We clarify the strategy we used to establish CORSIA-eligible initiatives world wide, based mostly on the standards of the pilot section 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 so as to obtain the CORSIA eligible initiatives checklist 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 additionally for presidency organizations, firms wishing to offset enterprise journey, mission builders wishing to qualify for CORSIA, and others. AlliedOffset’s Premium Plus Dashboard has the info obligatory to seek out eligible initiatives.
We created this checklist by growing a way of filtering initiatives to go well with each clause throughout the CORSIA standards.
Within the present section, CORSIA solely accepts items from eight registries: ACR, ART, CCER, CDM, CAR, GCC, GSR, and VCS. Accredited eligible emissions reductions should have been issued to actions that began their first crediting interval from 1st of January 2016 by 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 information on these eight registries then filter them by first crediting date accordingly, offering us with a base information set. The place registries don’t report crediting durations, we used first classic date as a proxy.
Subsequent, we filtered the bottom information based on the next mission traits: nation, methodology, sector, annual emissions reductions, verification and validation standing, and reported sustainable improvement contributions.
On this section, 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: Initiatives 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 improvement 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: Initiatives involving nuclear vitality, 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 items 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 collaborating within the utility for CCBs or SD Vista Commonplace; 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 supplied us with the ultimate set of CORSIA eligible initiatives throughout the present section of the Pilot Part. As for Part 1, which begins in 2023, ICAO is searching for to incorporate extra methodologies and extra registries. AlliedOffsets replace the checklist accordingly because the initiatives from new registries are made eligible.
