparency: Projects must provide clear, accessible data on their methods, impacts, and verification processes.
Puro.earth’s CORC standard ensures that all certified projects meet these criteria, providing confidence for buyers.

How to Buy Carbon Removal Credits from Puro.earth
To invest in carbon removal credits, start by defining your goals. Determine whether your focus is on durability, scalability, co-benefits, or cost-effectiveness. Puro.earth provides a variety of carbon removal methods, ranging from nature-based solutions like biochar to advanced technologies such as direct air capture (DAC). This diversity allows you to select the approach that best aligns with your organization’s sustainability strategy and climate objectives.
Once your goals are clear, you can purchase CO₂ Removal Certificates (CORCs) directly through suppliers like Regreener . For organizations looking to make larger investments, custom contracts are available directly with project developers, ensuring flexibility and tailored solutions.
After purchasing, the final step is to retire the CORCs in your company’s name. This ensures that the credits are permanently associated with your organization and cannot be resold. Highlight your investment in sustainability reports and use Puro.earth’s impact tracking tools to demonstrate your progress toward achieving net-zero emissions. This not only enhances your ESG credibility but also showcases your commitment to real climate action.
Risks and Considerations
When investing in carbon removal projects, it is important to consider several risks and factors to ensure the integrity and effectiveness of your investment.
Durability is a key consideration, as not all carbon removal methods offer the same level of permanence. For example, biochar and mineralization can store CO₂ for centuries to millennia, while some nature-based solutions may require ongoing monitoring to ensure that the carbon remains sequestered. Prioritizing methods with proven long-term storage, such as direct air capture or enhanced weathering, can help mitigate this risk.
Scalability is another important factor. Some carbon removal technologies, like direct air capture, are capital-intensive but have the potential for massive scaling in the future. Others, such as biochar, are lower-cost and can be deployed immediately. Balancing your portfolio between immediately deployable solutions and high-potential technologies can help you achieve both short-term and long-term climate goals.
Cost is also a significant consideration. Carbon removal credits are generally more expensive than traditional avoidance offsets, reflecting their greater climate impact. Prices can range from $50 to $600 per metric ton of CO₂, depending on the method. While the higher cost may be a barrier for some, it is important to recognize that this investment delivers real, measurable climate benefits. Early adoption of these technologies can also help drive down future costs as they become more widespread.
Additionality and Measurement are critical to ensuring that your investment delivers real impact. It is essential to verify that the projects you support go beyond business-as-usual practices and that their CO₂ removal is accurately measured and reported. Puro.earth’s CORC standard guarantees both additionality and precise measurement, providing confidence in the integrity of your credits.
Red Flags to Avoid:
Projects that lack third-party certification.
Methods with unproven durability or unclear storage mechanisms.
Projects that do not provide transparent data on their removal and storage processes.
Claims of scalability that are not backed by evidence or credible plans.
By carefully considering these risks and factors, you can make informed decisions that align with your sustainability goals and contribute to meaningful climate action.
