![]() ![]() The figures come from a July 2019 report by the Shift Project, a French thinktank, on the “unsustainable and growing impact” of online video. Contrary to a slew of recent misleading media coverage, the climate impacts of streaming video remain relatively modestĪ number of recent media articles, including in the New York Post, CBC, Yahoo, DW, Gizmodo, and BigThink, have repeated a claim that “the emissions generated by watching 30 minutes of Netflix is the same as driving almost 4 miles”. ![]() The updated charts and comparisons also include the corrected values published by The Shift Project in June 2020, as well as other recent estimates quoted by the media. As a result, the central IEA estimate for one hour of streaming video in 2019 is now 36gCO2, down from 82gCO2 in the original analysis published in February 2020. Update : The energy intensity figures for data centres and data transmission networks were updated to reflect more recent data and research. But slowing efficiency gains, rebound effects and new demands from emerging technologies, including artificial intelligence (AI) and blockchain, raise increasing concerns about the overall environmental impacts of the sector over the coming decades. The relatively low climate impact of streaming video today is thanks to rapid improvements in the energy efficiency of data centres, networks and devices. ![]() These exaggerate the actual climate impact by up 90 times. Yet, contrary to a slew of recent misleading media coverage, the climate impacts of streaming video remain relatively modest, particularly compared to other activities and sectors.ĭrawing on our analysis and other credible sources, we expose the flawed assumptions in one widely reported estimate of the emissions from watching 30 minutes of Netflix. Streaming services are associated with energy use and carbon emissions from devices, network infrastructure and data centres. In this commentary, we examine the carbon footprint of these services. With few options left for entertainment, streaming services are taking off. Here's how to download and redownload Netflix shows and movies.A version of this commentary was originally published in Carbon Brief.Įven before millions were confined to their homes by a global pandemic, improvements in internet connections and service offerings had led to an exponential increase in the use of streaming video around the world. This isn't really something to worry about, though - as long as you're connected to a WiFi network, you can download it again just as quickly - or choose a different title to download. When a download has expired, you will see an orange exclamation point and the word expired next to it. Most downloads last for seven days if a download will expire in fewer than seven days, Netflix displays the days or time remaining for it beside the title on the app's Downloads page.Īnother common time limit is that many downloads will expire 48 hours after you press play on the title, after which point you'll have to redownload it, if the option is available. The amount of time that downloads can remain on your device can vary by license, or even by title - and some titles don't allow downloading at all. Now, naturally Netflix downloads can't last forever - that would essentially mean that you owned the movie, which is not how streaming services work. The amount of time your Netflix downloads last varies by title and license ![]()
