RDC June 2026 Aviation Emissions Report: Mexico

Following our analysis of the United States in last month's report, this edition we look at Mexico’s aviation emissions.

Please note as this report is derived from scheduled flight data, emissions linked to the Gulf region may not fully reflect actual flying activity, especially in relation to flight cancellations.

Focus market on this month's report: Mexico

Key highlights

• Global passenger aviation emissions for June 2026 are estimated at 68 million tonnes of CO₂
• Year-to-date emissions reached 398 million tonnes of CO₂, slightly above 2025 levels (397 million tonnes) and below 2019 levels (401 million tonnes).

Mexico spotlight

While aviation emissions in Mexico remained slightly below both 2025 and pre-pandemic 2019 levels during June 2026, the country ranks among the world's largest aviation emissions markets.

Key observations include:

• Mexico generated 975,535 tonnes of CO₂ emissions during June 2026
• The country ranked as the 17th largest aviation emissions market globally in June and 18th largest on a year-to-date basis
• Volaris was the largest contributor to emissions over the last 12 months, generating 2.6 million tonnes of CO₂. At the same time, it achieved an emissions intensity of just 57.4g CO₂ per ASK, making it one of the most efficient major carriers in the market
• Mexico City International Airport is the country's largest source of aviation emissions, producing 3.71 million tonnes of CO₂ over the last 12 months. However, Tijuana International Airport recorded the lowest emissions intensity among Mexico's major airports, at 58.4g CO₂ per ASK
• Whilst below levels seen in Europe, approximately 51% of aviation emissions generated in Mexico year-to-date are covered by compliance programmes, reflecting significant participation in emissions management frameworks

CARE Index

The RDC CARE Index scores any air route, airline and aircraft combination between 0 (worst) and 10 (best) based on fuel burn, seat capacity and load factor, use of sustainable aviation fuel, participation in compliance programmes such as EU ETS, and whether the carrier offsets emissions. It's designed to give both consumers and industry a clear, comparable measure of airline sustainability.

Here are the highest-scoring carriers by region in June 2026:
