For most international travellers, flying is the only realistic way to reach Mongolia. We recognise that those flights come with a significant carbon footprint and that offsetting does not remove or undo those emissions.
If you would like to take responsibility for the impact of your international flights, you can use the calculator below to estimate your emissions and make a contribution.
Your contribution supports independently verified Plan Vivo projects, designed to deliver long-term benefits for climate, biodiversity and local livelihoods.
We know offsetting is not a perfect answer. Reducing emissions matters most. But where emissions cannot currently be avoided, we believe in taking practical action rather than ignoring the impact.

Not all airlines have the same carbon impact.
Atmosfair is an independent climate NGO that compares the carbon efficiency of major airlines through its Airline Index.
If you have a choice of airline when flying to Mongolia, the index can help you compare their relative performance. Airlines rated A are among the most carbon efficient, while those rated G are among the least efficient.
