EMISS — SoundCloud player with CO₂ heatmap
The hidden cost of streaming
Every song you stream burns carbon.
Music feels weightless, but it isn't. Every track you stream travels from a remote data center, through global networks, into your device — and each of those steps consumes electricity. Today, digital streaming services are responsible for an estimated 200–350 million tonnes of CO₂ per year, more than the entire aviation industry of some countries.
Why EMISS exists
Streaming is one of the most ordinary things you do. You press play on the bus, at your desk, before you fall asleep. It feels like nothing. It costs nothing. And that feeling — of music being free, infinite, weightless — is the most carefully designed lie in the digital world.
The servers that store your music never switch off. The data centres that deliver your stream consume as much electricity as small countries. The carbon emitted by music streaming alone is growing every year. And not one platform shows you that number.
EMISS exists to close that gap. Not to make you feel guilty. Not to ask you to stop listening. But because you deserve to know what the things you love actually cost — and because knowing is the first step toward demanding something better.
We built the most energy-efficient streaming platform we could. And then we showed you exactly what it still costs. Because if we're serious about change, it starts with honesty.
How EMISS is less energy effective
Every design decision inside EMISS is an energy decision. The interface runs on a near-black default state — not as a style choice, but because dark screens consume significantly less power on the devices people actually use. There are no animations that don't carry meaning, no decorative elements, no video, no visual noise. Only what is necessary.

There are no playlists on EMISS and no autoplay. Every song is a choice you make consciously — you pick what plays next, and when you stop choosing, the music stops. That single principle puts you back in control of something that was quietly running without you on every other platform.
When nothing is playing, the interface returns to black, still and quiet, drawing as little power as it can.
EMISS does not claim to be zero emissions — streaming will always have a cost, and this platform will always be honest about that. What it offers is the most energy-considered streaming experience that can currently be built, designed at every level to consume only what is absolutely necessary.
How you can listen lighter
- Download your favorite tracks instead of re-streaming them.
- Listen on Wi-Fi rather than mobile data when possible.
- Turn off video when you only want the audio.
- Pause when you're not actively listening.
