Five ways to make music streaming better for the climate

This week, we are taking a short break from China and turning to its neighbor South Korea instead. As K-pop sweeps the world and accumulates a massive, devout fan base, these fans have been turning their power into action. Today, I published a story about Kpop4planet, a group of volunteers who are using K-pop’s influence to hold large corporations accountable for their carbon footprints.
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.
“So if I were to make a couple of recommendations, one of them would be to keep your devices for as long as possible, because that’s a huge, huge component of streaming that’s often overlooked,” she says.
3. Return to digital downloads, and only use streaming in selected situations.
While few people still download music files today, experts have agreed that one of the most climate-friendly ways to listen to music is to keep a digital file of your favorite song and return to it repeatedly.
We also need to change our mindset about treating streaming as the only way to listen to music, says Joe Steinhardt, an assistant professor in the music industry program at Drexel University. “The first and the easiest [suggestion] is to think about streaming music like Styrofoam plates or plastic forks. It doesn’t mean I never use those; it’s just that I don’t eat every meal off of them,” he says. If you are listening to a large variety of music, maybe streaming is the best choice; if you are listening to a few songs repeatedly, go for a digital download or even an old-fashioned CD.
4. Push for streaming platforms to do their part.
Climate action is not just about individual responsibility—it also means pushing corporations to do better. Just as Kpop4planet chased after Melon, Korea’s largest domestic music streaming service, you can also hold your favorite music streaming service accountable.
A big part of that is figuring out where the platforms’ data centers are, as these can account for a third to a half of streaming’s carbon footprint, according to Marks. These gigantic facilities draw significant amounts of electricity. If they can switch to using renewable energy, that will be much more meaningful than any action one individual can take. It’s also important not to fall for empty promises, and to seek specific plans on where and how they plan to source renewable energy.
5. Cherish music and resist overconsumption.
Many experts mention the Jevons paradox, which states that increasing the efficiency with which a resource is used can lead to more total consumption. In the case of streaming, this means that even if the technology can become more energy-efficient on a per-song basis, the business model and the sheer convenience often encourage users to listen to more and more songs without considering the climate consequences.
To resist that mindset, Marks suggests, we should cherish listening to music more. “Instead of streaming all day, it could mean really enjoying the performance of a song—just listening to it a couple of times and then talking with your friends about it,” she says.
My conclusion? It’s never too late to become aware of the climate impact of music streaming and think about what we can do to make it even just a little greener.

Lost in translation
Morowali, a remote, agricultural community in Indonesia, has been transformed into a hub for heavy industry by the entrance of a Chinese company, according to the Chinese magazine Sanlian Lifeweek. Tsingshan Holding Group, a Chinese steel and nickel company, was instrumental in investing in and setting up the Indonesia Morowali Industrial Park (IMIP), where a rich local reserve of nickel ore is converted into high-purity nickel sulfate that’s essential for electric vehicle batteries.
IMIP has created at least 100,000 jobs and contributed significantly to Indonesia’s economy, but it has also led to environmental and health challenges for local communities. Concerns about air and water pollution, garbage disposal, and worker safety have intensified following an explosion in 2023 that killed eight Chinese workers and 13 Indonesian workers. Now, local workers are organizing to sit down with management and push for changes in worker welfare.
