Why we fly

On our Diamondo Earthrounding flight around the world, we link worldwide initiatives for sustainable aviation.

Initiatives on our route


Solar power plant replaces fossil energy

Dominican Republic

Installing the largest solar power plant in the Caribbean, this project of myclimate is an alternative to the fossil driven electricity fuel mix by sun power and furthermore creates local employment, a visitor center and a fund for social activities.

myclimate is one of the world’s quality leaders in voluntary CO₂-​compensation measures.

Initiatives on our route
Emission calculator

Calculate your emissions

In collaboration with myclimate, a Swiss-based organization, we provide pilots an easy way to calculate their emissions when flying piston-powered aircraft.

We calculate total flight emissions as the sum of:

  • Direct CO2 emissions resulting from the combustion process in the engine

  • Indirect emissions as a result of fuel production and distribution

  • Direct non-CO2 emissions, e.g. aerosols

  • Emissions as a result of infrastructure provision (aerodromes)

The Diamond Aircraft DA50 RG

Diamond Aircraft's DA50 RG is the platform of choice for Diamondo Earthrounding.


The jet fuel capabilities of the Continental Aerospace Technologies CD-300 engine allows the DA50 RG to be fuelled up close to everywhere. On top, it runs more fuel-efficiently when compared to conventional AVGAS-burning piston engines, saving many gallons of fuel along the way!

Sustainable Aviation Fuels

When compared to traditional jet fuels, Sustainable Aviation Fuels (SAF) significantly reduce carbon emissions. SAF can be produced from various sources, such as waste or renewable foodstock. SAF's advantage over electric energy sources is its high energy density by mass; 60-100x higher than Li-ion batteries.

Direct Air Capture

Until major leaps in technology will allow aviation to operate at zero emissions, filtration of carbon dioxide from our atmosphere for storage or further use is crucial to decarbonize the sector.  

How expensive is SAF?


SAF is a “Drop-In Fuel”, which is mixed with fossil “JET A-1” kerosene. The mixing is necessary, as some engines still require a certain amount of JET A-1 to run smoothly. The mixing ratio is up to 50% and depends on the SAF production method. Assuming a mixing ratio of 50/50 and the SAF being produced by synthetic means (Power-to-Liquid), its use is currently approximately 5x more expensive than relying solely on fossil JET A-1.

Why not just plant trees?

While afforestation is one of the most affordable ways to compensate for CO2 emissions, our planet simply does not offer sufficient space to offset our fossil carbon emissions solely through forests. Besides being an alternative in areas trees will not grow, such as Iceland, Direct Air Capture offers the benefit of being able to reuse the captured CO2, e.g. for the production of SAF.
