With a violin on his back and maps in his bag, Dan Hodd left Spain a month ago and was cycling through busy as he heads to the climate talks in that he firmly intends to reach without flying.

Avoiding flying is not only part of Hodd’s message to delegates at COP27. His trip to Egypt is part of a long-term project to visit 100 countries in 10 years without flying, busking with his violin to earn enough to go on.

Now in his sixth year of travel, the seasoned traveller and graduate in music psychology told Reuters that pollution on the road was one of the main challenges for .

“The smell of petrol, it just dominates everything” he said, adding that he often had to ride with his mouth covered despite high temperatures.

“We live on a planet that is not built for sustainable travelling”, he said.
