The Guardian article has a grabby title: “Streaming’s dirty secret: how viewing Netflix top 10 creates vast quantity of CO2.” The article starts by saying “the carbon footprint produced by fans watching a month of Netflix’s top 10 global TV hits is equivalent to driving a car a hefty distance beyond Saturn.”
This is actually a bit of a distortion. As Treehugger’s Matt Alderton noted in his post “What Is the Carbon Footprint of Your Netflix Habit? New Study Sheds Insight,” the Carbon Trust estimated that an hour of streaming generated the equivalent of about 55 grams of carbon dioxide (CO2) per hour in Europe,
George Kamiya of Carbon Brief notes “the relatively low climate impact of streaming video today is thanks to rapid improvements in the energy efficiency of data centres, networks and devices.” Every year the numbers get better, and the International Energy Agency has reduced its estimate of power consumption down to 36 grams of CO2 per hour.
When researching my book, “Living the 1.5 Degree Lifestyle,” I tried to figure out the footprint of an hour of leisure time watching videos and using computers. I wrote:
I assumed the streaming industry was causing a dramatic increase in the number of shows being produced worldwide to fill all those pipes and noted that the American Time Use Survey found the average American watches 2.81 hours per day. It notes: “We have to include our share of the carbon footprint for the entire entertainment industry.”
What’s behind the screen during those 2.81 hours of TV? Lauren Harper of the Earth Institute wrote:
I multiplied all that carbon by the number of productions and divided it by the number of subscribers, and even with all the productions and all the servers, I came up with a grand total of 50.4 grams of CO2 per hour. Other people’s mileage may vary; if you live in a part of the country with dirty power, your ISP may have a higher footprint and so will your big TV. But it still probably isn’t a big number. Sitting on the couch watching TV is pretty low on the carbon-emitting scale of things that we do.
One of the main conclusions I came to in my book is that worrying about 36 grams is silly and counterproductive. You can multiply anything by a big enough number and drive “the approximate equivalent of the current distance between Earth and Saturn.” But the real problem is the number of people who are driving at 480 grams per mile. Multiply that by the billion cars on the road and you will get to Alpha Centauri.
So sit back and enjoy the show. We have much bigger things to worry about.
