The options, whether you like them or not:
- Do not travel.
You might even get things done with a video or phone call.
- Train. Pro-tip: book early and the pricing will be lower.
- Bus. (Flixbus also has low rates for early birds)
- Car share , even via https://www.blablacar.nl/ or https://www.snappcar.nl/
- Taxi, Uber has an option to get electric cars only 🙂
- Hybrid ( a combination )
- Take the plane / cruise-ship anyway, but compensate the footprint
Also: when taking planes: (based on European trip-distances) the most pollution comes from takeoff. Avoid flights with plane-transfers as you will pollute twice (or more) to get up in the air. Fly non-stop if you can, see screenshot from google flights
Planes are a nightmare, and compensation of the footprint may sound nice, but how sure are we that the forests that will be planted won’t be planted anyway or that they will exist for a lifetime?
Many people will just not know how great the international trains network is and take a plane from Amsterdam to , say Berlin or Paris, while the high speed train saves you headaches and runs on pure electricity.
