Evans – who came second at the Tour in 2007 and 2008 before winning the event in 2011 – will not take part in cycling's most famous race this year.
The 37-year-old will instead focus his energies on the Giro d'Italia, which begins in Belfast on May 9.
The BMC man leads the Giro del Trentino with one day remaining and says he is fine with his team's decision to go in a different direction at the Tour de France.
"I'm happy to give it everything for the Giro d'Italia for now," Evans told Cycling News.
"I might be sad when I have to watch the Tour on television but for ten years my whole life rotated around the Tour de France.
"But to win the Tour, you need the support of everyone…yourself, the team, the sponsors and everyone behind you. If you don't have that, it's almost a waste of time doing it.
"The team decided that I wasn't doing the Tour and that I should focus on the Giro. I didn't have a lot of choice but I accepted it and realised that it was a weight off my shoulders.
"Ten years is a long time and fortunately I managed to win one Tour, so I have to be satisfied with that.
"I've thought back to my first Giro d'Italia in 2002 and I wanted to come back and prepare properly for it really well. We've got a strong team backing me and I hope to do well."
Evans feels his experience could be helpful in his Giro campaign and insists that those doubting his fitness spur him on.
"I find the motivation by people saying I'm a year older," he added.
"But age is just a number that I'm sometimes judged on. But I think people can see that I'm still motivated to race.
"I've still got the same love for the sport, the same desire to do well and the same passion as when I was 25.
"Now perhaps my experience helps me. There's nothing I can do about my age, it goes up for everyone. I just don't think about it, even if I won't be racing at a high level when I'm 40."
