Carbon Index Spotlight on Airlines, Aircraft and Lessors - June 2022

IBA has published its latest aviation Carbon Index in partnership with KPMG. Our latest analysis for June 2022 includes a spotlight on the efficiency of lessors in the APAC region.

Summary analysis

Aviation carbon emissions intelligence from IBA NetZero has revealed that CO2 emissions from commercial aviation averaged 143.1 grams of CO2 per-seat-per mile in June 2022, with overall carbon intensity per seat decreasing by 0.4%. This represents a 2.4% reduction in CO2 intensity per-seat per-mile year-on-year, another record low for the industry.



June 2022 saw additional international and domestic growth as summer got into full swing, with a 4% increase in global traffic month-on-month. Global flight volumes have increased across the board, except for the Latin American market, which saw a 3% reduction in flight volumes. The Asia Pacific region continues to grow, with an 11% increase in domestic and a 6% growth in international flights. Flight volumes have been steadily increasing in the North American domestic traffic market in the months leading up to June, however the market has stagnated somewhat compared to the previous months, bringing traffic growth broadly in line with the European and Asia domestic markets.


Surprisingly, the largest growth in flight volumes within Europe and CIS is being driven by Russian operators. S7 Airlines, Rossiya and Aeroflot have each seen a 30%, 12% and 27% increase in flight volumes respectively. This equates to an additional 7,000 flights, making up 18% of all the growth within the Europe & CIS region in June 2022.


Governments play a key role in promoting and developing carbon alternatives. Yet because of the international nature of aviation, scope for domestic action is more limited to the likes of airport initiatives and domestic flights. It needs greater international alignment. Only recently, IATA has called for governments to urgently put in place large-scale incentives to rapidly expand the use and production of sustainable aviation fuels (SAF). ICAO's 57th Conference of Directors General of Civil Aviation for Asia and Pacific Regions made several similar recommendations.


Industry-led examples can be seen in the recent announcement from Qantas and Airbus - announcing a AUD$200 million ($140m) five-year partnership to expedite the production of sustainable aviation fuels in Australia (by investing in local fuel and feedstock initiatives). The airline has also revealed “encouraging discussions” with the country's newly-elected federal government to support a transition of the aviation industry to low carbon fuels. But let's not kid ourselves - even if every planned SAF plant comes online as intended, there will remain a significant supply shortage, in turn driving a price delta between it and Jet-A1. Some in air finance will watch this dance from afar, others are actively exploring how they can profitably coinvest in scaling SAF production.

Aircraft efficiency spotlight

The global share of emissions in June 2022 did not change significantly, though we did observe a slight shift towards the Boeing 737-800, which saw an increase of 0.5%. The Boeing 777-300ER saw a decrease in monthly share of 0.3%.



Airline efficiency spotlight

French BEE remained at the top of our ranking of the most efficient airlines in June 2022, largely thanks to their fleet of high-density Airbus A350 aircraft. Sunwing Airlines re-enters the ranking this month with an all 737 family fleet of six Boeing 737 MAX 8 aircraft and five 737-800, six of which are owned by Air Lease Corporation and three by Aviation Capital Group all in high density 189 seat configuration.



Monthly spotlight: the most efficient lessors in the Asia Pacific region

This month, we shine our spotlight on aircraft lessors in the Asia Pacific region. We last reviewed these in December 2021.



  • SMBC Aviation Capital ranks as the most efficient lessor in the region on a per-seat per-mile basis. IBA Insight reveals the lessor manages around 430 aircraft, and that their overall CO2 efficiency per-seat per-mile has reduced by approximately 1 gram per month.

  • In our opinion, this has largely been driven by the Japanese lessor taking delivery of 8 Boeing 737 MAX and 5 Airbus A321-200neo aircraft. SMBC's fleet is comparatively young, with an average age of 6 years old compared to the industry average of 13.5 years. We anticipate the fleet age will continue to reduce thanks to SMBC's sizeable order book of almost 200 next generation narrowbodies.

  • Chinese lessor AVIC also performs well in our ranking, with an extremely diverse portfolio of aircraft. The most numerous in-service type is the Airbus A350-900, with 17 aircraft leased to Air China, Ethiopian Airlines, Turkish Airlines and Vietnam Airlines. IBA Insight reveals that AVIC's portfolio comprises of 56% narrowbody aircraft. 65% of these are A320 family aircraft (mostly neo) and 35% are of the 737 family. Whilst AVIC has 15 Comac C919 aircraft on order at present, we do not anticipate any meaningful change to their CO2 output in the near future.

  • Tokyo Century Corporation holds a portfolio exclusively comprising of narrowbody assets, which are 8.5 years old on average. Of the 70 aircraft within Tokyo Century Corporation's current fleet, only five aircraft are new generation Airbus A321-200neo aircraft. The remainder are of the 737 NG series and A320ceo family. IBA Insight shows no new aircraft orders as of June 2022, and we anticipate little change to their ranking unless more new generation aircraft are introduced to the portfolio.


IBA NetZero is the most advanced finance-focused carbon modelling tool currently available; we're leading the way. It's powered by IBA's proprietary fuel-burn intelligence which, when integrated with the Flights and Fleets module, can illustrate carbon emissions by any combination of: time period, airline, lessor, aircraft MSN and model, fleet, future portfolios, OEM, country, airport and route pair.
