Coldplay had vowed that they will not tour till they crack the code to do it while making environmentally sustainable choices. That was about two years ago. The band, however, seems to be ready now; the British group announced a world tour on Thursday, starting in March with Costa Rica.

Part of the power required for this show would come from the very fans in the audience.

Singer Chris Martin told the BBC in an interview that fans will be on “kinetic flooring.”

“When they move, they power the concert,” he said. “And we have bicycles too that do the same thing.”

This is a part of the 12-point plan that the band has agreed upon to tour in a way that aligns with their attempt at sustainability.

“The more people move, the more they’re helping. You know when the frontman says, ‘We need you to jump up and down’? When I say that, I literally really need you to jump up and down. Because if you don’t, then the lights go out,” Martin said.

They also intend to take other measures. They have chalked out an itinerary that calls for minimal air travel and would using sustainable aviation fuel when flying is unavoidable. Venues have also been asked to indulge in sustainable practices such as installing aerated taps and low-flushing toilets to prevent water wastage.

Their sets are to be built with materials with environmental credentials, like bamboo. Effects like lasers and lighting have been modified to be energy efficient. Even the details down to the LED wristbands have been considered; they will be made from 100% compostable, plant-based materials and will be reused every night.

Fans would also cause carbon emissions to get to the venue. To counter that, an app will let fans plan their journeys to and from the show with the lowest possible emissions. They would also be given a discount code to use at the venue if they commit to low-carbon travel.

But Martin admitted they had not figured out how to cut the environmental impact of some parts of touring.

“In some areas, there’s still not enough possible, like how do you get people to a venue without consuming any power? That’s still really hard,” he said.

“Or flying – there’s still a lot of offsetting we have to do because even sustainable aviation fuel isn’t good enough yet.

“So, we know where we still have a long way to go. But in terms of the show itself, the whole show is powered from renewable energy, which is amazing.”

The singer admits that all backlash that would come their way would be called for, there is still a long way to go. However, the band does not want to lose the personal connect with the fans that comes only via tours. They only hope that, in a few years’ time, they have “slightly shifted the status quo of how a tour works.”

This would be the first tour the band embarks on after about four and a half years of their self-imposed ban.
