What you need to know
International aviation is responsible for approximately 1.3% of global carbon dioxide emissions, and aviation emissions are forecast to grow in the coming years. Projected annual improvements in aircraft fuel efficiency of around 1 to 2% are surpassed by forecast traffic growth of around 5% each year.
Although domestic aviation emissions are covered by the Paris Agreement, it does not explicitly mention international aviation emissions. The International Civil Aviation Organization (ICAO) is responsible for regulating international aviation activity. In 2013, ICAO agreed on a global goal to achieve carbon neutral growth in the international aviation sector from 2020, and in 2016, it agreed to introduce the CORSIA, a global market-based measure for reducing and offsetting carbon emissions in the international aviation sector.
In September 2016, the Government agreed New Zealand would participate in CORSIA when it comes into effect on 1 January 2021. In 2019, the Government reconfirmed this decision, agreeing that CORSIA would be implemented in New Zealand via the Civil Aviation Bill.
The work to date
41st International Civil Aviation Organisation General Assembly
New Zealand attended the 41st International Civil Aviation Organisation (ICAO) General Assembly in September 2022.
Participation in CORSIA reconfirmed
The Government reconfirmed the decision to participate in CORSIA from 2021, and agreed to implement it through the Civil Aviation Bill. Participating in CORSIA will strongly support the Government’s climate change priorities as it aims to address any annual increase in total carbon dioxide emissions from international civil aviation above 2020 levels.
Decision to join CORSIA confirmed
The Government agreed that New Zealand would participate in CORSIA when it comes into effect in 2021.
