Carbon neutrality is a must, with extensive sustainability plans closely incorporated in Siam Seaplane Sustainability’s strategic planning. We take pride in building our experience with the concept of “sustainable by design” — executed in three phases, from carbon compensation to bio-fuels and eventually full electrification.

Phase 1


The carbon footprint we generate is measured through industry-standard methodologies. By default we compensate for the carbon emissions of every flight minute and every flying guest. Further supporting local development, we run compensation programs in partnership with local initiatives such as turtle conservation & coral planting of Koh Talu, and selected foundations across Thailand.

Phase 2

Aviation Fuels

We will use sustainable aviation fuels (SAF) as soon as available in the region, with the aim to become pioneers in Asia using SAF.

  1. Bio-fuel (from used oils & biomass)
  2. E-fuel (from hydrogen), which can reduce greenhouse gas emissions by up to 80%

Implementation goal — within 2 years.

Phase 3


We will participate in the R&D for electric engine conversion (full retro-fitting), for example with the world-class technology leader MagniX (Seattle, USA). Two seaplane operators, in Australia and the USA, are currently commercially testing full electric seaplanes.

Implementation goal — within 5 years.

How do we calculate our emissions?

We follow standard methodologies for calculating our CO2 emissions. We always calculate, and compensate for, the entire aircraft, regardless of how many guests charter the plane. Aircraft emissions are an exact multiple of fuel consumption, and the multiplier depend on the fuel type used. The fuel consumption is converted into mass, which in turn is multiplied by the relevant emission factor (more info).

We display the estimated emissions on all of our advertised routes and flights.

How do we determine emission savings compared to other transportation methods?

If our route is from airport to airport, it is a direct comparison between our aircraft's emissions and the emissions of a typical conventional aircraft for such a route, calculated by pax and multiplied by 10 (to match our aircraft guests' capacity).

If our route is from airport to water landing site (or vice versa), we factor in the emissions generated by all modes of transportation required for such a route if not using an amphibious aircraft, for example including a conventional aircraft, a car and a boat or ferry ride. For this, we use standard emission calculators (such as here and here).
