Cloud gaming with PlayStation titles generates more carbon emissions than playing with physical discs and downloaded copies, study says
- Cloud gaming lets players stream games without storing them on their consoles, computers or tablets
- Constant streaming means cloud gaming uses a lot of energy, but it might have a smaller carbon footprint for shorter games lasting a few hours
If you need to convince someone to let you cosy up at home and play games instead of going out, tell them it’s better for the planet. But don’t stream those games from the cloud if you want to really minimise your carbon footprint.
Compared with people who use transport to go to the cinema or play sports, consumers who stay indoors and play PlayStation games produce fewer carbon emissions, according to a Sony-sponsored academic study.
Conducted at the University of Surrey and based on data in Europe, the research shows that over the course of five years, a person who only downloads games to play on a PS4 generates about the same amount of carbon emissions as three train trips between London and Glasgow.
But while gamers might have a smaller carbon footprint than habitual film-goers, the size of that footprint varies by how they play.
On average, cloud gaming emits roughly triple the carbon dioxide of downloads and 2.7 times that of playing from discs.
That’s because cloud gaming requires constant on-demand streaming from a remote data centre, whereas games downloaded to a console or bought on discs are stored locally. Using the internet, gaming servers and home routers consume more energy, the research said.
However, the study does not appear to take into account remote server usage when people play multiplayer games online. But it does account for downloading patches and updates for players using game downloads and discs. The result is that server usage for gameplay is only accounted for with people using cloud gaming.
