Games on Disc More Energy Efficient than Downloads

“This research investigates the carbon footprint of the lifecycle of console games, using the example of PlayStation 3 distribution in the UK. We estimate total carbon equivalent emissions for an average 8.8-gigabyte game based on data for 2010. Two delivery scenarios are compared: the first examines Blu-ray discs delivered by retail stores, and the second, games files downloaded over broadband internet.”

“Contrary to current consensus that downloaded data will result in lower carbon emissions than distribution by disc, producing and distributing an average-sized game by Blu-ray disc in 2010 resulted in approximately 50 to 90% less emissions than downloading. The estimated carbon emissions from downloading only fall below that of Blu-ray discs for games smaller than 1.3 gigabyte. The study findings serve to illustrate why it is not always true that digital distribution of media will have lower carbon emissions than distribution by physical means when file sizes are large.”
