The environmental sustainability of digital content consumption is a critical issue as internet access has reached 60% of the global population, with users spending over 40% of their waking life online. This study assesses the environmental impacts of digital content consumption, finding that current global average consumption could account for approximately 40% of the per capita carbon budget consistent with limiting global warming to 1.5°C, as well as around 55% of the per capita carrying capacity for mineral and metal resources use. Decarbonizing electricity could reduce climate impacts to 12% of the per capita carrying capacity by 2030, but concerns about mineral and metal resource use remain. A combination of rapid decarbonization and measures to reduce raw material use in electronic devices is essential to prevent Internet demand from exceeding Earth's carrying capacity. The study quantifies the environmental impacts of digital content consumption, including web surfing, social media, video and music streaming, and video conferencing. The annual carbon footprint of the global average user is 229 kg CO₂-eq per year, equivalent to 3-4% of the per capita anthropogenic greenhouse gas emissions. The impact varies significantly based on the electricity mix used, ranging from 146 kg CO₂-eq per year in Norway (with hydropower) to 327 kg CO₂-eq per year in India (with fossil fuels). The study also assesses the environmental impacts of digital content consumption against the Earth's carrying capacity, finding that it could require 55% of the per capita carrying capacity for mineral and metal resources use, 20% for freshwater eutrophication, and over 10% for particulate matter, ecotoxicity, and fossil resources use. The embodied impacts in end-user devices are the largest contributors, accounting for 92% of mineral and metal resources use. The operational impacts vary with the electricity mix, with Norway having the lowest impacts and Australia and Poland the highest in freshwater eutrophication. The study highlights the need for rapid decarbonization of the power sector and measures to reduce the use of fresh raw materials in electronic devices. Extending the lifetime of electronic devices can significantly reduce mineral and metal resource use. The findings suggest that digital content consumption could leave little room for impacts linked to basic needs like food and transport, raising concerns about the sustainability of the current system. The study emphasizes the importance of a holistic approach to mitigate the environmental impacts of digital content consumption.The environmental sustainability of digital content consumption is a critical issue as internet access has reached 60% of the global population, with users spending over 40% of their waking life online.
