German study highlights carbon footprint of video streaming By FRANK JORDANStoday
BERLIN (AP) — Streaming high-definition videos and games can result in significant greenhouse gas emissions, depending on the technology used, according to a German government-backed study released Thursday.
The report published by Germany’s Federal Environment agency calculated the amount of carbon dioxide produced by data centers where material is stored for streaming, and by the transmission technology used to get it to consumers.
It concluded that streaming video over fiber optic cables results in the lowest amount of CO2 emissions — 2 grams per hour. Using copper cables produces twice that amount, while 3G mobile technology results in a hefty 90 grams of CO2 per hour. ADVERTISEMENT
The report’s authors said streaming over next-generation mobile technology, known as 5G, would result in carbon dioxide emissions of 5 grams per hour, suggesting that widespread rollout could help cut energy consumption.
