A recent ICAO ruling on Zimbabwe's carbon credits has exposed a gap between the Paris Agreement's sovereign carbon pathway and CORSIA's rules. Credits that moved through a national registry were ruled ineligible for the compliance market, even though they had full government authorization and corresponding adjustments. The result is a $14 per tonne price gap between sovereign and private standard credits, hitting African countries that build out state-controlled carbon frameworks. For Tanzania, which has one of the largest forest carbon pipelines in Africa and whose president endorsed the AUDA-NEPAD principles on carbon equity in February 2026, the ruling is a direct challenge. The country's REDD+ program and NDC targets depend on revenue from credits the host government controls. Analysts suggest mirroring private registries as a workaround, but that keeps control outside the country. The article argues Tanzania should use its standing to push for rule alignment at the ICAO Council session in June 2026. Without a coordinated African position, the gap between continental principles and international rules will keep sovereign carbon assets priced at a discount.
