Carbon Credits are also called Carbon Removal Certificates or CRU (Carbon Removal Units). These CRUs result from projects that are certified CO2-reducing. In the past, Carbon Credits mainly focused on certifying avoidable emissions. Nowadays the general opinion is that that is not enough. To achieve the climate goals, CO2 must also be removed from the atmosphere. Projects that contribute to this include Direct Air Capture, Biochar or Carbon Farming. These projects generate Carbon Removal Certificates or Carbon Removal Units.
