Since 2010, global Internet traffic has exploded—growing fifteen‑fold in just a decade. That surge isn’t free: in 2020, the information‑and‑communications‑technology sector alone produced 7.3 % of all global CO₂ emissions and consumed 3.9 % of the world’s electricity. Every video streamed, email sent, and page loaded adds up to a significant—and growing—carbon footprint.
It’s easy to overlook the environmental impact of browsing the web, but every single click—every page you load—leaves a footprint on the planet. While it may seem small, the cumulative effect of billions of clicks across the globe is staggering.
For instance, each average webpage generates between 0.8 to 1.76g of CO₂ (source: Green Web Foundation). To put that into perspective:
These seemingly negligible emissions multiply fast when you consider the billions of people accessing the internet daily. And it’s not just about the number of clicks—content-heavy pages, like those with videos or high-res images, contribute much more CO₂ than simpler, text-based pages.
When you think of major carbon emitters, planes probably come to mind. After all, air travel has a reputation for being one of the most environmentally damaging industries. But what if we told you that the internet—the very thing you use every day—actually emits more greenhouse gases than global aviation?
As of 2020, the internet now accounts for 3.7% of global greenhouse gas emissions, which is greater than the emissions from all commercial planes combined. In fact, the entire aviation industry contributes around 2-3% of global CO₂ emissions, while the digital economy’s footprint continues to grow year after year.
By 2030, the carbon footprint of the digital sector is expected to triple — not because we’re careless, but because the digital world is growing at a breakneck pace, and sustainability simply hasn’t kept up.
What does “tripling” look like? If digital emissions triple by 2030, they could exceed 10% of global CO₂ emissions — that’s more than the entire global transportation sector today. Imagine:
As more services move online — from banking and education to healthcare and entertainment — our digital infrastructure becomes one of the fastest-growing polluters on the planet.
This isn’t a future problem. It’s already happening. And by 2030, the damage could be locked in — unless we act now.
