Greg Hill is a ski tourer—an extreme ski tourer and endurance athlete who is best known for setting a new record by climbing and skiing over 600,000 vertical meters in one year (2010). Since then, he has gained a new perspective on how he approaches the mountains. At a time when students and young people are taking to the streets for 'Fridays for Future', Greg has come to the realization that he doesn't have to jet across the globe to climb mountains. The Canadian skier is no longer flying to his destinations, opting instead for an electric car. His goal is to climb the next 100 peaks without burning any fossil fuels. But the question is: will it make a difference?
