GreenTabs - Close Tabs, Save the Planet

The mission of GreenTabs is to create simple, meaningful ways for everyone to engage with climate action daily. We believe that small digital habits can have a real environmental impact when multiplied across millions of users.

The Digital Carbon Crisis

We often think of our digital lives as weightless and immaterial. But every click, every tab, every browser action carries a hidden carbon cost. The digital world produces more greenhouse gas emissions than the aviation industry, and that number is growing.

One open browser tab emits approximately 7 grams of CO₂ per hour. For someone who keeps dozens of tabs open while working, that's equivalent to leaving a light bulb on for hours. Multiply this across millions of workers worldwide, and the impact becomes staggering.

The average Chrome user keeps 11.4 tabs open simultaneously. Many are forgotten, passively consuming energy in data centers thousands of kilometers away. These "zombie tabs" serve no purpose but continue to harm our planet.
