So without your consent, these platforms are increasing your environmental footprint," said Kaveh Madani, who led and directed this study as a visiting fellow at the Yale MacMillan Center. "Banking systems tell you the positive environmental impact of going paperless, but no one tells you the benefit of turning off your camera or reducing your streaming quality.

As expected, the more video used in an application, the larger the footprints.īecause data processing uses a lot of electricity, and any production of electricity has carbon, water and land footprints, reducing data download reduces environmental damage. The team estimated the carbon, water and land footprints associated with each gigabyte of data used in YouTube, Zoom, Facebook, Instagram, Twitter, TikTok and 12 other platforms, as well as in online gaming and miscellaneous web surfing.

The additional water needed in the processing and transmission of data would also be enough to fill more than 300,000 Olympic-size swimming pools, while the resulting land footprint would be about equal to the size of Los Angeles. If the trend continues through the end of 2021, this increased internet use alone would require a forest of about 71,600 square miles - twice the land area of Indiana - to sequester the emitted carbon, the study found. "If you just focus on one type of footprint, you miss out on others that can provide a more holistic look at environmental impact," said Roshanak "Roshi" Nateghi, a Purdue professor of industrial engineering, whose work looks to uncover gaps and assumptions in energy research that have led to underestimating the effects of climate change.Ī number of countries have reported at least a 20% increase in internet traffic since March.

The findings are published in the journal Resources, Conservation & Recycling. The study, conducted by researchers from Purdue University, Yale University and the Massachusetts Institute of Technology, is the first to analyze the water and land footprints associated with internet infrastructure in addition to carbon footprints.

Streaming content in standard definition rather than in high definition while using apps such as Netflix or Hulu also could bring an 86% reduction, the researchers estimated. Just one hour of videoconferencing or streaming, for example, emits 150-1,000 grams of carbon dioxide (a gallon of gasoline burned from a car emits about 8,887 grams), requires 2-12 liters of water and demands a land area adding up to about the size of an iPad Mini.īut leaving your camera off during a web call can reduce these footprints by 96%. A new study says that despite a record drop in global carbon emissions in 2020, a pandemic-driven shift to remote work and more at-home entertainment still presents significant environmental impact due to how internet data is stored and transferred around the world.
