Next Tuesday, April 22, will mark the 55th anniversary of Earth Day, a celebration launched in 1970 to bring attention and grassroots energy to environmental issues. But the days that immediately follow it, April 23 through 27, will mark the eighth annual offering of a relatively under-the-radar series of climate events: Earth Night.

Organized by a small volunteer group called DJs for Climate Action, Earth Night is a global initiative that brings climate and environmental messages into dance halls, bars, clubs, and other nightlife venues.

The idea started with a campaign by producer and DJ Sam Posner (also known as Sammy Bananas). Around 2009, he launched a holiday fundraising campaign for DJs to buy carbon credits to offset the emissions of the frequent flights they take to work at parties and events all over the world.

“He sent it to me and I was like, ‘Oh, this is really interesting,’” said Eli Goldstein (Soul Clap), a fellow music artist who’s now the president of DJs for Climate Action. “At that time I was flying a lot, and it was the first time a light bulb went off, that there was a negative side of all the flying around the world DJing.” Taking a flight is one of the most carbon-intensive activities any individual can do — and as long-distance, often international travel is a routine part of many DJs’ jobs, they can rack up some high carbon footprints.

Goldstein had long been interested in environmental issues. He even sang at Earth Day celebrations as a schoolkid. When he encountered Posner’s carbon-credits campaign, he had what he described as “an epiphany” that living his dream as a DJ wasn’t fully in line with his environmental values.

The end-of-year fundraisers continued for several years, under the banner of DJs Against Climate Change, before the group decided it wanted to do something bigger. Focusing only on the carbon footprint of traveling felt like a missed opportunity to take advantage of the unique skills the artists had to bring to the movement.
