We clarify the tactic we used to establish CORSIA-eligible initiatives around the globe, based mostly on the standards of the pilot part 2021–2023, final up to date in November 2021.

Our earlier weblog on CORSIA launched the incorporation of CORSIA eligibility in our Premium Dashboard. This weblog will dive deeper into the steps we took with a view to obtain the CORSIA eligible initiatives record discovered on the AlliedOffsets Premium Dashboard.
Having a listing of CORSIA eligible initiatives is extraordinarily useful, not only for these within the airline trade, but in addition for presidency organizations, corporations wishing to offset enterprise journey, mission builders wishing to qualify for CORSIA, and others. AlliedOffset’s Premium Plus Dashboard has the information essential to seek out eligible initiatives.
We created this record by growing a way of filtering initiatives to swimsuit each clause throughout the CORSIA standards.
Within the present part, CORSIA solely accepts models from eight registries: ACR, ART, CCER, CDM, CAR, GCC, GSR, and VCS. Accepted eligible emissions reductions will need to have been issued to actions that began their first crediting interval from 1st of January 2016 by way of to the thirty first of December of both 2020 or 2022, relying on the registry. This implies our first steps had been to extract all mission knowledge on these eight registries then filter them by first crediting date accordingly, offering us with a base knowledge set. The place registries don’t report crediting intervals, we used first classic date as a proxy.
Subsequent, we filtered the bottom knowledge in keeping with the next mission traits: nation, methodology, sector, annual emissions reductions, verification and validation standing, and reported sustainable growth contributions.
On this part, we divided the bottom set into their respective registries then carried out the person registry audits by excluding:
- ACR: All California based mostly initiatives; ERTs issued to actions developed in REDD+ international locations and make the most of methodologies within the programme’s sectoral scope 3, however provided that they’re estimated to generate higher than 7,000 offsets yearly.
- ART: No exclusions.
- CCERs: Tasks with methodologies in forestry, agriculture, carbon seize, and administration of fluorinated gasses, fertilizer functions, N2O, HFC, SF6, and HCF22.
- CDM: Forestry sector.
- CAR: All California based mostly initiatives; initiatives with out reported sustainable growth contributions or co-benefits; forestry sector; CRTs issued to actions developed in REDD+ international locations and make the most of methodologies within the AFOLU classes, however provided that they’re estimated to generate higher than 7,000 offsets yearly. (Besides Mexico based mostly initiatives that make the most of the Reserve’s Mexico Forest Protocol.)
- GCC: Tasks involving nuclear power, HFC-23 abatement, REDD+ registered, forestry sector, and carbon seize and storage initiatives.
- GSR: Deliberate emissions reductions, microscale actions with out validation and verification, and models issued to actions developed in REDD+ international locations and make the most of methodologies within the AFOLU classes, however provided that they’re estimated to generate higher than 7,000 offsets yearly. (Besides initiatives that make the most of methodologies within the Soil Natural Carbon, Agriculture, and Livestock classes.)
- VCS: All California based mostly initiatives; actions with out or not participating within the software for CCBs or SD Vista Normal; VCUs issued to actions developed in REDD+ international locations and make the most of methodologies within the AFOLU classes, however provided that they’re estimated to generate higher than 7,000 offsets yearly. (Besides the next methodologies: VM0012, VM0017, VM0021, VM0022, VM0024, VM0026 (and VMD0040), VM0032, VM0033, VM0036, VM0041, VM0042.)
These filters then offered us with the ultimate set of CORSIA eligible initiatives throughout the present phase of the Pilot Part. As for Part 1, which begins in 2023, ICAO is looking for to incorporate extra methodologies and extra registries. AlliedOffsets replace the record accordingly because the initiatives from new registries are made eligible.
