Japan Aviation Emissions: Haneda and Narita Airports Among Top Asia-Pacific Polluters

A new report from ODI Global and Transport & Environment reveals that Japan's aviation sector is the fourth largest emitter globally. Tokyo's Haneda and Narita airports combined produce nearly 20 million tonnes of CO2, highlighting a significant gap in the country's 2050 carbon neutrality goals. Only 2.3% of airports worldwide have Scope 3 net-zero plans, despite these emissions making up over 90% of an airport's total climate impact. Experts are calling for a shift toward e-fuels and more transparent measurement, reporting, and verification (MRV) frameworks to hold the industry accountable.

The gap between the 2050 goal and the current lack of Scope 3 plans is huge. Without a strict MRV framework, these net zero roadmaps are just paperwork. We need to see actual procurement rules for e-fuels before this moves the needle.

Good point on the e-fuels. My question is where the power for those synthetic fuels is coming from. If they are not using additional renewable capacity, they are just shifting the emissions to the grid.

Asia-Pacific now accounts for 32% of global aviation CO2. That is a massive chunk. The report shows that most airports are ignoring Scope 3 emissions because they are harder to track, but that is where the actual problem lives.

Exactly. It is easy to claim a green terminal building when the planes taking off are still burning standard kerosene. The focus needs to be on the fuel and the flight volume, not the airport architecture.
