The impact of streaming media

Measuring the environmental impact of video streaming is a complex task as there are many identifiable parameters to consider. According to a study published by Ademe (2022), a French public agency promoting environmental sustainability and sobriety, the environmental impact of a cultural item depends mostly on how intensively it is used, whether digital or physical. Digitalisation increases the number of equipment required. This equipment, which needs a wide variety of raw materials and metals, has a significant impact on the environment.

Based on available data, the IEA estimates that one hour of video streaming consumes around 0.08 kWh of energy and emits approximately 36g of CO₂. To put this into perspective watching an average-length movie or two back-to-back hour-long episodes would require planting at least one tree in your garden to offset the emissions.

Addressing the environmental impact of video streaming is therefore crucial on both global and individual levels. There are numerous solutions to drastically reduce the environmental impact of streaming services. Implementing energy-efficient practices in data centres and transmission networks can significantly lower emissions. Individuals can also make simple conscious choices like opting for lower-resolution streaming or reducing streaming hours. Supporting and utilising renewable energy sources for streaming platforms can also contribute to a more sustainable digital landscape.

To be effective, the impact of streaming media will have to be weakened by streaming platforms themselves, as well as organisations and individuals. Professionals can contribute to the collective effort adopting eco-friendly streaming habits and promoting environmentally conscious practices within their institutions and among learners. Awareness campaigns and educational initiatives can further foster a culture of environmental responsibility within the VET sector, creating a positive impact on the environment.
