The internet is the world’s largest coal-powered machine.
The internet should be a global public good—healthy for the planet and for the people who use it.
We need a fossil-free internet. By 2030.
The Green Web Foundation tracks and accelerates the transition to a fossil-free internet. You can use our open dataset of websites that run on renewable energy—accessed over 2 billion times. You can green your internet practice and your organization with our tools and resources. And together, we can advocate for a more sustainable and just internet.
