TikTok’s Carbon Footprint: Bigger Than Greece? The Shocking Environmental Cost of Social Media
In an age where technology dominates our daily lives, our reliance on social media has created an invisible but alarming environmental challenge. Among the most popular platforms, TikTok has emerged as not just a cultural phenomenon but also an unexpected climate concern. A recent study reveals that TikTok's annual carbon emissions may now exceed those of Greece, a startling revelation that prompts us to rethink our relationship with digital media.
The Data Behind the Claims
According to a study by Greenly, a Paris-based carbon accounting firm, TikTok’s carbon emissions in the United States, United Kingdom, and France for 2023 are estimated at 7.6 million metric tonnes of carbon dioxide equivalent (CO2e). This figure eclipses the emissions of other platforms like Twitter/X and Snapchat in the same regions and rivals that of small nations. Globally, TikTok's emissions are projected to reach a staggering 50 million metric tonnes of CO2e — roughly on par with Greece's 51.67 million tonnes in 2023.
This startling comparison underscores the carbon cost of TikTok’s 1 billion-strong user base. Unlike Instagram, which has nearly double the users but a lower carbon footprint, TikTok’s highly engaging algorithm keeps users glued to their screens longer. On average, users spend 45.5 minutes daily on TikTok, compared to Instagram’s 30.6 minutes. This extended usage significantly amplifies TikTok's carbon impact.
The Hidden Costs of Addictive Algorithms
TikTok’s algorithm is central to its appeal and its environmental toll. The platform’s unique "For You Page" serves a continuous stream of personalized, short-form videos designed to captivate users. Alexis Normand, CEO of Greenly, noted that this "addictiveness also leads to individuals increasing their carbon footprints."
The platform’s design demands significant energy to power its data centers, which account for 99% of TikTok’s total emissions. These centers support the massive video processing, storage, and delivery requirements that define TikTok’s experience. Every minute spent on TikTok emits an estimated 2.921 grams of CO2e, slightly less than YouTube (2.923 grams) but more than Instagram (2.912 grams). Over a year, the average TikTok user generates approximately 48.49 kg of CO2e, equivalent to driving a gasoline car 123 miles.
Comparing Social Media’s Carbon Footprints
The environmental impact of social media platforms varies widely. YouTube users, who emit 40.17 kg of CO2e annually, trail TikTok but still contribute significantly to global emissions. Instagram users fare slightly better at 32.52 kg of CO2e annually. When considered across billions of users globally, these seemingly small individual footprints combine into a massive carbon problem.
Data from Greenspector shows that social media use contributes approximately 262 million tonnes of CO2e globally, equating to 0.61% of total global emissions. To put that in perspective, this is roughly equivalent to the carbon emissions of Malaysia. TikTok, with its immense popularity and intensive energy use, is a key contributor to this global tally.
Corporate Accountability: TikTok's Promises and Pitfalls
TikTok has pledged to achieve carbon neutrality by 2030, with initiatives such as “Project Clover” aiming to reduce its emissions. In 2023, the company launched a renewable energy-powered data center in Norway, a €12 billion facility designed to minimize environmental impact. While this is a promising step, critics argue that it is insufficient given the scale of TikTok’s emissions.
Transparency remains a concern. Unlike Meta and Google, which regularly publish detailed sustainability reports, TikTok offers limited insight into its emissions and environmental initiatives. This opacity has raised questions about the platform’s true commitment to sustainability.
Broader Implications for Social Media
TikTok is not alone in grappling with the environmental consequences of its operations. Many tech giants have pledged to transition to renewable energy for their data centers. However, a report by The Guardian revealed that some firms understate their emissions by as much as 662% through the misuse of renewable energy credits (RECs). This casts doubt on the sincerity of corporate sustainability efforts across the tech industry.

Social Media’s Cumulative Impact
Social media’s carbon footprint is a growing issue. With over 4.33 billion users worldwide spending an average of 145 minutes daily on platforms like TikTok, Instagram, and Facebook, the cumulative environmental impact is enormous. Greenspector calculates that an average social media user generates around 60 kg of CO2e annually — equivalent to driving the 535 km distance from London to Edinburgh in a small car.
While individual actions like reducing social media use can make a small difference, systemic changes are necessary to address the broader issue. This includes greater transparency from tech companies, stricter regulations, and accelerated adoption of renewable energy solutions.
Can TikTok and Social Media Be Sustainable?
As TikTok faces mounting scrutiny, its response will set a precedent for the industry. Achieving carbon neutrality by 2030 is an ambitious goal, but meeting it will require substantial investment in green technologies and operational changes. Beyond corporate commitments, governments and regulators must play a role in holding tech companies accountable.
For users, the revelations about TikTok’s environmental impact offer a new reason to reconsider their digital habits. While scrolling through endless videos may seem harmless, the cumulative carbon cost adds up. Tools like Compare the Market’s social media carbon calculator can help individuals quantify their footprint and make more informed choices.

A Collective Responsibility
The intersection of technology and sustainability presents a challenge that requires collective action. While tech giants like TikTok bear the primary responsibility, users, regulators, and policymakers must also contribute to building a more sustainable digital future. By addressing the carbon footprint of social media, we can take a significant step toward mitigating the environmental impact of our increasingly digital lives.
