Partnership provides additional layer of transparency and choice for participants 26 Jul 2021 | The Asset AirCarbon Exchange (ACX), a Singapore-based digital exchange for trading environmental projects and carbon credits, has integrated the BeZero Carbon Ratings (BCR) onto its platform. The BCR, created by London-based climate solutions provider BeZero Carbon, assesses the carbon quality of different offset projects. The BCR provides an additional layer of assessment for carbon projects accredited by voluntary offset standards such as VCS, Gold Standard, ACR, CAR and Plan Vivo. Using a scale (from AAA+ to A), BeZero rates offsets by the probability that a credit achieves a tonne of carbon dioxide equivalent (CO2e) avoided or removed. An AAA+ rating represents a 90% or more chance that the credit truly equals a tonne of CO2e, while a rating of A represents a 30-40% chance.
