THE SUSTAINABILITY RENAISSANCE
We help airlines, aircraft operators, and emissions unit suppliers navigate ICAO's Carbon Offsetting and Reduction Scheme for International Aviation — from monitoring plans to verified emissions reports to eligible offset sourcing.
ADVISORY & CONSULTING
CORSIA is the first global market-based measure adopted for any single industry sector — requiring international aircraft operators to monitor, report, and offset CO2 emissions above their baseline. What began as a voluntary pilot is now on a fixed path to mandatory participation for most ICAO member states from 2027.
As of 2026, 130 states participate in CORSIA offsetting, and the scheme's baseline has been tightened to 85% of 2019 emissions from 2024 onward — meaning offsetting obligations are only set to grow through to 2035. Operators without a monitoring plan, verified emissions data, and a credit-sourcing strategy in place risk both compliance exposure and cost surprises at each three-year settlement.
Compliance Kart's CORSIA Advisory practice supports operators end-to-end — and, on the supply side, helps project developers align nature-based and removal credits with ICAO's Emissions Unit Criteria for CORSIA eligibility.

THE ICAO FRAMEWORK, PHASE BY PHASE
CORSIA's obligations tighten in a fixed, published sequence. We plan our advisory against the same timeline ICAO uses to set your offsetting requirement.
Baseline: 2019 emissions. Participation limited to volunteering states.
WHAT IT MEANT
No offsetting requirement accrued — the Sectoral Growth Factor was set to zero for 2021, 2022 and 2023.
Baseline: 85% of 2019 emissions. 126+ states participating, rising to 130 by 2026.
WHAT IT MEANS
Real offsetting requirements begin. Operators must settle Compliance Period 2 (2024–26) obligations at cycle end.
Applies to all ICAO Contracting States by default, based on 2018 RTK share; certain exemptions apply.
WHAT IT MEANS
Offsetting requirement calculations shift progressively toward individual operator growth. Covers Compliance Periods 3–5.

WHY COMPLIANCE KART
Our CORSIA advisory is built on the same digital MRV discipline we apply to our own carbon removal projects — structured, auditable, and built to survive scrutiny, not just describe intent.
01
We advise operators on meeting their offsetting requirement, and help project developers meet the same ICAO eligibility bar for supply — a full-circle view few advisors offer.
02
The same emissions monitoring rigor we apply to our own biochar and AFOLU carbon projects underpins our CORSIA advisory work.
03
Our PCAF Regional Accredited status brings financial-grade carbon accounting rigor to aviation emissions reporting.
We'll map your monitoring plan, baseline exposure, and offsetting requirement against the current compliance period — before your verifier does.
