ICAO decides that most probably emissions units generated from mechanism established under the UNFCCC and the Paris Agreement will be eligible for use in CORSIA
The Council of the International Civil Aviation Organization (ICAO), the UN body responsible for global aviation, approved the Emissions Unit Eligibility Criteria (EUC) for Carbon Offsetting and Reduction Scheme for International Aviation, CORSIA. This means what offsets can be used under the new aviation pollutions scheme. And emissions units generated from mechanism established under the UNFCCC and the Paris Agreement most probably will be eligible for use in CORSIA (pending of final approval) among others.
About Carbon Offset Credit Integrity Assessment Criteria, there are a number of generally agreed principles that have been broadly applied across both regulatory and voluntary offset credit programs to address environmental and social integrity. These principles hold that offset credit programs should deliver credits that represent emissions reductions, avoidance, or sequestration that:
– Are additional.
-Are based on a realistic and credible baseline.
-Are quantified, monitored, reported, and verified.
– Have a clear and transparent chain of custody.
-Represent permanent emissions reductions.
-Assess and mitigate against potential increase in emissions elsewhere.
-Are only counted once towards a mitigation obligation.
-Do no net harm.
Also there are criteria for emissions unit programme design elements:
-Clear methodologies and protocols and their development process
-Offset credit issuance and retirement procedures
-Identification and tracking
-Legal nature and transfer of units
-Transparency and public participation provisions
-Sustainable development criteria
-Avoidance of double counting, issuance and claiming
