Five ways to make music streaming better for the climate

One of the most interesting (and also successful) campaigns Kpop4planet has organized shines a light on the carbon footprint of music streaming. Aware that K-pop fans stream significantly more than average (sometimes over five hours a day!) to support their favorite artists, the group successfully campaigned to get Korea’s largest domestic streaming platform to pledge to use 100% renewable energy by 2030.

I have to admit, before working on this story, it didn’t really cross my mind that streaming music could be so polluting. Streaming an album more than 27 times uses more energy than it takes to produce a CD, according to researchers, but it’s surprisingly hard to draw a conclusive answer on whether streaming is more polluting than CDs or records overall. What we do know is that since the carbon emissions associated with streaming are produced in faraway data centers and through invisible data transmissions, the problem is harder to pin down.

During my reporting, I talked to several experts about how to correctly understand the climate impact of music streaming, and one thing became clear: It all comes down to how we stream—the content, the device, the length, etc. They also recommended a bunch of things that any music streaming user can do to leave a smaller carbon footprint.

So here are the things you can do if you are a heavy music streamer:

1. Use small devices instead of big TVs. 

A major part of streaming’s carbon footprint comes from the device that’s used to play the music or video. And some are much more power hungry than others. A 50-inch LED TV consumes 100 times more electricity than a smartphone when used for streaming, according to the International Energy Agency. It also consumes more electricity if the screen stays on, displaying videos or lyrics, rather than just playing the audio. So using a smartphone to stream cuts energy consumption to a minimum.

2. Wait longer to buy a new phone. 

Yes, smartphones are designed to be pretty energy-efficient to use, but manufacturing them is another story. “In the life-cycle analysis of a phone, 85% to 90% of its lifetime energy occurs in its production,” says Laura Marks, a professor in media art and philosophy at Simon Fraser University. The manufacturing process usually involves fossil fuels, plastics, and minerals that could pollute the environment.
