The UK Cabinet Office's technology guidance encourages contractors with government contracts to reduce energy consumption by limiting the use of multimedia such as photos and videos, and using the HTML file format instead of PDF. when sharing information.
For video, contractors are required to choose lower-power multimedia formats, such as standard definition video instead of high definition. "Standard definition" here is defined as being below that of HD 1,280 x 720 pixels.
According to estimates by the Royal Society of London, watching ultra-high definition video, like 4K, consumes eight times more energy than standard definition. This is not necessary, especially for devices with small screens.
In addition, the guidelines require suppliers to remove duplicate data sets, encourage the use of low-capacity HTML file formats, and prioritize cloud computing - services that often rely on green energy.
According to the Telegraph, carbon emissions from technology activities are estimated to increase by 6% per year, despite efforts by major companies to place data centers in cold places to cut cooling and usage costs. recycled energy. Currently, many businesses are committed to the goal of carbon neutrality in their production activities in the coming time.
In fact, digital activities such as watching online videos, storing documents... have a relatively small carbon footprint compared to other activities such as transportation or heating. Even so, the growing demand of this type raises climate concerns. According to the Carbon Trust, one hour of streaming video generates about 55 grams of carbon, which is equivalent to driving about 300 meters.
Last year, the Royal Society of London also urged online service users to turn off video if they only need to listen to audio. According to the organization, that action could reduce the carbon footprint of that service by 5%.
