Puro.earth: Enabling carbon sequestration
On the Puro Registry you can view CO2 Removal Certificates, or CORCs, that have been retired. CORCs are retired when a beneficiary makes a net zero or carbon neutrality claim that is supported by the CORCs’ carbon sequestration properties.
Carbon sequestration refers to CO2 that has been captured from the atmosphere and stored in a durable carbon sink. In contrast to traditional carbon offsets that focus on reduced emissions, CORCs exclusively entail high-quality carbon removals, also known as CDR – Carbon Dioxide Removal.
Puro.earth developed the first carbon sequestration methodologies for biochar, bio-based and carbonated construction materials, soil amendments and geologically stored carbon that can be captured through various means, including Direct Air Capture (DAC). When evaluating carbon sequestration projects, we consider how carbon is captured, stabilized and stored in a long-term carbon sink.
Our methodologies are science-based and use a lifecycle analysis (LCA) for reporting emissions and stored carbon, or CO2-equivalents. Removed carbon is the sequestered carbon minus the emission that is calculated as part of the product or processes’ LCA. In other words, CORCs only consider net-negate emissions from Negative Emissions Technologies (NET). The verification of sequestered carbon is done annually by an independent auditor, using laboratory analyses and measurements to ensure that net negativity claims comply with the Puro Standard’ science-based methodologies.
The data is updated on a daily basis. Data prior to January 2022 is made available when consent is received from both parties. The Beneficiary can request a delay in publishing, no longer than 12 months.
