[ ์์ฆ๋ค ์๊ณ ๋ผ / ํฉ์ฐฌ์ ๊ธฐ์ ] Just when you thought that your digital lifestyle was environmentally harmless, studies show that your online presence leaves behind an offline footprint.ย
Contrary to popular belief, watching Netflix and video calling through Zoom – everyday things digital consumers do – contribute to carbon dioxide emissions in the same way factories and cars do. As such, your online habits dictate the impact you have on the environment.
Thatโs not to say the consequences of digital consumption are far worse than those of non-digital, offline activities such as driving, but rather, the duality of internet-streaming services and their impact, once thought to be solely intangible, should not be overlooked.
โAt large, digital technologies account for almost 4% of world-wide greenhouse gas emissions. In short, because the internet heavily relies on data centers and physical servers that are operated through undersea cables and power sources that expend great quantities of fossil fuels, the more internet we use, the more CO2 is created.ย As a matter of fact, a recent 2020 study presents a startling observation: the type of activity we do on the internet largely determines our carbon, water, and land footprint. In relevance to our world today, Purdue and Yale University find that streaming data-intensive services like Zoom and Netflix emit more than twice the amount of CO2 than using Facebook and Whatsapp, and similarly, the maximum water and land footprint from these video platforms are three-fold of others.

Moreover, even within these web-services, we may unconsciously make decisions that further accumulate to our environmental footprint. For example, streaming a Netflix series in high-definition rather than standard-definition can increase the energy consumption by 86%. Similarly, while the average 1 hour Zoom video-conference can emit up to 1 kg of CO2 and use almost 12 liters of water, scientists have found that turning your camera off for an hour can reduce net footprint by a significant 96%.
Indeed, with the increasing pool of digital consumers, Kavesh Madani, an environmental scientist at Yale, says, โWithout your consent, these platforms are increasing your environmental footprint โฆ If you just focus on one type of footprint, you miss out on others that can provide a more holistic look at environmental impact.โ
These digital services have served as indispensable parts of online infrastructure, especially during the pandemic where learning and work is done virtually. They have become a necessity to everyday life, and with a 20% increase in Internet traffic since the outbreak in March 2020, by the end of 2021, according to Sciencedirect, an additional 71,600 trees will be needed to neutralize carbon emissions and 300,000 olympic-size swimming pools in order to compensate for water depletion.
