Aviation Services

Conversio provides you with measurement, reporting and verification services. Find the services you need for meeting CORSIA compliance.

Conversio is a Brisbane-based carbon accounting and reporting consultancy. We support you by providing carbon footprinting, reporting and verification (MRV) services for your aircraft’s participation under CORSIA.

What is CORSIA?

Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is a global market-based measure designed to support the international aviation community’s efforts to stabilise international aviation CO2 emissions and achieve carbon neutral growth from 2020 onwards (CNG2020). CO2 emissions will be offset through the acquisition and surrender of greenhouse gas (GHG) emission units from the carbon market by aircraft operators.

Unlock cost-saving opportunities with a structured approach to carbon and energy management. We help you deal with rising energy prices, climate policy and compliance obligations by assessing energy use and carbon emissions. We provide a bespoke carbon and energy strategy for your business so you can reach your sustainability goals.

How does CORSIA work?

CORSIA is a market-based measure to address and offset annual increases in GHG emissions above 2020 levels from international operations. From January 2019, aircraft operators are required to measure and report their GHG emissions from international flights to their relevant state Civil Aviation Authority, irrespective of the aircraft operators’ location. GHG emissions reported in 2019 and 2020 will form the baseline for determining carbon neutral growth from 2020.
There are two phases to CORSIA:

  • Pilot phase (2021-2023) and first phase (2024-2026): Participation of states that are participating in CORSIA voluntarily; and
  • Second phase (2027-2035): Participation of all states unless exempted or volunteered to participate (emitting less than 10,000 tonnes CO2 per year, Emissions from aircraft with less than 5,700kg MTOM, humanitarian, medical and firefighting operations, Least Developed Countries, Small Island Developing States and Landlocked Developing Countries).

CORSIA covers the route between states participating in the scheme. International flights will be covered by CORSIA if both states connecting the route are participating in the scheme; if one or both states connecting the route are not participating in the scheme, the international flight is not be covered by CORSIA.

Emissions Monitoring Plan

Aircraft operators must develop an Emissions Monitoring Plan (EMP) which outlines

  • the operator’s monitoring of fuel burn and associated CO2 emissions for each flight, including method for calculating CO2 emissions and how CO2 emissions data will be managed; and
  • calculation of CO2 emissions based on fuel burn.

The EMP must be submitted to the relevant Civil Aviation Authority for consultation and approval.

Reporting

Annual reporting of CO2 emissions data provides the basis to calculate the total emissions and annual offsetting requirements of individual aircraft operators. ICAO recommends the first EMP to be completed by the end of 2018. The verified EMP must be submitted to the relevant Civil Aviation Authority by 28 February 2019.

Verification

Verification on emissions data is important to ensure the accuracy, relevance and consistency of data and to identify any material errors in the aircraft operator’s annual Emissions Report. CORSIA has a three-step verification approach:

  • An internal pre-verification by the aircraft operator;
  • Third-party verification before reporting to the state Civil Aviation Authority; and
  • An order of magnitude review by the state Civil Aviation Authority.

Verification will be conducted in accordance with ISO 14064 – Part 3.

Carbon offsetting requirements

Carbon offsetting requirements will be determined by multiplying the aircraft operator’s annual emissions times the growth factor. Under CORSIA, obligations will be divided between sectoral approach (overall growth in GHG emissions in the sector divided between operators) and the individual approach (each operator’s own individual growth), gradually moving from sectoral to individual:

  • 2021-2029: 100% sectoral approach;
  • 2030-2032: Maximum 80% sectoral approach + at least 20% individual approach; and
  • 2033-2035: Maximum 30% sectoral approach + at least 70% individual approach.

How Conversio supports you

Together with our partner Waypoint Aviation we help you prepare for the scheme’s requirements commencing in January 2019, support you in developing and implementing the EMP and assist in estimating GHG emissions from your international operations. Conversio can also assist in the internal pre-verification process, as well as provide external third-party verification services, and provide guidance on eligible carbon offset units and the use of the CORSIA CO2 Estimation and Reporting Tool (CERT).
